Connective Fibrous Loose Areolar

Like other loose connective tissues, the areolar connective tissue is made up of

three different types of fibers. The three fibers are collagenous fibers, elastic fibers

and reticular fibers. All of these fibers together make up the distinct look of this

tissue. The little black dots with extensions are called fibroblast and they are found

within this type of tissue. (100X Magnification)

Adipose

This slide of a cross section of the mammalian trachea (wind pipe) contains

examples of several different kinds of tissues. In addition to the pseudostratified

columnar epithelium lining the trachea and hyaline cartilage, also seen on another

slide is an extensive area of adipose tissue in the mammary glands, which is

specialized for fat storage.On prepared slides, the fat has been removed from the

cells giving the tissue the appearance of fish net. (100X and 400X

Reticular

These slides show the connective loose reticular tissue which is found in the

kidneys, spleen, and lymph nodes. As you can see the collagenous fibers make

up a lot of the reticular tissue. The fibers form a soft ‘skeleton’ to support the

lymphoid organs, spleen, red bone marrow. Furthermore, as we can see the

reticular fibers hold the adipose tissues together as well. From the slides as well

the reticular connective tissue is not alone (and it will never be). The tissue is

combined with other cells and the fibers in its matrix are reticular fibers. (100X and

Dense Regular

The connective dense regular tissue which is found in tendons and muscle is

tightly compacted. In the slides provided, the dark spots that pop up are the nuclei

of the fibroblasts. In the 400X slide, the ‘fb nuc’ is the nucleus. Furthermore, the

collagen fibers (cf) take on a slightly wavy shape rather than a perfectly straight

one. The collagen bundles in a parallel fashion and the dense regular connective

tissue is very strong but also very flexible. (100X and 400X Magnification)

Irregular

These slides of Dense irregular connective tissue is found all throughout the body;

however, these particular images are from the skin on the palms of our hands. The

tissue is the light brown color in the slide from Austin College (the ones at 400 X).

Similar to the connective dense regular tissues, the irregular ones also contain the

tightly bound collagen fibers; however, based off the name the matrix fibers

(collagen) is not parallel like the others were. As you can see they are all over the

place.

Elastic

These slides show the dense, elastic tissue typically found in the walls of large

arteries, within certain ligaments associated with the vertebral column, and within

the walls of the bronchial tubes. The elasticity of the tissue allows for the tissue to

recoil and stretch. It also assists in the flow of blood through arteries as well as

helps with the recoil of the lungs. These particular slides are of an aorta. The thin

black lines are the elastin fibers within the tissue. This helps the tissue stretch and

then return back to its original shape. (100X and 400X)

Supportive Cartilge Hyaline

The bar in one of the images shows us how much cartilage is in the tracheal wall.

Furthermore, as you can see in the slide with the bar there is some

pseudostratified ciliated epithelium as well. Cartilage contains cells that are deeply

embedded in the matrix of fibers. The cells are called chondrocytes (ch) and empty

space within the cartilage is called lacunae. There are not a lot of fibers in the

hyaline cartilage as you can see by the slides; however, there is fibrous lining on

the outside which is called perichondrium . (100X and 400X)

http://www.austincc.edu/histologyhelp/tissues/to_hy_cart.html http://www.austincc.edu/histologyhelp/tissues/to_hy_cart.html

Elastic

Elastic cartilage is commonly found in the outer ear of an individual. The ear is very

bendable but still is able to hold its shape and that is because if this type of

cartilage. The elastic, or yellow, cartilage is also found in the eustachian tube, and

the epiglottis. The elastic and the hyaline cartilage are very similar histologically,

but the elastic cartilage has many fibers in the solid matrix. These fibers give the

cartilage the great elasticity and ability to move and bend and still retain its shape.

Fibro

While Hyaline and Fibro has some similarities, fibrocartilage looks different

because of the number of collagen fibers embedded in the matrix. From the slides

you can see the nuclei within the chondrocytes which are located in lacunae.

Fibrocartilage is found in the pubic symphysis, the anulus fibrosus of intervertebral

discs, menisci and the TMJ. The cartilage needs to be flexible as well but also very

strong and durable.

Bone Compact

In these slides, there are several structural units of bone tissue (osteons or

Haversian systems). Each osteon looks like a ring with a light spot in the center.

The center is a canal that carries a blood vessel and a nerve fiber. The outer ring,

which is also the darker part is made of bone matrix from cells. We are able to see

the layered structure of the bone in these slides. Moreover, the more purple and

pink slide shows compact bone that is decalcified. We wanted to show this

because there is a difference in appearance. The bone has been removed of its

calcium salts. To the right is some bone marrow as well. http://www2.sunysuffolk.edu/pickenc/Compact%20Bone%20Osteon

Spongy

With these slides and diagrams you can see how much space is in between the

bone. It is much less dense than compact bone and therefore, it takes up a lot of

surface space. This type of bone is typically found at the end of a large bone and

you can see this is one of the pictures. Spongy bone also contains a lot of red

bone marrow and blood vessels.

Fluid Blood Cells Erythrocytes

This is a slide showing erythrocytes, or commonly known as red blood cells. They

are the most numerous type of blood cells. Erythrocytes have the form of a

biconcave disk and are also narrow-waisted in profile. They contain the red

respiratory pigment called hemoglobin and are responsible for oxygen transport.

Red blood cells are formed in the bone marrow, liver, spleen, and lymph glands.

They survive for about 120 days and are then destroyed in the spleen and liver.

Leukocytes

Eosinophil: This slide shows several Eosinophil present. Eosinophil are members

of the granulocytic class of white blood cells that function primarily in fighting

infections of parasites and in allergic reactions. These cells generally are made up

of one to three percent of the total white blood cell count in a healthy individual.

Those who possess an unusually large number of eosinophils will have

eosinophilia getting rid of illnesses faster, however it leads to tissue damage. (x40)

Basophil: This slide contains a basophil (they have large dark granules which

usually occlude the view of the nucleus). Basophils are a type of white blood cell

produced in the bone marrow. They make up about 0.5% of the total number of

white blood cells. Basophils also protect the body, killing bacteria and parasites,

including external parasites like ticks. They are involved with causing allergies,

asthma, and other inflammatory reactions in the body. Basophils contain histamine

and heparin, a blood thinning substance produced by the body. (x400)

Neutrophil: This slide contains Neutrophils (the three big, dark, purple circles

toward the center of slide). Neutrophils are the most numerous type of leukocyte,

representing for 70% of all white blood cells. These are important in the

inflammatory process as Neutrophils are phagocytes and mediators of

inflammatory reactions. When the body is breached and foreign objects like

bacteria enter, neutrophils eat up the bacteria. A mature neutrophil is 12 to 15

microns in diameter and has a nucleus composed of 2 to 5 lobes. (x40)

Monocyte: This slide contains a monocyte cell: it is the purple cell seen in the

middle. The nucleus is folded, and a monocyte cell is the largest of the leukocyte

cells. It can also differentiate into a macrophage, meaning it can turn into a

macrophage. Monocytes compose 2% to 10% of all leukocytes in the human body.

They also help to serve many immune functions. If one has acute monoblastic

leukemia it would mean that there is a dominance of monoblast cells in their blood

marrow. Artist illustration, and x100 magnification)

Lymphocytre: These slides contains a lymphocyte cell in the middle (purple cell)

surrounded by red blood cells. Lymphocytes are the smallest cells of all the

leukocytes, and they are mostly characterized by their nuclei which take up almost

the whole cell. It is a subtype of a white blood cells. Lymphoma cancers can start

in immature lymphocytes, and when one does not have enough white blood cells

in their bloodstream, it means they, typically, cannot fight off the cancerous cells.

Macrophage: In this slide is a macrophage is too the right of the large cell. It is

another subtype of white blood cells, and is typically a large cell, in contrast to the

smallness of lymphocytes. They are incredibly important to the immune system as

they help destroy any foreign substances such as: cancer cells, cellular debris, etc;

essentially anything that is not healthy for the body (x100 magnification)

Cell Fragments Platelets

In this slide, the platelets are the smaller blue dots surrounded by red blood cells.

Platelets stop bleeding by clotting and clumping blood vessel injuries. You have

just cut your hand? Platelets to the rescue! While you may need to put a bandage

on it for a little while, the platelets will do the rest for you. They are typically about

20% the diameter of a red blood cell. The normal range of platelets in a healthy

Caucasian is 150,000 to 450,000 per cubic millimeter. That is a lot.

Cardiac

Cardiac muscle is striated, like skeletal muscle. Cardiac muscle cells usually have

a single (central) nucleus. The cells are often branched, and are tightly connected

by specialised junctions. The region where the ends of the cells are connected to

another cell is called an intercalated disc. The intercalated disc contains gap

junctions that allow the muscle cells to be electrically coupled, so they beat in

synchronization

NeurogliaCNS Astrocytes

Astrocytes are the most numerous and diverse neuroglial cells in the central

nervous system. While most neuroscientists think they know what an

astrocyte is, there is no uniform and unequivocal definition of an astrocyte.

Not all astrocytes are star-like cells, not all of them express the specific

marker glial fibrillary acidic protein (GFAP), not all contact brain capillaries.

Astrocytes are actually the cell population in the brain which are left over after

one would remove neurons, oligodendrocytes and microglial cells. Thus

astrocytes display a remarkable heterogeneity in their morphology and

function.

Oligodendrocytes

The major function of oligodendrocytes and Schwann cells is the formation of

myelin. Myelin acts as an insulator of axonal segments and is a prerequisite

for the high velocity of nerve conduction, of up to 200 m/second.

Ependymal

Ependymal tissue forms an epithelial layer lining the cerebral ventricles.

Functioning as a barrier between the brain parenchyma and cerebrospinal

fluid (CSF), they play a role in cerebral fluid balance, toxin metabolism, and

Microglia

Microglia represent the endogenous brain defence and immune system,

which is responsible for CNS protection against various types of pathogenic

factors. Microglial cells derive from progenitors that have migrated from the

periphery and are from mesodermal/ mesenchymal origin.

Peripheral Schwann

Schwann cells are the supporting cells of the PNS. Like oligodendrocytes

schwann cells wrap themselves around nerve axons, but the difference is

that a single schwann cell makes up a single segment of an axon's myelin

sheath. Oligodendrocytes on the other hand, wrap themselves around

numerous axons at once. In addition to creating the myelin sheaths of PNS

axons, Schwann cells also aid in cleaning up PNS debris and guide the

regrowth of PNS axons.

Satellite

Satellite glial cells are glial cells that cover the surface of nerve cell bodies in

sensory, sympathetic and parasympathetic ganglia. They are derived from

the neural crest of the embryo during development. They also supply

nutrients to the surrounding neurons and also have some structural function.

Satellite cells also act as protective, cushioning cells.

Stratified Squamous Keratinized

These slides show the stratified squamous keratinized epithelium and how it

covers the entire surface of the skin. To be able to find stratified squamous

keratinized epithelium, you need to look at the skin on areas on your body that do

not have hair. This tissue shown is from the palm of the hand. These cells are flat

and no longer alive, with the addition of no nucleus nor organelles. Instead that are

filled with keratin which is what makes our skin waterproof. The cells on the surface

are dead and are continually lost as well as continuously being replaced by

mitosis. They start out as cuboidal, then irregular, and finally become flat.

its layers are composed mainly of connective tissue and muscle. As you can see,

the nuclei are arranged in more than one layer and how the cells seem to be

separating from the surface of the tissue. The cells form coverings and linings and

is a process called sloughing. Stratified squamous nonkeratinized epithelium can

also has numerous goblet cells. At x100 magnification, the pseudostratified ciliated

epithelium tissue can be seen next to the lumen. The epithelium has a darker stain

than the underlying connective tissue. It’s located in the lines of the upper

respiratory tract, the epididymis, and part of the male urethra. Its functions are

secretion and movement of mucus by ciliary action. (x40,x100,x400)

looking noticing that the shape of the cells next to the lumen, the presence of

scalloping, and the fact that in the nucleus of the cells next to the lumen the

nucleolus can be seen. This tissue has features common to stratified cuboidal and

stratified squamous. This tissue is located in the lines in the urinary bladder,

ureter, and part of the urethra. Its functions are that it stretches readily and permits

distension of urinary organ by contained urine. (x40,x100,x400)
