Lymph Lymph

1. Lymph nodules are unencapsulated lymphoid tissue located in several

organs of the digestive and respiratory tracts, and all organs of the lymphatic

system. They are composer of densely packed lymphocytes (mainly B-

lymphocytes) that differentiate into plasma cells after appropriate antigenic

stimulation. Secondary lymph nodules exhibit a pale staining germinal

center, indicating that an antibody response to an antigen is occurring.

Primary lymph nodules have not been activated, therefore, lack germinal

centers. Peyer's patches are aggregates of unencapsulated nodules found in

the lamina propria of the ileum. 2. Lymph nodes are spherical or kidney-

shaped organs that are distributed throughout the body. The node is

enclosed by a connective tissue capsule from which large connective tissue

trabeculae arise and subdivide the underlying parenchyma. Each lymph

Muscle Skeletal

  1. This skeletal muscle cross section is preserved with a collagen stain to

bring out the perimysium between the fascicles.  Each muscle is composed

of thousands of fibers (E), each with a covering of loose connective

tissue—endomysium (B). The fibers are organized in parallel bundles called

fascicles (D). Each fascicle is surrounded by a perimysium sheath (A); the

presence of collagen bundles suggests dense connective tissue. Multiple

fascicles are encased in a dense connective tissue—epimysium, which

covers the entire muscle organ. Blood vessels, like the one shown at (C),

and nerve fibers penetrate to the endomysium to supply the muscle fibers. 

3. Longitudinal section of skeletal muscle: The individual muscle fiber (C)

originates from a fused series (syncytium) of myoblasts surrounded by a

common sarcolemma. Because of this, multiple nuclei (B) are found within

Central

4 typesEpendymal

1. Spinal cord central canal (H&E stain). The central canal of the spinal cord

is lined by ependymal cells which have cilia (arrows) that project into the

lumen of the central canal. 2. The ventricles of the brain and the central

canal of the spinal cord are lined with ependymal cells. The cells are often

cilated and form a simple cuboidal or low columnar epithelium. The lack of

tight junctions between ependymal cells allows a free exchange between

cerebrospinal fluid and nervous tissue. 3. The ependymal cells that make up

the choroidal epithelium 4. Cells that line the Ventricle of the brain and the

central canal of the spinal cord ependymal cells are ciliated cuboidal glial

cells

astrocytes

1. This micrograph is of a section of brain stained using a Holzer stain,

demonstrates the astrocytes with their many processes, giving them a star-

shaped appearance (arrows). 2. This preparation allows visualization of even

finer astrocytic processes. 3. This is an example of an anaplastic

astrocytoma. 4.Cell bodies of astrocytes are among the largest for the glia,

but only overlap the lower end for size of neurons. 5. Astrocytes, known for

the many processes attached to their cell body, provide structural support

and their processes often have 'end feet' that abut the basal lamina around

the capillary endothelium or line the exterior surface of the CNS, where they

contribute to the pial-glial external limiting membrane.

Oligodendrocytes

1. Cultivated oligodendrocytes (in green) and an intracellular marker (in red).

) Signaling pathways that modulate oligodendrocyte progenitor cell migration

in the developing brain. 2) Signaling mechanisms that regulate

oligodendrocyte differentiation and myelination.

3) Identification of small molecules that enhance oligodendrocyte

differentiation. This drug discovery project has identified compounds that

enhance oligodendrocyte differentiation in cultured cells, and that enhance

remyelination in demyelinated tissue. 4) differentiation can be imaged in

manipulated experimentally.

microglia

1. This is a high-power view of two microglia stained with a silver method.

This is what Rio-Hortega used when he first described this cell type in 1919.

2. Microglia are the smallest of the glial cells. Some act as phagocytes

cleaning up CNS debris. Most serve as representatives of the immune

system in the brain. Microglia protect the brain from invading

microorganisms and are thought to be similar in nature to microphages in

the blood system. 3. They have spindley processes eminating from the

central cell body. On H&E stain, all one would be able to see is a small rod-

shaped nucleu 4. This H&E stained section shows a microglial nodule in

a brain of a patient who died with AIDS. It is a common finding in patient with

AIDS encephalopathy. Such nodules probably form in response to viral

antigens: HIV itself and/or CMV.

Epithelial Simple Squamous

1. Simple squamous epithelium is made up of one layer of flat cells. This

picture shows the lining of an artery. 3. These cells come off the stratified

squamous epithelial tissue on the inner surface of the cheek. These cells

show the irregular, flat shape characteristic of typical "squamous cells." The

nucleus (A) is centrally located, the cell membrane (C) is very thin, and the

cell is filled with cytoplasm (B). 4. A) line the walls of blood vessels; at the

right it makes up the lung alveoli (A) wall.In both cases the cells are very

thin.

Cuboidal

1. Simple cuboidal epithelium is made up of one layer of cube-shaped cells.

These cells frequently make up the tubes of your body. 2. This kidney

tubules cut such that they appear as a ring of cell around empty space. The

cuboidal cell (A): lines these tubules are as wide as they are tall as they are

deep and (B): are the nudlei are easily observed. FUNCTIONS: secretion,

excretion and absorption. 4. This tissue lines the tubules of the kidney. You

can see the lumen (open area) and the single layer of cuboidal cells that

enclose a tubule. The cells are cuboidal in shape with the nucleus in the

center.

membrane, connective tissue, goblet cell and the lumen of intestine(free

edge, apical surface) 3. This tissue is characteristic of most of the GI tract.

In this section of the large intestine, the lumen is on the right. Notice the

long, skinny cells, with nuclei at their base, lined up like dominoes in single

file. The large clear spaces are goblet cells, which produce mucous for

lubrication of the intestinal lining. 4. This is an oil-immersion (1000 X) view of

a section of the large intestine. Individual columnar cells are clearly seen. In

addition, the goblet cells are especially prominent. At this power, it is easier

to see the microvilli of the brush border.

Stratified Squamous Keratinized

1. The cells on the surface of stratified squamous keratinized epithelium are

very flat. Not only are they flat, but they are no longer alive. They have no

nucleus or organelles. They are filled with a protein called keratin, which is

what makes our skin waterproof. The arrow at the top of the image is

pointing to a keratinized cell that has partially separated from the rest of the

skin. These dead cells are continually lost from the surface of the skin, and

are replaced by new cells from the layers below. 2. This high magnification

image of the section from a thin skin shows the keratinized stratified

squamous epithelium that makes up the epidermis and the underlying

dermis of dense, irregular collagenous connective tissue. The portion of this

epithelium closest to the dermis is composed of a living cells, which have

with nuclei and basophilic cytoplasm. The outer portion is composed of

image is labeled with free edge, basement membrane and connective tissue.

3. All the squamous cell out to the surface have nuclei 4. Note that the

cervical glands are wide, numerous, and branching. The glands are lined by

simple columnar epithelium. The cervical canal is lined also by simple

columnar epithelium. This epithelium abruptly changes to nonkeratinized

stratified squamous epithelium near the external os. Note on the vaginal side

of the slide there is an absence of glands but many veins.

Cuboidal

1. Cross-sectional view through a duct of a sweat gland illustrating stratified

cuboidal epithelium. 2. Stratified cuboidal epithelium lines the ducts of sweat

glands. 3. In which, more than one layer of cuboidal cells are found arranged

on a basement membrane. It occurs in some parts of the reproductive

system, ducts of sweat glands and in the lining of the pharynx. 4. Two

adjacent seminiferous tubules, separated by connective tissue (CT), are

present in the image. The germinal epithelium is composed of stratified

cuboidal cells in various stages of spermatogenesis. Spermatozoa (Sz) are

vaguely visible in the tubule lumens.

Columnar

1. Stratified Columnar epithelium is rare. One place you can find it is in the

largest ducts of salivary glands. The basal layer of cells are cuboidal cells

and the layer nearest the apical surface includes columnar cells. The large

droplets are mucus, in Goblet cells. 2. A large submaxillary gland is labeled

with yellow arrow. 3.A double layer of stratified columnar cells enclose the

lumen of a salivary duct in the submandibular gland. Even though the

plasma membranes of the cells are obscure, the cells can be identified as

being columnar because the nuclei are located at the base of the cells. The

duct is surrounded by connective tissue (CT) in which darkly stained

fibroblast (Fb) nuclei can be seen. 4, This image is labeled with Lumen and

1. Transitional Epithelial cells can slide by one another allowing the

epithelium to get thinner (as in a full bladder) without losing the ability to

form a strong layer. 2. Two diagnostic characteristics are: luminal cells -are

sometimes binucleate and "balloon" out into the lumen giving an uneven

appearance to the luminal surface.3. This image is labeled with connective

tissue, blood vessel and lumen 4.a collapsed layers of the transitional cells,

1. Pseudostratified columnar epithelium is made up of one layer of columnar

cells which frequently look like multiple layers. 2. (A)This tissue all begin at

the basement membrane, only a few reach the surface. (B): cilia are easily

seen on the surface. (C): the nuclei appear at various levels giving the tissue

a stratified appearance. FUNCTION: Secretion and movement of mucus by
