Connective Fibrous Loose Areolar
This slide shows loose (areolar) connective tissue which is used extensively throughout the body for fastening down the skin
membranes vessels and nerves as well as binding muscles and other tissues together The tissue consist of an extensive network of
fibers secreted by cells called fibroblasts The most numerous of these fibers are the thicker lightly-staining collagenous fibers
Thinner dark-staining elastic fibers composed of the protein elastin can also be seen

Reticular
Reticular connective tissue is named for the reticular fibers which are the main structural part of the tissue The cells that make the reticular fibers are fibroblasts called reticular cells Reticular
connective tissue forms a scaffolding for other cells in several organs such as lymph nodes and bone marrow You will never see
reticular connective tissue alone--there will always be other cells scattered among the reticular cells and reticular fibers

Dense Regular
Dense connective tissue is characterized by an abundance of fibres with fewer cells as compared to the loose connective tissue It is
also called fibrous or collagenous connective tissue because of the abundance of collagen (collagenous) fibres Little intercellular substance is present Furthermore in this tissue type the fibres
are organized in a regular parallel pattern (Figure 12) Hence the name ndash dense regular (fibrous or collagenous) connective tissue

Neutrophil
Neutrophils are a type of granulocytic white blood cell They are distinguished by their lobed nucleus and the presence of fine purple granules in their cytoplasm (under HampE or other Romanovsky stains)
Neutrophils are phagocytotic cells capable of ingesting and killing bacteria and other pathogens They are the most numerous white blood cells with 20 - 75 x 10^9 neutrophils L blood of a healthy
individual

Muscle Skeletal
Skeletal muscles form the flesh sometimes referred to as the red meat of an animals body They are attached to and result in the movement of the bones of the skeleton A typical skeletal muscle
cell is a highly modified giant multi-nucleate cell (fibre) Each fibre is cylindrical in shape with blunt rounded ends The flattened nuclei are located mainly at the periphery of the cell just inside the sarcolemma The cross-striped (or striated) appearance of light and dark banding results from the arrangement of myofibrils small
protein contractile units embedded in the sarcoplasm

Smooth muscle is abundant throughout the internal organs of the body especially in regions such as the digestive tract As its
contraction is not under conscious nervous control it is referred to as involuntary muscle Smooth muscle fibres are spindle-shaped
structures with a prominent centrally located nucleus In comparison with skeletal muscle fibres they are much shorter in
length and they do not exhibit striations The cells occur as individual fibres within organs or as groups of fibres closely
interlaced in sheets or bands

Cardiac
Cardiac muscle is a highly specialized tissue restricted to the wall of the heart It is also an involuntary type of muscle as its
contraction is not consciously controlled Unlike smooth or striated fibres cardiac fibres tend to form long chains of cells which branch and intertwine This arrangement results in the peculiar wringing
action of the heart The junction of one cell with another in a particular chain is known as an intercalated disc and appears as a heavy dark line running across the fibre Each cell has a somewhat cylindrical shape with one centrally-located oval nucleus Cross-striations are apparent but they are not as regular nor as prominent
as those of skeletal muscle

OligodendrocyteOligodendrocytes resemble astrocytes but are smaller and contain
fewer processes They form and maintain myelin sheath around axons in the CNS
An oligodendrocyte the myelinating glial cell of the CNS

Epithelial Simple Squamous
Simple Squamous Epithelium consists of a single layer of flattened cells Allows passage of materials by diffusion and filtration in sites
where protection is not important Secretes lubricating substances in serosae

which the cells in the apical layer are cube-shaped They function as protection and has limited secretion and absorption
