histopathology
four types of tissue
epithelial
connective
muscular
nervous
-the type of tissue forms into membrane or gland
epithelial tissues
classified by the outermost cell layer or the number of cell layers
epithelial tissues
flattened cells with a polygonal shape when viewed from above
squamos
mesentry, pleura, pericardium, peritoneum, mesothelium, inner cheek cells
squamos
cells with more or less equal height and width
cuboidal
tubules in the kidney, germinal epithelium of ovary, thyroid follicles
cuboidal
cells with greater height than width
columnar
only one layer
simple
more than one cell layer
stratified
one layer of cells but appears like two or three layers due to different nuclear layers and cell heights
pseudostratified
cell layers vary from two to six
transitional
consist of cell matrix (connective tissues fibers, ground subtances, tissue fluid)
connective tissues
main functions are to bind, anchor, and provide support for various body parts and organs
connective tissues
most widespread of all connective tissues
loose ct
collagen, elastic fibers, reticular, adipose
loose ct
dermis of the skin
Dense ct
tendons and ligaments
dense ct
____: supporting tissue of the embryos; articular surfaces of the bones; appear clear and glass-like
hyaline
___: found in areas where support and flexibility are required
elastic
____: found in parts where tough support is required; pubic symphysis; atlas; ankle
