Histology
Simple squamous epithelium
Single layer of flattened cells.
Simple cuboidal epithelium
Single layer of cubelike cells.
Simple columnar epithelium
Single layer of tall cells With tall oval nuclei.
Pseudo Stratified columnar epithelium
Single layer of cells of differing heights, nuclei at different levels.
Stratified squamous epithelium
Thick membrane composed of several layers. Basal layers are cuboidal or columnar with flattened surface layers.
Stratified cuboidal epithelium
Generally two layers of cube like cells.
Stratified columnar epithelium
Several cell layers. Basal cells usually cuboidal with superficial columnar cells.
Transitional epithelium
Resembles both stratified squamous and stratified cuboidal. Different shapes based on organ stretch.
Connective tissue proper: loose connective tissue, adipose.
Gel like matrix but scarce. Tightly packed adipocytes, or fat cells, have nucleus pushed to the side by large fat droplets.
Cartilage: Hyaline
Amorphous but firm matrix; collagen fibers form an imperceptible network; chondroblasts produce the matrix and, when mature, lie in lacunae.
Cartilage: elastic
Similar to hyaline, but more elastic fibers in matrix.
Cartilage: fibrocartilage
Matrix similar to but less firm than matrix in hyaline cartilage, thick collagen fibers predominate.
Bones (osseous tissue)
Hard, calcified matrix containing many collagen fibers; osteocytes lie in lacunae. Very well vascularized.
Blood
Red and white blood cells in a fluid matrix.
Nervous tissue
Neurons are branching cells; cell processes that may be quite long extend from the nucleus-containing cell body; also contributing to nervous tissue are non-excitable supporting cells.
Skeletal muscle
Long cylindrical, multinucleate cells, obvious striations.
Cardiac muscle
Branching striated, generally uninicleated cells that interdigitate at specialized junctions called intercalated discs.
Smooth muscle
Spindle shaped cells with central nuclei; no striations; cells arranged closely to form sheets.
Neuron
