Simple squamous epithelium
Single layer of flattened cells. found on edges
knowt flashcard image
Simple cuboidal epithelium
Single layer of cubelike cells.
knowt flashcard image
Simple columnar epithelium
Single layer of tall cells With tall oval nuclei.
knowt flashcard image
Pseudo Stratified columnar epithelium
Single layer of cells of differing heights, nuclei at different levels. Cilia on top
knowt flashcard image
Stratified squamous epithelium
Thick membrane composed of several layers. Basal layers are cuboidal or columnar with flattened surface layers.
knowt flashcard image
Stratified cuboidal epithelium
Generally two layers of cube like cells. Found in glands.
knowt flashcard image
Stratified columnar epithelium
Several cell layers. Basal cells usually cuboidal with superficial columnar cells.
knowt flashcard image
Transitional epithelium
Resembles both stratified squamous and stratified cuboidal. Different shapes based on organ stretch. Found in the urinary system.

Connective tissue: adipose.
Gel like matrix but scarce. Tightly packed adipocytes, or fat cells, have nucleus pushed to the side by large fat droplets.
knowt flashcard image
Cartilage: Hyaline
Amorphous but firm matrix; collagen fibers form an imperceptible network; chondroblasts produce the matrix and, when mature, lie in lacunae.
knowt flashcard image
Cartilage: elastic
Similar to hyaline, but more elastic fibers in matrix.
knowt flashcard image
Cartilage: fibrocartilage
Matrix similar to but less firm than matrix in hyaline cartilage, thick collagen fibers predominate.
knowt flashcard image
Bones (osseous tissue)
Hard, calcified matrix containing many collagen fibers; osteocytes lie in lacunae. Very well vascularized.
knowt flashcard image
Red and white blood cells in a fluid matrix.
knowt flashcard image
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.
knowt flashcard image
Skeletal muscle
Long cylindrical, multinucleate cells, obvious striations.
knowt flashcard image
Cardiac muscle
Branching striated, generally cells with one nucleus each that connect at specialized junctions called intercalated discs.
knowt flashcard image
Smooth muscle
Spindle shaped cells with central nuclei; no striations; cells arranged closely to form sheets. Lines digestive system.
knowt flashcard image
a nerve cell; the basic building block of the nervous system
knowt flashcard image
Connective tissue: Areolar
Function: Wraps and cushions organs, Found around organs, surrounds capillaries
knowt flashcard image
Connective tissue: reticular
Thin collagen fibers in a 3d network. Found in liver and spleen
knowt flashcard image
Dense connective tissue: Regular
Durable, but poor blood supply and not stretchy. Found in tendons and ligaments
knowt flashcard image
Dense connective tissue: Irregular
Thicker, interwoven, and more randomly organized tissue found in the dermis
knowt flashcard image
Dense connective tissue, elastic
Containing a high proportion of elastic fibers. Found in tissues that need to stretch, such as blood vessels.
