29
Characteristics of epithelial tissue
Cellularity, polarity, attachment, avascularity, sheets or layers, & regeneration
30
Simple squamous epithelium
Characteristics: Cells are thin, flat, & irregular shapes Location: Inner surfaces of circulatory system
31
Stratified squamous epithelium
Characteristics: Irregularly shaped cells in a series of layers Location: Surface of skin, lining of oral cavity, throat, esophagus, rectum, vagina & anus
32
Cuboidal epithelium
Characteristics: Look like little boxes & provide limited protection Location: Found where secretion or absorption happen, ex. Kidney tublues
33
Stratified cuboidal epithelia
Characteristics: Rare Location: Found lining the ducts of sweat glands & mammary glands
34
Columnar epithelia
Characteristics: Look like rectangles or columns Location: Found in areas where absorption or secretion occurs, ex. lining of stomach
35
Stratified columnar epithelia
Characteristics: Rare (if it has more than two layers, only the superficial cells are columnar, the cells below are squamous) Location: Occur in the pharynx, urethra, and anus
36
Pseudostratified epithelia
Characteristics: Located at varying distances from the surface Location: Nasal cavity, trachea, bronchi and portions of the male reproductive tract

40
Osteocytes
Mature Bone Cells that maintain the protein & mineral content of the matrix.
41
Osteoblasts
Immature Bone Making Cells that are heavily involved in the making new bone.
42
Osteoprogenitor Cell
Bone Stem Cells that differentiate to form new osteoblasts & are heavily involved in repair of bones after a break.
43
Osteoclasts
Multinucleated Bone Breaking Cells that secrete acids that dissolve bones to release stored calcium & phosphate ions into the blood.
44
Osteon
The functional unit of mature compact bone.
45
