29
What is the function of microvilli in non-ciliated simple columnar epithelium?
Increases surface area for absorption ## Footnote Found in the intestine.
30
What type of epithelium provides protection and is keratinized?
Keratinized stratified squamous epithelium ## Footnote Located in the epidermis.
31
What is the location of nonkeratinized stratified squamous epithelium?
Oral cavity and inner lining of the vagina ## Footnote All cells are alive.
32
What is the function of stratified cuboidal and columnar epithelium?
Protection ## Footnote Located in big glands and the male urethra.
33
What characterizes pseudostratified columnar epithelium?
Looks stratified but every cell attaches to the basement membrane ## Footnote Contains cilia and goblet cells, secretes mucin.
34
What is the composition of mucus?
Mucin + H2O = mucus ## Footnote Mucin is secreted by pseudostratified columnar epithelium.
35
What type of epithelium can stretch and is found inside the bladder?
Transitional epithelium ## Footnote Can change from many layers to few layers.
36
What are the functions of connective tissue?
binding of structures
37
What are the that make up connective tissue?
Cells, extracellular matrix, protein fibers, ground substance.
38
What are the states of ground substance in connective tissue?
Liquid, gel, solid.
39
What are the types of connective tissue?
Connective tissue proper, loose, dense.
40
What characterizes loose connective tissue?
Fewer fibers, more ground substance.
41
What characterizes dense connective tissue?
More fibers, less ground substance.
42
What are the cells of connective tissue proper?
Fibroblasts, adipocytes, fixed macrophages, mesenchymal cells.
43
What do fibroblasts do?
Build fibers.
44
What are adipocytes?
Fat cells.
45
What do fixed macrophages do?
Eat damaged tissue.
46
What are mesenchymal cells?
"Left over" cells that divide and repair.
47
What are wandering cells in connective tissue?
mast cells, plasma cells, free macrophages, and other leukocytes.
48

Collagen, elastic, reticular.
50
What are the characteristics of collagen fibers?
Tough, not flexible, found in tendons and ligaments, most protein, pink in slides.
51
What are the characteristics of elastic fibers?
Stretchy, but not as strong, stain black or purple in slides.
52
What are the characteristics of reticular fibers?
Net-like, stain black or purple in slides.

65
What is supportive connective tissue?
Supportive connective tissue includes cartilage, which provides support and protection.
66
What are the general components of cartilage?
Cartilage is composed of cells, chondoblasts that develop into chondrocytes, a matrix, ground substance, and fibers.
67
What is a characteristic of cartilage repair?
Cartilage has a hard time repairing due to low blood supply.
68

Hyaline cartilage contains chondrocytes, appears smooth with no visible fibers, and is found in the fetal skeleton, nose, rib cage, and lining joint surfaces.
69
What is fibrocartilage?
Fibrocartilage has visible fibers, is stronger due to larger fibers, and is located in intervertebral discs and the pubic symphysis.
70
What is elastic cartilage?
Elastic cartilage contains chondrocytes, ground substance, and elastic fibers, and is characterized by skinny purple fibers.
