simple squamous, stratified squamous (keratinized and non-keratinized), simple cuboidal, stratified cuboidal, simple columnar, stratified columnar, pseudo stratified ciliated columnar, transitional

2
Q

locations of simple squamous cells

A

mesothelia (ventral body cavities), endothelia (lining heart, blood vessels and lymphatic vessels), lungs, kidneys (glomerular capillary)

3
Q

locations of stratified squamous (keratinized)

A

epidermis of skin

4
Q

locations of stratified squamous (non-keratinized)

A

lining of mouth, throat, esophagus, rectum, anus, vagina

5
Q

locations of simple cuboidal

A

ducts of glands, kidney tubules

6
Q

locations of stratified cuboidal

A

ducts of some glands (sweat glands)

7
Q

locations of simple columnar

A

nonciliated: stomach, intestines
ciliated: Fallopian tubes, uterus

8
Q

locations of stratified columnar

A

pharynx, anus, urethra

9
Q

locations of pseudostratified ciliated columnar

A

upper respiratory system (nasal cavity, trachea, bronchi)

10
Q

transitional

A

urinary bladder, ureters, urethra

11
Q

simple squamous function+description

A
  • single layer of flat cells that resembles a tiled floor when viewed from the apical surface; centrally located nucleus that is flattened and oval or spherical in shape
  • present at sites where the processes of filtration, diffusion, and secretion occur. not found in body areas subject to wear and tear.
12
Q

simple cuboidal function+description

A
  • single layer of cube-shaped cells; round, centrally located nucleus.
  • secretion and absorption
13
Q

non-ciliated simple columnar

A
  • single layer of non-ciliated column-like cells with oval nucleus near base of the cell, contains two types: columnar with microvilli at their apical surface and goblet cells
  • secretion and absorption, secreted mucus serves as a lubricant for the linings of tracts
14
Q

goblet cells

A

a type of simple columnar, modified and secrete mucus at their apical surfaces. Provide mucus for digestive
