A

colonocytes

17
Q

Describe the lamina propria of the mucosa of the colon.

A

typical and has intestinal glands (crypts)

18
Q

Describe the muscularis mucosae of the colon.

A

typical

19
Q

What does the mucosa of the colon lack?

Describe the submucosa of the colon.

A

typical

21
Q

What kind of pattern does the muscularis externa of the colon have?

A

non-normal pattern

outer longitudinal muscle is gathered into bands called teniae coli and is discontinuous

22
Q

A

transverse and sigmoid colon

store fecal material

26
Q

What is the surface epithelium of the rectum?

A

simple columnar

27
Q

What are some notable features of the rectum?

A

significant luminal wall folds exist called transverse rectal folds
no teniae coli in muscularis externa (longitudinal is more complete)
luminal wall covering includes adventitia

28
Q

What is similar to the colon and rectum?

A

straight intestinal glands with goblet cells

29
Q

What is the surface epithlium of the anal canal?

A

transition from simple columnar to stratified squamous

30
Q

Where do the anal glands extend to?

A

submucousa

31
Q

What is the function of the anal gland?

A

lubricate lumen

32
Q

Where are the circumanal glands?

A

skin surrounding anus

33
Q

What do the mucosa and submucosa of the anus contain?

A

longitudinal folds to create anal columns

34
Q

What happens to the muscularis mucosa?

A

it disappears into the anal canal

35
Q

What is the internal anal canal?

A

a thick circular layer of smooth muscle within the muscularis externa

36
Q

What is the external anal canal?

A

a striated muscle from the pelvic floor, voluntary muscle

37
