submucosa
Which sublayer of the mucosa will typically possess smaller blood vessels and looser connective tissue?
Lamina propria
What does it mean if the ME has a “normal pattern”
inner circular
outter longitudinal

serosa
In general what does parasymp activation to the G.I. do?
Stimulates peristalsis, inhibits sphincters, activates secretion
In general what does symp. activation do to the G.I.?
inhibit peristalsis, contract sphincters, limit blood flow to gut

Which layer of muscle within the ME of stomach is not always present
oblique
Name surface epithelium of stomach
simple columnar
What are lacteals
lymphatic capillaries
Where are paneth cells found? What do they do?
base of crypts; produce lysozyme
Where are Brunner’s glands found? What do they do?
submucosa of Duodenum; neutralize incoming chyme
Where are lacteals found?
lamina propria of small intestinal vili
Why are lacteals important
absorption of lipids
What is unique about the submucosa of ileum
contains peyer’s patches

mucosa
Does the ME of the small intestine have a normal pattern?
yes
Which type of covering does the duodenum have next to (outside) its ME
some serosa but mainly adventitia

simple columnar
Name surface epithelium of colon
simple columnar
Does the appendix have villi?
no
Does the colon have villi
no
What layer is found covering the ME of the transverse colon?
serosa (transverse and sigmoid = serosa) (Ascending and Descending = adventitia)
Does ME of colon have normal pattern
No - outer longitudinal muscle gathers into bands called teniae coli
