Proximal GIT II - Salivary Glands

Question 1

types of salivary glands (3)

Answer 1

Parotid= anterior to ear, almost exclusively serous acini (in face, small duct // mucus not viable) 
SubMandibular= under mandible, 80% serous
SubLingual= under tongue, almost all mucus acini

Question 2

when is it salivary or pancreas glands

Answer 2

solid organ divided into lobes

1. just serous acini= pancreatic islets > pancreas, none > parotid
2. mixed serous and mucus= mostly serous > Submandi, mostly mucus > sublingual

Question 3

what colour is serous acini usually

Answer 3

bright pink

Question 4

when does parotid gland + duct go to

Answer 4

oral cavity to parotid papilla

Question 5

diff b/w parotid and submandibular gland

Answer 5

o Mucus acini (pale staining)
o Mucus vs serous cells in acinus
• Colour > Stain different, mucus= pale + serous = darker
• Nucleus > central in serous, peripheral (on basement) in mucus
o Duct vs serous acini
• Duct= lumen

Question 6

how to tell if sublingual gland

Answer 6

• Pale as mostly mucus gland

Question 7

serous vs mucus

Answer 7

o Mucus = pale, secrete mucus + filled cells, found in sublingual in high proportion and submodular in 20%, peripheral nuclei

Question 8

• Intercalated Vs striated

Answer 8

o i= round large nuclear, no foldings of basement membrane, thinner membrane
