Salivary & Pancreas

Question 0

Compound acinar examples?

Answer 0

Parotid, pancreas

Question 1

Compound tubuluacinar examples?

Answer 1

Submandibular, sublingual

Question 2

Striated duct features?

Answer 2

• lined by high cuboidal cells, basal striations that parallel the longitudinal axis of the cell
• striations are due to deep infoldings of the basal plasma membrane, which compartmentalize mitochondria
• Fx.: Reabsorption of Na+, excretion of K+ & Bicarb into saliva

Question 3

Parotid gland features?

Answer 3

• Granules rich in proteins, including proline-rich enzymes
• Serous gland
• Myopithelial cells present
• longest intercalated discs

Question 4

Submandibular gland features?

Answer 4

• mixed gland
• demilunes
• compound tubuloacinar

Question 5

Sublingual glands features?

Answer 5

• mucous gland
• serous demilune
• tubular and tubuloacinar glands

Question 6

Saliva features?

Answer 6

• Hypotonic solution unless stimulated sympathetically

- Most is secreted by submandibular glands (70%)

Question 7

Comparison b/w pancreatic acini & parotid gland acini.

Answer 7

Parotid salivary gland

• myoepithelial cells
• striated ducts
• serous acini
• no centroacinar cells
• no islets of Langerhans

Pancreas exocrine

• no myoepithelial
• no striated ducts
• serous acini
• centroacinar cells (squamous-to-cuboidal epithelial cells)
• iselts of Langerhans
