Lecture 9 Learning Objectives

Question 1

Parenchyma

Answer 1

Components of the gland derived from epithelium

Question 2

Stroma

Answer 2

Connective capsule surrounding the entire gland as well as the connective tissue partitions separating the lobules and lobes (septa)

Question 3

Lobes

Answer 3

Subdivision of a compound gland separated from adjacent lobes by septae

Question 4

Lobules

Answer 4

Subdivision of lobe, separated by delicate septae

Each lobule is equivalent of simple, branched gland

Question 5

Acini

Answer 5

Secretory components of lobule
May be serous, mucous or sero-mucous
Basement membrane covers outer surface of the acinus
Myoepithelial cells

Question 6

Intercalated ducts

Answer 6

Drain the secretory acini
Lined by simple squamous to low cuboidal epithelium
Bicarbonate/ chloride exchange

Question 7

Striated Ducts

Answer 7

Lined with cuboidal epithelium transitioning to low cuboidal epithelium
Actively reabsorb Na ions

Question 8

Parotid glands

Answer 8

Only Serous acini

Question 9

Submandibular glands

Answer 9

Mixed glands

Demilunes around mucous acini

Question 10

Sublinguil glands

Answer 10

Mixed – mucous acini are predominant
