Q

Glandular epithelia’s types of secretions:

A

Serous glands-watery secretions
Mucous glands-secrete mucins
Mixed exocrine glands-both serous and mucous

17
Q

In this type of secretion, the product is released from secretory vesicles at the apical surface of the gland cell by exocytosis

A

Merocrine secretion

18
Q

This type of secretion involves the loss of the apical cytoplasm, inclusions, secretory vesicles, and other cytoplasmic components. These are all shed in the process.

A

Apocrine secretion

19
Q

The gland cell then grows and repairs itself before it releases additional secretions

A

Apocrine secretion

20
Q

Occurs as superficial gland cells burts

A

Holocrine secretion

21
Q

Continuedsecretion involving the replacement of these cells through the mitotic divisions of underlying stem cells

A

Holocrine secretion

22
Q

These are the only unicellular exocrine glands

A

Mucous (aka goblet) cells

23
Q

Scattered among epithelia and can be found in intestinal lining

A

Mucous (aka goblet) cells

24
Q

Unicellular glands

A

Mucous (aka goblet) cells

25
Q

Glandular epithelia’s structure is comprised of _________ __________________ which are made of __________ _________

A

Unicellular glands

26
Q

Multicellular glands Structure of the duct can be:

A
  • Simple (undivided)

* Compound (divided)

27
Q

Multicellular glands Shape of secretory portion of the gland can be:

A
