22
Q

What is the function of myoepithelial cells?

A

To assist secretion

23

A

Trapezoid shaped

25
Q

What are examples of serous glands?

A

Pancreas, parotid gland, chief cells in stomach

26
Q

What is the appearance of the nucleus of serous glands?

A

Round and noticeable

27
Q

What is the staining characteristic of serous glands?

A

Tend to pick up stains well

28
Q

Goblet cells, mucous cells in stomach, and the minor salivary glands in tongue and palate are examples of what type of exocrine gland?

A

Mucus glands

29
Q

How do mucus gland cells typically stain?

A

Light

30
Q

What is the appearance of the nucleus of mucus glands?

A

31
Q

What is the name of glands that produce serous and mucus?

A

Mixed glands

32
Q

What are examples of mixed glands?

A

33
Q

Serous demilunes are present among what type of exocrine gland?

A

Mixed

34
Q

What three things regulate exocrine secretion?

A

Myoepithelial cells, hormones, blood supply

35
Q

What effect does an increase of blood supply have on exocrine glands?

A

Increased oxygen and increased secretion

36
Q

What effect does a decreased blood supply have on exocrine glands?

A

Decreased oxygen and decreased secretion

37
Q

In endocrine secretion, what is the secretory product generally called?

A

A hormone

38
Q

What type of secretion involves the release of secretory product into connective tissue for vascular dispersal to target organs and tissues?

A

Endocrine secretion

39
Q

What type of endocrine secretion involves the signaling cell being so close to the target cell that the hormone does not enter the blood?

A

Paracrine secretion

40
Q

In what type of endocrine secretion is the signaling cell its own target?

A

Autocrine secretion

41
Q

What two things regulate endocrine secretion?

A

Hormonal feedback loops (positive and negative), autonomic nervous system
