Q

What is holocrine secretion?

A

Secretory product invades cells which then burst for product release; cells die in process and are replaced

Q

What are the two types of special apocrine glands?

A
  1. Ceruminous glands
  2. Mammary glands
17
Q

What are ceruminous glands?

A

Modified apocrine sweat glands

18
Q

What do ceruminous glands secrete?

A

Secrete waxy cerumen (ear wax) via merocrine (or eccrine) secretion

19
Q

What are mammary glands?

A

Modified apocrine sweat glands specialized for milk production

20
Q

What kind of secretion mechanism do mammary glands have?

A

True apocrine secretion mechanism

21
Q

What is a true apocrine secretion mechanism?

A

Secretory product is released with shedding of cytoplasm of cells; no cell death like merocrine secretion

22
Q

How is mammary glands regulated?

A

By interaction of sexual and pituitary hormones

23
Q

Which gland is acne found?

A

In the sebaceous glands

24
Q

What is acne?

A

Inflammation of sebaceous glands and follicles

25
Q

How does inflammation in acne occur?

A

Results from blockage of ducts and bacterial infection of glands

26
Q

When does acne usually occur?

A

At onset of puberty (glands increase in size and sebum secretion increases in response to sex hormones)
