23
Q

What causes the acidophilic striations in the intralobular striated ducts? What do these cause?

A

Mitochondria

Nuclei are pushed to the apical domain (toward duct)

24
Q

What type of gland is the submandibular gland? Why?

A

mixed, there are both serous cells and mucus cells

25
Q

How do mucus cells appear in the submandibular gland?

A

Lightly stained, with nuclei in the basal domain

26
Q

How do serous cells appear in the submandibular gland?

A

Darkly stained, acidophilic

27
Q

Which are found in greater numbers within the submandibular gland: serous cells or mucus cells?

A

Serous cells

28
Q

What are serous demilunes? What are they produced by?

A

“Caps” produced by serous cells over the mucus cells. Found in submandibular glands. THESE ARE ARTIFACTS of tissue processing.

29
Q

What is the classification of the sublingular gland? How is it different from the submandibular gland?

A

It is a compound tubulo alveolar gland, but has mucus cells predominating

30
Q

What type of ducts are found in the sublingual gland?

A

Intralobular striated duct

31
Q

What type of gland is the pancreas?

A

Compound acinar gland

32
Q

Intercalated ducts are of what type?

A

Intralobular

33
Q

What are centroacinar cells?

A

Cells that make up the intraacinar segment of the intercalated duct

34
Q

What does the reticular layer of the dermis contain?

A

Dense irregular CT and elastic fibers

35
Q

How many layers of cells are in the stratum basale?

A

Single

36
Q

How many layers of cells are in the stratum spinosum?

A

Several

37
Q

What is the basophilic chemical in the statum granulosum?

A

Keratohyaline

38
Q

How many layers of cells are in the stratum granulosum?

A

Few

39
Q

Where in the skin are Meissner’s corpusles seen?

A

Papillary part of the dermis

40
Q

What is the classification of sebaceous glands?

A

Simple alveolar gland

41
Q

What type of exocrine gland cell has avaculated cytoplasm?

A

Sebaceous cells

42
Q

Do all hair follice have sebaceous glands? Is the reverse true?

A

All hair follice have sebaceous glands, but the reverse is not true

43
Q

What is released when the erector pilli muscle contract?

A

sebaceous secretions

44
Q

What does the pacinian corpulse look like? What is its function? Where are these located?

A

cut onion
Mechanoreceptor
Dermis

45
Q

What do Meissner’s corpuscles look like?

A

Swirly thingy

46
Q

What are the histologic features of a hair follicle? (in order)

A

Hair cortex
Internal root sheath
External root sheath
Glassy membrane

47
Q

What is external to the glassy membrane of hair follices?

A

CT

48
