Flashcards in Lab 3 Deck (57):
1

Where are nuclei found in goblet cells?

At the base

2

What is the epithelial classification of sebaceous glands?

Simple alveolar gland

3

What type of secretion do sebaceous glands utilize?

Holocrine secretion

4

Where are the nuclei of the cells of sebaceous glands?

Centrally located

5

Why is characterisitc of the cytoplasm of sebaceous gland cells? What brings this about?

Clear, due to high lipid content

6

What can you see in cross section of coiled glands?

Both secretory part, and ductal part

7

How do the secretory and ductal parts of SWEAT glands stain?

Secretory is light, ductal is dark (note that this is the OPPOSITE as usual)

8

What type of epithelium comprises the ducts of sweat glands?

Stratified cuboidal

9

Multicellular sheet in the stomach secrete what?

Mucus

10

What type of epithelium comprises multicellular sheets?

Simple columnar

11

What type of cells are beneath the multicellular sheets?

Branched tubular glands

12

What is the classification of the duodenal glands?

Simple branched tubular

13

What is the classification of the intestinal glands?

Simple tubular

14

What type of cells are found in the parotid gland?

Compound acinar glands

15

What are acini?

Secretory units within an acinar gland

16

Each cell within a acini is called what?

Acinar cells

17

What type of secretions do the acinar cells of the parotid gland produce?

watery serous secretions

18

Multiple acini together form what?

A lobule

19

What are the ducts that pierce through acinar lobules?

Intralobular ducts

20

What are the ducts that are found between acinar lobules?

Interlobule duct

21

What will you see around an intralobular duct? Interlobuler?

Intralobular -acinar cells
Interlobular - CT

22

Striated ducts within the parotid glands are of what type: inter or intraloular?

Intralobular

23

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

Mitochondria

Nuclei are pushed to the apical domain (toward duct)

24

What type of gland is the submandibular gland? Why?

mixed, there are both serous cells and mucus cells

25

How do mucus cells appear in the submandibular gland?

Lightly stained, with nuclei in the basal domain

26

How do serous cells appear in the submandibular gland?

Darkly stained, acidophilic

27

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

Serous cells

28

What are serous demilunes? What are they produced by?

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

29

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

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

30

What type of ducts are found in the sublingual gland?

Intralobular striated duct

31

What type of gland is the pancreas?

Compound acinar gland

32

Intercalated ducts are of what type?

Intralobular

33

What are centroacinar cells?

Cells that make up the intraacinar segment of the intercalated duct

34

What does the reticular layer of the dermis contain?

Dense irregular CT and elastic fibers

35

How many layers of cells are in the stratum basale?

Single

36

How many layers of cells are in the stratum spinosum?

37

What is the basophilic chemical in the statum granulosum?

Keratohyaline

38

How many layers of cells are in the stratum granulosum?

Few

39

Where in the skin are Meissner's corpusles seen?

40

What is the classification of sebaceous glands?
