1

thyroid gland

2

parafollicular cells

3

what slide is this? 

thyroid 

4

thyroid slide

 

cuboidal follicular cell

5

What is this? What kind of gland is it (how do you know)?

Sweat gland

simple tubular coiled gland

A simple gland has an unbranched duct (or no duct at all).  There is only a single secretory unit

6

What is this? What cells are found here?

Sweat gland

cells: 

1. dark cells - near lumen in the center

2. pale cells - periphery, clear

3. myoepithlial cells - lines periphery, with triangular shaped nuclei

7

What are these cells (how do you know)? Where are they found?

Myoepithlial cells

1) in sweat gland

line the periphery and have triangular shaped nucleus

 

2) also found in intralobular ducts

8

What is top portion of this picture (how do you know)

Sweat gland DUCT

know: b/c has stratified cuboidal epithelium, meanders through dermis to terminate on skin surface

9

What are the bottom arrows? What type of gland is this?

Sebaceous gland

round or pear shaped, clear or lavender

SIMPLE BRANCHED ACINAR GLAND

10

What is this? What type of muscle?

Erector pili in scalp slide, between hair follicles

smooth muscle

11

What muscle can be found between hair follicles?

Erecti pili - smooth muscle

12

What are thse cells in a sebaceous gland?

stem cells - basophillic

13

What are these cells? What does this signifify?

Pyknotic cells in sebaceous gland 

pyknotic means condensed nucleus 

 

 

these cells are dying and will soon lyse. Ultimately, cells lyse and their lipid-filled cytoplasm becomes sebum 

14

What is this? what does its presence indicate? what type of gland is it?

Islet of langerhans

indicates you are in the pancreas

endocrine gland

15

what is this? What is secreted here?

Islet of langerhans

a cell -> glucagon

b cell -> insulin

∂ cell -> somatostatin

F or PP cell -> pancreas polypeptide

16

what is the gland around the "island" in the middle? what type of gland is this?

exocrine pancreas around the islet of langerhans

acini cells are stained bright red

compound acinar gland

17

what cell is this in the pancreas? (how do you know)

where does its product go?

serous acini cell

brightly red

product enters into intercalated duct

18

what is this in the pancreas (how do you know)? what does it secrete?

Interlobular ducts:
Low columnar epithelium

Also secrete bicarbonate-rich fluid. 

 

Located between lobules, within the thin connective tissue septa that separate lobules.  

19

what is this in the pancreas? waht does it secrete?

intercalated duct

looks collapsed on itself

produces bicarbonate, stimulated by secretin

20

what cell is this in the pancreas? what stimulates it? 

what does this cell lack?

intercalated ducts

stim. by secretin

lacks secretory granules

21

what is red? blue (in the pancreas)

red -- centroacinar cell -- pale staining

blue -- serous acinus cell 

22

what is this in the panceas

centroacinar cells

pale staining little round ducts

23

What is this? what type of gland is it?

Submandibular glanda

predominance of the serous acini

compound tubuloacinar gland. By definition, as in all compound glands, the conducting portion is branched 

24

What is this? What type of acni does it have

Submandibualr gland

mostly serous acni (so look for redish color), but also has mucoous acni and mixed acni

25

Mixed acinus 

both mucous and serous cells that secrete into a common lumen.  

26

what is this? what is it lined by?

Intralobular duct

intralobular duct of submandibular has striations at the basal surface of their cells.  

lined by  simple columnar epithelium 

27

2 Notable features of Intralobular ducts (in the submandibular)

Intralobular ducts

1. when you close condense, appears striated due to  the parallel arrays of the mitochondria within the infolds of the plasma membrane at the basal surface of the cells. 

2. myoepithlial cells

28

what is this tissue? (how do you know)

tongue

papillae on one surface (absent on ventral)

skeletal muscle in middle

have von ebners glands

29

what is this(how do you know)? what tissue is it found? 

circumvallate papillae in the tongue

1. has taste buds (pale ovals)

 

30

type of epithelium on the tongue?

 

stratified squamous surface epithelium
