Unicellular exocrine
31
Goblet cells have a a basal nucleus surrounded by ___ and a ____ just above the nucleus, and an apical end filed with ____ that contains
RER large Golgi complex large secretory granules mucins.

Holocrine
37
List the characteristics of the pancreas
Merocrine Compound acinar Serous
38
List the characteristics of the salivary glands
Merocrine Compound tuboacinar
39
List the characteristics of the sebacous glands
Holocrine Simple brached acinar
40
Merocrine glands secrete their products, (usually containing proteins), by means of___ at the___
exocytosis apical end of the secretory cells.
41
Most exocrine glands are_
merocrine
42
In holocrine gland, secretion is produced by the • Both secretory products and cell debris are discharged into___
disintegration of the secretory cells themselves as they mature. lumen of the gland.
43
Peripheral cells in the holocrine gland are filled with ___, become metabolically inactive as they mature
lipid-rich granules
44
secretion involves loss of a large membrane-enclosed portion of apical cytoplasm, usually containing one or more lipid droplets.
Apocrine
45
The apical portion of the cell may subsequently break down to release its contents during passage into the duct.
Apocrine
46
characterized by the discharge of the secretory product with a pinched off portion of the apical cytoplasm
Apocrine
47
What does the released droplets of the apocrine cell contains
Lipids
48
Shape of serous cells
Roughly pyramid shaped
49
The apical ends are eosinophilic due to the abundant immature and mature secretory granules present there
Serous
50
show abundant RER, Golgi complexes, and secretory granules
Goblets Serous cells Mucous
51
Larger? Mucous or serous
M
52
apical region and most of the other cytoplasm of mucous cell are filled with secretory granules containing mucin
Mucous only Serous is wrong because it doesn’t have mucin
53
The basal region contains the RER, nucleus, and a well-developed Golgi apparatus.
Mucous
54
The RER and Golgi in___ cells are very rich in enzymes called ___ which
mucous glycosyltransferases attach sugars to polypeptide chains to make glycoproteins
55
contains many glycoproteins with important water-binding properties.
Mucous
56
Mucous cells have ___ nuclei, while serous cells have ___ nuclei
flat Basal Round , oval
57
Clumps of serous cells at the ends of some mucous tubules appear as crescent shaped structures called
serous demilunes
58
Myoepithelial Are located between
Base of epithelial cell on the basal lamina
59
Star shaped
Myoepithelial cells.
60
Long processes embrace the acinar cells
Myoepithelial
61
Specialized for contraction-they have actin and myosin
Myoepithelial
62
____ can be stained, unlike ___ which stains lightly
Myoepithelial Serous
63
Why are protein secretory cells are a good example of exocrine?
Because their apical end is associated with lumen and their basal end has capillaries for nutrients Not sure revise that they are exo
64
Cells are rich in rough endoplasmic reticulum , Golgi apparatus and prominent nucleus
Protein secreting cells
65
Why is steroid secreting cells a good example of endocrine?
Their microvilli end (apical ) is associated with capillaries to dump their products into the blood stream
66
Mitochondria with variable shape are located in the abundant cytoplasm.
Steroids secreting cells
67
___ has 1 nuclei while ___ has more than one
Protein secreting cells Steroids secreting cells
68
Have a prominent nuclei
Protein and steroids secreting cells
69
What is the mechanism by which almost all nutrients ions and other substances are absorbed into the blood from the intestine
Sodium enters by diffusion through the apical side Through active transport using Na/Kase, The sodium ions are transported to the connective tissue side against the concentration gradient. Therefore the water movement, osmosis will move from inside the cell to outside the cell to dilute the high concentration of sodium. 
70
Ion and water absorption is from the ____ to the___ While Ion and water secretion is from the ____ to the___
Lumen , blood Blood, lumen
71
Goblet cells contain
Mucins
