Q

example of coiled tubular gland

A

sweat glands of skin

17
Q

Example of branched tubular gland

A

Fundic, pyloric, and cardiac glands of stomach

18
Q

Example of Alveolar (Acinar)

A

Meibomian glands of eyelid Sebaceous glands of skin

19
Q

Tubuloalveolar (-acinar)

A

Salivary glands, brunner’s glands of duodenum, and mucous glands of esophagus

20
Q

Glands of the oral cavity are an example of what kind of excretory

A

Branched tubular glands

21
Q

Exocrine glands of the pancreas are an example of what kind of excretory duct

A

branched acinar/alveolar gland

22
Q

The mammary gland is an example of what kind of secretory duct

A

branched tubuloacinar gland

23
Q

what is a serous demilune

A

commonly found in Acinus mostly mucous capped by a half-moon shaped group of serous cells

24
Q

where can mixed glands be found

A

Submandibular and sublingual

25
Q

List the mechanisms of secretion from thinnest product to thickest

A

merocrine (eccrine), Apocrine, holocrine

26
Q

Merocrine (eccrine)

A

secretory product is typically stored in membrane-bound vesicles, and cytoplasm/cell membrane is retrieved in an exocytosis/endocytosis cycle Cell is not damaged in this type of secretion

27
Q

Apocrine

A

apical cytoplasm is released along with secretory product example: axillary sweat glands Part of the cell is damaged

28
Q

Holocrine

A

Entire cell is released as part of secretory product example: sebaceous gland Entire cell is lost

29
Q

Submandibular gland

A

Both serous and mucous cells serous cells form serous delimit capping mucous acini myoepithelial cells surround acini

30
Q

Sublingual gland

A

Mucous acini (pale in appearance) (PAS+) flattened nuclei at basal poles of cells myoepithelial cells surround acini

31
Q

Parotid gland

A

Serous Acini Apical regions contain zymogen granules RER predominates in basal regions of secretory cells - this makes sense because zymogen granules are protein containing granules
