|
exocrine -
|
actually secretes onto surface or into a duct
|
|
|
endocrine
|
just kind of seeps out of the cell wher eit enters blood or lymph, NO DUCT WORK
|
|
|
paracrine
|
secretes product to neighboring cells, but do not enter the vascular system
|
|
|
autocrine
|
cells respond to their own product
|
|
|
merocrine
|
mode of secretion - most gland
no cell loss, just secreted material |
|
|
apocrine
|
the tip part of the cell is secreted but the rest remains intact
|
|
|
holocrine
|
the whole cell becomes the secretion = autolysis
|
|
|
different classifications of glands-
|
tubular ( straight, coiled, or branched)
|
|
|
acinar (sn?)
|
alveolar ( can be single or branched )
|
|
|
what does simple coiled tubular look like under a microscope?
|
a bunch of dots
|
|
|
branched vs compound?
|
branched refers to secretory elements, compound refers to ducts
|
|
|
what type of glands are the meibomian glands?
|
simple branched acinar
|
|
|
secretory products - mucus
dyes? |
slimy and viscous, rich in carbohydrates,
with H&E, carbohydrates don't show up so cell looks empty |
|
|
secretory products - serous
makeup, apperance? appearance of product? |
proteins and watery,
appears purple because basal part is composed of ER, which has ribosomes ( nucleic acids ) -product appears pink |
|
|
stroma
|
supporting connective tissue framework that holds a gland together
|
|
|
glands-- stroma?
|
supporting connective tissue holding a gland together
|
|
|
glands - capsule and septa?
|
the capsule surrounds the entire gland, the septa extends into lobules of the parenchyma
|
|
|
parenchyma
|
functional part of the gland
|
|
|
myoepithelial cells
|
contractile cells similar to smooth muscle,
surround secretory things and help them secrete |
|
|
intercalated ducts
|
the smallest intralobular duct, secretes into the lobe
|
|
|
sebaceous gland
|
oil glands, associated with hair follicels
simple acinar holocrine |
|
|
meibomian glands
synonym? |
modified sebaceous,
aka tarsal holocrine, simple branched acinar ducts open onto eyelid, makes lipid layer of the tear film! |
|
|
glands of zeis
only associated with what? |
look similaar to meibomian, but smaller
simple branched acinar only associated with eyelashes |
|
|
eccrine sweat glands
|
eyelids, simple coiled tubular, not associated with hair
merocrine |
|
|
apocrine sweat glands, aka?
|
glands of moll, simple coiled tubular, secrete lipidy sweat
|
|
|
lacrimal glands
|
compound tubuloalveolar serous, merocrine, produce aqueous layer of tear film
|
|
|
glands of krause and wolfring
|
compound tubuloalveolar serous
|
