Anatomy and Physiology Module 2 Flashcards
Epithelial Tissue
makes up the linings of organs and forms glands.
connective tissue
supports, binds, and insulates
free surface
the top surface of ET, open to its surroundings
basal surface
the underside of the cell
basement membrane
the “glue” that holds the basal surface to whatever tissue is underneath (avascular)
avascular
lacking blood vessels
stratified epithelial tissue
layered
simple epithelial tissue
one-layer
squamous
flat
cuboidal
cubed shaped
columnar
tall like a column
goblet cells
cells that produce mucus
mucus
mixture of fluids, proteins, and carbohydrates that covers, protects, and lubricates a free surface within the body
keratin
waterproofing protein
pseudostratified
“false” “layered” (can touch the floor but not all the ceiling)
exocrine glands
glands that secrete substances through ducts
endocrine gland
ductless glands that secrete hormones into the bloodstream
merocrine gland
exocrine glands that secrete without losing cellular material
apocrine
exocrine glands that have cytoplasm in their secretions
holocrine glands
exocrine glands that have secretions made up of disintegrated cells
extracellular matrix
the chemical substances located between connective tissue cells
types of connective tissue proper:
loose connective tissue, adipose tissue, dense irregular, and dense regular
fibroblasts
spindle-shaped cells that form connective tissue proper
stromal cells
supporting cells that provide structure or support for parenchymal cells
parenchymal cells
“performance” cells that provide the actual function of the tissue
labile cells
cells that undergo mitosis regularly and quickly
stable cells
cells that do not regularly undergo mitosis but are able to
permanent cells
cannot undergo mitosis
chondroctyes
cells that produce special extracellular material
