avascular
Term
functions of epithelia
Definition
physical protection, control permeability, provide sensation by detecting changes in environment, produce specialized secretions thru the formation of glands
Term
simple epithelium
Definition
single layer of cells
Term
stratified epithelium
Definition
two or more layers of cells
Term
squamous epithelium
Definition
thin, flat and scale like cells
Term
cuboidal epithelium
Definition
cells as wide as they are tall

columnar epithelium
Definition
cells taller than they are wide
Term
exocrine glands
Definition
secretions discharged through ducts
Term
endocrine glands
Definition
secretes hormones, no ducts
Term
serous glands
Definition
produce a thin, watery secretion
Term
mix glands
Definition
contain both serous and mucous cells
Term
unicellular glands
Definition
aka goblet cells
Term
multicellular exocrine glands
Definition
glands that have a secretory part plus a duct; organization of tubular, alveolar (flask shaped) and tubuloalveolar (combination)
Term
eccrine secretion
Definition
most common mechanism, secretory vesicle formed, released by excoytosis, aka mercrine
Term
apocrine secretion
Definition
mammary gland, apocrine sweat glands; loss of secretory product
Term
holocrine secretions

melanocytes
Definition
produce pigment melanin
Term
mast cells
Definition
secrete histamine and other vasoactive substances (act a blood vessels)
Term
lymphocytes
Definition
go where tissue infection or inflammation occurs
Term
collagen fibers
Definition
long, most common (type 1)found in tendons and ligaments
Term
reticular fibers
Definition
type 3 collagen, thinner than typical, form framework of organs
Term
elastic fibers
Definition
made of protein called elastin, branching, ability to recoil

neurons and neuroglia (nerve glue)
Term
neurons specialized for
Definition
irritability and conductivity
Term
irritability
Definition
ability to recieve a stimulus
Term
conductivity
Definition
ability to convey an impulse to some location
Term
soma

cell body of neurons
Term
dendrites
Definition
branching structures, conduct impulses toward the cell body
Term
axon
Definition
rarely branches, usually insulated by myelin; conduct impluses away from cell body
