secrete hormones into bloodstream (no duct)
endocrine glands
cannot undergo mitosis
permanent
4 types of connective tissue
epithelial
connective
nervous
muscle
"Glue" at the bottom that is avascular
basement membrane
membranes that lubricate joints
synovial
have cytoplasm in secretions
apocrine glands
can undergo mitosis if needed
stable
Epithelial tissue, located in stomach and intestines, absorbs and secretes, single layer, tall column-like structure
simple columnar
membranes at all openings to the outside of the body
mucous membranes
loose connective
have secretions made of disintegrated cells
provide structure or support (no actual function)
stromal
Connective tissue proper that provides insulation under the skin with cells filled with oil
adipose
elastic
reason chondrocytes cannot live in cartilage
too firm of ground substance
secrete without losing cellular material
merocrine glands
undergo mitosis routinely
labile
Cartilage in the joints of the backbone that provide binding and resilient support
fibrocartilage
how epithelial cells get oxygen and nutrients
diffusion
result of replacement by stromal cells
not functioning
secrete outward through a duct
exocrine glands
provide actual function of tissue
parenchymal
pseudostratified columnar
location of serous membranes
around organs (to keep lubricated and prevent rubbing)
chondrocytes live here
