(3) tissues Flashcards
4 types of tissue
connective
epithelial
muscle
nervous
connective cells
cells surrounded by extra-cellular non-living tissue called a matrix // adipose, bone, blood, cartilage
epithelial cells
cells that line body surfaces as well as hollow cavities and canals
muscle cells
cells that contract together following stimulation // skeletal, smooth, cardiac
nervous cells (neurons)
cells that receive and transmit info and signals // motor, inter, sensory
(func) connective
protection support fill space connect [2 types: loose & fibrous // ex: adipose, bone, blood, cartilage]
(func) epithelial
covering
protection
line cavities, ducts, and blood vessels
make up exocrine & endocrine glands
(func) muscle
movement support protection walls of organs thermoregulation [3 types: skeletal, smooth, cardiac]
(func) nervous
carry info throughout the body
stimulus input
processing info
response output
(func) adipose
(aka fat) store energy padding thermal fill space support
(func) bone
support
protection
MINIMAL movement
(func) blood
gas exchange
connection
(func) cartilage
shock absorber
protection
shapes of epithelial tissue
simple cuboidal / simple columnar / simple squamous / stratified squamous
(describe) epithelial: simple cuboidal
1 layer, cubes
(describe) epithelial: simple columnar
1 layer, columns
(describe) epithelial: simple squamous
1 layer, flat irregular shaped
(describe) epithelial: stratified squamous
several flat irregular shaped layer
(def/func) muscle: skeletal
linear & cylindrical - very organized, attached to the skeletal system through tendons movement support protection thermoregulation
(def/func) muscle: smooth
walls of internal organs and larger blood vessels
movement
walls of hollow organs
(def/func) muscle: cardiac
connected to other cardiac muscles
movement [of heart]
walls of organ [heart]
(func) motor neurons
stimulus output, carry info from brain to body
