receptors 1.
provide the info
control center 2.
-hypothalamus
effectors 3.
response to change internal environment
what is metabolism
chem reaction which turns food into energy
Negative feedback
maintains body temp( deacrease in function in response to a stimulus): stabilizes the system
EX] sweating
Positive feedback
controlled variable stimulates its own growth (result of a reaction is amplified)
EX] ovulation; uterine contractions
anterior
toward the front
posterior
toward the back
medial
midline dividing body into L &R
lateral
toward the side
proximal
distal
close to the point of attachment
farther away from attachment
superficial
deep
near the surface
internal parts
sagittal
L&R proportions
frontal
divides into anterior and posterior
transverse
seperates into superior & inferior
How does CT scan work?
- X-ray rotates around body
- x-ray beam passes thru body and the body absorbs the rays differently and computer measures from detector
movement
change in motion
responsiveness
reaction to change
growth
increase in body size
reproduction
new organisms & cells
