structure and function of neurons
neurons communicate with eachother by transmitting chemical and electrical impulses
sensory neurons
from sense neurons - brain
eyes/ears/tongue/skin
info is sent via the pns to the cns
long dendrites + short axons
relay neurons
carry info to and from the brain
mini, connecting neurons between sensory and motor
short dendrites and short axons
motor neurons
info from brain to muscles and glands
found in cns, controls muscle movement
short dendrites and long axons
synaptic transmission
stimulation of postsynaptic receptors by neurotransmitters resukt in either excitation or inhibition of the postsynaptic membrane
excitation
liklihood of an action potential increases so neural activity increases
inhibition
liklihood of an action potential decreases so neural activity is reduced
