type of neurone for interneurone, sensory and motor
bipolar, unipolar and multipolar
3 of 10
describe nerve structure
bunch of axons insdie perineurim and enclosed in epineurim
4 of 10
describe action potential stages
-70mV at rest, stimulus into dendrites and ligand gated chanles open causing stimulus, if stimulus/voltage if large enough the voltage gated na ion chanels open and imupluse propogated along axon. all or nothing. action potential +30mV
5 of 10
repolarisation stages
na+ ion chanels close and k+ open so k+ move out and membrane becomes repolarised, refractory period as na+and K+ ions rebalanced
6 of 10
how r impulses propagated
na voltage chanels only open in respond to local current changes so previous ones close and only travels in 1d
7 of 10
inhibitory vs excitory impulses
gaba and acetlycholine
8 of 10
whats white matter vs grey matter
white is axons, greys is cell bodies
9 of 10
how many spinal chord nerves , there nmes
31, cervcial, thoracic, lumbar, coccygeal,sacral
