neurones Flashcards
what do Sensory neurones do ?
carry impulses to the central nervous system
what do Motor neurones do?
carry impulses from the central nervous system to effector organs
where are Relay neurones found?
only in the central nervous system
what does a dendron do?
carries electrical impulses towards the cell body
what does an axon do?
carry electrical impulses away from the cell body
how does sensory neuron differ from motion neurone?
cel body in sensory is in the middle of the axon
cell body in motor neurone is at beginning
motor neurone as function?
dendrites collect impulses from cns
axon carries ive r long distances
myelin sheath speeds up trabsmission
what does myelin sheath do?
speeds up transmission bc implies jumps from one gap to another
damages myelin sheat =
movement impaired
nerve impulses to muscles would be slower
