Neurons

Question 1

Sensory Neurone

Answer 1

(Nucleus in middle of cell)
. Found in receptors and carry nerve impulses to CNS
^ when reach brain translated to sensations (e.g: hearing) but some stop at spinal cord to allow quick reactions

Question 2

Relay Neurone

Answer 2

(no mylin or nodes of ranvir as too short so not needed)
. Found in CNS and allows sensory and motor neurons to communicate

Question 3

Motor Neurone

Answer 3

(A lot shorter than sensory Neurone)
. Found in CNS
. When stimulated, release neurotransmitters that bind to receptors on muscles to trigger a response which leads to movements

Question 4

All neurons share

Answer 4

. Nucleus within cell
. Dendrites = receive electrical impulses from other neurons and direct them to cell body
. Axon = carries electrical impulses away from cell body and length varies
. Synaptic Terminals = communicate with dendrites of other neurons
