b10 Flashcards
step 1
stimulus ->
receptor
2
receptor ->
sensory neurone
3
sensory neurone ->
central nervous system
4
central nervous system ->
motor neurone
5
motor neurone ->
effector (muscle)
6
effector (muscle) ->
response
what are reflexes
automatic responses made by your nervous system without thinking
examples of reflexes
knee jerk, eye blink
do reflexes involve the conscious part of your brain
no
what is the pathway taken by the impulse in a reflex called
the reflex arc
why is the reflex arc faster
it doesn’t involve the brain
what are the gaps between a neurone called
synapses
how do neurones communicate across synapses
using chemical neurotransmitters
energy type for the impulse across a synapse
electrical, chemical and then electrical
what do synapses allow
blocking of receptors and therefore pain suppression
