The Nervous System Flashcards
1
Q
Sensory receptor
A
Detect stimuli e.g. Pressure
cells in skin
2
Q
Sensory neuron
A
Long axon carries impulse
from receptor to spinal
cord.
3
Q
Synapse
A
Gap where neurones meet.
Chemical message using
neurotransmitter.
4
Q
Relay neurone in CNS
A
Allows impulses to travel
between sensory and motor
neurones in the spinal cord.
5
Q
Motor neurone
A
Long axon carries impulse
from receptor to effector.
6
Q
Effector
A
Muscle or gland that carries
out response.
7
Q
Reflex action
A
Stimulus~> sensory receptor~> relay neurone in CNS~> motor neurone ~> response
8
Q
CNS
A
Central Nervous System
9
Q
