Neurone
Nerve cells transmit the information as electrical impulses
1 of 12
Central nervous system (CNS)
Where information from sense organs is sent and where reflexes and actions are coordinated.
2 of 12
Synapses
The connection between 2 neurones. The nerve signal is transferred by chemicals which diffuse across the gap.
3 of 12
Eyes
light receptors
4 of 12
Ears
Sound receptors and balance receptors (sensitive to changes in position)
5 of 12
Nose
Smell receptors (sensitive to chemical stimuli)
6 of 12
Tongue
Taste receptors (sensitive to bitter, sweet, sour- chemical stimuli)
7 of 12
Skin
Sensitive to touch, pressure, pain and temperature change
8 of 12
Sensory neurones
Carry signals as electrical impulses from the receptor in the sense organs to the CNS
9 of 12
Relay neurones
carry signals from sensory neurones to motor neurones
10 of 12
Motor neurones
carry signals from the CNS to the effectors
11 of 12
effectors
Muscles and glands are known as effectors. Muscles contract and glands secrete hormones
