Where is the cell body of a sensory neurone in the somatic nervous system?
Dorsal Root Ganglia
1 of 9
Where is the cell body of a motor neurone in the autonomic, sympathetic nervous system?
Autonomic Ganglian
2 of 9
What is the function of a ventral root?
It carries impulses away from the spinal chord to effectors
3 of 9
What is the function of the somatic nervous system?
To tke impulses to skeletal muscles
4 of 9
Is the Somatic nervous system 'self minding'
No
5 of 9
What is the function of the Dorsal Root
To take impulses from receptors towards the spinal chord
6 of 9
In the parasympathetic nervous system where do the nerve pathways start?
From the brain, top of the spinal chord and at the base of the spinal chord
7 of 9
What affect does a nerve impulse from the sympathetic nervous system have on the SAN (sino atrial node)?
Increase the rate of contraction and therefore increase heartrate
8 of 9
What effect does an impulse from the parasympathetic nervous system have on the pupil in the eye?
Causes the circular muscle to contract
