Question 1

Broad division of the entire nervous system

Answer 1

CNS and PNS

Question 2

Subdivisions of PNS

Answer 2

• somatic efferent (motor fibres to skeletal muscle)
• somatic afferent
  (sensory fibres from skin and skeletal muscle)
• autonomic nervous system (ANS) (motor and sensory)

Question 3

Subdivisions of ANS

Answer 3

Enteric nervous system

sympathetic division

parasympathetic division

Question 4

Function of ANS

Answer 4

mediates output from CNS to the whole body (except skeletal muscle)
Regulates largely involuntary essential functions

Transmitter of sympathetic preganglionic neurones

Answer 5

Acetylcholine via excitatory nicotinic cholinoreceptors

cholinergic

Question 6

Transmitter of parasympathetic preganglionic neurones

Answer 6

Acetylcholine via excitatory nicotinic cholinoreceptors

cholinergic

Question 7

Transmitter of sympathetic postganglionic neurones

Answer 7

Noradrenaline (adrenergic)

Question 8

Transmitter of parasympathetic postganglionic neurones

Answer 8
