Increased somatic nervous system activity has which effect on the motor neurons?
A) increased release of ACh from the post-ganglionic motor neuron
B) increased release of NE from the somatic motor neuron
C) increased release of ACh from the somatic motor neuron
D) increased release of NE from the post-ganglionic motor neuron

Question

Quizplus · Accepted Answer

Increased somatic nervous system activity leads to an increased release of acetylcholine (ACh) from the somatic motor neuron. This ACh then binds to nicotinic receptors on skeletal muscle cells, leading to muscle contraction. There is no involvement of noradrenaline (NE) in the somatic nervous system.
