Let's look at these interesting questions, which you can draw on for your final response. I also attached an informative article which greatly expands on this response to consider.

RESPONSE;

1. What is the neural circuitry involved in movement? What happens at the physiological level in the nervous system to make movement possible?

Making up the efferent paths of the Peripheral Nervous System are the Autonomic Nervous System (ANS) and the Somatic Nervous System. The ANS is subdivided into the sympathetic and parasynpathetic nervous systems, both of which are involved in integration of involuntary physiological processes, such as control of heart rate. Usually, but not always, these two subsystems work in opposition to regulate a physiological event. On the other hand, it is the Somatic Nervous System that controls either voluntary or involuntary motor events which always involve muscle contraction. At the physiological level, nerves releasing Ach at the neuromuscular junction (=end plate) cause the ...

Solution Summary

Autonomic Nervous Systems (ANS) and the Somatic Nervous Systems are discussed. References are also provided to justify the assertions.
