Question

Which description is NOT consistent with the sympathetic division?

long postganglionic fibers
ganglia close to the spinal cord
thoracolumbar
most innervation from the vagus nerve
most innervation from the vagus nerve
The vagus nerve innervates most of the parasympathetic division.

Answer 1

Answer:

most innervation from the vagus nerve

Explanation:

Peripheral nervous system consists of all the neurons and ganglia within the body, outside the central nervous system. It is divided into:

1. Somatic nervous system- it controls the movements of skeletal muscles which means that this nervous system is under the voluntary control
2. Autonomic nervous system- its role is to control involuntary movements of smooth muscles and glands

Autonomic nervous system consists of:

• sympathetic nervous system -responsible for the "fight and flight" reactions (stressful situations but also for maintaining homeostasis)

• parasympathetic nervous system -opposite to sympathetic system, responsible for "rest and digest" reactions (body activities at rest)

• enteric nervous system-controls digestion
