Question

T/F. Autonomic ganglia are sights of synapse and information transmission from preganglionic to postganglionic neurons.

Answer 1

Answer:

True

Explanation:

There are two components of efferent/motor nervous system.

1.Autonomic Nervous System

It innervates the smooth muscles, glands and cardiac muscles and is under involuntary control. ANS is further divided into Sympathetic nervous system and parasympathetic nervous system.

It is composed of preganglionic neurons and postganglionic neurons. The axons of preganglionic neurons synapse on the cell bodies of postganglionic neurons.

Autonomic ganglia of sympathetic nervous system form the paravertebral ganglia (long chains on either side of spinal cord) and autonomic ganglia of parasympathetic nervous system are located close to the organ which the fibers innervate.

2. Somatic Nervous system

It is responsible for voluntary control of skeletal muscles and is composed of motor nerve and the innervated muscle.
