Question

peripheral nervous system consists of cranial nerves arising from the brain and spinal nerves arising from the spinal cord the statement is right or wrong​

Answer 1

Answer:

The peripheral nervous system is divided into the soMatic nervoUs system and the

GutonoMic nervous system. In the soMatic nervous systeM, the cranial nerves are part of the PNS with the exception of the optic nerve (Cranial nerve 10), along with the retina. The second cranial nerve is not a true peripheral nerve buta tract of the diencephalon.

Cranial nerve ganglia originated in the CNS.

However, the remaining ten Cranial nerve

Gxons extend beyond the brain and are therefore considered part of the PNS4 The

Gutonomic nervous system exerts involuntary

Gontrol over sMooth MUscle Gnd glands. The

Gonnection between CNS Gnd organs allows the systeM to be in two different functional states: syMpathetic and parasyMpathetic.
