Peripheral Nervous System (PNS) original answer by btbchris
it is made up by nerves and associated cells that are not part of the brain and the spinal cord, included here are cranial nerves that pass through openings in the skull and stimulate regions of the head and neck, spinal nerves, and ganglia(ganglia are collections of nerve cell bodies).
Cranial nerves and spinal nerves.
Ganglion or ganglia .
Peripheral nervous system consist of all of the Cranial nerves and Spinal nerves. This division is Anatomical and not Physiological.
Dorsal and ventral roots are a feature of spinal nerves only. Cranial nerves do not have dorsal and ventral roots.
Yes, the PNS contains ganglia, cranial nerves, and spinal nerves.
somatic
Yes, central nervous system is your brain and spinal cord. Cranial nerves arises from your brain stem in your midbrian/pons/medulla.
There are 31 pairs of spinal nerves which originate in the spinal cord. There are twelve cranial nerves, which are referred to by Roman numerals. Ten of the twelve cranial nerves originate from the brainstem; the other two stem from the forebrain and thalamus. The nerve that is responsible for eyebrow movement is the VII cranial nerve, also known as the facial nerve. This is one of the ten cranial nerves originating from the brainstem.
In the nerves of the peripheral nervous system; 12 cranial nerves and 31 spinal nerves.
