Peripheral Nervous System (PNS) original answer by btbchris
multipolar neuron
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).
Peripheral Nervous System (PNS) original answer by btbchris
The two nerves that carry preganglionic axons to the parasympathetic ganglia are the cranial nerves and the sacral spinal nerves. Specifically, cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus) are involved. Additionally, the sacral spinal nerves S2 to S4 contribute to the pelvic splanchnic nerves, which also carry preganglionic parasympathetic fibers. These pathways play a crucial role in the parasympathetic division of the autonomic nervous system, facilitating various involuntary functions.
Cranial nerves and spinal nerves.
Ganglion or ganglia .
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.
The peripheral nervous system consists of all the spinal nerves and cranial nerves. These nerves connect the central nervous system (brain and spinal cord) to the rest of the body, allowing for communication and control of bodily functions.
somatic
The preganglionic fibers of the autonomic nervous system travel through the cranial nerves (in the head) and the spinal nerves (in the rest of the body). They synapse with postganglionic neurons in autonomic ganglia before reaching their target organs.
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.
