Sympathetic nerve postganglionic fiber neurotransmitters predominantly comprise. Ganglia can be thought of as synaptic relay stations between neurons. Sympathetic efferent pathways form a component of the autonomic nervous system. The spinal cord is an essential link between the peripheral nervous system and the brain it conveys sensory information originating from different external and.

The somatic nervous system is made up of sensory receptors that. Antagonist and postural muscles can be coordinated with the withdrawal, making the connections more complex. A withdrawal reflex from a painful stimulus only requires the sensory fiber that enters the spinal cord and the motor neuron that projects to a muscle.

A ganglion is a collection of neuronal bodies found in the somatic and autonomic branches of the peripheral nervous system (PNS). The somatic nervous system maintains communication between the CNS and the outside world.
