What else can I help you with?
Are collections of neuron cell bodies associated with nerves in the PNS?
Yes, collections of neuron cell bodies associated with nerves in the peripheral nervous system (PNS) are known as ganglia. Ganglia can contain cell bodies of sensory neurons (dorsal root ganglia) or autonomic neurons (autonomic ganglia) that help relay information to and from the central nervous system.
What contains sensory neuron cell bodies?
The sensory neuron cell bodies are located in clusters called ganglia. These ganglia can be found either outside the spinal cord (dorsal root ganglia for most spinal nerves) or within the sensory organs themselves (such as in the eye or ear).
Where are large groups of neuron cell bodies likely to be found?
dorsal root ganglion
Where neuron cell bodies located?
The cell body, called the SOMA, is the main part of the neuron. It is the main metabolic center or region of the neuron. The neuron has 3 parts: DENDRITES (inputs), SOMA (cell body), and AXON (output). The axon is the part which FIRES when sufficient inputs reach it at the axon hillock.
What is smallest neuron or ganglion in nervous system?
The smallest neurons in the nervous system are called granule cells, which are found in the cerebellum. Ganglia are clusters of neuron cell bodies outside the central nervous system, and the smallest ganglion is likely to vary depending on location in the body.

Ganglia can contain cell bodies of sensory neurons (dorsal root ganglia) or autonomic neurons (autonomic ganglia) that help relay information to and from the central nervous system.
What structure contains cell bodies of neurons?
The neuron cell body is called the soma.
Collections of neuron cell bodies associated with nerves in the PNS?
Ganglia
What are collections of neuron cell bodies associated with nerves in the PN?
Ganglia
What is gray matters composed of?
cell body of neurons
Where are the cell bodies for the second order neurons located?
Second order neuron cell bodies reside in the dorsal horn of the spinal cord.
What contains sensory neuron cell bodies?
The sensory neuron cell bodies are located in clusters called ganglia. These ganglia can be found either outside the spinal cord (dorsal root ganglia for most spinal nerves) or within the sensory organs themselves (such as in the eye or ear).
Define relay neuron?
a relay neuron is the neuron that picks up the message from the sensory neuron and delivers it to the motor neuron in the spinal cord or the brain
What is the PNS glial cell that surrounds neuron cell bodies in ganglia?
In this case it is satellite cell. In the PNS system there are only two types of cells which are in the neural structures outside the CNS, Schwann Cells and Satellite cells. The Satellite cells surround neuron cell bodies in ganglia.
Are motor neuron cell bodies located in the gray or white matter?
gray matter
What are chemicals which relay amplify and modulate between a neuron and another cell?
Neurotransmitters are chemicals that send messages from one cell to another.
Are motor neuron cell bodies located in the the gray or white matter of the spinal cord?
gray
