What else can I help you with?
Does chain ganglion contain soma from sensory neurons?
No, the chain ganglion contains cell bodies (soma) of autonomic motor neurons, not sensory neurons. Sensory neurons have their cell bodies located in the dorsal root ganglion outside the spinal cord.
Where is the nucleus located in the CNS?
In the central nervous system (CNS), a nucleus refers to a cluster of neuronal cell bodies located within the brain or spinal cord. These nuclei are typically found deep within the brain, such as in the thalamus or basal ganglia, and are involved in various functions, including sensory processing and motor control. In the spinal cord, nuclei are located in specific regions associated with different sensory and motor pathways.
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 located peripheral motor neuron cell bodies?
For spinal nerves, the general somatic efferent motor neurons have their cell bodies located in the ventral horn of the spinal cord (sometimes also called the anterior horn).Some of your cranial nerves also have motor neurons located in various nuclei of the brainstem.
Why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves?
The reason why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves is owing to nerve plexuses. These are networks of nerves all tangled together and found mostly in the limbs.
The gray horns of the spinal cord contain?
posterior part
What are the swellings on the dorsal roots of spinal nerves are known as what?
The swellings on the dorsal roots of spinal nerves are known as dorsal root ganglia. These ganglia contain the cell bodies of sensory neurons that transmit sensory information from the body to the brain.
Can spinal fluid contain HIV?
Spinal fluid from a HIV infected person does contain HIV, and in enough quantity to cause the virus to transfer.
What is the spinal cord linked to?
The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. The human spinal cord is protected by the bony spinal column. The bodies nervous system passes information for the bodies functions from the brain through the spinal cord via a massive network of nerves
Does chain ganglion contain soma from sensory neurons?
No, the chain ganglion contains cell bodies (soma) of autonomic motor neurons, not sensory neurons. Sensory neurons have their cell bodies located in the dorsal root ganglion outside the spinal cord.
Where is the nucleus located in the CNS?

These nuclei are typically found deep within the brain, such as in the thalamus or basal ganglia, and are involved in various functions, including sensory processing and motor control. In the spinal cord, nuclei are located in specific regions associated with different sensory and motor pathways.
What is the white matter of the spinal cord contain?
axons
Why are spinal nerves mixed nerves?
Spinal nerves are said to be mixes because their posterior roots contain sensory axons and their anterior roots contain motor axons.
What fibers do ventral spinal cord roots contain?
The ventral roots contain motor fibers.
What does the central nervous systems contain?
brain and spinal cord
What do the ventricles of the brain do?
They contain cerebral spinal fluid (CSF)
Are motor neuron cells bodies located in the gray or white matter of the spinal cord?
the white matter
