What else can I help you with?
Where are the Axons located in the spinal cord?
On the outer parts
What is the white matter of the spinal cord contain?
axons
Spinal nerve roots which contain only motor neuron axons?
the what? root of a spinal nerve consists of motor neuron 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.
Gray matter in the spinal cord is mostly?
unmyelinated axons.
Is short preganglionic axons parasympathetic or sympathetic?
Short preganglionic axons are characteristic of the sympathetic nervous system. In the sympathetic division, these axons originate in the spinal cord and project to nearby ganglia, which are typically located close to the spinal cord. In contrast, the parasympathetic nervous system features long preganglionic axons that extend from the brainstem or sacral spinal cord to ganglia located near or within target organs.
What is the structure of the spinal cord?
It is a bundle of nerve fibers (technically called axons).
The part of a spinal nerve that contains only sensory neurons is the?
The part of a spinal nerve that contains only sensory neurons is called the ventral root. There's also the axons of motor neurons and axons of sensory neurons.
Sheaths of what cells often enclose the axons outside the brain and spinal cord?
Schwann cells make the myelin sheath that encloses some axons
What part of the spinal cord contains neurons?
Motor neurons are located in the gray matter of the brain, and their axons stretch out to the spinal cord through the ventral root. they are located in the Ventral horn of the spinal cord,
Which would be found in the anterior root of a thoracic spinal nerve?
somatic motor axons
Groups of axons and dendrites in the PNS are called?
A group of axons in the CNS is most likely referring to the tracts of neurons that are found in the spinal cord.
