In the spinal cord, there is a butterfly shaped structure. What does the ventral horn of this structure primarily consist of?
is: the cell bodies of motor neurons
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.
What is the difference between the dorsal root the ventral root and the dorsal root ganglion?
Ventral root is the ventral portion of spinal cord,there is no ganglion,cell body is of motor types ,cell info goes out of spinal cord of anterior horn. dorsal root is dorsal portion of spinal cord,it posses ganglion,cell body is of sensory types,information goes into spinal cord posterior horn
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.
Cell bodies of sensory neurons are collected in ganglia in the?
dorsal root of the spinal cord
Do lower motor neurons have their cell bodies in the brain and their axons in the ganglia?
brain and spinal cord
What is the portion of the spinal cord made up of cell bodies and unmyelinated axons?
Gray matter
Are motor neuron cell bodies located in the gray of white matter of the spinal cord?
gray
Are motor neuron cell bodies located in the the gray or white matter of the spinal cord?
gray
Where are large groups of neuron cell bodies found?
In the dorsal root ganglia. The dorsal root ganglia is located in the dorsal root. The cells carry sensory signals to the spinal cord.
Are motor neuron cell bodies located in the gray matter or white matter of the spinal cord?
gray
Where are cell bodies of the somatic motor neurons of the spinal nerves located?
It depends on whether it is afferent or efferent. The afferent neurons have their soma, or cell body, near the sensory receptor sites in the body tissues. The efferent spinal nerve cells have their soma near the spinal cord cord in a ganglion. The gray matter in the spinal chord is mostly made up of the cell bodies of one of the three types of neurons, afferent, or sensory neurons, interneurons, which are also called association neurons, and efferent, or motor, neurons. The interneurons have their cell bodies roughly in the middle, with the dendrites projecting out to one side (usually heavily branched) and the axon projecting out to the other but each only a short distance. In motor neurones (efferent neurone) the cell body is very much at one end, with the dendrites branched directly from and the axon projecting a long way to reach the target. These neurons also have their cell bodies in the spinal column (usually) but there just are not as many of these as there are interneurons. The sensory neurones (afferent neurones) are quite like the interneurons in structure as they have their cell bodies in the middle but the distance the dendrites and the axons projects are much greater. The allows the cell bodies from many sensory neurons to be grouped together, a fair distance from the sensing tissue, what is also referred to as as affector organ, in a structure called a ganglia (the name for a collection of cell bodies in the periphery).
