Where are somatic motor neurons located?
in the CNS
Which neuron is located entirely within the cns?
Interneurons are neurons that are entirely located within the central nervous system (CNS). They act as a bridge between sensory and motor neurons, integrating and transmitting signals within the CNS.

What are 3 types of neurons?
Functional types of neurons: 1. sensory (afferent) neurons - input to CNS from sensory receptors; dendrites located at receptors, axons in nerves, cell bodies in ganglia outside the CNS 2. motor (efferent) neurons - output from CNS to effectors cell bodies and dendrites located in the CNS, axons in nerves 3. interneurons - communicate and integrate information within the CNS; located entirely within the CNS

What are neurons entirely within the cns?
Interneurons are neurons entirely within the central nervous system (CNS). They function to relay signals between sensory neurons and motor neurons, allowing for complex processing and integration of information within the CNS.
Are all the efferent neurons motor all the afferent neurons sensory and all the CNS neurons inter neurons?
Not all efferent neurons are motor; some can be autonomic (meaning they control involuntary functions). Similarly, not all afferent neurons are sensory; some can be visceral (relaying information from internal organs). CNS neurons can include interneurons that integrate and transmit signals between sensory and motor neurons, but not all CNS neurons are interneurons, as there are also sensory and motor neurons found within the CNS.
What The two types of cells of the nervous system are?
Neurons or the nerve cells are the basic unit of nervous system. Based on their function (as in whether they transmit impulse from the CNS or to the CNS) neurons are classified as sensory neurons (carry impulses to the CNS), motor neurons (carry impulses from the CNS to the target organ) and mixed neurons which perform both the functions. The neurons can also be classified based on the number of associated axons or even presence or absences of axons.
Cells located between neurons in the CNS?
The two types of cells in the CNS are neurons and glia. There are many types of glia, including oligodendrocytes, astrocytes, and microglia, each with different functions. In general, glia support neuronal function.
What are the three classes of neuron?
The three classes of neurons are sensory neurons, motor neurons, and interneurons. Sensory neurons transmit sensory information from sensory organs to the central nervous system (CNS), motor neurons carry signals from the CNS to muscles and glands to control movements, and interneurons facilitate communication between sensory and motor neurons within the CNS.
Almost 50 percent of the volume of neural tissue in the CNS is made up of what?
Roughly 50 percent of the volume of neural tissue in the CNS is comprised of glial cells. These cells provide support and protection for neurons, aiding in functions like insulation, nutrient supply, and immune defense. Glial cells also contribute to the maintenance of the blood-brain barrier.
