When they are connected together they are called nerve.
Another name for efferent neurons are motor neurons. They conduct impulses away from the nervous system.
Nerve cells are called neurons.
Afferent neurons
Yes. However, it is better put that most of the interneurons are found in the part of the CNS called the spinal cord.
Neurons
A somatic system
The motor neuron is the final common pathway for all neurons to travel to complete their synapse. Afferent neurons or unipolar neurons all pass through the cord and brain on this journey.
No, they can never be replaced. You are born with all the neurons you will ever have
They are neurons that can be found in all six of cortical layers (except layer 1), and they are excitatory projection neurons.
Neurons
Interneurons make up about 99% of all neurons. They are all in the CNS.
The scientific name for nerves is "neurons." Neurons are specialized cells that transmit information throughout the body in the form of electrical signals.
