When they are connected together they are called nerve.
Nerve cells are called neurons.
Afferent 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.
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.
Another name for an efferent neuron is a motor neuron. These neurons carry signals from the central nervous system to muscles, glands, and other effector organs in the body, enabling them to respond to stimuli.
They are neurons that can be found in all six of cortical layers (except layer 1), and they are excitatory projection neurons.
Neurons
All three types of neurons (sensory neurons, motor neurons, and interneurons) have a cell body, dendrites, and an axon. They are all involved in transmitting signals within the nervous system, with sensory neurons responsible for conveying sensory information to the brain, motor neurons for transmitting signals from the brain to muscles and glands, and interneurons for connecting other neurons within the central nervous system.
The scientific name for nerves is "neurons." Neurons are specialized cells that transmit information throughout the body in the form of electrical signals.
