Motor or efferent neurons are those that are part of the nervous system, which are also called "effector neurons", these are responsible for conducting nerve impulses outside the central nervous system to effectors such as muscles or muscles. glands, other neurons, etc. thus producing a response. But in addition the word is used to describe the possible relative connections between the nervous structures, an example of this is the synapse of an efferent neuron provides input to another neuron, and not vice versa; an opposite activity of direction or sense is called afferent.
The main function of motor neurons is to send the different nerve impulses that are produced in our body, outside the CNS or central nervous system to the effectors, which are cells in charge of generating responses, secreting substances and movements, therefore, in In other words, motor neurons carry signals from the spinal cord to each of the muscles in order to produce movement in the body.
The interface between the muscle fiber and a motor neuron is a specialized junction called the neuromuscular junction. After appropriate stimulation, the efferent neuron emits a large number of neurotransmitters that fuse to postsynaptic receptors and unleash a response in the muscle fiber that leads to movement of the muscles. The cell body of this neuron binds to a single, long axon along with various dendrites emerging from the cell body itself.
