Q. According to the function of the transmitted neural impulse which are the types of neurons? How different are the concepts of afference and efference of the neural impulse transmission?

There are three types of neurons that are efferent neurons, afferent neurons and interneurons. Afferent neurons are those that only transmit sensory information from the tissues to nuclei, neural and ganglia where they make connection with interneurons or effector neurons. Efferent neurons are those that transmit commands to tasks performed in several parts of the body. Interneurons also known as association neurons or relay neurons serve as connection between two other neurons.

Afference is the conduction of sensory efference and impulses is the conduction of effector impulses (impulses that command somebody action).
