Types of neurons-function of transmitted neural impulse

Question

According to the function of transmitted neural impulse what are the types of neurons? How dissimilar are the concepts of efference and afference of the neural impulse transmission?

Answer 1

There are three kinds of neurons: afferent neurons, efferent neurons and interneurons. Afferent neurons are such that only transmit sensory information from tissues to the neural nuclei and ganglia (that is, where they make connection with the interneurons or effector neurons). Efferent neurons are such that it transmits commands to tasks executed in several portions of the body. Interneurons, also termed as association neurons or relay neurons, serve as connection among two other neurons. Afference is conduction of sensory impulses and efference is a conduction of effector impulses (that is, impulses which command somebody action).
