Afferent vs efferent–If you’ve ever looked up a word in the dictionary only to find that it has more than one meaning, you know the frustration of trying to figure out which definition is appropriate. For instance, a website might say “afferent” means “leading into” and then define it as “being or running towards.” Another site might define afferent as “carrying material inwards,” while another says that an afferent nerve is a nerve from the brain or spinal cord that carries impulses away from the body. For our purposes, however, all that is relevant. We are concerned about the “afferent” meaning: what does it mean when people use it to describe a nerve or a nerve impulse? The internet contains many interesting articles that describe and compare afferent vs efferent nerve impulses. However, we won’t jump directly into all that here. Instead, we’ll explain the nerve impulse first. That’s because some significant pieces of information sometimes get left out of the discussion of afferent vs efferent nerve impulses. Let’s begin by looking at the basic definition of the nerve impulse. https://trendtoreview.com/afferent-vs-efferent/
