What are the two types of nerves?

The main 2 types of nerves are sensory nerves and motor nerves.Sensory nerves also known as afferent nerves, carry impulses from sensory receptors towards the brain.Motor nerves also known as efferent nerves, carry impulses away from the brain to muscles and glands.

How do nerves work in the human body?

The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain.

An example of this is the stretch reflex. … Memory and learning. … Voluntary control of movement.

Why nervous system is very important?

The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.
