Nervous system and body

Dendrite There are literally hundreds of different types of synapses. In fact, there are over a hundred known neurotransmitters, and many of them have multiple types of receptors. Molecular neuroscientists generally divide receptors into two broad groups: When a chemically gated ion channel is activated, it forms a passage that allows specific types of ions to flow across the membrane.

Nervous system and body

The cerebrum is the thinking part of the brain and it controls your voluntary muscles — the ones that move when you want them to. You need it to solve math problems, figure out a video game, and draw a picture.

Your memory lives in the cerebrum — both short-term memory what you ate for dinner last night and long-term memory the name of that roller-coaster you rode on two summers ago.

Nervous system and body

The cerebrum has two halves, with one on either side of the head. Scientists think that the right half helps you think about Nervous system and body things like music, colors, and shapes. The left half is said to be more analytical, helping you with math, logic, and speech.

Scientists do know for sure that the right half of the cerebrum controls the left side of your body, and the left half controls the right side. The cerebellum is at the back of the brain, below the cerebrum.

It controls balance, movement, and coordination how your muscles work together. Because of your cerebellum, you can stand upright, keep your balance, and move around. Think about a surfer riding the waves on his board. What does he need most to stay balanced? Nope — he needs his cerebellum! The brain stem sits beneath the cerebrum and in front of the cerebellum.

Nervous system - Wikipedia Cell Body of a Neuron The cell body is like any other cell with a nucleus or control center.

It connects the rest of the brain to the spinal cord, which runs down your neck and back. The brain stem is in charge of all the functions your body needs to stay alive, like breathing air, digesting food, and circulating blood. The brain stem also sorts through the millions of messages that the brain and the rest of the body send back and forth.

Pituitary Gland Controls Growth The pituitary gland is very small — only about the size of a pea! Its job is to produce and release hormones into your body. This gland is a big player in puberty too. This little gland also plays a role with lots of other hormones, like ones that control the amount of sugars and water in your body.

And it helps keep your metabolism say: Your metabolism is everything that goes on in your body to keep it alive and growing and supplied with energy, like breathing, digesting food, and moving your blood around. The hypothalamus knows what temperature your body should be about If your body is too hot, the hypothalamus tells it to sweat.

You Have Some Nerve!

Nervous System Physiology

It needs some nerves — actually a lot of them. And it needs the spinal cord, which is a long bundle of nerves inside your spinal column, the vertebrae that protect it.Aug 09,  · The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

The nervous system transmits signals between the brain and the rest of the body, including internal organs. The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body.

It is essentially the body's electrical. The nervous system is an organ system containing a network of specialized cells called neurons that coordinate the actions of an animal . How does the nervous system work with other body systems.

Aug 19,  · The nervous system is made up of all the nerve cells in your body. It is through the nervous system that we communicate with the outside world and, at the same time, many mechanisms inside our body are controlled.
