What are nerves made of?

Nerves are composed of myelinated and unmyelinated axons, Schwann cells surrounded by connective tissue.

Where is the nervous system located?


The central nervous system (CNS) includes the nerves in the brain and spinal cord. It is safely contained within the skull and vertebral canal of the spine. All of the other nerves in the body are part of the peripheral nervous system (PNS).

How does nervous system work?

How Does the Nervous System Work? The basic workings of the nervous system depend a lot on tiny cells called neurons. For example, sensory neurons send information from the eyes, ears, nose, tongue, and skin to the brain. Motor neurons carry messages away from the brain to the rest of the body.

What are the 3 divisions of the PNS?

The autonomic nervous system is divided into three parts: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system. The autonomic nervous system controls smooth muscle of the viscera (internal organs) and glands.

How the nervous system is divided?

The nervous system of vertebrate animals is often divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord. The autonomic nervous system is then split into the sympathetic division, parasympathetic division, and enteric division.

How can I strengthen my nerves?

Eat a balanced diet. A balanced, low-fat diet with ample sources of vitamins B6, B12, and folate will help protect the nervous system. Make sure that your diet contains lots of fresh fruits, vegetables, and whole grains. Drink plenty of water and other fluids.

Does the brain have nerves?


The brain has no nociceptors – the nerves that detect damage or threat of damage to our body and signal this to the spinal cord and brain. Although the brain has no nociceptors, many of the other structures in our head do, including blood vessels, muscles, and nerves in the neck, face and scalp.

How does the brain work?

How does the brain work? The brain works like a big computer. It processes information that it receives from the senses and body, and sends messages back to the body. Brain tissue is made up of about 100 billion nerve cells (neurons) and one trillion supporting cells which stabilize the tissue.

Is the brain an organ?


A brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It is located in the head, usually close to the sensory organs for senses such as vision. It is the most complex organ in a vertebrate's body.

What are the 3 types of the brain?

The brain has three main parts: the cerebrum, cerebellum and brainstem.
  • Cerebrum: is the largest part of the brain and is composed of right and left hemispheres.
  • Cerebellum: is located under the cerebrum.
  • Brainstem: acts as a relay center connecting the cerebrum and cerebellum to the spinal cord.

How many Cerebellums are there in the brain?

They are also easily the most numerous neurons in the brain: In humans, estimates of their total number average around 50 billion, which means that about 3/4 of the brain's neurons are cerebellar granule cells. Their cell bodies are packed into a thick layer at the bottom of the cerebellar cortex.
