How does the nervous system communicate information?

In both the nervous and the endocrine system signals are passed from one cell to another by chemical communication. In the nervous system, nerve cells send messages electrochemically: this means that chemicals cause an electrical impulse from one cell to another.

How does the nervous system process information?

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.

How does the nervous system respond to sensory information?

In the sensory centers of the brain or in the spinal cord, the barrage of input is integrated and a response is generated. The response, a motor output, is a signal transmitted to organs than can convert the signal into some form of action, such as movement, changes in heart rate, release of hormones, etc.

Which organ is part of our nervous system?

The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord. 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 central nervous system has a fundamental role in the control of behavior. It contains the brain and the spinal cord which are both encased in bone which shows their importance. Both the brain and spinal cord receive signals from the afferent neurons and send signals to muscles and glands through efferent neurons.

Why do we need nervous system?

What nerve sends signals to brain?

Sensory nerves send information such as touch, temperature, and pain to the brain and spinal cord. Motor nerves send signals from the brain back into the muscles, causing them to contract either voluntarily or reflexively.

What are the three types of nervous system?

  • Loss of sight or double vision.
  • Memory loss.
  • Impaired mental ability.

Which body part sends messages to the brain?

The peripheral nervous system carries messages to and from the central nervous system. It sends information to the brain and carries out orders from the brain. Messages travel through the cranial nerves, those which branch out from the brain and go to many places in the head such as the ears, eyes and face.

How do you know if your central nervous system is damaged?

A few examples of symptoms that may be caused by a nervous system problem include: Numbness or tingling. Weakness or a reduced ability to move any part of the body (not caused by pain). Tremors, tics, or other unusual movements, such as a walking (gait) change or mouth smacking.
