What part of the nervous system performs the response to a stimuli?

What part of the nervous system performs the response to a stimuli?

The peripheral nervous system (PNS) provides the connection between internal or external stimuli and the central nervous system to allow the body to respond to its environment.

What is a stimulus response in the nervous system?

A stimulus is a change in the environment (either external or internal) that is detected by a receptor. Receptors transform environmental stimuli into electrical nerve impulses. These impulses are then transmitted via neurons to the central nervous system where decision-making occurs.

Which part of nervous system controls reflex action?

Spinal cord
(a)Spinal cord controls the reflex arcs.

What are main parts of the 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.

What is a reflex in the nervous system?

Nervous system – Reflexes A reflex action often involves a very simple nervous pathway called a reflex arc. A reflex arc starts off with receptors being excited. They then send signals along a sensory neuron to your spinal cord, where the signals are passed on to a motor neuron.

What is the function of the central nervous system?

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 nervous system transmits signals between the brain and the rest of the body, including internal organs. In this way, the nervous system’s activity

What is a sensory stimulus in the nervous system?

Sensory receptors are specialized cells, usually neurons, that detect and respond to physical and chemical stimuli. Most are exquisitely sensitive to highly specific inputs, or sensory modalities, such as movement, odor chemicals or visible light photons. Considering this, what is a stimulus in the nervous system?

How does the sense organs respond to stimuli?

Each sense organ has special cells, called sensory receptors, that respond to a particular type of stimulus. Sensory receptors send nerve impulses to sensory nerves, which carry the nerve impulses to the central nervous system. The brain then interprets the nerve impulses to form a response.

What is the function of the peripheral nervous system?

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. In this way, the nervous system’s activity controls the ability to move,…
