ANATOMY

Detailed explanation-1: -The sensory input is sensing the environment and changes around an organism, and is carried out by sensory organs like eyes, ears, nose, tongue, and skin, some of them performing simultaneously.

Detailed explanation-2: -Sensory neurons are the nerve cells that are activated by sensory input from the environment-for example, when you touch a hot surface with your fingertips, the sensory neurons will be the ones firing and sending off signals to the rest of the nervous system about the information they have received.

Detailed explanation-3: -Thalamus. Located in the central part of the brain, the thalamus receives sensory messages, such as touch, from the body, and sends the messages to the appropriate part of the brain to be interpreted.

Detailed explanation-4: -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. 01-Oct-2018
