MEDICAL PHYSIOLOGY

Detailed explanation-1: -The spinal cord runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part. This network of nerves relays messages back and forth from the brain to different parts of the body.

Detailed explanation-2: -Messages, in the form of electrical impulses, constantly travel back and forth between the brain and other parts of the body. A special cell called a neuron is responsible for carrying these messages.

Detailed explanation-3: -The brainstem is the lower extension of the brain, located in front of the cerebellum and connected to the spinal cord. It consists of three structures: the midbrain, pons and medulla oblongata. It serves as a relay station, passing messages back and forth between various parts of the body and the cerebral cortex.

Detailed explanation-4: -corpus callosum: Thick bundle of axons that lies deep inside the brain and carries messages back and forth between the two hemispheres.
