Detailed explanation-1: -Both of these are protected by three layers of membranes known as meninges. For further protection, the brain is encased within the hard bones of the skull, while the spinal cord is protected with the bony vertebrae of our backbones.
Detailed explanation-2: -The brain is a soft, spongy mass of nerve cells and supportive tissue. It has three major parts: the cerebrum, the cerebellum, and the brain stem. The parts work together, but each has special functions. The cerebrum, the largest part of the brain, fills most of the upper skull.
Detailed explanation-3: -Abstract. Nerve cells (neurons) have extensive processes called dendrites. These occupy a large surface area of a neuron. They receive many signals from other neurons and contain specialized proteins that receive, process, and transfer these to the cell body.
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
