Detailed explanation-1: -The human brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem and the cerebellum.

Detailed explanation-2: -The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body.

Detailed explanation-3: -The brain controls what you think and feel, how you learn and remember, and the way you move and talk. But it also controls things you’re less aware of-like the beating of your heart and the digestion of your food. Think of the brain as a central computer that controls all the body’s functions.

Detailed explanation-4: -The brain has three main parts: the cerebrum, cerebellum and brainstem. Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.

Detailed explanation-5: -Brain tissue is composed of neuronal, glial and endothelial cells, and although there must be biological rules that determine the numbers of cells of each subtype and the volumes (or masses) occupied by them, little is known about such rules, if they indeed exist.
