Weighing about 3 pounds in the average adult, the brain is about 60% fat. The remaining 40% is a combination of water, protein, carbohydrates and salts. The brain itself is a not a muscle. It contains blood vessels and nerves, including neurons and glial cells. The forebrain, the midbrain, and the hindbrain are the three main parts of the brain. The forebrain has two major parts called the diencephalon and the telencephalon. The forebrain is responsible for a number of functions related to thinking, perceiving, and evaluating sensory information. The midbrain, also called the mesencephalon, connects the hindbrain and the forebrain. The midbrain controls many important functions such as the visual and auditory systems as well as eye movement. 4. Portions of the midbrain called the red nucleus and the substantia nigra are involved in the control of body movement. The darkly pigmented substantia nigra contains a large number of dopamine-producing neurons.
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. 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. Cerebellum: is located under the cerebrum. The Anatomy of the Human Brain. By Benedette Cuffari, M.Sc. Reviewed by Emily Henderson, B.Sc. Each distinct part of the brain plays a different role in allowing humans to have thoughts and
Anatomy of the Brain. The brain receives information from sensory receptors and sends messages to muscles and glands. It is the centre of all conscious awareness and is divided into different lobes with different functions. It contains the cerebrum which makes up about 85% of the total mass. Anatomy of the Brain. The cerebrum is an organ that controls thought, memory, feeling, contact, coordinated movements, vision, breathing, temperature, hunger, and each cycle that manages our body. Together, the mind and spinal line that reaches out from it make up the focal sensory system. The mind sends and gets compound and electrical signs

The brain is the most complex part of the human body. This three-pound organ is the seat of intelligence, interpreter of the senses, initiator of body movement, and controller of behavior. Lying in its bony shell and washed by protective fluid, the brain is the source of all the qualities that define our humanity. Majority of cerebral cortex is used to associate. information from all cortical regions. It will combine information from all over the. brain, interpret the sensations, plan, decide and. prepare us to act. 21. Language. Aphasia is an impairment of language, usually. caused by left hemisphere damage either to.
