Functions Of The Human Brain

The human brain is not only one of the most important organs in the human body; it is also the most complex(www.verywell.com/the-anatomy-of-the-brain-2794895).

Anatomically the brain is divided into three major parts; cerebrum, cerebellum and brainstem[1]. The cerebrum consists of two hemispheres, such as right and left hemispheres. The right hemisphere controls the left side of the body, and the left hemisphere controls the right side. The left hemisphere regulates language and speech, and the right hemisphere controls nonverbal, spatial skills. If the right side of the brain is damaged, movement of the left arm and leg, vision on the left, and/or hearing in the left ear may be affected. Injury to the left side of the brain affects speech

The cerebral cortex is the outermost portion that can be divided into the four lobes of the brain which are known as The frontal lobe, parietal lobe, occipital lobe, and temporal lobe have been associated with different functions ranging from reasoning to auditory perception. Each bump on the surface of the brain is known as a gyrus, while each groove is known as a sulcus. The cerebrum is the largest and most important part of the human brain and is generally associated with brain functions related to thoughts, movements, emotions and motor functions. The outermost layer of the cerebrum is made up of neural tissues known as the cerebral cortex. The cerebral cortex is the part of the brain that functions to make human beings unique. Distinctly human traits including higher thought, language and human consciousness as well as the ability to think, reason and imagine all originate in the cerebral cortex.

The cerebrum consists of two hemispheres, such as right and left hemispheres.

The right hemisphere controls the left side of the body, and the left hemisphere controls the right side. The left hemisphere regulates language and speech, and the right hemisphere controls nonverbal, spatial skills. If the right side of the brain

• The occipital lobe is located at the back portion of the brain and is associated with interpreting visual stimuli and information. The primary visual cortex, which receives and interprets information from the retinas of the eyes, is located in the occipital lobe. Damage to this lobe can cause visual problems such as difficulty recognizing objects, an inability to identify colors, and trouble recognizing words.

The brainstem is located at the bottom of the brain and connects the cerebrum to the spinal cord. The brainstem is like a hard drive of a computer and it is the main control panel of the body. It controls vital functions of the body, including breathing, consciousness, movements of the eyes and mouth, and the relaying of sensory messages (pain, heat, noise etc), heartbeat, blood pressure and hunger. The brain stem is comprised of the hindbrain and midbrain. The hindbrain contains structures including medulla, the pons and the reticular formation.

• The Hindbrain is the structure that connects the spinal cord to the brain.

– The medulla is located directly above the spinal cord and controls many vital autonomic functions such as heart rate, breathing and blood
