When we are asleep or unconscious, our heart rate, breathing and blood pressure continue to function because they’re regulated by the medulla.Īnd that concludes a general overview of the components of the brain.Ī.D.A.M., Inc. The medulla, with its critical functions, lies deep within the head, where it is well-protected from injuries by an extra-thick section of overlying skull. The medulla is the part of the brain stem closest to the spinal cord. Just below the midbrain is the pons, and below the pons is the medulla. The midbrain is a small portion of the brain stem located at the top of the brain stem. The top portion of the brainstem is called the midbrain. It is critical for survival because it connects the brain with the spinal cord. The brain stem is located underneath the temporal lobes and extended down to the spinal cord. The cerebellum creates automatic programs so we can make complex movements without thinking. The cerebellum is located at the back of the head underneath the occipital and temporal lobes. If the occipital lobe becomes damaged, a person could become blind, even if his or her eyes continue to function normally The occipital lobe analyzes visual information from the retina and then processes that information. The occipital lobe is located at the back of the head behind the parietal and temporal lobes. They are also important for learning, memory, and emotion. ![]() The taste center is located in the parietal lobes.Īll sounds are processed in the temporal lobe. The parietal lobes are located behind the frontal lobe towards the back of the head and above the ears. There are two parietal lobes, one on each side of the brain. The frontal lobe is also where we shape emotional reactions and expressions ![]() Voluntary body movements are controlled by a region of the frontal lobe. Here, the left side of the brain is highlighted to show the control over right arm and leg movement, and the right side of the brain is highlighted to show the control over left arm and leg movement. The left side of the brain controls the muscles on the right side of the body and vice versa. ![]() The grooves and folds increase the cerebrum’s surface area, allowing us to have a tremendous amount of gray matter inside of the skull. The cerebrum is divided into left and right sides, which communicate with each other through a thin stalk of nerve fibers. It generates the most complex intellectual thoughts and controls body movement. The cerebral cortex is the outside portion of the cerebrum, also called the “gray matter”. The brain stem is the smallest and is located under the cerebellum, extending downward and back toward the neck. The cerebellum is smaller than the cerebrum and located underneath it, behind the ears toward the back of the head. The cerebrum is the largest component, extending across the top of the head down to ear level. There are three major components of the brain. They also give us the capacity to remember numerous pieces of information. Specific groups of them, working in concert, provide us with the capacity to reason, to experience feelings, and to understand the world. The brain is composed of more than a thousand billion neurons. ![]()
