White matter conducts information between grey matter areas. Grey matter is involved in analyzing information. Grey and White Matter: The brain is made up of two types of tissue, grey matter and white matter. Damage to the brain stem can cause loss of consciousness.Ĭerebellum: located at the base of the skull it is a curved mass of nerve tissues that regulates balance and coordinates fine motor skills it enables us to move quickly and smoothly. The brain stem also regulates body functions such as consciousness, fatigue, heart rate, and blood pressure. Temporal Lobe: side of head above ears situated immediately behind and below the frontal lobes the temporal lobe controls memory, speech and comprehension.īrain Stem: lower part of brain, leads to spinal cord the brain stem contains nerve fibers that carry signals to and from all parts of the body. Occipital Lobe: most posterior, at the back of the head the occipital lobe controls sight. Parietal Lobe: near the back and top of the head above the ears the parietal lobe controls the ability to read, write, and understand spatial relationships. Each of the brain hemispheres and lobes, cerebellum, and brain stem has specific functions, and they all work together:įrontal Lobe: most anterior, right under the forehead the frontal lobe controls intellectual activities, such as the ability to organize, as well as personality, behavior, and emotional control. Although not usually divided into lobes, the cerebellum and brain stem both have different parts. Other important sections of the brain are the Cerebellum and the Brain Stem. There are four lobes in each half of the brain: the Frontal Lobe, Temporal Lobe, Parietal Lobe, and Occipital Lobe. The hindbrain is divided into metencephalon (cerebellum) and myelencephalon (pons and medulla oblongata). Each half of the brain is divided into main functional sections, called lobes. The brainstem includes the diencephalon, mesencephalon (midbrain), and rhombencephalon (hindbrain).1 With the exception of the olfactory nerves (I), all cranial nerves are arrayed along the brainstem. Injury to the left side of the brain affects speech and movement on the right side of the body. 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. In most people, the left hemisphere regulates language and speech, and the right hemisphere controls nonverbal, spatial skills. The right hemisphere controls the left side of the body, and the left hemisphere controls the right side. It is located just above the brain stem and. The brain stem contains many nerves, pathways, reflex centers, and nuclei and serves as a major relay station for sensory, motor, and autonomic information. The brain has two halves or hemispheres: right and left. The cerebellum is involved in the coordination of voluntary motor movement, balance and equilibrium and muscle tone. The brain stem is a stalk-like structure that connects the cerebrum with the spinal cord and consists of the midbrain, pons, and medulla oblongata.
