The |cerebrum| is descriptively divided into four section, or |lobes|, named for the cranial bones which they are nearest: the frontal |lobe|, the occipital |lobe|, the parietal |lobe|, and the temporal |lobe|. Cerebrospinal fluid, used to support the |brain| and buffer it, is transmitted to these |lobes| by means of |lateral ventricles| which project branches, or horns (cornu), into the frontal, occipital, and temporal |lobes|. The functions of each |lobe| are coordinated by connecting, or commissural, |fibers|. The frontal |lobe| is located behind the |frontal bone| and is responsible for voluntary motor coordination. It houses control areas for muscular control of the body and for coordinated rhythmical movements of the head and throat, such as in chewing, licking, and swallowing. The frontal |lobe| also contains the higher thought processing centers of memory, reasoning, and associative conceptualizing. The occipital |lobe| is located just in front of the |occipital bone| and contains the centers responsible for sight. Damage to the occipital |lobe| therefore often results in |vision impairment|. The parietal |lobe| is located in the upper, middle part of the |brain|, next to the |parietal bones|. It houses the control centers for processing impulses related to the sense of touch. Temperature, texture, size, shape, and weight are analyzed and processed here. The temporal |lobe| is located on the side of each ~hemisphere~ of the |brain|, next to the |temporal bone|, and houses areas for the processing and correlation of auditory (hearing) and olfactory (smell) senses. Damage to this section of the |brain| can result in deafness, auditory hallucinations, and other hearing disorders.
