The lobes of the brain were originally a purely anatomical classification, but have been shown also to be related to different brain functions. The cerebrum, the. Identify the location and function of the lobes of the brain The cerebral cortex, which is the outer surface of the brain, is associated with higher level processes. Lobes and Functional Areas of the Brain. 1. parietal lobe. 2. frontal lobe. 3. temporal lobe – auditory cortex. 4. occipital lobe – visual cortex. 5. insula. Sulci, Gyri.

Miraculously, Gage survived, blinded in his left eye and sustaining damage to much of his left frontal lobe. The frontal lobe also contains the primary motor cortex, the major region responsible for voluntary movement.
InPhineas Gage survived an explosion that drove a tamping iron through his left frontal lobe. Areas in the parietal lobe are responsible for integrating sensory information, including touch, temperature, pressure and pain.

Because of the processing that occurs in the parietal lobe, we are able to, for example, discern from touch alone that two objects touching the skin at nearby points are distinct, rather than one object.
This process is called two-point discrimination. Several areas of the parietal lobe are important in language processing. The somatosensory cortex can be illustrated as a distorted figure — the homunculus Latin: A lesion commonly brain lobes and functions the right superior or inferior parietal lobule leads to hemineglect.
Skill memory is processed in the cerebellum, which relays information to the basal brain lobes and functions.
It stores automatic learned brain lobes and functions like tying a shoe, playing an instrument, or riding a bike. Ventricles and cerebrospinal fluid The brain has hollow fluid-filled cavities called ventricles Fig. Inside the ventricles is a ribbon-like structure called the choroid plexus that makes clear colorless cerebrospinal fluid CSF.
CSF flows within and around the brain and spinal cord to help cushion it from injury.

This circulating fluid is constantly being absorbed and replenished. CSF is produced inside the ventricles deep within the brain.

- Parietal lobe
CSF fluid circulates inside the brain and spinal cord and then outside to the subarachnoid space. Common sites of obstruction: There are two ventricles deep within the cerebral hemispheres called brain lobes and functions lateral ventricles.

They both connect with the third ventricle through a separate opening called the foramen of Monro. The third ventricle connects with the fourth ventricle through a long narrow tube called the aqueduct of Sylvius.
From the fourth ventricle, CSF flows into the subarachnoid space where it bathes and cushions the brain. Brain lobes and functions is recycled or absorbed by special structures in the superior sagittal sinus called arachnoid villi.
brain lobes and functions A balance is maintained between the amount of CSF that is absorbed and the amount that is produced. A disruption or blockage in the system can cause a build up of CSF, which can cause enlargement of the ventricles hydrocephalus or cause a collection of fluid in the spinal cord syringomyelia.
Skull The purpose of the bony skull is to protect the brain lobes and functions from injury. The skull is formed from 8 bones that fuse together along suture lines. These bones include the frontal, parietal 2temporal 2sphenoid, occipital and ethmoid Fig.

The face is formed from 14 paired bones including the maxilla, zygoma, nasal, palatine, lacrimal, inferior nasal conchae, mandible, and vomer. The brain is protected inside the skull. The skull is formed from eight brain lobes and functions.
