Parts and Functions of Our Brains

Bark (Brain)
Cortex, or brain, consists of two hemispheres (or wall) connected to the band of tissue called the corpus callosum. These hemispheres control speech, intelligence and memory. There are special centers for specific functions such as call center governs the ability to create sounds in words meaning, expressions, etc.

Left Hemisphere
The left hemisphere "on the right side of the body. It controls speech, comprehension, arithmetic, and writing.

Right Hemisphere
The right hemisphere controls the left side of the body. He is responsible for more abstract skills such as creativity, spatial ability and artistic and musical skills.

Each hemisphere is divided into lobes. (In this example, the frontal lobe, temporal lobe, parietal lobe, occipital lobe, sensory motor and the Gaza Strip are the parts that make up the cortex).

Frontal Lobe
Frontal lobe is in front of the brain behind the forehead. It is the center of the sentence, reasoning, personality, motivation and inhibition of impulses. It also plays a role in controlling emotions, social skills and expressive language.

Parietal Lobe
Parietal lobe is located just behind the frontal lobe. He is responsible for receiving and processing of sensations of touch (eg, pain, heat, cold, pressure, size, shape and texture). Analyze information in conjunction with the five senses. It is also closely associated with the writing and the mastery of speech.

Temporal Lobe
Temporal lobe is located next to the frontal and parietal lobes, just above the ear. It is the center of hearing, taste and smell. He is also involved in obtaining information and auditory memory.

Occipital Lobe
Occipital lobe is located behind the parietal and temporal cortex. Damage in this area can affect vision, such as perception and understanding of visual information.

Cerebellum is located below the cerebral cortex at the back of the skull. Is smaller than the bark. Its task is to communicate and coordinate the signals from the cortex. also controls voluntary muscle movement, balance, posture and movement coordination.

Brainstem is the cerebellum and cerebral cortex. It connects the spinal cord to the cerebral cortex. Its role is to transmit messages back and forth between different parts of the body and the cerebral cortex.

Brainstem coordinates bodily functions such as breathing, blood pressure and pulse. It also contains the reticular formation, which is responsible for consciousness, drowsiness and attention. Brainstem is 12 cranial nerves.

These nerves control smell, hearing, vision, eye movement, facial sensations, taste and swallowing. Controlling the movements of facial muscles, neck, shoulders, and tongue.

Damage to one of these areas can have an impact on the areas it controls. However, there are no two similar injuries. It is important to note that all sectors will be affected, brain damage can be localized and very specific areas may be limited. Above is only for a brief overview of the different areas of the brain and control. It is impossible to generalize, which relate to the control centers in the survival of brain damage, without a large number of medical observation and long term.
