Nervous System

By Jacob Scandalis

Function of the Nervous System

Controls movement of the body and communicates with the other systems.

Central Nervous System and Peripheral Nervous System.

Central Nervous System: Nerve tissues that control the activities of the body. Comprises of the Brain and Spinal Cord.

Peripheral Nervous System: Nervous system outside of the Brain and Spinal Cord.

Functions of The Cerebral Hemisphere, Diencephalon, Brain Stem and Cerebellum

Cerebral Hemisphere - the functions of the fontal, parietal, temporal, and occipital lobes of the cerebral cortex, differentiate between the lateralized functions of the left and right hemispheres of the brain, locating the processes of language, logical reasoning, and various perceptual tasks.

Diencephalon - the region of the embryonic vertebrate neural tube that gives rise to posterior forebrain structures including the thalamus, hypothalamus, posterior portion of the pituitary gland, and pineal gland.

Brain Stem - Regulation of heart rate, breathing, sleeping, and eating.

Cerebellum - Receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. Also coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth, balanced muscular activity.

2 Major Disorders

Brain Tumor - Headaches, which may be severe and may worsen with activity or in the early morning seizures. Motor seizures, also called convulsions, are sudden involuntary movements of a person’s muscles. People may experience different types of seizures, including mycologic and tonic-clonic. Certain drugs can help prevent or control them. Treatments are years of surgeries.

Epilepsy - Epilepsy is a group of related disorders characterized by a tendency for recurrent seizures. There are different types of epilepsy and seizures. Epilepsy drugs are prescribed to control seizures, and rarely surgery is necessary if medications are ineffective.
