THE BRAIN
Source
The brain is one of the largest and most complex organs in the human body.it is up to more than 100 billion nerves that communicate in trillions of connections called synapses.

The brain is made up of many specialized areas that work together.

•The cortex is the outermost layer of the brain cells. thinking and voluntary movement begin in the context.
The brain stem is between the spinal cord and the rest of the brain. Basic functions like breathing and sleep are controlled here.
•The basal ganglia is a cluster of structures in the center of the brain. the ganglia coordinate messages between multiple other brain areas.
•The cerebellum is at the base and the back of the brain. The cerebellum is responsible for coordination and balance.

The brain is divided into several lobes.
•The frontal lobes are responsible for problem-solving and judgment and motor function.
•The parietal lobes manage sensation, handwriting, and body position.
•The temporal lobes are involved with memory and hearing.
•The occipital lobes contain the brain's visual processing system.

the brain is surrounded by a layer of tissue called the meninges the skull (cranium) helps protect the brain from injury.

BRAIN CONDITION

HEADACHE: there are many types of headache; songs can serious but most are not and are generally treated with analgesic/painkiller.
STROKE (brain infection): blood flow and oxygen are suddenly interrupted to an area of brain tissue which then dies. a blood clot or bleeding in the brain; is the cause of most strokes.
BRAIN ANEURYSM: an artery in the brain develops a weak area that swells, ballon like a brain aneurysm causea brain stroke.
BRAIN TUMOR: any abnormal tissue growth inside the brain whether malignant (Cancer)or Benign, brain tumor usually
causes problems by the pressure that exerts on the normal brain.

BRAIN TESTS

•Computed tomography( CT scan) a scanner that takes multiple x-rays which a computer converts into detailed images of the brain and skull.
•Magnetic resonance imaging(MRI scan) using radio waves in a magnetic field, an MRI scanner creates highly detailed images of the brain and other parts of the head.

BRAIN TREATMENT

•ANTIBIOTICS: when a brain infection is caused by bacteria, antibiotics that kill the organism and make a cure more likely.
•BRAIN SURGERY: an operation on the brain can cure some brain tumor. brain surgery may be performed anytime increased. pressure in the brain threatens brain tissues.
