The human brain

It plays a role in just about every major body system. Some of its main functions include:

The human brain

Next The brain is one of the largest and most complex organs in the human body. It is made up of more than billion nerves that communicate in trillions of connections called synapses. The brain is made up of many specialized areas that work together: Thinking and voluntary movements begin in the cortex.

The brain is also divided into several lobes: The brain is surrounded by a layer of tissue called the meninges.

The skull cranium helps protect the brain from injury.

A blood clot, or bleeding in the brain, are the cause of most strokes. An artery in the brain develops a weak area that swells, balloon-like. A brain aneurysm rupture can causes a stroke.

Bleeding within or under the dura, the lining inside of the skull. A subdural hematoma may exert pressure on the brain, causing neurological problems. Bleeding between the tough tissue dura lining the inside of the skull and the skull itself, usually shortly after a head injury.

Initial mild symptoms can progress rapidly to unconsciousness and death, if untreated.

Any bleeding inside the brain. A brain injury that causes a temporary disturbance in brain function. Traumatic head injuries cause most concussions.

Swelling of the brain tissue in response to injury or electrolyte imbalances. Any abnormal tissue growth inside the brain. Whether malignant cancer or benign, brain tumors usually cause problems by the pressure they exert on the normal brain.

An aggressive, malignant brain tumor cancer. Brain glioblastomas progress rapidly and are very difficult to cure. An abnormally increased amount of cerebrospinal brain fluid inside the skull. Usually this is because the fluid is not circulating properly. A form of hydrocephalus that often causes problems walking, along with dementia and urinary incontinence.The largest region of the human brain, our cerebrum controls higher brain functions such as language, logic, reasoning, and creativity.

The cerebrum surrounds the diencephalon and is located superior to the cerebellum and brainstem.

Anatomy of the Brain

The largest region of the human brain, our cerebrum controls higher brain functions such as language, logic, reasoning, and creativity. The cerebrum surrounds the diencephalon and is located superior to the cerebellum and brainstem. The brain constitutes only about 2 percent of the human body, yet it is responsible for all of the body's functions.

Learn about the parts of the human brain, as well as its unique defenses, like. The human brain is the center of the central nervous system in humans as well as the primary control center for the peripheral nervous system.

The brain controls "lower" or involuntary activities. The brain is an organ that’s made up of a large mass of nerve tissue that’s protected within the skull.

It plays a role in just about every major body system. The cerebrum is the largest part. Every animal you can think of -- mammals, birds, reptiles, fish, amphibians -- has a brain. But the human brain is unique. Although it's not the largest, it gives us the power to speak, imagine and problem solve.
