Anatomy and physiology of the brain

Usually this is because the fluid is not circulating properly. A pocket of infection in the brain, usually by bacteria. Information in the brain is stored in a few different ways depending on its source and how long it is needed.

Ventriculostomy is usually performed to relieve high brain pressures. In other parts of the body, endothelial cells have small spaces between them that allow substances to move in and out of the capillary so they can reach other cells and tissues.

The spinal nerves are numbered after nearby vertebrae. The superior sagittal sinus is a vein that runs through the longitudinal fissure of the brain and carries blood and cerebrospinal fluid from the brain back to the heart.

EEG can help diagnose seizures, or other brain problems. The cerebellum receives sensory inputs from the muscles and joints of the body and uses this information to keep the body balanced and to maintain posture.

Picture of the Brain

Vomiting, sneezing, coughing, and swallowing reflexes are coordinated in this region of the brain as well. Some of these hormones, such as oxytocin and antidiuretic hormone, are produced in the hypothalamus and stored in the posterior pituitary gland.

Swelling of the brain tissue in response to injury or electrolyte imbalances. The parietal lobe integrates sensory information and plays a role in spatial perception. The medulla contains mostly white matter that carries nerve signals ascending into the brain and descending into the spinal cord.

The other 10 pairs start in the brain stem.

Welcome to the Visible Body Blog! An abnormally increased amount of cerebrospinal brain fluid inside the skull. Thalamus The thalamus is a structure in the middle of the brain that has 2 lobes or sections. Bleeding between the tough tissue dura lining the inside of the skull and the skull itself, usually shortly after a head injury.

Textbook of Clinical Neurology, 3rd Edition, Saunders, Head injuries and strokes may cause epilepsy, but usually no cause is identified.

This space is called the subarachnoid space. Between the vertebrae are the discs intervertebral discs.

During REM sleep, the body becomes paralyzed while the eyes move back and forth quickly. Many of the most basic survival functions of the brain are controlled by the brainstem. Found between the pons and the diencephalon, the midbrain can be further subdivided into 2 main regions: The pons is the region of the brainstem found superior to the medulla oblongata, inferior to the midbrain, and anterior to the cerebellum.

Cranial nerves There are 12 pairs of cranial nerves that perform specific functions in the head and neck, including giving us our sense of smell, sight visionhearing, taste, speech, feeling in the face and movement of the muscles in the face, eyes and tongue.

Cerebrospinal Fluid Cerebrospinal fluid CSF — a clear fluid that surrounds the brain and spinal cord — provides many important functions to the central nervous system.The brain is a spongy organ made up of nerve and supportive tissues. It is located in the head and is protected by the boney covering called the skull.

The base or lower part of the brain is connected to the spinal cord. Together, the brain and spinal cord are known as the central nervous system (CN.

These vital structures are surrounded and protected by the bones of the skull and the vertebral column, as shown in the mint-body.com bones of the skull are often referred to as the cranium.

Your body, like a computer, is made up of tons of small wires (vasculature), parts (organs), and the tasks it performs come from the central processing unit, or CPU (brain).
