Three components of the brain

The skull is the bony framework of the head made up of 21 bones. The Midbrain The midbrain is located between the hindbrain and forebrain, but it is actually part of the brain stem.

From the fourth ventricle, CSF flows into the subarachnoid space where it bathes and cushions the brain. It plays a role in just about every major body system. This region also participates in our emotional reaction to pain and in the regulation of aggressive behavior.

Cortex The surface of the cerebrum is called the cortex. Pituitary gland: lies in a small pocket of bone at the skull base called the sella turcica.

Brain parts and functions

The brainstem continues below this as the spinal cord , [39] protected by the vertebral column. The amygdala: The figure shows the location of the amygdala from the underside ventral view of the human brain, with the front of the brain at the top of the image. The prefrontal cortex holds recent events briefly in short-term memory. Some of its main functions include: processing sensory information regulating blood pressure and breathing releasing hormones Anatomy and function Cerebrum The cerebrum is the largest part of the brain. It displays the same basic functional composition found in the spinal cord and the hindbrain. Memory Memory is a complex process that includes three phases: encoding deciding what information is important , storing, and recalling. The neurotransmitters travel across the synapse, carrying signals to other cells. Dorsal regions of the midbrain are involved in sensory information circuits.

The cortex contains neurons grey matterwhich are interconnected to other brain areas by axons white matter. The brain stem contains the pons and medulla oblongata.
