Terms to Know
Blood-Brain Barrier

A barrier created by glial cells called astrocytes; the blood-brain-barrier only allows a small amount of materials from the blood to enter the inside of the brain. It plays a role in protecting neurons and creating a stable environment inside of the brain.

Cerebral Spinal Fluid

A fluid similar to plasma that is created by the brain; it washes the brain of metabolic waste and plays a minor role in cushioning the brain.

Forebrain

The largest part of the brain that consists of the cerebral hemispheres and all of the structures contained within them.

Hindbrain

The area of the brain that consists of the cerebellum, pons, and medulla oblongata.

Meninges

The protective connective tissue found on the outside of the brain and spinal cord; consists of three layers: dura mater, arachnoid mater, pia mater.

Midbrain

The area of the brain that connects the hindbrain to the forebrain; also the top structure of the brain stem.
