The brain has three sections on three different levels, from the top to the brain- stem, which form a unit.
There are three parts of the brain: cerebrum, cerebellum, and I can't remember the last one.
The cerebellum is also sometimes called the "Little Brain" or the brain within the brain.
The central nervous system is the brain and spinal cord. The branches from the brain and cord are called the peripheral nervous system.
The fluid filled spaces in the brain are called ventricles. The fluid is called cerebrospinal fluid
The ventricles are fluid filled cavities of the brain.
Axon terminals
Within the nervous system. The brain is obviously packed full of them, whilst the spinal cord and all extending peripheral branches are a network of nerve cells to carry signals between the brain and body.
interneurons also called central or association neurons
cerebrum
There are organs within any system but no systems within an other system. The nervous systems has the brain, the mid brain, the hind brain, the cord and the nerves.
