What is the peripheral nervous system?
Consists of the nerves and has two divisions, the somat nervous system and automatic nervous system.
What is the thalamus?
Acts as a relay center and directs sensory impulses to the cerebrum.
What is the brain?

What is diencephalon?
The section located between the cerebrum and midbrain.
What are the nerves?
A combination of many nerve fibers located outside the brain and spinal cord.
