FUNCTIONS OF THE CNS

3 broad functions of the CNS: take in sensory information, process information, send out motor signals.

Cerebrum is the part of your brain that starts and manages conscious thoughts.

Cerebrum is the largest region and the most noticeable part of the human brain which makes up the 85 percent of the human brain.

Peripheral Nervous System plays a key role in both sending information from different areas of your body back to your brain, as well as carrying out commands from your brain to various parts of your body.

The Limbic System is responsible for explaining why sexual activities and eating activities are pleasurable or why mental stress can cause high blood pressure.

The Thalamus acts as a gateway and it receives sensory and motor inputs from the body, except smell, and receives feedback from the cortex.

The Sympathetic Nervous System prepares the body for "fight and flight" response.

Brain Stem is the structure that connects the cerebrum of the brain to the spinal cord and cerebellum.

The Autonomic Nervous System controls involuntary bodily functions and regulates glands, directs motor nerve fibers in smooth muscles, cardiac muscles, lungs, and the exocrine and endocrine glands.

Cerebellum means "little brain." Your cerebellum is only about 10% of your brain in terms of how much space it takes up.
