|
Brain Stem |
Connects cerebrum to spinal cord and controls critical involuntary body functions |
|
Cerebellum |
Part of brain in charge of cordination of muscle control and balance Controls voluntary and involuntary movements |
|

|
Spinal Cord |
Transmits nerve impulses from the body extremities to the brain |
|
PNS |
Includes all nerves that exist outside the CNS Branches into somatic and autonomic |
|
Somatic Nervous System |
System that sends and receives signals from skeletal muscle |
|
Autonomic Nervous System |
Regulates body process the are not concious ( smooth and cardiac muscle and glandular secretions) |
|
Pons |
Contains nuclei that relay signals from the forebrain to cerebellum |
|
Midbrain |
Part of the brain that integrates sensory signals and organizes responses to these signals |

Stimulate muscle to move |
|
Midbrain |
Part of the brain that serves important functions in motor movement, particularly movements of the eye, and in auditory and visual processing. Simple: plays a role in motor movement and audio/visual processing |
|
hindbrain |
Part of the brain that coordinates functions that are fundamental to survival, including respiratory rhythm, motor activity, sleep, and wakefulness Involved with autonomic function |
