Evolution
Send information away from the central nervous system to control the muscles or glands.
(a)
(a) are the cells that send information between the motor neurons and the sensory neurons.
- activates to speed up your heart rate, deliver more blood to areas of your body that need more oxygen or other responses to help your get out of danger
- responding to dangerous or stressful situations.
Sympathetic Nervous system
Parasympathetic Nervous system
Central Nervous System
Peripheral nervous system
- it slows our heart and breathing rates, lowers blood pressure and promotes digestion. Our body enters a state of relaxation, and this relaxation breeds recovery.
