Two divisions of the nervous system?
Central Nervous System (CNS) and Peripheral Nervous System (PNS)
Composed of the brain and spinal cord to control all body actions?
Central Nervous System
Composed of sensory and motor nerves and sense organs that will carry messages to and from the CNS?
Peripheral Nervous System
The two divisions of the Peripheral Nervous System?
Somatic Nervous System and Autonomic Nervous System
Controls voluntary functions such as walking and talking?
Somatic Nervous System
Controls involuntary functions like breathing, digestions, and heart beat?
Autonomic Nervous System
Two divisions of the autonomic nervous system?
Sympathetic and Parasympathetic
Responsible for fight or flight response (vasoconstriction - accelerated heart rate constricted blood vessels, blood pressure rises)?
Sympathetic Nervous System
Returns the body to normal or rest and digest response (vasodilation - slow heart rate, dilate blood vessels, lowers BP)?
Parasympathetic Nervous System
