The divisions of the nervous system Flashcards
central and peripheal (somatic and autonomic
1
Q
components of central nervous system
A
Spinal Cord and Brain
2
Q
components of peripheral nervous system
A
Autonomic and Somatic nervous system
3
Q
Components of the autonomic nervous
A
Parasympathetic and Sympathetic
4
Q
function of the brain
A
- The center of all conscious awareness
- The brain collects all the information provided by other areas of the nervous system and makes decisions based on this information
5
Q
function of the spinal cord
A
- An extension of the brain
- Responsible for our reflex actions
- Passes messages to and from the brain and connects nerves to the PNS
6
Q
peripheral nervous system
A
- makes up all the nerve cells outside of the brain and spinal cord
- relays nerve impulses from the CNS to the rest of the body and from the body back to the CNS
7
Q
somatic nervous system
A
- controls skeletal muscle movement
- receives information from the sensory neurons
- has motor neurons; helps complete reflex actions quickly to ensure minimal damage to our bodies
8
Q
autonomic nervous system
A
- governs vital functions in the body
- works on organs and glands and its control center can be found in the brain stem
9
Q
sympathetic nervous system
A
- activated once we are exposed to a stressors
- hypothalamus sends signals to the SNS and this in turn leads to the release of adrenal from the adrenal glands
10
Q
parasympathetic nervous system
A
- responsible for negating the effects of the sympathetic nervous system.
- inhibits the release of adrenaline, returning our body to a state of homeostasis
