HOMEOSTASIS |
The maintenance of balanced internal physiological levels in the body |
|
|
|
STRUCTURE OF NERVOUS SYSTEM |
Nervous System --> Central Nervous System --------->Brain --------->Spinal Cord --> Peripheral Nervous System --------->Somatic --------->Autonomic ---------------->Sympathetic ---------------->Parasympathetic
|
|
|
|
FUNCTION OF CENTRAL NERVOUS SYSTEM |
-Processes sensory info & sends out motor impulses -Consists of the brain and spinal cord |
|
|
|
4 MAIN COMPONENTS OF THE NERVOUS SYSTEM |
Brain Nerves (including spine) Neurons Sensory receptors |
|
|
|
FUNCTION OF PERIPHERAL NERVOUS SYSTEM |
Consists of all Neurons outside of CNS Carries impulses to and from the CNS |
|
|
|
FUNCTION OF BRAIN |
-interpretation -thought -problem solving |
|
|
|
FUNCTION OF THE SPINAL CORD |
Links brain to PNS |
|
|
|
FUNCTION OF SOMATIC NERVOUS SYSTEM |
Deals with VOLUNTARY actions under conscious control
Relays information to and from skin and skeletal muscles under your conscious control |
Behaviour Intelligence Interpret sensory Initiate motor |
|
|
FUNCTION OF THE AUTONOMIC NERVOUS SYSTEM |
INVOLUNTARY relays information to your organs not under conscious control |
|
|
|
FUNCTION OF SYMPATHETIC NERVOUS SYSTEM |
"Fight or flight" Controls organs in time of stress |
|
|
|
FUNCTION OF PARASYMPATHETIC NERVOUS SYSTEM |
Controls organs when body is at rest Promotes normal body functioning (ie. Slows heartbeat after emergency has passed) |
|
|
|
3 MAJOR PARTS OF BRAIN |
- Cerebrum - Cerebellum - Mendulla Oblongata |
|
|
|
CEREBRUM |
-Largest part of the brain -Complex behaviour & intelligence, interpret sensory information, initiate motor impulses -Divided into right and left hemispheres. (Nerve fibres join at corpus callosum) -Cerebral cortex - highly folded outer surface.
|
|
|
|
CEREBELLUM |
-Found in hind brain -Controls all VOLUNTARY movement |
|
|
|
MEDULLA OBLNGATA |
-Connects spinal cord to brain (under cerebellum) -Controls involuntary activities (breathing heartbeat etc) |
|
