AFFERENT SYSTEM
|
-(ascending) sensory nerve that convey info from receptors within the skin, skeletal muscle or organ to the CNS
|
|
|
EFFERENT
|
-(descending) motor nerves that convey info from the CNS to the muscles (skeletal, smooth, and cardiac) and glands

|
SOMATIC NERVOUS SYSTEM
|
-efferent nerves that conduct impulses to skeletal muscle tissue,
-under conscious control (voluntary) |
|
|
AUTONOMIC NERVOUS SYSTEM
|
-efferent nerves that conduct impulses to smooth muscle tissue, cardiac muscle tissue and glands
-not under conscious control=voluntary -sympathetic nervous system -autonomic nervous system |
|
|
SYMPATHETIC DIVISION
|
-generally catabolic
- energy-expending that enables the body to deal with stress (flight of fight responses) |
|
|
PARASYMPATHETIC NERVOUS SYSTEM
