The Three main functions of the Nervous System are... |
Sensory Input, Integration, and Motor Output
|
|
|
Receptors within and near the body surface respond to stimuli and send nerve impulses to the CNS. |
Sensory Input
|
|
|
The CNS receives, processes and interprets sensory input and decides what to do via sensory output. |
Integration
|
|
|
CNS sends out impulses to effector organs (muscles and glands) in response to sensory output. |
Motor output
|
|
|
-Brain and Spinal cord -tracts -integrative and communicative centers -sends impulses to peripheral nervous system |
Central Nervous System
|
|
|
-Cranial and Spinal nerves -Communication between CNS and body |
Peripheral Nervous System
|
|
|
Divisions of the Peripheral Nervous System
|
Sensory (Afferent) Division Motor (Efferent) Division |
|
|
Conducts impulses from receptors to CNS |
Afferent Nerve
|
|
|
Nerve fibers that conduct impulses from the CNS to Skeletal muscles. Division of Peripheral Nervous System. Composed of Somatic motor fibers. |
Somatic Nervous System
|
|
|
Division of Peripheral Nervous System, consists of visceral motor nerve fibers that regulate smooth muscle, cardiac muscle, and glands. |
Autonomic Nervous System
