3 Functions:
General Functions of the Nervous
SystemMaster Controlling and Communicating System in the body
3 Functions:
1. Monitor changes inside and outside the body (sensory input- gathering info.)
General Functions of the Nervous
SystemMaster Controlling and Communicating System in the body
3 Functions:
1. Monitor changes inside and outside the body (sensory input- gathering info.)
2. Processes information and makes decisions – called integration
General Functions of the Nervous
SystemMaster Controlling and Communicating System in the body
3 Functions:
1. Monitor changes inside and outside the body (sensory input- gathering info.)
2. Processes information and makes decisions – called integration
3. Motor output (motor=muscle) response by activating glands or muscles
Divisions of the Nervous System
Peripheral Nervous System Central Nervous System (CNS)
Divisions of the Nervous System
Peripheral Nervous System Central Nervous System (CNS)
Parts: brain and spinal cord
Divisions of the Nervous System
Peripheral Nervous System Central Nervous System (CNS)
Parts: brain and spinal cord
Functions:
1. Body’s control system
Divisions of the Nervous System
Peripheral Nervous System Central Nervous System (CNS)
Parts: brain and spinal cord
Functions:
1. Body’s control system
2. Receives sensory input
3. Relays motor impulse via efferent nerves
Divisions of the Nervous System
Peripheral Nervous System Central Nervous System (CNS)
Parts: brain and spinal cord
Functions:
1. Body’s control system
2. Receives sensory input
3. Relays motor impulse via efferent nerves
4. Center for higher function- intelligence, memory, emotion
Divisions of the Nervous System
Peripheral Nervous System
Parts: nerves outside the CNS
Central Nervous System (CNS)
Divisions of the Nervous System
Peripheral Nervous System
Parts: nerves outside the CNS
Function:
1. Sensory- nerves to CNS (afferent). Carries impulses from receptors to CNS.

Peripheral Nervous System
Parts: nerves outside the CNS
Function:
1. Sensory- nerves to CNS (afferent). Carries impulses from receptors to CNS.
2. Motor (efferent) nerves from CNS to effector. Carries impulses from CNS to effector (muscles or glands).

Divisions of the motor system
1. Somatic Nervous System
Voluntary- afferent nerves from skin and muscles go to CNS. Efferent nerves from CNS to skeletal muscles.

1. Somatic Nervous System
Voluntary- afferent nerves from skin and muscles go to CNS. Efferent nerves from CNS to skeletal muscles.
2. Autonomic Nervous System
Involuntary- afferent nerves are from internal organs to CNS. Efferent nerves from CNS to cardiac or smooth muscles.
