Objectives 31.3 The Peripheral Nervous System -Describe the functions of the sensory division of the peripheral nervous system. -Describe the functions of the motor division of the peripheral nervous system.

The Peripheral Nervous System The peripheral nervous system consists of all the nerves and associated cells that are NOT part of the brain or spinal cord.

The Sensory Division The sensory division of the peripheral nervous system transmits impulses from sense organs to the CNS.

Sensory receptors are categorized by the type of stimuli to which they respond.

The Motor Division The motor division of the peripheral nervous system transmits impulses from the central nervous system to muscles or glands.

Somatic Nervous System The somatic nervous system regulates body activities that are under conscious control, such as the movement of skeletal muscles.

Reflex Arcs The somatic nervous system also controls your reflex responses. For example, if you accidentally step on a tack with your bare foot, your leg may recoil before you are even aware of the pain. This rapid response (a reflex) is caused by impulses that travel a pathway known as a reflex arc.

Autonomic Nervous System The autonomic nervous system regulates activities that are involuntary, or not under conscious control.

Autonomic Nervous System The autonomic nervous system consists of two parts, the sympathetic nervous system and the parasympathetic nervous system. In general, the sympathetic and parasympathetic systems have opposite effects on each organ they influence. Heart rate is increased by the sympathetic nervous system but decreased by the parasympathetic nervous system.
