Study Notes
Peripheral Nervous System
- The peripheral nervous system (PNS) is outside the brain and spinal cord
- It carries impulses from sensory nerves to the central nervous system (CNS) and from the CNS to motor nerves
- The PNS can be divided into two parts: the sensory division and the motor division
- The sensory division transmits impulses from sensory organs (e.g., ears, eyes, nose) to the CNS
- The motor division transmits impulses from the CNS to muscles or glands (effectors)
Somatic Nervous System
- Includes all nerves that control muscles which are under conscious control
- Regulates activities involving sensory receptors, muscles and glands
- Examples of activities include moving fingers, wiggling toes, and activities involving the salivary and gastric glands.
Autonomic Nervous System
- Consists of motor neurons that control internal organs
- Regulates involuntary activities of the body.
- The autonomic nervous system is subdivided further into the sympathetic and parasympathetic nervous systems.
Sympathetic Nervous System
- Dilates pupils
- Inhibits salivation
- Relaxes bronchi
- Accelerates heartbeat
- Inhibits digestive activity
- Stimulates glucose released by liver
- Relaxes bladder
Parasympathetic Nervous System
- Contracts pupils
- Stimulates salivation
- Contracts bronchi
- Slows heartbeat
- Stimulates digestive activity
- Stimulates gallbladder

- Shows a diagram of the autonomic nervous system.
