What does the peripheral nervous system (PNS) consist The peripheral nervous system (PNS) consists of all nervous tissue outside the
of? CNS, including sensory and motor neurons
Somatic Nervous System (SNS): The somatic nervous system (SNS) controls voluntary movements by activating
- Functions skeletal muscles
Autonomic Nervous System (ANS): The autonomic nervous system (ANS) controls involuntary responses by
- Functions influencing organs, glands, and smooth muscle
, Parasympathetic Division: - Constricts pupils (miosis)
- "Rest and digestion"
- Stimulates salivation
- Slow heart rate, contractility
- Constricts bronchioles
- Stimulates digestion
