The peripheral nervous system is involved in both <u>voluntary and involuntary actions.</u>
Explanation:
The peripheral nervous system (PNS) is the neural system that resides outside the central nervous system (CNS). This contains nerves which in turn connect with the organs of the body like the sensory organs, glands, blood vessels, muscles etc with the central nervous system (CNS).
The PNS is divided into somatic and autonomic nervous systems. 
The somatic nervous system contains sensory and motor nerve fibers which send sensory information and controls motor functions respectively. The voluntary movements of skin, skeletal muscles, bones, and joints are controlled by somatic PNS.
The autonomic nervous system composed of sympathetic, parasympathetic and enteric nervous systems controls the involuntary actions of smooth muscles of the internal visceral organs.
