The correct option is Skeletal muscles.
Explanation
The Peripheral Neural System (PNS) is functionally divided into two major components based on the target organs they innervate: the somatic neural system and the autonomic neural system.
- Somatic Neural System: This division relays impulses from the Central Nervous System (CNS) to skeletal muscles. It is primarily responsible for voluntary control of body movements and the reception of external stimuli.
- Autonomic Neural System: This division transmits impulses from the CNS to involuntary organs and tissues. It regulates the functions of smooth muscles, cardiac muscles, and glands.
Therefore, skeletal muscles are the specific target of the somatic neural system, while smooth muscles, cardiac muscles, and glands are innervated by the autonomic neural system.
Key Takeaway: The somatic neural system connects the CNS to voluntary skeletal muscles, whereas the autonomic neural system connects the CNS to involuntary visceral organs, smooth muscles, and glands.
