nervous
The somatic nervous system issues somatic motor commands that control voluntary muscle movements in the body. These commands are sent from the central nervous system to skeletal muscles, allowing for purposeful physical actions such as walking, reaching, and speaking.
motor unit
A motor neuron and all of the skeletal muscle cells it stimulates together form a motor unit. The motor neuron sends signals to the muscle cells to contract and produce movement. Each motor unit typically controls multiple muscle cells to allow for coordinated and efficient movement.
The stimulus that travels from the motor neuron to skeletal muscle is an electrical signal called an action potential. This action potential causes the release of neurotransmitters, specifically acetylcholine, which then stimulates muscle contraction.
The skeletal system provides structural support for the body, protects internal organs, allows for movement through its joints, and stores minerals such as calcium and phosphorus for bodily functions.

There are no organs in the skeletal system. The skeletal system is comprised of the bone structure of an organism; i.e. metatarsals, cranium etc.

Nope, They are a tubular organism with no skeletal structure
