Final answer:
The somatic nervous system is involved when forming guitar chords, coordinating messages from the brain to the motor neurons in the hands. It is part of the broader nervous system, which includes the central and peripheral systems, and is responsible for both voluntary and involuntary actions.
Step-by-step explanation:
Forming guitar chords for the first time involves messages sent from your brain to your fingers via the somatic nervous system. This part of your nervous system carries messages that control body movements, and it is responsible for activities that are under your control, such as moving your hands to form guitar chords. As a student learns how to form these chords, their brain sends messages to motor neurons, which control the muscles in their hands, allowing for the precise movement needed to play music.
In addition to motor skills, the nervous system includes the brain and spinal cord, which constitute the central nervous system, as well as nerves throughout the body making up the peripheral nervous system. Messages within this system travel quickly to coordinate various bodily actions and responses, including the voluntary movements of our muscles as well as involuntary reactions and reflexes.
