Final answer:
The interaction of the skeletal and muscular systems to create movement and locomotion is regulated by the nervous system. The nervous system sends signals from the brain to the muscles, instructing them to contract or relax, which allows for movement. It also receives feedback from sensory receptors in the muscles and joints to help maintain balance and coordinate movements.
Step-by-step explanation:
The interaction of the skeletal and muscular systems to create movement and locomotion is regulated by the nervous system. The nervous system sends signals from the brain to the muscles, instructing them to contract or relax, which allows for movement. It also receives feedback from sensory receptors in the muscles and joints to help maintain balance and coordinate movements.
For example, when you decide to walk, the brain sends signals to the muscles in your legs to contract and move your limbs in a coordinated manner. If you step on an uneven surface, sensory receptors in your feet send signals to the brain, which then adjusts the muscle contractions to maintain balance.
