Final answer:
Body movement is an example of how the skeletal and neuromuscular systems work together, as muscles contract to move the bones of the skeleton.
Step-by-step explanation:
The question refers to the example of how the skeletal and neuromuscular systems work together. The correct answer to this question is a. body movement. This is because the bones of the skeletal system provide structure and support for the body, while the muscles of the muscular system contract and pull on the bones, facilitating the body to move.
Functions such as standing, walking, running, and grasping items are all direct results of the cooperative functionality of the skeletal and muscular systems.
