Anatomy Practice Exam

Which of the following is a function of the muscular system?

1. Produces hormones for metabolic regulation

2. Aids in fluid balance and detoxification

3. Allows manipulation of the environment and locomotion

4. Serves as a protective barrier against pathogens

The correct answer is: Allows manipulation of the environment and locomotion

The muscular system plays a crucial role in enabling movement and interaction with the environment, which is why the correct answer focuses on its function in locomotion and manipulation. Muscles contract in response to neural signals, allowing the body to perform various movements such as walking, running, and jumping. This capability is essential for activities ranging from basic tasks to complex maneuvers, making the muscular system vital for overall mobility and functionality. The ability to manipulate the environment includes fine motor skills, such as grasping objects, as well as larger movements, such as climbing or throwing. The coordination of different muscle groups and the integration with the nervous system facilitate these actions. Thus, one of the primary and most recognizable functions of the muscular system is indeed its involvement in locomotion and manipulation of objects in our surroundings.
