Final answer:
Muscle physiology is the study of how muscles work, encompassing the different types of muscle tissue and encompassing their structure, function, and interaction with other physiological systems.
Step-by-step explanation:
“Muscle physiology” is the study of how muscles work. Muscle physiology falls under the broader field of human physiology, which is concerned with the chemistry and physics of the body's structures and their functions, including homeostasis. The study of muscle physiology involves understanding the different types of muscle tissue—skeletal, cardiac, and smooth—and their roles in body movement and function.
The chapter on the Muscular System addresses muscle structure and function, describing how muscles contract based on the sliding filament theory, the effects of exercise on muscle fitness and health, and the diagnosis and treatment of various musculoskeletal and neuromuscular disorders.
Thus, within the context given, the correct answer to the question is that “Muscle physiology” is the study of how muscles work.
