What is the study of muscles, including their structure and function?

Myology is the branch of anatomy that specifically focuses on the study of muscles, including their structure, function, and development. This field examines various aspects of muscles, such as their contraction, organization, and relationship with other body systems, enabling a comprehensive understanding of how muscles contribute to movement and overall body function.

The other options pertain to different areas of study that do not relate specifically to muscles. Osteology is the study of bones; pathology deals with diseases and their effects on the body; and histology examines the microscopic structure of tissues. Understanding these distinctions helps clarify the unique focus of myology within the broader context of medical and biological sciences.
