Final answer:
The statement that lean body mass includes muscles, bones, and non-fat tissues is true, reflecting their collective role in body structure, movement, and function.
Step-by-step explanation:
The statement about lean body mass including muscle, bone, and non-fat body tissue is true. Lean body mass indeed comprises muscle tissue, bone tissue, and other non-fat tissues such as organs and tendons. These components are essential in the overall structure and function of the human body, facilitating mobility, structural integrity, and vital bodily processes.
Muscle tissue is made up of cells that can contract and enable the body to move. Bones are living tissues that contain cells and can indeed affect processes in other parts of the body by producing hormones like osteocalcin. Sexual dimorphism is a concept that denotes the differences in skeleton structure between males and females; for example, females generally have wider pelvises to aid in childbirth. Skeletal muscles are attached to bones via tendons, which are made of strong connective tissue, allowing for movement when these muscles contract.
