MSDs involve which anatomical structures?

• A. Nerves, tendons, muscles, and supporting structures
• B. Bones only
• C. Blood vessels only
• D. Skin and fat cells

Answer: (A)

Musculoskeletal disorders involve the tissues that move and support the body: muscles generate force, tendons transmit that force to bones, nerves control muscle action and sensation, and supporting structures like ligaments, fascia, and joint capsules help maintain stability and alignment. This combination captures the common sites and tissues affected by MSDs, from tendinopathies and muscle strains to nerve compression. Bones are part of the system, but focusing on bones alone misses the critical soft tissues involved. Skin and fat cells are not part of the musculoskeletal system, and blood vessels, while important for tissue health, don’t define MSDs by themselves.
