What parts of the body can be affected by musculoskeletal disorders?

Musculoskeletal disorders primarily affect muscles, nerves, blood vessels, ligaments, and tendons. These disorders can arise from various factors, including repetitive motions, awkward postures, and excessive force applied during tasks. The involvement of muscles is significant since they are responsible for movement and stability. Ligaments and tendons connect muscles to bones and bones to other structures, respectively, playing a crucial role in joint stability and mobility.

Nerves are also affected, as they transmit signals between the brain and the muscles for proper functioning and coordination. Disorders in this area can lead to conditions such as carpal tunnel syndrome or tendonitis, which result in pain and decreased function. Blood vessels are included as well since poor circulation can exacerbate musculoskeletal issues and lead to further complications.

In contrast, the other choices focus on body parts that are not primarily involved in musculoskeletal disorders. For example, teeth and gums pertain to dental health, while skin and hair relate more to dermatological conditions. Lastly, eyes and ears concern sensory functions rather than physical strain or injury related to musculoskeletal activities. Hence, the correct answer encompasses the body parts most associated with musculoskeletal disorders and their implications for physical health.
