Musculoskeletal Anatomy Review

Which of the following is NOT a benefit of building a strong musculoskeletal system?

• Reduced risk of injuries

• Decreased risk of osteoporosis

• Reduced incidence of low-back problems

• Decreased performance

Which of the following describes how muscles and bones work together to create movement?

• Muscles are attached to bones by tendons. When a muscle contracts, it pulls on the bone, causing bending at a joint. To reverse the action at the joint, contraction of an opposing group of muscles occurs.

• Muscles are attached to bones by ligaments. When a muscle contracts, it pulls on the bone, causing bending at a joint. To reverse the action at the joint, contraction of an opposing group of muscles occurs.

• Muscles are attached to bones by tendons. When a muscle contracts, it pulls on the bone, causing bending at a joint. To reverse the action at the joint, the same muscle group extends, causing movement in the opposite direction.

Which of the following is NOT an example of opposing muscle groups used to create movement of the musculoskeletal system?

• Biceps & triceps muscles at the elbow joint

• Quadriceps & hamstring muscles at the knee joint

• Deltoids and pectoral muscles of the wrists

• Anterior tibialis & gastrocnemius muscles at the ankle joint

True or false? Weight-bearing activities improve bone density by adding stress where muscles attach to bones, which causes the bones to adapt and become more dense and stronger.
