Question 1

The sternoclavicular joint connects the clavicle to the scapula.

Accepted Answer

The sternoclavicular joint connects the clavicle to the sternum, not the scapula.

Question 2

The shape of the acromion could contribute to a rotator cuff injury.

Accepted Answer

The shape of the acromion can cause impingement on the rotator cuff tendons, leading to injury over time.

Question 3

Intervertebral discs act as shock absorbers and keep the spine flexible.

Accepted Answer

Intervertebral discs are located between the vertebrae of the spine and help to cushion and absorb shock as well as maintain flexibility in the spine.

Question 4

When the annulus ruptures and the nucleus pushes out of the intervertebral disc, this is referred to as a bulging disc.

Accepted Answer

When the annulus ruptures and the nucleus pushes out of the intervertebral disc, this is referred to as a herniated or slipped disc, not a bulging disc.

Question 5

The range of motion in exercises such as squats should be limited during a hamstring injury.

Accepted Answer

Limiting the range of motion in exercises such as squats can help prevent further damage to the hamstring and assist in the healing process.

Question 6

Tendinitis refers to the overstretching of a ligament.

Accepted Answer

Tendinitis refers to the inflammation or irritation of a tendon, not a ligament.

Question 7

Men are two to eight times more likely than females to suffer an ACL injury.

Accepted Answer

Women are actually 2 to 8 times more likely than men to suffer an ACL (anterior cruciate ligament) injury, largely due to differences in anatomy, muscle strength, and hormonal influences.

Question 8

The medial collateral ligament in the knee restrains valgus movements.

Accepted Answer

The medial collateral ligament (MCL) is located on the inner side (medial side) of the knee joint and helps to restrain valgus movements, which are movements that push the knee outward away from the midline of the body.

Question 9

Shin splints are also known as jumper's knee.

Accepted Answer

Shin splints are not the same as jumper's knee, which refers to pain in the patellar tendon. Shin splints, on the other hand, are pain and inflammation of the muscles and tendons along the shin bone.

Question 10

The gastrocnemius has been implicated as a cause of shin splints.

Accepted Answer

Shin splints are typically associated with pain along the inner edge of the shinbone, which is more closely related to the tibialis anterior and other muscles and tendons in the front and inner side of the shin, not the gastrocnemius, which is located in the calf area at the back of the leg.

Question 11

Of the following, which is not a joint associated with the shoulder?

Accepted Answer

The radial/ulnar joint is not a joint associated with the shoulder. It is a joint in the forearm that allows for the pronation and supination of the hand. The other options are all joints associated with the shoulder: the scapulothoracic joint is the connection between the shoulder blade and the thorax, the glenohumeral joint is the main joint of the shoulder connecting the upper arm bone to the shoulder blade, and the sternoclavicular joint is the connection between the collarbone and the sternum in the chest.

Question 12

Which of the following is a potential cause of the inflammation that causes a rotator cuff injury?

Accepted Answer

The answer of Which of the following is a potential...

Question 13

A stress fracture to one of the vertebrae is referred to as?

Accepted Answer

A stress fracture to one of the vertebrae is called spondylolysis. Impingement refers to pressure or compression on a specific body part or structure, a herniated disc is a condition where the cushion-like discs between the vertebrae in the spine slip out of place, and a sprain is an injury to a ligament.

Question 14

A bulging disc is when:

Accepted Answer

A bulging disc occurs when the nucleus pulposus (the soft gel-like substance in the center of the intervertebral disc) begins to push outwards towards the outer layers of the disc (the annulus fibrosus). This can cause compression or irritation of nearby nerves and lead to pain and other symptoms.

Question 15

During the sprinting motion, many hamstring injuries are caused by:

Accepted Answer

The eccentric contraction involved in uncoupling the heel from the hip puts a lot of stress on the hamstring muscles, making them more prone to injury. Bringing the heel to the hip (A) and lifting the foot off the ground (C) are part of the normal sprinting motion and do not necessarily cause hamstring injuries.

Question 16

Which knee ligament resists the forward motion of the tibia in relation to the femur?

Accepted Answer

The anterior cruciate ligament (ACL) is the knee ligament that resists the forward motion of the tibia in relation to the femur. It helps to keep the knee stable and prevent excessive movements that could cause injury or instability.

Question 17

Which structure prevents bone-on-bone contact between the femur and tibia?

Accepted Answer

The meniscus is a cushion-like structure made of cartilage that sits between the femur and tibia, preventing bone-on-bone contact and distributing weight evenly across the joint. The anterior cruciate ligament helps to stabilize the knee joint, but it does not prevent bone-on-bone contact. Tendons attach muscle to bone, and the periosteum is a thin layer of tissue that covers the surface of bones, but neither structure prevents bone-on-bone contact in the knee joint.

Question 18

Which is not thought t be a cause of shin splints?

Accepted Answer

Gender is not thought to be a cause of shin splints. Footwear, running surfaces, and training volume are all known factors that can contribute to the development of shin splints.

Question 19

Most ankle sprains are the result of what kind of injury?

Accepted Answer

Most ankle sprains are the result of an inversion injury, where the ankle rolls inward, causing the ligaments on the outside of the ankle to stretch or tear.

Question 20

Which of the following is not a hip adductor muscle?

Accepted Answer

The biceps femoris is actually a hip extensor and knee flexor muscle, not a hip adductor muscle. The other three muscles listed are all hip adductors.
