What are synovial joints?

Back

Synovial joints are the type of joints that allow the most movement in the body. They are characterized by a fluid-filled joint cavity, which provides lubrication and reduces friction between the articulating bones.

Front

What is the function of the MCL (Medial Collateral Ligament)?

Back

The MCL is a ligament located on the inner side of the knee that helps stabilize the joint by preventing excessive side-to-side movement.

Front

What is the Valgus Stress Test used for?

Back

The Valgus Stress Test is a special test used to assess the integrity of the MCL by applying a force to the outer side of the knee while the leg is slightly bent.

Front

What is shoulder flexion?

Back

Shoulder flexion is the movement of raising the arm forward and upward, decreasing the angle between the arm and the body.

Front

What is an example of a saddle joint?

Back

An example of a saddle joint is the joint at the base of the thumb, which allows for a wide range of motion including opposition.

Front

What are the characteristics of fibrous joints?

Back

Fibrous joints are connected by dense connective tissue and allow little to no movement. Examples include sutures in the skull.

Front

What is the role of the ACL (Anterior Cruciate Ligament)?

Back

The ACL is a key ligament in the knee that helps stabilize the joint by preventing the tibia from sliding too far forward relative to the femur.

Front

What is the purpose of the posterior drawer test?

Back

The posterior drawer test is used to assess the integrity of the PCL (Posterior Cruciate Ligament) by checking for excessive backward movement of the tibia.

Front

What is the range of motion in the elbow during flexion?

Back

During elbow flexion, the forearm moves closer to the upper arm, typically reducing the angle at the elbow joint.

Front

What are cartilaginous joints?

Back

Cartilaginous joints are joints where the bones are connected by cartilage, allowing for limited movement. An example is the joints between the vertebrae.
