Where could one find the coronary ligament?

Knee

Heart

Lungs

Pericardium

Shoulder

Explanation

There are two different coronary ligaments in the body. The coronary ligament of the liver serves to connect the liver to the inferior surface of the diaphragm; as this is not an answer option, we must be looking at the second type of coronary ligament.

The coronary ligament of the knee serves to connect the menisci to the tibial condyles, and is continuous with the joint capsule of the knee.

Which are the only two saddle joints of the body?

Sternoclavicular and trapeziometacarpal

Acromioclavicular and interphalangeal

Carpometacarpal and sternoclavicular

Radioulnar and tibiofibular

None of these

Explanation

The sternoclavicular and trapeziometacarpal (thumb) joints are unique in that the involved bones have both convex and concave portions that give their saddle shape.

5

Which of the following two shoulder joints work together to combine movements to allow for an increase in "reach" of the upper limb?

Sternoclavicular and acromioclavicular

Sternoclavicular and glenohumeral

Glenohumeral and acromioclavicular

Acromioclavicular and sternohumeral

Sternohumeral and glenohumeral

Explanation

The sternoclavicular and acromioclavicular joints link two bones of the pectoral girdle to each other and to the trunk of the body. They also combine their movements to increase reach length of the upper limb. They are both synovial joints and surrounded by a joint capsule with numerous ligaments to reinforce their movements. The glenohumeral joint serves in articulation of the humerus and scapula. The Sternohumeral joint does not exist.

7

Name the suture that connects the parietal bones to the occipital bone.

Lambdoid suture

Sagittal suture

Coronal suture

Squamous suture

Metopic suture

Explanation

Fibrous joints are responsible for connecting the bones of the skull. The lambdoid suture is the fibrous joint found on the posterior portion of the skull, and is used to connect the occipital bone to the parietal bones.

The coronal suture connects the frontal bones and parietal bones. The sagittal suture joins the parietal bones to one another. The squamous suture joins the parietal and temporal bones. The metopic suture joins the two frontal bones to one another.

9

Which of the following ligaments is not a part of the deltoid ligament of the ankle?

Calcaneofibular

Tibionavicular

Tibiocalcaneal

Anterior tibiotalar

Posterior tibiotalar

Explanation

The calcaneofibular ligament is located on the lateral side of the ankle instead of the medial side where the deltoid ligament is located. All other ligaments are part of the deltoid ligament of the ankle.

10

Which is the weaker of the three ball-and-socket joints?

None of these

The elbow, shoulder, and ankle

The knee, hip, and the shoulder

The elbow, knee, and hip

The ankle, hip, and knee

Explanation

There are only two ball and socket joints in the human body. They are the hip and the shoulder joints (there are two in the hip and one in each shoulder). Of the two areas where there are ball and socket joints, the shoulder is the weakest. More shoulder dislocations occur than any other joint. The greater the range of movement, generally the weaker the joint is. Unlike the hip which has a deeper depression for the femur to fit into, the shoulder joint has a relatively shallow depression for the humerus to fit into. This coupled with its weaker tendons makes it the weaker of the two ball and socket joints.
