1. The coracobrachialis muscle shares a common origin with the short head of biceps brachii muscle.

Explanation

The coracobrachialis muscle and the short head of the biceps brachii muscle both originate from the coracoid process of the scapula. This means that they have a common starting point or origin. Therefore, the statement that the coracobrachialis muscle shares a common origin with the short head of the biceps brachii muscle is true.

2. Questions 22 through 25 refer to the figure below.

Which arrow points to the AC joint?

Explanation

The arrow that points to the AC joint is A.

Submit
3. Questions 50 through 53 refer to the figure below of an axial, T2-weighted MRI of the elbow.

Which arrow points to the annular ligament?

Explanation

The correct answer is C. In the given figure, the arrow labeled C is pointing to the annular ligament. This ligament is located around the head of the radius bone in the elbow joint. It helps to hold the radius bone in place and allows it to rotate during movements of the forearm.

Submit
4. Questions 50 through 53 refer to the figure below of an axial, T2-weighted MRI of the elbow.

Which arrow points to the pronator teres muscle?

Explanation

The arrow pointing to B indicates the pronator teres muscle. This muscle is located in the forearm and plays a role in pronating the forearm (rotating it so that the palm faces downward). It is situated near the elbow joint, which is why it can be seen in the axial MRI image of the elbow.

Submit
5. Which articulations of the elbow create the pivot joint that aids in supination and pronation of the elbow?

Explanation

The correct answer is Radiohumeral and radioulnar. The elbow joint consists of two articulations: the radiohumeral joint, which is formed between the radius and humerus, and the radioulnar joint, which is formed between the radius and ulna. These two articulations work together to allow for the movements of supination and pronation of the elbow.

Submit
6. Questions 46 through 49 refer to the figure below of an axial, T1-weighted MRI of the distal humerus.

Which arrow points to the brachioradialis muscle?

Explanation

8. The supraspinatus muscle:

Explanation

The supraspinatus muscle originates in the supraspinous fossa and inserts at the greater tubercle of the humerus. This means that it starts from a specific area in the scapula called the supraspinous fossa and attaches to a specific part of the humerus called the greater tubercle. This information helps us understand the location and function of the supraspinatus muscle in the shoulder joint.

Submit
9. What covers the articulating surfaces in synovial joints?

Explanation

Hyaline cartilage covers the articulating surfaces in synovial joints. This type of cartilage is smooth and provides a low-friction surface for the bones to move against each other. It also helps to absorb shock and distribute pressure evenly across the joint. The hyaline cartilage acts as a protective cushion, preventing the bones from rubbing against each other and reducing wear and tear on the joint.

Submit
10. Questions 46 through 49 refer to the figure below of an axial, T1-weighted MRI of the distal humerus.

Which arrow points to the triceps brachii muscle (lateral head)?

Explanation

not-available-via-ai

Submit
11. Questions 38 through 41 refer to the figure below of an axial, T1-weighted MRI of the right shoulder.

Which arrow points to the short head biceps brachii tendon?

Explanation

Submit
13. What ligament in the elbow attaches to the annular ligament?

Explanation

The correct answer is the radial collateral ligament. This ligament in the elbow attaches to the annular ligament. It helps to stabilize the joint and prevent excessive side-to-side movement.
