    Which of the following groups are the prime movers in elbow flexion?

    • Biceps, supinator, and brachialis

    • Brachialis, brachioradialis, and anconeus

    • Biceps, Pronator teres, and supinator

    • Brachialis, Biceps, and Brachioradialis

    Correct Answer
    A. Brachialis, Biceps, and Brachioradialis
    Explanation
    The prime movers in elbow flexion are the muscles responsible for initiating and carrying out the movement. In this case, the brachialis, biceps, and brachioradialis are the primary muscles involved in flexing the elbow joint. These muscles work together to contract and shorten, causing the forearm to move towards the upper arm. The biceps muscle is the most well-known and prominent muscle in this group, but the brachialis and brachioradialis also play important roles in elbow flexion.

    The bony end landmark of the ulna, which forms the prominent posterior point of the elbow is which of the following?

    • Olecranon fossa

    • Olocranon Process

    • Coroniod process

    • Radial head

    Correct Answer
    A. Olocranon Process
    Explanation
    The bony end landmark of the ulna that forms the prominent posterior point of the elbow is the olecranon process. This bony projection can be easily palpated and is important for the attachment of muscles and ligaments involved in elbow movement. The olecranon process acts as a lever during extension of the forearm and provides stability to the elbow joint. The other options mentioned, such as the olecranon fossa, coronoid process, and radial head, are not the correct answer as they are different anatomical structures within the elbow joint.

    The weakness of the biceps brachii muscle could indicate Trauma to which of the following nerves?

    • Musculocutaneous Nerve

    • Median nerve

    • Ulnar nerve

    • Radial Nerve

    Correct Answer
    A. Musculocutaneous Nerve
    Explanation
    The weakness of the biceps brachii muscle suggests trauma to the musculocutaneous nerve. The musculocutaneous nerve innervates the biceps brachii muscle, which is responsible for flexing the elbow joint. If there is weakness in this muscle, it indicates damage or trauma to the musculocutaneous nerve, which supplies the motor function to the biceps brachii muscle.

    The Muscle that would act on the forearm to neutralize forearm supination would be which of the following muscles?

    • Triceps and pronator teres

    • Pronator teres and Pronator Quadratus

    • Brachialis and Brachioradialis

    • Triceps and Anconeus

    Correct Answer
    A. Pronator teres and Pronator Quadratus
    Explanation
    The muscles that would act on the forearm to neutralize forearm supination are the pronator teres and pronator quadratus. These muscles work together to rotate the forearm inward, counteracting the outward rotation of supination. The triceps and anconeus muscles are responsible for extending the forearm, while the brachialis and brachioradialis muscles are involved in flexion of the forearm. Therefore, the correct answer is pronator teres and pronator quadratus.

    Which muscle originates on the humeral lateral condyle and inserts on the radial styloid process?

    • Brachioradialis

    • Flexor carpi radialis

    • Pronator teres

    • Pronator quadratus

    Correct Answer
    A. Brachioradialis
    Explanation
    The muscle that originates on the humeral lateral condyle and inserts on the radial styloid process is the brachioradialis. This muscle is located in the forearm and is responsible for flexing the forearm at the elbow joint. It is innervated by the radial nerve and plays a role in stabilizing the wrist during certain movements.

    The bony landmark located at the posterior lateral side of the radius at the distal end is called the?

    • Olocranon process

    • Radial tuberosity

    • Radial head

    • Styloid process

    Correct Answer
    A. Styloid process
    Explanation
    The bony landmark located at the posterior lateral side of the radius at the distal end is called the styloid process.

    Rate this question:

  • 8. 

    Elbow extension occurs in which plane and through which Axis?

    • Transverse plane through a vertical axis

    • Frontal plane through a sagittal axis

    • Sagittal plane through a frontal axis

    • Transverse plane through a transverse axis

    Correct Answer
    A. Sagittal plane through a frontal axis
    Explanation
    Elbow extension occurs in the sagittal plane through a frontal axis. The sagittal plane divides the body into left and right halves, while the frontal axis runs from side to side. Elbow extension refers to straightening or extending the elbow joint, which involves the movement of the forearm away from the upper arm in the sagittal plane around the frontal axis.

    When you have a patient do a chair push up to strengthen the elbow triceps, what type of kinetic chain activity is this?

    • Open chain

    • Closed Chain

    • This exercise has elements of both closed and open chains

    • Neither

    Correct Answer
    A. Closed Chain
    Explanation
    When a patient performs a chair push up to strengthen the elbow triceps, it is considered a closed chain activity. In a closed chain activity, the distal segment of the body (in this case, the hands) is fixed or in contact with a stable surface (the chair), while the proximal segment (the upper body) moves. In this exercise, the hands are fixed on the chair while the upper body moves up and down, making it a closed chain activity.

    The broad, flat membrane located at the posterior lateral side of the radius at the distal end is called the?

    • Thoracolumbar fascia

    • Joint capsule

    • Interosseous membrane

    • Annular ligament

    Correct Answer
    A. Interosseous membrane
    Explanation
    The interosseous membrane is a broad, flat membrane located at the posterior lateral side of the radius at its distal end. It serves as a connection between the radius and ulna bones in the forearm, providing stability and support to the joint. The interosseous membrane helps to distribute forces between the two bones during movement and also allows for slight rotation of the radius around the ulna.

  • 11. 

    Your patient has point tenderness at the common flexor origin at the elbow. Given this symptom, which diagnosis is likely?

    • Medial epicondylitis

    • Lateral epicondylitis

    • Tendonitis of biceps tendon

    • Volkmann's ischemic contracture

    Correct Answer
    A. Medial epicondylitis
    Explanation
    Point tenderness at the common flexor origin at the elbow is a characteristic symptom of medial epicondylitis, also known as golfer's elbow. This condition is caused by inflammation or irritation of the tendons that attach to the medial epicondyle, resulting in pain and tenderness on the inner side of the elbow. Lateral epicondylitis, also known as tennis elbow, would cause pain on the outer side of the elbow. Tendonitis of the biceps tendon would cause pain in the front of the elbow, and Volkmann's ischemic contracture is a condition characterized by muscle and nerve damage due to decreased blood flow, which would not typically present with point tenderness at the common flexor origin.

    Which ligament spans the elbow longitudinally (long ways) on the little finger side of the elbow?

    • Lateral collateral ligament

    • Annular ligament

    • Medial collateral ligament

    • Proximal radioulnar ligament

    Correct Answer
    A. Medial collateral ligament
    Explanation
    The medial collateral ligament spans the elbow longitudinally on the little finger side of the elbow. It is responsible for providing stability to the inner side of the elbow joint and preventing excessive side-to-side movement.

    Rate this question:

  • 15. 

    The weakness of the pronator teres muscle could indicate trauma to which of the following nerves?

    • Musculocutaneous nerve

    • Median Nerve

    • Ulnar nerve

    • Radial Nerve

    Correct Answer
    A. Median Nerve
    Explanation
    The weakness of the pronator teres muscle could indicate trauma to the Median Nerve. The pronator teres muscle is innervated by the Median Nerve, which means that damage or trauma to this nerve can result in weakness or paralysis of the muscle. The other nerves listed (Musculocutaneous, Ulnar, and Radial) do not innervate the pronator teres muscle, so damage to these nerves would not cause weakness in this specific muscle.

    Rate this question:

  • 16. 

    The carrying angle at the elbow exists because of which of the following phenomena at the distal end of the humerus?

    • The lateral structures extend farther distally the the medial structures

    • The medial stuctures extend farther distally the the lateral structures

    • The anterior structures extend farther distally than the posterior structures

    • The posterior structures extend farther than the anterior structures

    Correct Answer
    A. The medial stuctures extend farther distally the the lateral structures
    Explanation
    The carrying angle at the elbow exists because the medial structures extend farther distally than the lateral structures. This anatomical difference causes the forearm to naturally angle away from the body when the arm is fully extended.

  • 17. 

    A common elbow pathology often caused by repetitive wrist extension activities is which of the following?

    • Medial epicondylitis

    • Lateral epicondylitis

    • Tendonitis of biceps tendon

    • Volkmann's ischemic contracture

    Correct Answer
    A. Lateral epicondylitis
    Explanation
    Lateral epicondylitis, also known as tennis elbow, is a common elbow pathology caused by repetitive wrist extension activities. It is characterized by inflammation and pain on the outer side of the elbow. This condition is commonly seen in individuals who engage in activities such as tennis, painting, or typing, which involve repetitive use of the wrist and forearm muscles. Medial epicondylitis, on the other hand, refers to inflammation and pain on the inner side of the elbow, and is caused by repetitive wrist flexion activities. Tendonitis of the biceps tendon and Volkmann's ischemic contracture are unrelated conditions.

  • 18. 

    Measured from the position of the forearm in neutral or mid-position, which of the following is true regarding normal ROM  for pronation and supination?

    • There is more supination than pronation

    • There is more pronation than supination

    • There are equal amounts of available pronation and supination

    • It depends on how much elbow extension the arm is placed in to measure the motion.

    Correct Answer
    A. There is more supination than pronation
    Explanation
    The correct answer is "There is more supination than pronation." This means that the forearm has a greater range of motion in the supination direction compared to pronation.

    Which muscle originates on the humeral medial epicondyle and proximal ulna and spans the elbow anteriorly to attach on the lateral surface of the radius near its midpoint?

    • Supinator

    • Anconeus

    • Pronator teres

    • Brachialis

    Correct Answer
    A. Pronator teres
    Explanation
    The pronator teres muscle originates from the humeral medial epicondyle and proximal ulna. It spans the anterior aspect of the elbow and attaches to the lateral surface of the radius near its midpoint. This muscle facilitates forearm pronation, enabling movements like turning a screwdriver or opening a jar.

    The elbow flexor that is most effective (strongest) with the forearm in the neutral position is which of the following muscles?

    • Biceps brachii

    • Brachioradialis

    • Brachialis

    • Coracobrachialis

    Correct Answer
    A. Brachialis
    Explanation
    The brachialis muscle is the most effective (strongest) elbow flexor with the forearm in the neutral position. This is because the brachialis muscle is located deep to the biceps brachii and attaches to the ulna, which allows it to generate a greater force for flexion. The biceps brachii is also a strong elbow flexor, but it is more effective when the forearm is supinated (turned palm up). The brachioradialis and coracobrachialis muscles are also elbow flexors, but they are not as strong as the brachialis.

    Rate this question:

  • 21. 

    The position of the elbow and shoulder that could potentially make the biceps brachii muscle actively insufficient would be which of the following?

    • Shoulder extension and elbow flexion

    • Shoulder flexion and elbow flexion

    • Shoulder flexion and elbow flexion

    • Shoulder extension and elbow extension

    Correct Answer
    A. Shoulder flexion and elbow flexion
    Explanation
    When the shoulder is flexed and the elbow is flexed, the biceps brachii muscle is in a shortened position. This means that the muscle is already contracted, and further flexion at both joints would not allow the muscle to generate a strong contraction. This is known as active insufficiency, where the muscle is unable to produce an optimal force due to being in a shortened position at both joints. Therefore, shoulder flexion and elbow flexion would potentially make the biceps brachii muscle actively insufficient.

    Rate this question:

  • 22. 

    The weakness of the Triceps brachii muscle could indicate trauma to which of the following nerves?

    • Musculocutaneous nerve

    • Medial Nerve

    • Ulnar Nerve

    • Radial Nerve

    Correct Answer
    A. Radial Nerve
    Explanation
    Weakness in the Triceps brachii muscle may indicate trauma to the radial nerve. The radial nerve innervates the Triceps brachii, responsible for extending the elbow joint. Damage to this nerve can lead to weakness or paralysis of the Triceps brachii muscle, affecting elbow extension and overall arm function.
