OT Anatomy & Physiology 3

Question 1

Which type of joint allows the greatest range of motion and is classified as a multiaxial synovial joint?

Accepted Answer

Ball-and-socket joint

Answer

Ball-and-socket joints (e.g., hip, shoulder) allow movement in all three planes plus circumduction, making them the most mobile joint type.

Question 2

In a patient with C6 spinal cord injury, which muscle function is preserved that allows tenodesis grasp?

Accepted Answer

Wrist extensors (ECRL/ECRB)

Answer

C6 SCI preserves wrist extension, enabling passive finger flexion through tenodesis as the wrist extends, allowing a functional grasp without active finger flexors.

Question 3

The saphenous nerve, a branch of the femoral nerve, provides sensory innervation to which area?

Accepted Answer

Medial leg and foot

Answer

The saphenous nerve is the terminal sensory branch of the femoral nerve, supplying the medial aspect of the leg from the knee to the medial foot.

Question 4

Which lung lobe is most commonly affected by aspiration pneumonia in a supine patient?

Accepted Answer

Right lower lobe (posterior segment)

Answer

In supine patients, gravity directs aspirated material to the posterior segment of the right lower lobe due to the more vertical angle of the right main bronchus.

Question 5

Which anatomical structure separates the anterior and posterior compartments of the thigh?

Accepted Answer

Lateral and medial intermuscular septa

Answer

The lateral and medial femoral intermuscular septa extend from the fascia lata to the femur, separating the anterior, posterior, and medial thigh compartments.
