OT Anatomy & Physiology 5

Question 1

Which anatomical landmark is used to locate the median nerve at the wrist for carpal tunnel assessment?

Accepted Answer

Palmaris longus tendon

Answer

The median nerve lies just radial (lateral) to the palmaris longus tendon at the wrist; this tendon serves as a reliable surface landmark for nerve localization.

Question 2

During normal gait, which phase accounts for approximately 60% of the gait cycle?

Accepted Answer

Stance phase

Answer

Stance phase (foot contact with ground) comprises approximately 60% of the gait cycle, while swing phase accounts for the remaining 40%.

Question 3

Which part of the nephron is primarily responsible for reabsorption of glucose and amino acids?

Accepted Answer

Proximal convoluted tubule

Answer

The proximal convoluted tubule reabsorbs approximately 65% of filtered sodium, water, glucose, and amino acids via active transport mechanisms.

Question 4

A client with lateral epicondylitis has pain with which motion that stretches the common extensor origin?

Accepted Answer

Wrist flexion with elbow extension

Answer

Wrist flexion with elbow extension places maximal tension on the common extensor tendon origin at the lateral epicondyle, provoking pain in lateral epicondylitis.

Question 5

Which structure connects the two cerebral hemispheres and is critical for interhemispheric communication?

Accepted Answer

Corpus callosum

Answer

The corpus callosum is the largest white matter commissure, containing approximately 200–300 million axons that relay information between the left and right cerebral hemispheres.
