KROK 1 2011 – Question 47 · KROK (Medicine) · Human Anatomy
A 38-year-old patient came to a traumatology centre and complained about an injury of his right hand. Objectively: the patient has a cut wound in the region of the thenar eminence on the right hand; distal phalanx of the I finger cannot be flexed. What muscle was injured?
- A. Short abductor muscle of thumb
- B. Abductor muscle of thumb
- C. Opposer muscle of thumb
- D. Long flexor muscle of thumb
- E. Short flexor muscle of thumb
Hint
Ask which muscle's tendon inserts on the distal phalanx of the first finger, since a cut in the thenar region has removed flexion of exactly that segment.
