CCEP Extremity Anatomy 5

Question 1

The quadrangular (quadrilateral) space transmits which neurovascular structures?

Accepted Answer

Axillary nerve and posterior circumflex humeral artery

Answer

The quadrangular space, bounded by teres minor, teres major, long head of triceps, and humerus, transmits the axillary nerve and posterior circumflex humeral artery.

Question 2

Which structure prevents anterior displacement of the femoral head on the tibia during knee flexion?

Accepted Answer

Anterior cruciate ligament

Answer

The anterior cruciate ligament (ACL) primarily resists anterior tibial translation relative to the femur and also limits internal rotation of the tibia.

Question 3

The flexor digitorum superficialis (FDS) inserts on which part of the digit?

Accepted Answer

Middle phalanx (palmar sides)

Answer

The FDS splits into two slips (Camper's chiasm) and inserts on the palmar sides of the middle phalanx of digits 2–5, flexing the PIP joint primarily.

Question 4

Which of the following best describes the path of the popliteal artery in the popliteal fossa?

Accepted Answer

Deepest structure, closest to the femur and tibia

Answer

In the popliteal fossa, the popliteal artery is the deepest structure, lying directly on the posterior capsule of the knee joint, with the vein and tibial nerve progressively more superficial.

Question 5

The spring (calcaneonavicular) ligament supports which structure from below?

Accepted Answer

Head of the talus

Answer

The plantar calcaneonavicular (spring) ligament spans from the sustentaculum tali to the navicular, providing critical inferior support for the talar head and maintaining the medial longitudinal arch.
