A 17-year-old boy with a stab wound received multiple injuries on the upper pa of the arm and required surgery. If the brachial aery were ligated at its origin, which of the following aeries would supply blood to the profunda brachii aery?
High-Yield Explanation
The posterior humeral circumflex aery anastomoses with an ascending branch of the profunda brachii aery, whereas the lateral thoracic and subscapular aeries do not. The superior ulnar collateral and radial recurrent aeries arise inferior to the origin of the profunda brachii aery.
