Damage here can affect the biceps tendon (loss of forearm supination and elbow flexion), the brachial artery (acute forearm ischaemia, reduced distal pulses), or the median nerve (loss of forearm pronation, thenar weakness, sensory loss in the lateral hand). The bicipital aponeurosis forms a protective layer over the artery and nerve, which is why venepuncture is usually safe when done correctly. Knowing what sits where turns anatomy from memorisation into clinical reasoning. #anatomy #medtok #m
