Insertion of the biceps brachii includes which of the following?

Explanation:
This question is about where the biceps brachii attaches distally. The biceps has a two-part distal insertion: the main tendon attaches to the tuberosity of the radius, providing the primary anchor for elbow flexion and forearm supination, and a bicipital aponeurosis (lacertus fibrosus) extends from the tendon and blends with the fascia of the forearm (antebrachial fascia). This aponeurosis helps distribute the muscle’s tension across the forearm, stabilizing the region during movement. The olecranon is the insertion for the triceps, not the biceps. So the biceps inserts both at the radius tuberosity and via its aponeurosis into the forearm fascia.
