Which of the following is also an insertion site for the biceps brachii, besides the radius tuberosity?

• A. Intertubercular Groove of Humerus
• B. Aponeurosis of the Biceps Brachii
• C. Glenoid Cavity
• D. Coracoid Process

Answer: (B)

The muscle can insert not only at the radial tuberosity but also through a broad sheet called the bicipital aponeurosis (lacertus fibrosus) that blends with the forearm fascia. This aponeurosis distributes the pull of the biceps over the forearm and helps anchor the muscle belly to the antebrachial fascia, providing additional attachment beyond the radius.

The other options are not insertions. The intertubercular groove is a path the tendon follows, not an insertion point. The glenoid cavity and the coracoid process are sites of origin for the long and short heads, respectively, not distal insertions.
