Biceps brachii insertion on radius at tuberosity
Question asked:
“The biceps brachii inserts on the radius at the radial tuberosity.”
Summary
The biceps brachii tendon attaches to the radial tuberosity, a bony prominence on the proximal radius. This insertion site is consistently described in anatomical references.

The biceps brachii muscle (Fig. 12.14) has two origins; long head from supraglenoid tubercle of the scapula and short head from the coracoid process of the scapula. It inserts on the radial tuberosity and it is the primary supinator and important flexor of the forearm.
- Radial Tuberosity - an overview | ScienceDirect Topics
The radial (or bicipital) tuberosity is a blunt, rugose, variably shaped structure on the anteromedial side of the proximal radius. It marks the insertion of the biceps brachii muscle, a flexor and weak medial rotator of the forearm, and a large biceps bursa that underlies this muscle.

The standard deviations for the length and widths were small—2.3 mm and 2.8 mm, respectively—and attest to the relatively uniform morphology of the biceps tendon insertion. In 28 of 30 cases, the center of the biceps tendon inserted slightly anterior (mean, 2.9 mm) to the tuberosity apex (
- Distal biceps tendon insertion: an anatomic study - PubMed
To quantitatively describe the morphology of the distal biceps brachii insertion, 20 cadaveric arms were examined. Linear and angular measurements, including the footprint dimensions and shape, radial tuberosity dimensions and irregularities, and the rotational position of the tuberosity and footprint, were obtained.

Both tendons transition into their respective muscle bellies in the central third of the upper arm.[1][2] After crossing the cubital fossa, the biceps brachii continues as the bicipital aponeurosis, which inserts on the radial tuberosity and medial forearm fascia (see Image.

Origin: Short head: tip of coracoid process of scapula; Long head: supraglenoid tubercle of scapula Insertion: Tuberosity of radius and fascia of forearm via bicipital aponeurosis Action: Supinates forearm and, when it is supine, flexes forearm Innervation: Musculocutaneous nerve (C5 and C6 ...
