The Attachment Site for the Biceps Brachii Muscle to the Radius

Question

The attachment site for the biceps brachii muscle to the radius is at the
A) deltoid tuberosity.
B) greater tubercle.
C) radial tuberosity.
D) brachial tuberosity.
E) styloid process of the radius.

Accepted Answer

The radial tuberosity is the roughened, oblong eminence found along the medial, anterior aspect of the shaft of the radius bone, just below the neck. The biceps brachii muscle originates from the supraglenoid tubercle of the scapula, and the coracoid process of the scapula, and inserts onto the radial tuberosity.
