Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following bones would be the insertion point for the biceps?
A
Scapula
B
Humerus
C
Radius
D
Ulna
Explanation: 

Detailed explanation-1: -The biceps muscle inserts on the radial tuberosity of the upper extremity of the bone. The upper third of the body of the bone attaches to the supinator, the flexor digitorum superficialis, and the flexor pollicis longus muscles.

Detailed explanation-2: -The biceps brachii muscle is one of the chief muscles of the arm. The origin at the scapula and the insertion into the radius of the biceps brachii means it can act on both the shoulder joint and the elbow joint, which is why this muscle participates in a few movements of the arm.

Detailed explanation-3: -The tendon that attaches the biceps muscle to the forearm bones (radius and ulna) is called the distal biceps tendon.

Detailed explanation-4: -Proximally, the tendon of the short head of the biceps inserts onto the coracoid process and that of the long head on the superior aspect of the glenoid. The distal biceps tendon is bifurcated, and it generally inserts on the radial tuberosity, around which it rolls during pronation/supination.

Detailed explanation-5: -Biceps brachii – inserts on the radial tuberosity, a bony prominence on the medial aspect of the proximal end of the radius; allows for flexion and supination of the forearm.
