Arm anatomical model MP1515

for teaching

The long head of the biceps originates from the supraglenoid tubercle (not visible) and travels through the bicipital groove, while the short head arises from the coracoid process. The bifid insertion is clearly shown: the bicipital aponeurosis and the round tendon wrapping around the radius to insert on the radial tuberosity. Shoulder Region Structures Several preserved elements are visible around the shoulder joint, including partial stumps or tendons of the subclavius, subscapularis, pectoralis major, teres minor, infraspinatus, long head of triceps, and latissimus dorsi. The teres major tendon lies along the medial lip, and the pectoralis major tendon along the lateral lip of the bicipital groove. Also preserved are key shoulder ligaments: - Coracoclavicular ligament - Coracoacromial ligament - Coracohumeral ligament - Capsules of the shoulder and acromioclavicular joints The supraspinatus is the only complete rotator cuff muscle retained, and the suprascapular ligament is seen bridging the suprascapular notch. Elbow Joint Anatomy At the elbow, the joint capsule, annular ligament of the radius, and radial collateral ligaments are visible. The ulnar collateral ligament is not shown due to retention of both heads of flexor carpi ulnaris. This model is ideal for studying biceps anatomy, shoulder tendon insertions, and key ligamentous structures of the shoulder and elbow joints, making it a valuable tool for anatomical education and demonstration.
