- Radial head of flexor digitorum superficialisCaput radiale flexoris superficialis digitorumThe radial head is the thin lower origin of flexor digitorum superficialis, arising from the front of the radius below the elbow.
- Scapular spinal part of deltoid musclePars spinalis scapularis musculi deltoideiThe spinal part of the deltoid is its posterior portion, arising from the scapular spine and drawing the arm backward.
- Short head of biceps brachiiCaput breve musculi bicipitis brachiiThe short head of biceps brachii starts on the coracoid process and forms the medial belly of the biceps on the front of the arm.
- Subscapularis muscleMusculus subscapularisSubscapularis is the large rotator cuff muscle on the front of the shoulder blade that turns the arm inward.
- Superficial head of flexor pollicis brevisCaput superficiale flexoris brevis pollicisThis superficial head is the main thenar part of the short thumb flexor, bending the thumb at its knuckle.
- Superficial head of pronator teresCaput superficiale pronatoris teretisThe superficial head of pronator teres is its larger, humeral head, arising just above the inner elbow and turning the palm down.
- Superficial transverse metacarpal ligamentLigamentum metacarpeum transversum superficialeThe superficial transverse metacarpal ligament is a band of crosswise fibres in the distal palm, part of the palmar aponeurosis near the finger bases.
- SupinatorThe supinator is a short, broad muscle wrapped around the upper radius in the deep layer of the back of the forearm.
