Which muscles produce supination at the proximal radio-ulnar joint?
The supinator and biceps brachii produce supination, with assistance from the extensor pollicis longus (EPL) and extensor carpi radialis longus (ECRL).
Which muscles produce pronation at the proximal radio-ulnar joint?
The pronator quadratus primarily produces pronation, with assistance from the pronator teres.
What is the blood supply to the proximal radio-ulnar joint?
The radial portion of the peri-articular arterial anastomosis of the elbow joint supplies the proximal radio-ulnar joint.
Which nerves supply the proximal radio-ulnar joint?
The musculocutaneous, median, and radial nerves supply the proximal radio-ulnar joint.
What type of joint is the distal radio-ulnar joint?
The distal radio-ulnar joint is a pivot type of synovial joint.
