  1. What are the compartments of the forearm?
    • There are two compartments:
    • - anterior;
    • - posterior.
  2. There are two layer of muscles in the anterior compartment of the forearm. True or Fals?
    • False. There are three layers in the anterior compartment:
    • - superficial;
    • - medial;
    • - deep.
  3. How the forearm is innervated?
    The forearm is supplied by Median and Ulnar nn in the anterior compartment and Radial n in the posterior compartment.
  4. Palmaris Longus m is absent in up to 25% people. True or False.
    False. The PL m is absent in 14% of people, most commonly on the left side.
  5. All muscles supplying the Anterior Compartment of the forearm are proximally attached to Radius, Ulna and Antebrachial Fascia. True or False?
    False. The muscles of the superficial and intermediate layer are attached both to the humerus and the forearm.
  6. What muscles for the Superficial Layer of the Aterior Compartment of the forearm?
    • There are four muscles from medial to lateral:
    • - Pronator Teres m (C6-7 Mn);
    • - Flexor Carpi Radialis m (C6-7 Mn);
    • - Palmaris Longus m (C7-8 Mn);
    • - Flexor Carpi Ulnaris m (C7-8Un).
  7. What muscles form the deep layer of the Anterior Compartment of the Forearm?
    • There are three muscles forming the deep layer of the Anterior Compartment of the Forearm:
    • - Flexor Digitorum Superficialis m;
    • - Flexor Pollicis Longus m:
    • - Pronator Quadratus m;
  8. The Flexor Digitorum Profundus m lies deep to the Pronator Quadratus m.. True or False?
    False. The Peronator Quadratum if the deepest muscle of the forearm.
  9. The distal attachment of the Flexor Carpi Ulnaris is to the base of the 5th metacarpal bone. True or False?
    False. The Flexor Carpi Ulnaris is distally attached to the Pisiform and the Hook of Hamate bones.
  10. The distal attachment of the Palmaris Longus m is to the proximal part of the Flexor Retinaculum. True or False?
    False. The PL m is distally attached to the distal end of the Flexor Retinaculum and apex of Palmar Aponeurosis.
  11. The neurovascular bundle of the anterior cmpartment of the forearm lies between the Intermediate and the Deep muscle layers of the compartment. True or False?
    True.
  12. The Radial artery and nerve lie medial to the tendon of the flexor Carpi Radialis m. True or False?
    False. The Radial a et n lie lateral to the tendon of the Flexor Carpi Rdialis m, between FCR m medially and PT m laterally with the Radial n lying lateral to the Radial a.
  13. The Ulnar n et a lie lateral to the tendon of flexor Carpi Ulnaris. True or False?
    True. The artery and the nerve lie lateral to the tendon FCU m with nerve being medial to the artery, between the FCU tendon and the Ulnar a.
  14. How to memorize positions of the Radial and Ulnar arteries and nerves in the wrist?
    • Radial nerve lies more radial to the Radial artery.
    • Ulnar nerve lies more ulnar to the Ulnar artery.
  15. Nae muscles in the forearm that take their origin in the Common Flexor Origin.
    • - Poronator Teres m;
    • - Flexor Carpi Radialis m;
    • - Palmaris Longus m;
    • - Flexor Carpi Ulnaris m;
    • - Flexor Digitorum Superficialis m
  16. Name musccles of the Anterior Compartment of the forearm that have two proximal attachments.
    • - Ptonator Teres m;
    • - Flexor Carpi Ulnaris m;
    • - Flexor Digitorum Superficialis m;
    • - Flexor Digitorum Profundus m.
  17. Which muscles are attached to the common Extensor Origin?
    • - ECRB;
    • - ED;
    • - EDM.
  18. What is the nerve supply for the Extensor Digiti Minimi m?
    Radial n (C7,8).
  19. What is the nerve supply for the Extensor Cari Radialis Brevis m?
    The ECRB is supplied by the Radial n (C7,8).
  20. What is the nerve supply for the Extensor Digitorum m?
    The Extensor Digitorum m is supplied by the Radial n (c7,8).
  21. The Brachioradialis m is supplied by which nerve?
    The Brachioradialis m supplied by the radial n (C5,6,7).
  22. Which muscle of the posterior forearm has two proximal attachmets?
    The Extensor Carpi Ulnaris m. The muscle is attached to the Lateral Condyle of the Humerus and the Poserior Border of Ulna via Shared Aponeurosis.
