  1. where is the flexor region anatomically?
    Anterior compartment of the forearm
  2. Where is the extensor region anatomically?
    The posterior compartment of the forearm
  3. What are the muscles of the anterior forearm
    • Pronator Teres
    • Flexor carpi radialis
    • Palmaris Longus 
    • Flexor Carpi ulnaris
  4. Pronator Teres
    • has 2 heads: long humeral and short ulnar
    • -attachments:Medial Supracondylar ridge of the humerus (common flexor tendon), coronoid process, and anterolateral radius
    • - Pronates arm at radioulnar joint
    • -median nerve
    • - ulnar artery, inferior ulnar collateral, anterior ulnar recurrent, and radial artery
  5. Flexor Carpi Ulnaris
    • -common flexor tendon, medial epidondyle , plamar aspect of 2nd and 3rd metacarpal
    • -Flexes and abduct at radiocarpal(wrist) joint
    • -median nerve
    • -radial artery and ulnar recurrent artery
  6. Palmar Longnus
    • -medial epi. common flex. tendon, palmar aponeurosis, and flexor retinaculum of hand
    • - flex hand at wrist and stablize hand aponeurosis
    • -median nerve
    • - median artery and anterior branch of ulnar recurrent artery
  7. Flexor Carpi Radialis
    • Medial epicondyle of the humerus via the common flexor tendon, palmar aspect of the base of the 2nd and 3rd metcarpal
    • - flexes the hand and the radiocarpal joint (wrist) abduct the hand at the radiocarpal and midcarpal joint
    • -median nerve
    • radial nerve and the posterior ulnar recurrent
  8. What is the special feature of the common flexor tendon
    It is the tendon for all 5 superficial muscles of the anterior arm
  9. What muscles attach to the medial epicondyle of the humerus?
    • flexor carpi radialis 
    • palmor longus
    • flexor carpi ulnaris
  10. Flexor digitorum superficialis
    • medial epicondyle of the humerus ( common flexor tendon), sublime tuberucle of the ulna,  and proxmial anteriro half of the border of the radius; palmar side of the middle phalanges 
    • - flexes index, middle, ring and pinky fingers
    • -median nerve
    • -anterior ulnar recurrent artery, ulnar and radial artery
  11. Flexor digiturum profundus
    • deep to the flexor d. superficialis
    • - insert on the coronoid process , anterior and medial surface of the ulnar; base of the distal all phalanges except the 1st digit (palmar side)
    • - median nerve and anterior interosseous part of the median nerve
    • -ulnar artery, inferior ulnar collateral, ulnar recurrent, and anterior interosseous arteries
  12. Pronator Quadratus
    • -distal 1/4 of ulnar and radius
    • -pronates forearm at radioulnar joints
    • -anterior antebrachial interosseous nerve
    • -anterior antebrachial interosseous artery
  13. Fexor Policis Longus
    • The THUMB!!!
    • -radius and interossesous memebrane of the forearm; base of distal pahalanx of digit 1
    • -flexes thumb
    • -anterior antebrachial interosseous nerve
    • -ant. antebrach. inteross. artery and radial artery
