Presentation Transcript

  1. LAKAT I PODLAKTICA

  2. Zglobovi lakta • humeroulnarni zglob (trohlea humerusa i konkavna trohlearna incisura) • humeroradijalni zglob (glavica humerusa i glava radijusa) • proksimalni radioulnarni zglob (cirkumferencija glave radijusa i konkavna incisura ulne)

  3. Zglobovi lakta • srednji radioulnarni zglob koji čine radijus, ulna i međukoštana membrana • distalni radioulnarni zglob (konveksna glava ulne i konkavna ulnarna incisura radijusa)

  4. Pokreti lakta • fleksija i ekstenzija oko transverzalne osi • supinacija i pronacija oko longitudinalne osi

  5. Ligamenti lakta • lig collaterale ulnare( anterior, posterior ) • lig collaterale radiale • lig anulare radii

  6. Lig anulare radii Tet.m biceps brachii Lig colaterale uln, ant Lig colaterale uln post

  7. Lig colaterale radiale Lig colaterale ulnare

  8. Mišići lakta i podlaktice • FLEKSORI • M biceps brachii • M brachialis • M brachioradialis m pronator teres m extensor carpi radialis longus m extensor carpi radialis brevis

  9. M bic brachi cap longum M biceps brachi cap breve M brachialis M brachioradialis

  10. EXSTENZORI • m triceps brachii • m anconeus

  11. M triceps brachii m extensor carpi rad longus

  12. SUPINATORI • M biceps brachii • M supinator m abductor policis longus m extensor policis brevis m extensor indicis proprius

  13. PRONATORI • m pronator teres • m pronator quadratus m fleksor carpi radialis m palmaris longus m ekstenzor carpi radialis longus

  14. M supinator M supinator M pronator teres cap ulnare M pronator teres M pronator teres cap humerale M pronator quadratus

  15. Abdukcijski kut ili kut nošenja • longitudinalna osovina nadlaktice i podlaktice čine kut od 5-10 stup. (muški), tj. 10-15 stup.(žene) • mijenja se ovisno o kretnjama podlaktice
