KNH 244 Final Exam questions with
verified answers
Elbow joint consists of - correct answer ✔✔3 joints, 1 capsule
Joints in the elbow - correct answer ✔✔Humeroulnar joint
Humeroradial joint
Proximal radio ulnar
Humeroulnar joint characteristics - correct answer ✔✔hinge joint between trochlea and trochlear notch
primary movement is flexion/extension
accessory movement: can move side to side slightly
Humeroradial joint characteristics - correct answer ✔✔between radial head (fovea) and humerus
resists valgus forces
roll and slide joint
valgus - correct answer ✔✔The distal end of the joint goes laterally
varus - correct answer ✔✔distal end of the joint goes medially
Proximal Radioulnar Joint - correct answer ✔✔radius, ulna bound by interosseous membrane
rotation of radius about ulna = pronate/ supinate
annular ligament attaches to ulnar on either side of radial notch
Intermediate Radioulnar joint - correct answer ✔✔no restriction of pronation/ supination
provides attachment for muscles
, helps transmit forces from radius to ulna
Distal Radioulnar Joint - correct answer ✔✔stabilized and allows distal end of radius to move
anteromedially over ulna
Elbow ligaments - correct answer ✔✔Capsule is strengthened by strong collateral ligaments on each side
Radial collateral lig
Annular lig of radius
Ulnar collateral lig
Radial collateral lig - correct answer ✔✔varus forces will cause injury
Annular lig of radius - correct answer ✔✔encircles and holds head of humerus in radial notch of ulna,
permits pronation/supination
Ulnar collateral lig - correct answer ✔✔from medial epicondyle to coronoid process of ulna (3 bands -
anterior, posterior, oblique)
valgus forces will cause injury
Pronation and Supination at elbow - correct answer ✔✔radial head spins on capitulum and articular
surface on side of head slides against radial notch of ulna
Pronation and Supination at distal radioulnar joint - correct answer ✔✔ulnar notch of radius slides
anteriorly over convex surface of head of ulna
3 parts of the hand - correct answer ✔✔Wrist, metacarpus, digits
Anterior surface of the hand is the - correct answer ✔✔palmar
Dorsal surface of the hand is the - correct answer ✔✔dorsal
