Upper Appendicular Skeleton
Cards in this deck (59)
- 1Sternoclavicular JointSaddle; formed from the sternal end of clavicle; can't rotate but can go forward/back and up/down; joint between axial skeleton and upper limb
- 2Acromioclavicular JointFixed; formed at acromial end of clavicle
- 3ScapulaFlat and triangular; glides over posterior surface of thorax
- 4Coracoid ProcessAttachment for the biceps brachii and other muscles of the shoulder
- 5AcromionJoins the scapula to the clavicle at the acromioclavicular joint
- 6Spine of the ScapulaForms a ridge that separates the posterior surface of the scapula into the supraspinous and infraspinous fossa; follows the acromion medially
- 7Supraspinous FossaCover posterior surface of the scapula; formed from spine of the scapula; house the rotator cuff muscles
- 8Infraspinous FossaCover posterior surface of the scapula; formed from spine of the scapula; house the rotator cuff muscles
- 9Subscapular FossaCover entire concave anterior surface of the scapula; faces the anterior surface of the ribs; house rotator cuff muscles
- 10Scapula (Rotator Cuff) MusclesHoused by 3 fossa of the scapula; rotate the humerus, stabilize the head of the humerus in the glenoid cavity
- 11Glenoid CavityShallow; where the rotator cuff muscles stabilize the head of the humerus
- 12Scapula Muscle ContractionMovement of the scapula on the thoracic wall; stabilize the position of the scapula
- 13Scapula ProtractionLateral and anterior movement; reach for something out of your reach
- 14Scapula RetractionMedial movement; occurs when scapula is pulled to the center of the back
- 15Scapula ElevationSuperior movement of scapula; shrugging shoulders
- 16Scapula DepressionInferior movement of scapula
- 17Head (Humerus)Near the two tubercles
- 18Greater Tubercle (Humerus)Lateral
- 19Lesser Tubercle (Humerus)Medial
- 20Intertubercular GrooveLies between the tubercles; attachment site for some muscles that move the humerus
- 21Anatomical NeckLocated at the epiphyseal plate; separates the head of the humerus from the diaphysis
- 22Surgical NeckNarrower region; more commonly fractured
- 23Glenohumeral JointBall and Socket; shoulder joint; wide range of motion due to shallow glenoid cavity
- 24Glenohumeral Internal RotationRotates the humerus inwardly
- 25Glenohumeral External RotationRotates the humerus outwardly
- 26Shoulder ExtensionMoves humerus posteriorly
- 27Shoulder FlexionMoves humerus anteriorly
- 28Shoulder AdductionMoves humerus toward the body
- 29Shoulder AbductionMoves humerus away from the body
- 30TrochleaProminent articular surface; spool-shaped; articulates with the ulna
- 31CapitulumProminent articular surface; spherical; articulates with the radius; good landmark
- 32Olecranon FossaPosterior surface of humerus; allows for full extension of elbow joint
- 33Medial EpicondyleProminent ridge outside the condyle; attachment for most anterior forearm muscles
- 34Lateral EpicondyleProminent ridge outside the condyle; attachment for some posterior forearm muscles
- 35Interosseous MembraneLigamentious connection that holds the bone together; along shaft of radius and ulna and terminates in a styloid process
- 36Styloid ProcessTermination of the interosseous membrane of the radius and ulna
- 37Humeroulnar JointHinge; elbow joint; between the humerus and ulna; limited to extension and flexion
- 38Humeroulnar ExtensionBends the elbow
- 39Humeroulnar FlexionStraightens the elbow
- 40Coronoid ProcessSide of the ulna that grips the trochlea of the humerus; smaller and more inferior than the olecranon process
- 41Olecranon ProcessSide of the ulna that grips the trochlea of the humerus; attachment site for extensors of the elbow; looks like a little divit/hook and its on the end
- 42Olecranon FossaLocated on the posterior humerus; permits full extension of the humeroulnar joint
- 43Humeroradial JointLooks like ball and socket; radius articulates with the capitulum; limited movement due to interosseous membrane and radioulnar joints; flexion, extension, and rotation of the radius
- 44Head (Radius)Rotates to produce supination
- 45Radius SupinationExternal rotation of the head of the radius against the capitulum; anterior facing palm (holding a bowl of soup); resting state
- 46Radius PronationDistal end of radius flips and crosses the ulna; moves the palm to face posteriorly (pouring the soup); crosses over- doing work
- 47Radioulnar JointPivot; primary joint of the wrist; lies near the humerus, radius, and ulna; allows for rotation of the wrist; flexion, extension, adduction, and abduction; any rotation of the wrist is pronation and supination
- 48Proximal CarpalsScaphoid, lunate, triquetrum, pisiform
- 49Distal CarpalsTrapezium, trapezoid, capitate, hamate
- 50Radial NotchPivot; crescent-shaped depression in the ulna where the radial head fits; permits rotation of the humeroradial joint for supination and pronation
- 51Radiocarpal JointCondyloid; can do flexion, extension, abduction, adduction; solely movement of the wrist
- 52Carpal JointsPlane;
- 53MetacarpalsI-V; make up the bones of the palm; articulate with 5 proximal phalanges and distal row of 4 carpals; carpometacarpal joints have minimal movements
- 54Metapophalangeal JointsCondyloid; found between metacarpal bones and proximal phalanges; flexion, extension, abduction, and adduction
- 55Proximal Interphalangeal JointsHinge; found between proximal and intermediate phalanx; flexion and extension
- 56Distal Interphalangeal JointsFound between intermediate and distal phalanges; flex and extend; pollex has no intermediate phalanx
- 57Proximal Phalanges3; make up digits II-V
- 58Intermediate Phalanges3; make up digits II-V
- 59Distal Phalanges3; make up digits II-V
