Chapter 4 Shoulder Girdle
Fichas del conjunto (26)
- 1Shoulder girdle actionsscapular elevation/depression, protraction/retraction, upward/ downward rotation
- 2What is the only attachment of upper extremity to the axial skeleton?Scapula and its attachment through clavicle at sternoclavicular joint
- 3Sternoclavicular ligament functionreinforces jt capsule limiting ant/post. motion of medial end of clavicle
- 4Costoclavicular ligament functionlimits amount of clavicular elevation
- 5Interclavicular ligament functionlimits amount of clavicular depression
- 6Acromioclavicular ligament functionprevents dislocation
- 7Coracolcavicular ligament function (know 2 parts of ligament)Conoid & Trapezoid. Together they prevent backward motion of scapula.
- 8Coracoacromial ligament functionprovides support to head of humerus when an upward force is transmitted along humerus. (FOOSH)
- 9Which ligament forms a roof over the head of the humerus?Coracoacromial Ligament
- 10What is Scapulohumeral Rhythm and what is the ratio?How the scapula moves in relationship with the humerus. 2:1 ratio of shoulder jt motion vs. shoulder girdle motion.
- 11Force couple for Upward Rotationupper traps pull up, lower traps pull down, serratus ant. pulls outwardly
- 12force couple for Downward Rotationpec. minor pulls down, rhomboid pulls in, levator scapula pulls up
- 13Scapular winging affects what muscle and what nerve?Serratus anterior, long thoracic nerve
- 14Motions of upper trapselevation, extension of the head
- 15motions of middle trapselevation, adduction, upper rotation
- 16motions of lower trapsadduction, depression, upward rotation
- 17Rhomboid actionsadduction, downward rotation, elevation
- 18Levator scapulae actionelevation
- 19Serratus Anterior actionsabduction, upward rotation
- 20Pectoralis Minor actionsabduction, downward rotation, depression
- 21Subclavius actiondepression
- 22Branches of C3&4 innervate what musclestraps, levator scapula
- 23Spinal Accessory nerve innervates what muscletraps
- 24Dorsal scapula nerve innervates what muscleslevator scapula, rhomboid
- 25long thoracic nerve C5,6&7 innervate what muscleserratus anterior
- 26Medial pectoral nerve C8 & T1 innervates what musclepectoralis minor
