Flashcards in Pre-practical Upper Limb Deck (42)
What is the cavity of the shoulder joint called?
What cartilage is found along the rim of the glenoid cavity?
What bone acts as a link between the apical and axial skeletons?
What is the weakest pat of the shoulder capsule?
Name the ligaments supporting the shoulder capsule.
Which bursa is continuous with the synovial cavity of the shoulder cavity?
Name the bursa of the shoulder joint.
Name the muscles of the rotator cuff.
What is the scapula-humeral rhythm?
The scapula and humerus move in 1:2 ratio. When the arm is abducted 180 degrees, 60 degrees occurs by rotation of the scapula and 120 degrees by rotation of the humerus at the shoulder joint
What can scapular injury affect?
Movement at the shoulder joint
What movements can occur at the shoulder joint?
-Flexion and extension
-Medial and lateral rotation
-Abduction and adduction
What are the movements of the scapula?
What muscles are involved in depression off the scapula?
What muscles are involved in elevation of the scapula?
What muscles are involved in retraction of the scapula?
What muscles are involved in protraction of the scapula?
What muscles are involved in external rotation of the scapula?
What muscles are involved in internal rotation of the scapula?
What are the borders of the axilla?
-Pectoralis major and minor
-Serratus anterior and thoracic wall
-Scapularis, teres major and latissimus dorsi
What muscles does the brachial plexus emerge between?
Anterior and posterior scalene muscles
What are the contents of the cubital fossa?
What are the borders of the cubital fossa?
-Imaginary line between epicondyles
-Medial border of brachioradialis
-Lateral border of pronator teres
Name the parts of the superior ulna.
Name the parts of the superior radius.
What ligament holds the radius against the ulna?
What are the superficial veins of the upper limb?
-Dorsal venous arch
What does the dorsal venous arch drain into?
-Basilic vein (medial side)
-Cephalic vein (lateral side)
What is the course of the cephalic vein?
Pierces the clavipectoral fascia at the upper end of the deltopectoral groove to enter the axillary vein
What is the course of the basilica vein?
Pierces the fascia in the medial mid arm to join the venae commitants which together, at the inferior border of teres major becomes the axillary vein
