Week 4-Functional anatomy upper limb SUP Flashcards
The shoulder girdle consists of four joints?
Sternoclavicular
Acromioclavicular
Glenohumeral (shoulder joint)
Scapulothoracic
Sternoclavicular joint?
Strongly reinforced by musculature, due to >ROM
Strongest joint capsule to prevent subluxation / dislocation (bone on bone)
Acromioclavicular Joint?
Joint handles large contact stresses (hip and shoulder bump) due to large axial loading
GLENOHUMERAL (Shoulder) JOINT?
Large ROM due to size differences between humeral head and glenoid fossa
Muscles of the Shoulder Girdle?
All originate on axial skeleton
Provide dynamic stability of the scapula
Glenohumeral Musculature?
Proximal Humeral Attachments
Distal Humeral Attachments
Dislocation of the Shoulder?
Scapula processes prevent superior
Inferior rare due to musculature
Shoulder Injuries?
Limited DOF for energy dissipation – easier to break
Elbow Joint Structure 3 joints?
Humeroulnar
Humeroradial
Proximal Radioulnar
Structure of the Carpometacarpal and Intermetacarpal Joints?
Thumb ROM enhanced due to ROM of Trapezium
Movements descriptors from anatomical position
Carpal Tunnel Syndrome?
Inflammation and or compression of the structures of the wrist that pass through the carpal tunnel
