UE, Bones, Joints, Ligaments Flashcards
T or F
Sternoclavicular joint is diarthrodial and classified as gliding
T
Only anatomical joint connection between axial and appendicular skeleton (typically fibrous)
T or F
Sternoclavicular ligament is covered by SCM and limits movement of clavicular head L to M
F
Sternoclavicular ligament is covered by SCM BUT limits movement of clavicular head A-P and P-A
Name the three ligaments of Sternoclavicular joint
Sternoclavicular ligament
Interclavicular ligament - between clavicular heads (limits inferior glide of clavicle)
Costoclavicular Ligament - limits elevation of clavicle
What are the acromioclavicular joint ligaments
Acromioclavicular ligament - Between acromion and clavicle
Coracoclavicular ligament - - Coniod portion: attaches at coniod tubercle of clavicle
- Trapezpoid portion ligament - attaches at trapezoid line of clavicle
Name and describe the ligaments of the scapula
Coracoacromial ligament - Connects coracoid process to acromion. Protects head of humerus. May impinge supraspinatus muscle or tendon
Transverse scapular ligament - Encloses suprascapular notch to form suprascapular foramen/canal. Suprascapular nerve transmitted through foramen/canal
T or F
The Gleniohumeral joint is a ball and socket joint, as well as diarthrodial
T
Allows for flexion, ext., abd., add., int. And ex. rot., circumduction
Name the three ligaments of the glenohumeral joint.
Superior, middle, inferior portions. Reinforce the articular capsule
T or F
The elbow joint is diarthrodial, and hinge.
T
This is distinct from the radioulnar joint
T or F
The radioulnar joint is a hinge joint.
F
Diarthrodial, pivot
Rotation (supination + pronation)
Name and describe the elbow ligaments
Annular ligament: encircles head of radius
Radial collateral ligament
Ulnar collateral ligament: often injured in throwing motions
T or F
The radio carpal joint (condyloid joint) is diarthrodial except rotation
T
Name and describe the radiocarpal joint ligaments
Scapholunate ligament: between scaphoid and lunate, most common writs sprain
Triangular fibrocartilage complex: between ulnar and carpals, creates smooth surface: often injured in falls
T or F
Intercarpal joints are diarthrodial, gliding and allow for flexion, extension, gliding
T
T or F
The carpometacarpal (1st) joint is diarthrodial. Saddle (sellar) = flexion, ext., add., abd., opp., reposition
T
The THUMB
T or F
Metacarpophalangeal joints are diarthrodial (condyloid)
T
All actions
The annular ligament of the radius does what?
Helps hold the head of the radius in place.
Clinical application can be called nursemaid’s elbow.
The upper etremity articulates with the axial skeleton at this joint and only at this joint.
Sternoclavicular
Ulnar collateral ligament
Originates from medial epicondyle of the humerus to the coronoid process and olecranon of the ulna. Can be damaged from repetitive throwing injuries.
Tommy John surgery to treat
Annular ligament
The annular ligament of the radius encircles the head of the radius, keeping it in contact with the radial notch of the ulna and allowing for supination and pronation.
*Kid throwing tantrum example = Injury to this is called nurse maids elbow.
