|
Which structure contains the articular surface for the should joint?
|
Scapula - glenoid fossa and Humerus - head
|
|
|
Which structure of the scapula lies against the chest wall?
|
Subscapular fossa
|
|
|
Which structure of the humerus articulates with the radius?
|
capitulum
|
|
|
What structure of the humerus articulates with the ulna?
|
trochlea
|
|
|
Which parts of the ulna are readily palpable subcutaneously?
|
Olecranon at the posterior of the elbow joint, styloid process at the medial side of the wrist
|
|
|
Which parts of the radius help form the radio-ulnar joints?
|
Proximal: Head of the Radius (into the Radial Notch of the Ulna)
Distal: Ulnar Notch (with the Head of the Ulnar) |
|
|
What is another name for the wrist joint?
|
radiocarpal joint (an ellipsoid joint)
|
|
|
Which forearm bones and carpal bones form the wrist joint?
|
The radius, elipsoid articular disc and the carpals including: scaphoid, lunate and triquetrum.
|
|
|
What are the two parts of the coracoclavicular ligament?
|
trapezoid (more lateral, quadrilateral in shape)
conoid ligament (more medial, fan-like in shape) |
|
|
Which tendon enters the shoulder joint capsule?
|
Long head of biceps tendon
|
|
|
What movement of the clavicle does the costoclavicular ligament limit?
|
Stabilises the clavicle by limiting axial rotation of the medial clavicle (holds it against the 1st rib and prevents it from moving back, forward or up).
|
|
|
What is unusual about the coracoacromial ligament?
|
Because of its thickening at the margins, it forms a ligamentous arch which assists in stabilising the shoulder joint. Sometimes the pectoralis minor can insert into the shoulder capsule instead of the coracoid process, leading to the absence of the intermediate ligament portion as the tendon passes between the marginal bands.
|
|
|
How is the shoulder joint classified histologically and mechanically?
|
multiaxial synovial ball and socket joint
|
