Ligaments

where does the coracohumeral ligament attach?

attaches coracoid process to head of humerus

what type of joint is the GH?

ball and socket, synovial

Costcoclavicular ligament

connects clavicle to 1st rib costal cartilage

what 2 bones does the coracoclavicular ligament attach together?

corocoid process and clavicle

which joint is the costcoclavicular ligament associated with?

SC joint

what does the coracohumeral ligament do?

keeps the head of humerus in the glenoid cavity in standing position without using muscle contraction

what type of joint is the AC?

plane, synovial

what does the coracoclavicular ligament do?

prevents the scapula from being drive medially as long as the coracoclavicular ligament is intact, the acromion will NOT be drive below the clavicle

what type of joint is the SC?

saddle, synvoial

where do sternoclavicular ligaments attach?

they connect the manubrium of sternum to the clavicle (there are anterior and posterior parts)

What does the coracoclavicular ligament consist of?

1. Conoid part 2. Trapezoid part

ligaments of AC joint? (3)

1. acromioclavicular ligament - goes from acromion to lateral clavicle 2. coracoclavicular ligament (2 parts) - conoid - from coracoid process to conoid tubercle of clavicle - trapezoid - from coracoid process to trapezoid line of clavicle 3. coracoacromial ligament - doesn't provide stability but puts roof from coracoid to acromion

ligaments of GH joint?

1. capsular/GH ligament (3 parts) - superior: prevents downward movement of humeral head - middle: limits external rotation and anterior glide, especially in 45-60 degrees ABD - inferior: 3 parts - anterior band, posterior bad, axillary pouch... 2. coracohumeral ligament - attaches coracoid process to head of humerus...keeps the head of humerus in the glenoid cavity in standing position without using muscle contraction 3. transverse humeral - goes from greater tubercle to lesser tubercle, secures the long head of biceps in place

ligaments of SC joint (3)

1. sternoclavicular ligaments (anterior and posterior) - strengthen capsule 2. costcoclavicular ligaments - strong ligament, main stabilizing force for SC joint 3. interclavicular ligament - connects the 2 ends of the clavicle...goes over the manubrium.

all ligaments

AC - coracoclavicular, acromioclavicular SC - sternoclavicular, costcoclavicular, interclavicular GH - GH ligaments, coracohumeral, coracoacromial?

what does the costcoclavicular ligament do?

limits the amount of elevation that can occur at the SC joint
