List two examples of gliding synovial joints
intercarpal, intertarsal
What is a synchrondosis?
Nonsynovial joint between two pieces of cartilage (epiphyseal plate)
What is a Syndesmosis?
Nonsynovial joint between fibrous tissue(sutures of the developing cranial vault)
What is a synostoses?
Joint between bone
What is amphiarthroses?
Joint containing both synovial and nonsynovial character (pubic symphysis)
Describe the synovial membrane
highly vascular connective tissue lining a joint capsule (not lining the artcular cartilage) it is the source of synovial fluid
joints can contain two types of nerve fibers, name them
pain and position sensors
Name an extracapsular ligament
coracoclavicular ligament and the fibular collateral ligament
Name an intracapsular ligament
ACL or PCL
What type of joint is the Sternoclavicular joint? (Syn or non syn) and type of movements
Synovial, multiaxial
What type of joint is the acoracoclavicular joint? (Synovial or nonsynovial)
Synovial
What types of movement are possible in the SC joint?
Vertical axis-retraction/protraction
AP axis-elevation/depression
Oblique axis-Medial and Lateral rotation (of inferior angle of scapula)
What are the ligaments of the SC joint?
Anterior and Posterior sternoclavicular ligaments
What injury is common at the AC joint?
Shoulder seperation
What two joints form the shoulder girdle?
SC and AC
What type of joint is the choracoclavicular joint?
Fibrous, syndesmosis
What are the two portions of the coracoclavicular ligament?
conoid and trapezoid
What bones does the coracoclavicular joint span and stablize?
Scapula (at the corocoid) and clavicle
What type of injury does the Coracoclaviculare joint prevent?
Shoulder seperation
What movements does the coracoacromial ligament allow?
None, it prevents superior dislocation of the humeral head
What are the movements of the shoulder joint by axis?
Vertical axis-lateral/medial rotation
AP axis-AB and ADduction
Transverse axis-Flexion/extension
What is the function of the glenoid labrum?
Surround glenoid fossa and deepen and widen it (improve stablity)
What is the extracapsular ligament of the shoulder joint?
Coracohumeral ligament
When does the Coracohumberal ligament provide strength?
When the arm is adducted. It has no ability to stabilize an abducted arm
What are the four muscles of the rotator cuff and their attachments?
Supraspinatus-greater tubercle along spine of scapula

Infraspinatus-greater tubercle to scapula alogn inferior edge of spine

Teres minor-greater tubecle to medial scaula inferior to infra spinatus

Subscapularis-lesser tubercle (on anterior humerus to medial border of scapla on the anterior side
What are the two bursae of the shoulder joint?
Subacromial bursa and subdeltiod bursa
Where are the bursae of the shoulder joint located?
Subacromial-between the rotator cuff's superior margin and the acromion process
Deltoid bursa-lateral to subacromial bursa
What portion of the shoulder capsule is the most prone to tear?
Inferior
What type of shoulder dislocation is the most common?
anterior
What position results in an anterior dislocation?
Abducted, laterally rotated, and flexed (volley ball spike)
What type of joint is the choracoclavicular joint?
Fibrous, syndesmosis
What are the two portions of the coracoclavicular ligament?
