Lecture 4 - SCAPULOTHORACIC JOINT Flashcards
(14 cards)
What is the SC joint?
Sternoclavicular joint
Multiaxial arthrodial
Not a true joint
What is the AC joint?
Acrmioclavicular joint
Arthrodial
What is the ST joint?
Scapulothoracic joint
Not a true synovial joint
What is the degree of movement for:
- Protraction - retraction
- Lateral-medial rotation
- Elevation- depression
- 25 degrees protraction - retraction
- 60 degrees lateral - medial rotation
- 55 degrees elevation - depression
What is the main focus of the shoulder girdle muscles?
Stabilize scapula
What are the 5 branches of nerves that supply the shoulder girdle?
- Axillary nerve
- Radial nerve
- Musculocutaneous nerve
- Median nerve
- Ulnar nerve
