Shoulder and Pelvic Girdle Flashcards
What are the 3 bones that make up the coxal/innominate bone?
Pubis, Ischium and Ilium
What are the two joints of the pelvis?
The Pubic Symphysis and the Sacroiliac Joint
What are the three primary movements of the pelvis?
- APT/PPT
- Lateral Tilting
- Rotation
What spinal movements are typically associated with each pelvic movement?
- APT and Lumbar Extension
- PPT and Lumbar Flexion
- Lateral Tilt and the opposite lateral spinal flexion
- Rotation and the corresponding spinal rotation
What are the 3 types of bone in the shoulder girdle?
Scapulae, Clavicles, and Sternum
How many bones are there in the shoulder girdle?
5
what are the 5 bones of the shoulder girdle?
2 Scapulae, 2 Clavicles, 1 Sternum
What are the three joints of the shoulder girdle?
Sternoclavicular Joint
Acromioclavicular Joint
Scapuluthoracic Joint
What type of joint is the Sternoclavicular joint?
A fibrous saddle joint with small ROM
What type of joint is the Acromioclavicular joint?
A synovial plane/gliding joint with small ROM
What type of joint is the Scapulothoracic joint?
False or Gliding joint. Non-diarthrodial
What is the Glenoid Fossa?
A pear shaped fossa located on the lateral aspect of the scapula which acts as an articulating surface for the humerus
What is the Acromion process?
A palpable and bony prominance at the end of the scapular spine which acts as an articulating surface for the clavicle
What is the coracoid process?
a finger-like bony spur protruding from the anterior aspect of the scapula
What is the supraspinous fossa?
Fossa found on the dorsal aspect of the scapula, superior to the scapular spine
What is the scapular spine?
A raised ridge on the dorsal/posterior aspect of the scapula
What is the medial border of the scapula?
The border closest to the spine
What is the infraspinous fossa?
A fossa found on the dorsal aspect of the scapula, inferior to the scapular spine
What is the Origin, Insertion and Action of the Subclavius muscle?
- O: First Rib and Costal Cartilage
- I: Middle third of the clavicle
- A: Stabilises clavicle, brings down and forward
What is the Origin, Insertion and Action of the Pec Minor?
- O: Ribs 3-5
- I: Medial border and superior surface of coracoid process
- A: Scapular protraction and anterior tilting
What is the Origin, Insertion and Action of the Serratus anterior?
- O: Ribs 1-8/9
- I: Costal surface of medial border of scapula
- A: Scapular Protraction and upward rotation (along with lower trap)
What is the Origin of the Trapezius?
- Occipital bone: Superior Nuchal line and external occipital protuberance
- Ligamentum Nuchae
- C7-T12: Spinous process and intervening supraspinous ligaments
What is the insertion of the upper trap fibres?
Lateral aspect of the clavicle
What is the insertion for the middle trap fibres?
Medial border of the acromion and upper lip of scapular spine
