Scapular Anatomy
Superior Limbs
| Question | Answer |
|---|---|
| What are the scapular movements? | -Upward rotation, downward rotation, -retraction (adduction), protraction (abduction), -elevation, and depression |
| What do all the attachments have in common? | The 7 muscles that originated on the axial skeleton & inserts onto the pectoral girdle. |
| What is the main function of the attachments? | The main function of the attachments is to hold scapula in place & stabilize. |
| What muscles move the scapula Upward Rotation? | -Trapezius -Surratus Anterior |
| What muscles move the scapula Downward Rotation? | -Rhomboideus Major -Rhomboideus Minor -Levator Scapulae -Pectoralis Minor -Subclavius |
| What muscle Abducts the scapula? (Abduction) | -Pectoralis Minor -Serratus |
| What muscle Elevates the scapula? (Elevation) | -Levator Scapulae -Trapizeus |
| What muscle Depresses the scapula? (Depression) | -Trapizeus |
| Scapula, Humerus and Clavicle make the _________________ skeleton. | Apendicular |
| The apendicular skeleton is made if what 3 bones? | Scapula, Humerus & Clavicle |
| The sternum and the Vertebral make the ________________ skeleton. | Axial |
| The axial skeleton is made of what 2 bones? | Sternum and Vertebral |
| The sternalclavicular joint is the one spot that where the bones of the appendicular skeleton attach to the _____________________________. | Axial Skeleton |
| What 2 skeleton parts attach to the sternalclavicular joint? | Appendicular and Axial Skeleton |
| Is the upper limb weak? | YES |
| What is the ORIGIN of the Rhomboideus Major? | Spineus Process T2-T5 |
| What is the INSERTION of the Rhomboideus Major? | Medial Margin=The area below the Spine of the scapula) |
| What is the STRUCTURE and RELATIONSHIP of the Rhomboideus Major? | Deep to the trapezius and a small part is superficial. |
| What is the ORGIN of the Rhomboideus Minor? | Spineus Process of C7 and T1 |
| what is the INSERTION of the Rhomboideus Minor? | Medial Margin = At the spine of the scapula |
| What is the FUNCTION of the Rhomboideus Minor? | Adducts and downward rotates the scapula |
| What is the STRUCTURE and RELATIONSHIP of the Rhomboideus Minor? | Completely deep to the trapezius |
| What is the ORGIN of the Levator Scapulae? | Transverses process of the C1 - C4 |
| What is the INSERTION of the Levator Scapulae? | Superior angle (Side of neck) |
| What is the FUNCTION of the Levator Scapulae? | Laterally flexes neck, elevates scapula and downward rotates scapula |
| What is the STRUCTURE and RELATIONSHIP of the Levator Scapulae? | Deep to the trapezius |
| What is the ORGIN of the Trapizus Muscle? | External occipital protuberance, superior nochal lines, spineus process of C7 to T12 |
| What is the INSERTION of the Trapizus Muscle? | Spine of the Scapula, Acromion, lateral 1/3 of clavical |
| What is the FUNCTION of the Trapizus Muscle? | Elevates, upward rotates, adducts scapula, depression of scapula, extends head |
| What is the STRUCTURE and RELATIONSHIP of the Trapizus Muscle? | Superficial |
| What is the ORGIN of the Serratus Anterior? | Outer Surface of ribs 1-8 (Sometimes 9) |
| What is the INSERTION of the Serratus Anterior? | Medial margin |
| What is the FUNCTION of the Serratus Anterior? | Abducts and upward rotation of the scapula also forced breathing |
| What is the STRUCTURE and RELATIONSHIP of the Serratus Anterior? | Superficial on side deep under scapula, forms the medial wall of axilla |
| True or False; Is the surratus anterior located on the lateral thorax and forms the medial wall of the axilla. | True |
| What is the ORGIN of the Pectoralis Minor? | Ribs 3,4 & 5 |
| What is the INSERTION of the Pectoralis Minor? | Coracoid |
| What is the FUNCTION Pectoralis Minor? | Abducts and Downward rotates the scapula and forced breathing |
| What is the STRUCTURE and RELATIONSHIP of the Pectoralis Minor? | Deep to the pectoralis |
| What is the ORGIN of the Subclavius Muscle? | Rib 1 |
| What is the INSERTION of the Subclavius Muscle? | (Bottom of the clavicle) Conoid tubercle |
| What is the FUNCTION Subclavius Muscle? | Downward rotation and forced breathing |
| What is the STRUCTURE and RELATIONSHIP of the Subclavius Muscle? | Deep to the pectoral major |
| How do you stretch a muscle? | You stretch a muscle making it do the opposite of it's function |
| What is the FUNCTION of the Rhomboideus Major? | Only adducts and downward rotates the scapula |
| What muscle Adducts the scapula? (Adduction) | -Rhomboideus Major -Rhomboideus Minor -Trapezius |
