Muscles of the Scapula Flashcards
1
Q
A
Levator Scapulae
Origin
- Transverse processes of the vertebrae C1-C4
Insertion
- Superior angle of the scapula
Action
- Elevation of the scapula
- Downward rotation of the scapula
- Assists in lateral flexion and extension of the head and neck
2
Q
A
Rhomboids
Origin
- Major Portion - Spinous Processes of Vertebrae T2-T5
- Minor Portion - Spinous Processes of Vertebrae C7 and T1
Insertion
- Major Portion - Vertebral Border from the Root of the Spine to the Inferior Angle
- Minor Portion - Root of the Spine of the Scapula
Action
- Retraction (adduction) of the scapula
- Downward rotation of the scapula
- Assists in elevation of the scapula
3
Q
A
Trapezius
Origin
- Trapezius Upper Section - Base of the Occiput, Ligamentum Nuchae, and Spinous Processes of C1-C7
- Trapezius Middle Section - Spinous Processes of C7-T3
- Trapezius Lower Section - Spinous Processes of T4-T12
Insertion
- Trapezius Upper Section - Lateral Clavicle and Acromion Process
- Trapezius Middle Section - Spine of the Scapula
- Trapezius Lower Section - Root of the Spine of the Scapula
Action
- All Three Sections - Upper Rotation of the Scapula
- Upper Portion - Elevation of the Scapula
- Middle Portion - Retraction (Adduction) of the Scapula
- Lower Portion - Depression of the Scapula
4
Q
A
Serratus Anterior
Origin
- Surface of the Upper 8 or 9 Ribs
Insertion
- Medial Border of the Scapula
- All Fibers Converge at the Inferior Angle of the Scapula
Action
- Protraction of the scapula
- Stabilize the scapula to the ribs
- Assists in upper rotation of the scapula
5
Q
A
Pectoralis Minor
Origin
- Ribs 3, 4, and 5
Insertion
- Coracoid Process of the Scapula
Action
- Depression of the scapula
- Downward rotation of the scapula
- Protraction (abduction) of the scapula
