Scapular Anatomy

Superior Limbs

QuestionAnswer
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 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 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
