T1-GA-Lab UE Mus 4

QuestionAnswer
Origin of subscapularis? Subscapular fossa of scapula
Insertion of subscapularis? lesser tubercle of humerus
Action of subscapularis? Medial rotation and adduction of humerus
Innervation of Subscapularis? Upper and lower subscapular ns
Origin of Teres Major? Inferior angle of scapula (dorsal surface), lower third of axillary border of scapula
Insertion of Teres Major? Medial lip of bicipital groove of humerus
Action of Teres Major? Extension, Medial rotation, and Adduction of humerus
Innervation of Teres Major? Lower subscapular n
What muscle does Teres Major lie superior to? What do they form? Latissumus dorsi, and they form the posterior border of the axilla—share the same actions
What muscles work together to pull downward (stabilization) on the head of the humerus during abduction? infraspinatus, teres minor, and teres major
Origin of the Anterior Deltoid? Lateral third of the scapula
Origin of the Middle Deltoid? Acromion of scapula-lateral surface
Origin of the Posterior Deltoid? Spine of the scapula
Insertion of the Deltoids? deltoid tuberosity of the humerus
Action of the Anterior Deltoid? Flexion, Horizontal adduction, and medial rotation of humerus
Action of the Middle Deltoid? Abduction of humerus to 90 degress
Action of the Posterior Deltoid? Extension, Horizontal abduction, lateral rotation, and scaption of humerus
Innervation of the deltoids? Axillary n
What muscle initiates abduction of the humerus for the deltoids, and why? supraspinatus, and because the angle of pull
Origin of Serratus Posterior Superior? Ligamentum nuchae-caudal portion, C7-T3 vertebrae—spinous processes
Insertion of Serratus Posterior Superior? Ribs 2-5 superior border
Action of Serratus Posterior Superior? Elevation of ribs to increase thoracic cavity during inspiration
Innervation of Serratus Posterior Superior? Intercostal ns T1-4
Origin of Serratus Posterior Inferior? T11, 12, and L1-3 vertebrae-spinous processes
Insertion of Serratus Posterior Inferior? Ribs 8-12-inferior border
Action of Serratus Posterior Inferior? Depression of ribs outward counteracting the inward pull of the diaphragm during expiration
Innervation of Serratus Posterior Inferior? Intercostal ns T9-12
Origin of Serratus Anterior? Lateral surface of upper 8 ribs (by finger-like slips)
Insertion of Serratus Anterior? Vertebral border of scapula (anterior surface)
Action of Serratus Anterior? Abduction (protraction) and Lateral (upward) rotation of the scapula, Stabilizes scapula against chest wall, depression of scapula (lower fibers), assists in forced exhalation
Innervation of Serratus Anterior? Long Thoracic nerve
Weakness in what muscles causes “winged scapula? Serratus Anterior
What muscle does the serratus anterior interdigitate with? external obliques
Which muscle is the strongest abductor of the scapuls? serratus anterior
When the muscles of the humerus move it, what muscle counters and how? Serratus anterior, holds the scapula against chest wall to provide an origin for those muscles
Origin of Pectoralis Major? Clavicular head:medial half of clavical; sternocostal head:sternum, cartilages of superior 6 ribs, and abneuoris of external oblique muscles
Insertion of Pectoralis Major? Lateral lip of bicipial (intertubercular) groove of the humerus
Action of Pectoralis Major? Adduction, Horizontal adduction, and Medial rotation of the humerus. Clavicular head:flexion of the humerus; Sternocostal head: extension of the humerus, assists anterior tilt of scapula
Innervation of Pectoralis Major? Clavicular head:Lateral and medial pectoral ns (C5, 6) and Sternocostal head:medial pectoral n (C7,8, T1)
What muscle forms the anterior wall of the axilla? Pectorialis major
Origin of Pectoralis Minor? Anterior surface of ribs 3,4.5 near costal cartilages
Insertion of Pectoralis Minor? Coracoid process of scapula (medial border of superior surface)
Action of Pectoralis minor? Abduction (protraction), depression, medial (downward roation), and anterior tilt of scapula; assists in inhalation
Innervation of Pectoralis Minor? Medial pectoral n (C8, T1)
Origin of Subclavius? 1st rib costocartilage junction
Insertion of Subclavius? Inferior shaft of clavicle –middle 1/3
Action of subclavius? Depresses clavicle, and stabilizes sternoclavicular joint
Innervation of subclavius? Subclavian n
What prevents extreme elevation and protraction of the clavicle? Subclavius
