| Term | Definition |
|---|---|
| 3 groups of back muscles (name insertion) | Superficial (insert to bones of upper extremity), Intermediate (Insert into ribs), Deep (involved in head, vertebral column) |
| Name 5 superficial, and the 3 bones they insert into | Trapezius, Latissimus Dorsi, Lavator Scapulae, Rhomboid Major, Rhomboid Minor. Insert into clavicle, scapula, humerus |
| Trapezius origin (4), insertion (2) | (O)medial part of nuchal line, ext. occipital protruberance, lirgamentum nuchae, spinous processes of c7-t12. (I)lateral third of clavicle, acromion and spine of scapula. |
| Trapezius action (3), innervation (3) | (A) upper fibers elevate scapula, Middle fibers pull scapula medially, lower fibers pull medial border of scapula downward. (I)Cranial nerve XI (accessory nerve), c3 and c4 sensory |
| Lat Dorsi origin (5), insertion (1) | (O) lower six thoracic, lumbar, sacral; posterior iliac crest, lower 3/4 ribs. (I)intertubercular (bicipital) groove of humerus |
| Lat Dorsi action (4), innervation (1) | extends, adducts, medially rotaes the humerus, raises body during climbing |
| Levator Scapulae origin (2), insertion (1) | (O) Transverse process of the upper 4 cervical vertibrae (I) Medial border of scapula |
| Levator Scapulae action (1), innervation (3) | (A) Helps stabilize, elevate, inferiorly rotate scapula (I) c3 and c4; dorsal scapular nerve |
| Rhomboid Minor origin (1), insertion (1) | (O) Lower part of the ligamentum nuchae and spinous processes of c7 and t1 (I) Both insert medial border of scapula |
| Rhomboid Minor action (1), innervation (1) | (A) Both stabilize, retract, inferiorly rotate scapula. (I) Both Dorsal scapular nerve |
| Rhomboid major origin (1), insertion (1) | (O) Spinous processes of t2-t5 |
| Rhomboid major action (1), innervation (1) | (A) Both stabilize, retract, inferiorly rotate scapula. (I) Both Dorsal scapular nerve |
| Intermediate Muscles (2) Insert where? accessories of what? | insert to ribs, accessories to respiration. Serratus Posterior superior, inferior. |
| serratus posterior superior origin (2), insertion (1) | (O)ligamentum nuchae, spinous processes of c7 -t2 or t3 |
| serratus posterior superior action (1), innervation (1) | (A)Elevates ribs (I)Intercostal Nerves |
| Serratus posterior invterior origin (1), insertion (1) | (O) spinous processes of t11 to l2 or l3 (I) lower 4 riibs |
| Muscle action (1), innervation (1) | (A) depresses ribs (I)Intercostal Nerves |
| Muscle origin (1), insertion (1) | |
| Muscle action (1), innervation (1) | |
| Muscle origin (1), insertion (1) | |
