: Back: Skeleton, Muscles, Function - True/False
: 1. The atlas and the axis primarily mediate flexion/extension and rotation respectively.
: 2. Muscle of the suboccipital region attach near the inferior nuchal line and trapezius inserts along the superior nuchal line.
Agreed? is the question worded correctly?
: 3. Movement of the scapula toward the spinous process demonstrates protraction of the scapula.
: 4. Upward rotation of the scapula is mostly achieved by the supraspinatus and deltoid muscles.
Disagree, Trap and Serratus Ant.
: 5. Latissimus dorsi, but not teres major, provides downward rotation of the scapula.
: 7. Serratus anterior acts to retract and upwardly rotate the scapula.
: 8. A transverse line across the iliac crests intersects the L3/4 vertebral space.
: 9. The iliolumbar ligament connects the iliac crest to the L4/5 vertebrae.
: 10. The spinous processes of the thoracic vertebrae are distinguished by bifid processes.
Disagree, c4-7 have bifid processes also.
: 11. Generally, the medial branches of dorsal rami are sensory and the lateral branches are motor.
: 12. The greater occipital nerve passes through semispinalis capitis and trapezius, but not splenius wapitis.
Agreed as long as Wapitis is referring to capitus
: 13. The dorsal ramus of C1 does not have a cutaneous distribution.
Agreed, purely motor.
: 14. Inferior the to the superior nuchal line the occipital artery is medial to the greater occipital nerve.
: 15. Latissimus dorsi inserts at the floor of the intertubercular sulcus between the insertions of pectoralis major and rectus major wapitis.
: 16. Upper and lower fibers of trapezius insert medial and lateral on the scapular spine respectively.
Disagree, vice versa
: 17. Trapezius and serratus anterior primarily participate in the first 60 degrees of abduction of the upper limb.
Disagree, supraspinatus and deltoid
: 18. Rhombiodius major and minor are both innervated by the suprascapular nerve.
Disagree, dorsal scapular n.
: 19. Erector spinae muscles are innervated by dorsal rami and serratus posterior/inferior are innervated by ventral rami.
Agreed, (Ventral rami are intercostals correct?).
: 20. Serratus posterior superior assists in inspiration by way of raising the sternum (pump handle).
