: : Back: Skeleton, Muscles, Function - True/False

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