PLEASE THE TOPIC I NEED IS ABOUT SPINAL ANATOMY AND BACK PAIN DONT ANSWER QUESTIONS THAT ARE NOT RELATED READ ABOUT THE INSTRUCTIONS LIKE FOR EXAMPLE NUMBER 170 IS A RELATED TOPIC ABOUT THE SPINE SO IM GOING TO MAKE A RATIONALE WHY LETTER A IS THE CORRECT NASWER NOT THE OTHER CHOICES : 170. Deep somatic pan is transmitted by: A. C fibers B. D fibers C. B fibers D. A fibers answer: A Rationale: LETTER A IS CORRECT BECAUSE C-fibers are small and unmyelinated fibers that are responsible for slow/chronic pain and general sensations of pain and temperature. while A-Delta fibers (Type 3) are responsible for fast/acute pain and temperature. then A-Beta fibers (Type 2) are responsible for motor innervation for extrafusal and intrafusal muscle fibers.

Casting probably won’t provide adequate visualization of am open wound or access for treatment of an open fracture D. Bone fragments is comminuted fractures wont provide adequate anchoring for a pin or plate E. Traction would reduce and immobilize the are securely, but would place patient at great risk of immobility complication answer: B 169. The following statements apply to the femoral nerve. EXCEPT: A. Proximal lesions will result on weakness of thigh extension but most prominently lose of knee flexion B. Sensory distribution include the anteromedial thigh and the anteromedial leg to the foot C. Most common syndrome involving this nerve is a painful mononeuritis which occurs in diabetics D. The quadriceps muscle atrophics quickly, the knee jerk is lost early E. Arises for L1 to L4 spinal roots, and innvervates the lilopsoas, sartorius and quadriceps fermoris muscle answer: A 171. The following statements are true of the ulnar styloid process. EXCEPT: A.

It is most easily palpated when the hand is radially deviated and the tendon is contracted answer: A 172. Upon inspection of the lumbar spine from the side, which of the following observations is not TRUE? A. If the spine exhibits an exaggerated curve, the anterior abdominal muscles may be weaken B. Increased lumbar lordosis may also be caused by a fixed flexion deformity of the hip C. An absence of the normal lordosis may suggest paravertebral muscle spasms D. Pelvis obliquity is evident when the two dimples overlying the posterior iliac spine directly above the buttocks lie along the same horizontal plane E. Excessive lordosis occasionally substitutes for the hip extension answer: D 173. At the atlanto-occipital joint, the head is balanced by the pull of neck extensor muscles. This is example of: A.
