Here are a few anatomy questions to test your brain. Any ideas/references? 1) A plain radiograph of a pt following a knife wound to the left side of his neck showed elevation of the left hemidiaphragm, narrowing of the left intercostal spaces, and displacement of the trachea to the left. You suspect: A. hemothorax due to the blood from the wound B. pneumothorax due to the knife penetration of the cervical pleura C. transection of the phrenic nerve D. transection of the sympathetic trunk E. pleurisy I am trying to decide between A and C. The elevation of the hemidiaphragm makes me lean toward C, but I do not know if transection of the phrenic will cause the other 2 findings. 2) The semispinalis capitis: A. is part of the erector spinae group of muscles B. when acting unilaterally, rotates the head so that the face points to the ipsilateral side. C. when acting bilaterally, flexes the neck D. is innervated by cervical and upper thoracic posterior rami E. is superficial to the splenius capitis I think it is B, but some of my classmates think it is D. However, I think it is only innervated by the cervical posterior rami, not the thoracic. 3) In examining a newly pregnant woman, you notice that the spinous process of the L5 vertebra is abnormally prominent compared to the spinous processes of the superior lumbar vertebrae. You suspect: A. fracture of the body of L5 B. spondylolisthesis C. a vertebral canal tumor D. spina bifida E. kyphosis I am not really sure on this one. Best guess is B. I know that causes anterior displacement of the vertebral body, but I do not know if it affects the SP. 4) Which of the following is incorrect pertaining to the scaphoid? A. It articulates with the radius. B. it is the most frequently fractured carpal bone. C. Fracture is accompanied by pain along the lateral side of the wrist. D. A complication associated with fracture is avascular necrosis. E. It attaches to the flexor retinaculum. These answers seem like they all are correct, but I think the least correct is C. There is pain when pressure is placed on the anatomical snuff box, and it usually feels like a deep discomfort on the lateral side of the wrist. 5) Which of the following is incorrect pertaining to the cervical plexus? A. it innervates the omohyoid, sternohyoid, and sternothyroid B. it innervates a muscle that turns the head C. it provides sensory innervation to some of the face D. it provides sensory innervation to some of the scalp E. it provides sensory innervation to some of the shoulder. I have found references that indicate all of these choices as correct, unless if the skin over the parotid gland is not considered part of the face? If anyone has any ideas, I would greatly appreciate it!
