  7. The supeficial inguinal ring has two crura
    medial and lateral crura
  8. The medial ________ of both superficial inguinal rings are very close.
  9. The stomach is found where in the abdominal cavity?

  11. The cranial (parietal) surface of the stomach makes contact with the _____ and ______.
    Diaphragm and left lobe liver.
  12. True or False. The stomach is inaccessible by rectal palpation or through flank incision.
  13. The ___________ divides the proximal nonglandular stomach from the distal glandular stomach.
  14. Where and how does the esophagus enter the stomach?
    Enters the lesser curvature obliquely at the cardia: Cardiac sphincter is very thick and effective (which is probably why horses cannot vomit)
