  3. Question 1 What is space A? Ethmoidal conchae Cornual Diverticulum Frontal Sinus What is space B? Gutteral Pouch Nasopharynx Spheno-palatine sinus A B

  4.  Incorrect  • No, this is not the EthmoidalConchae! • Here are the EthmoidalConchae • Try again!

  5.  Incorrect  • No, this is not the CornualDiverticulum! • This is only found in horned animals where there is a sinus extending into the horns. • Here is the CornualDiverticulumin a cow: • Try again!

  6.  Correct!  • Yes! This is the Frontal Sinus! • Here are some more examples. • Try part B

  7.  Incorrect  • No, this is not the Nasopharynx! • Here is the Nasopharynx • Try again!

  10. Question 2 This is a lateral view of a horse’s cheek teeth. The arrows point to space above the roots of the teeth; what is this space? Nasopharynx Ventral Conchal Sinus Maxillary Sinus Why is this space important in the horse? What other important structure is present here?

  11.  Incorrect  • No, this is not the Nasopharynx! • It is located much more caudally • Here is the Nasopharynx • Try again!

  12.  Incorrect  • No, this is not the Ventral Conchal Sinus. It does not communicate directly with the roots of the teeth. • Try again!

  13.  Correct!  • This is the Maxillary Sinus. It is important in the horse as the roots of the cheek teeth are embedded here, so serious dental disease can present signs of respiratory tract infection. Entering the Maxillary Sinus surgically can be used as a route for accessing the roots of the teeth. • Care must be taken when performing this procedure as the Infraorbital Nerve runs through the sinus and is vulnerable to damage. Do you want to return to the start or end the quiz?
