feedback1="'''Incorrect!''' The Jacobson's organ, or vomeronasal organ, is a sensory organ, but it is involved in chemoreception and not sound. [[Snake Special Senses|WikiVet Article: Snake Special Senses]]."

feedback1="'''Incorrect''' The columella, an ossicle, extends from the inner ear to the quadrate bone and may detect vibrations (low frequency sound between 150 and 600 Hz) from the ground through the jaw. [[Snake Special Senses|WikiVet Article: Snake Special Senses]]."
feedback3="'''Incorrect!''' The Jacobson's organ, or vomeronasal organ, is a snake 'special sense'. It forms part of the chemosensory system which is analagous to 'taste' [[Snake Special Senses|WikiVet Article: Snake Special Senses]]."
+
feedback3="'''Incorrect''' The parathyroids play a very important role in calcium metabolism. There are usually two pairs of parathyroid glands which measure about 0.5-1.0 mm in diameter and are located cranial to the heart. [[Snake Endocrine System|WikiVet Article: Snake Endocrine System]]."
feedback2="'''Incorrect!''' The Jacobson's organ, or vomeronasal organ, does not play a role in reproduction. It forms part of the chemosensory system in snakes which is analagous to 'taste' [[Snake Special Senses|WikiVet Article: Snake Special Senses]]."
+
feedback2="'''Incorrect''' The Jacobson's organ is not associated with the snake reproductive system.  Hemipenes, paired male copulatory organs, may have protuberances that help grip the female. The surface groove (sulcus spermaticus) is involved in the propulsion of semen. [[Snake Special Reproductive System|WikiVet Article: Snake Reproductive System]]."
feedback4="'''Incorrect!''' Also known as the vomeronasal organ, the Jacobson's organ forms part of the chemosensory system in snakes, not the endocrine system. Scent particles picked up from the surroundings by the tongue are conveyed to the palate, to pass up through a duct to the Jacobson's organ for 'tasting'.[[Snake Special Senses|WikiVet Article: Snake Special Senses]]."
+
feedback4="'''Incorrect''' The thyroid, which is under pituitary control, appears to play an important role in shedding and growth. Accidental surgical removal of the thyroid may increase shedding, which is the reverse to lizards. In some species it has been reported that thyroid extract administration inhibits moulting.
