  3. Special Senses • The Eye Q1 • The Ear Q2

  4. The Eye Q1 Canine • (i) A makes up part of the Orbit. What is it? • Zygomatic Arch • Zygomatic Process • (ii) Which of the fossae, foraminae and fissures in the Orbit is connected, via a duct, to the nasal cavity? • Ethmoidal Foraminae • Lacrimal Sac Fossa • Orbital Fissure A Canine – Contrast showing duct in (ii).

  5.  Correct  Canine • Yes! A is the Zygomatic Arch! • The Zygomatic Process is the incomplete Zygomatic Arch in horses and ruminants. • Try (ii)! • Choose a new question. Zygomatic Arch Bovine Zygomatic Process

  6.  Incorrect  Canine • No, A is not the Zygomatic Process! • Remember: the Zygomatic Process is the incomplete Zygomatic Arch found in horses and ruminants. • Try again! • Choose a new question. Zygomatic Arch Bovine Zygomatic Process

  7.  Correct  • Yes! The Lacrimal Sac Fossa connects with the Nasolacrimal Duct! • Try The Ear Q2! • Choose a new question. Nasolacrimal Duct

  8.  Incorrect  • No, the Ethmoidal Foraminae do not connect with the nasal cavity. • Blood vessels and branches of the Ophthalmic nerve are found in the Ethmoidal Foraminae. • Try again! • Choose a new question.

  9.  Incorrect  • No, the Orbital Fissure does not connect with the nasal cavity. • The Orbital Fissure carries nerves and the ophthalmic vein. • Try again! • Choose a new question.

  10. The Ear Q2 • In this x-ray you can see the outline of the ear. • (i) Why is it not as white as the bones of the skull? • Answer. • (ii) What is A? • Tympanic Bulla • External Ear Cartilages • External Acoustic Meatus • (iii) What is B? • Tympanic Bulla • External Ear Cartilages • External Acoustic Meatus B A

  11. Answer • Normally, cartilage cannot be seen on an x-ray as it is softer and less dense than bone. • This x-ray would be described as ‘under-exposed’. This means that the soft tissue structures are more visible. • Try (ii)! • Choose a new question.

  12.  Correct  • Yes! A is the External Ear Cartilage! • It is not usually visible on x-rays as it is cartilage, not bone. • Try (iii)! • Choose a new question.

  13.  Incorrect  • No, A is not the Tympanic Bulla. • The Tympanic Bullae are shown in this x-ray. • Try again! • Choose a new question. Tympanic Bulla Tympanic Bullae

  14.  Incorrect  • No, A is not the External Acoustic Meatus. • The External Acoustic Meatus connects the External Ear to the Tympanic Bullae. • Try again! • Choose a new question.

  15.  Correct  • Yes! B is the External Acoustic Meatus! • The outer part, nearest the external ear, is cartilagenous; it is rarely visible on x-rays. • The inner part, as it approaches the Tympanic Bulla, is osseus; it can sometimes be seen in x-rays. • Choose a new question. External Acoustic Meatus

  16.  Incorrect  • No, B is not the External Ear Cartilage. • The External Ear Cartilages support the pinna of the Ear. • Try again! • Choose a new question. External Ear Cartilage

  17.  Incorrect  • No, B is not the Tympanic Bulla. • The Tympanic Bulla is found at the end of the External Acoustic Meatus. • Try again! • Choose a new question. Tympanic Bulla Tympanic Bullae
