the eye q1
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).

correct
 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

incorrect
 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

correct1
 Correct 
  • Yes! The Lacrimal Sac Fossa connects with the Nasolacrimal Duct!
  • Try The Ear Q2!
  • Choose a new question.

Nasolacrimal Duct

incorrect1
 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.
incorrect2
 Incorrect 
  • No, the Orbital Fissure does not connect with the nasal cavity.
  • The Orbital Fissure carries nerves and the ophthalmic vein.

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

    • Tympanic Bulla
    • External Ear Cartilages
    • External Acoustic Meatus

B

A

answer
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.
correct2
 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.
incorrect3
 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

incorrect4
 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.
correct3
 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.

incorrect5
 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
