. How might examination of the bulbar and palpebral portions of the conjunctiva be useful as part of the overall physical examination of an animal?
|
: The transparency of the conjunctiva allows the underlying tissues to show through, so it can be used as a window to see the blood vessels that are hidden elsewhere in the body by opaque structures, such as the skin. By looking through the conjunctiva at the lining of the eyelid, we can often detect abnormalities such as anemia (pale color caused by decreased blood flow), jaundice (yellowish color) and cyanosis (dark purplish color

|
An animal can intentionally blink its eyelids. Can it intentionally cover its eye with its third eyelid? Why or why not
|
No muscles attach to the third eyelid. Its movements are entirely passive
|
|
How would an animal with a plugged nasolacrimal system appear? Why?
|
If the nasolacrimal system were plugged, tears would be “spilling” out of the eyes because they would have nowhere to drain.
|
|
If the medial rectus muscle of an animal’s eye was damaged and lost its ability to contract, what would the effect be on the positioning of the affected eye? Why?
|
If the medial rectus muscle was unable to contract, the animal would not be able to rotate that eyeball toward midline, because this muscle originates from a small area around the optic canal and fissure and inserts on the medial side of the sclera (near the 9 o’clock position if you are standing in front of the animal).
