nictitate

In South America, a burrowing rodent, the tuco-tuco, or Ctenomys, is even more subterranean in its habits than the mole; and I was assured by a Spaniard, who had often caught them, that they were frequently blind; one which I kept alive was certainly in this condition, the cause, as appeared on dissection, having been inflammation of the nictitating membrane.

Reid considers it to be the effect of inflammation in the nictitating membrane.

Corneoscleral junctions are affected most frequently but involvement of eyelids, conjunctiva and nictitating membrane is also reported in some cases (Perino et al., 1993).

I can't answer your question, Bev, but I bet if you titillated by nictitating, you could wear out the T on your keyboard quickly.

Birds have upper and lower eyelids and a nictitating membrane (or third eyelid).

Beavers also have a third, transparent eyelid (called a nictitating membrane) that protects their eyes as they swim underwater.

When the retractor bulbi muscle contracts, the nictitating membrane (third eyelid) is closed as a protective mechanism (Fig.

An additional bone in the sclera of the eyes of owls and the common potoo (Nictibius griseus) and its role in the contraction of the nictitating membrane.

To prevent this, a nictitating membrane, sometimes referred to as a bird's "third eyelid," closes an instant before impact, keeping the eyes securely in their sockets and preventing any wood chips from damaging the eyes.

The nictitating membrane is found on which part of animal's body?

The toad repeatedly blinked and drew its nictitating membranes across its eyes (Fig.
