Morphologic study of the musculature of the third eyelid in the cat (Felis catus).
The presence of smooth and striated muscles associated with protrusion or retraction of the feline third eyelid was investigated histologically in eight cats. Nine smooth muscle strands extending into the third eyelid are described and illustrated. No striated muscle fibers extending into or within the third eyelid were observed.
