Morphological fiber types of retractor bulbi muscle in mouse and rat
Investigative Ophthalmology
|August 1, 1976
Abstract:
Retractor bulbi muscles of mouse and rat were examined by light and electron microscopy. Two morphological fiber types were observed, analogous to Type I and Type II cells of skeletal musculature and comparable to fibers observed in the global region of the rectus extraocular muscles of these species.
