5 True/False Questions
Trigeminal Nerve 5 → fibers are found throughout face and transmit pain impulses; one of the highest concentrations of sensory nerve endings found in cornea. Reason cornea is so sensitive; causes blinking and tearing
Iris → colored diapghram of tissue and muscle that stretches over the back part of the vascular tunic; Primary = regulate amount of light entering eye
Anterior chamber → located along the floor of the orbit; 23 degree angle with medial wall of orbit; primary = depression; secondary= extortion and adduction; Oculomotor Nerve CNIII
Optic Tracts → bilateral groups of decussating fibers;
temporal retinal fibers from ipsilateral eye
nasal retinal fibers from the contralateral eye
Conjunctiva → the central, outermost anterior portion of fibrous layer; thin, strong transparent membrane made of five layers. Most powerful refractive structure in the eye. Second refractive media after the tear film.
