The mucous membrane that lines the eyelids and is reflected over the anterior surface of the eyeball is the conjunctiva.
True
Researchers have found that retinal ganglionic fields are of two types: on center or off center.
True
The photoreceptor cells are sensitive to damage from light.
True
Both the cornea and the lens are vascular.
False
The optic disc is the location where the optic nerve leaves the eyeball.
True
Sour taste receptors are stimulated by hydrogen ions of acidic food substances.
True
The fluid contained within the membranous labyrinth is called perilymph.
False
The extrinsic eye muscle motor units contain only 8 to 12 muscle cells and in some cases as few as 2 or 3 muscle cells.
True
Retinal detachment always results in loss of vision.
False
The structure that allows equalization of the pressure in the middle ear with that outside the body is the external auditory meatus.
False
The bending of light rays is called reflection.
False
The anterior chamber of the eye is filled with vitreous humor.
False
The neural layer of the retina prevents excessive scattering of light within the eye.
False
In order for sound to reach the spiral organ (of Corti), the auditory ossicles must vibrate the oval window and set the endolymph in motion.
True
Sound is generally perceived in the occipital lobe of the cerebral cortex.
False
Light passes through the entire thickness of the neural layer of the retina to excite the photoreceptors.
True
Without a functioning crista ampullaris, the semicircular canals would not function.
True
Contraction of the ciliary muscle causes the lens to bend the light less.
False
