False
True or false: The tongue is the sensory organ for taste.
True
True or false: Filiform papillae are one of the four types of papillae found on the tongue.
True
True or false: Gustation is one of the general senses localized in the skin and internal organs.
False
True or false: Olfaction is a special sense localized in the head region.
True
True or false: Taste buds contain three cell types: gustatory receptor cells, supporting cells, and basal cells?
True
True or false: The olfactory epithelium contains olfactory receptor neurons, supporting cells, and basal cells?
True
True or false: The olfactory glands produce mucus that dissolves odorants?
True
True or false: The olfactory nerve transmits information directly to the primary olfactory cortex without going through the thalamus?
True
True or false: Photoreceptors are the sensory receptors responsible for detecting light stimuli in the eye?
True
True or false: The lacrimal apparatus continuously cleans the anterior surface of the eye and prevents bacterial infection through the action of lysozyme?
True
True or false: The middle ear consists of a space spanned by three small bones called ossicles?
True
True or false: The inner ear is responsible for transforming mechanical waves into electrical signals?
True
True or false: The cochlea is a spiral-shaped tube divided into two compartments?

False
True or false: The fibrous tunic of the eye includes the white sclera and the clear cornea.
True
True or false: The vascular tunic of the eye is composed of the iris, ciliary body, and choroid.
True
True or false: The neural tunic or retina of the eye contains the photoreceptors involved in receiving and processing light.
True
True or false: The fovea centralis is the area of the retina that lacks supporting cells and blood vessels, resulting in the greatest visual acuity.
True
True or false: The optic disc, located at the posterior side of the eye, creates a blind spot in our vision.
True
True or false: Light passes through the vitreous humor and lands on the retina in the posterior cavity of the eye.
True
True or false: The otolithic membrane is a gel-like substance that the hair cells of the vestibule and semicircular canals extend into.
True
True or false: The otoliths are calcium carbonate crystals that are located on top of the otolithic membrane.
True
True or false: When the head moves, the otoliths remain stationary and do not move.
False
True or false: The hair cells within each ampulla are embedded in a region of the membranous labyrinth called the crista ampullaris.
True
True or false: The cupula is a gelatinous layer that the hair cells of the vestibule and semicircular canals extend into.
True
True or false: As the head rotates in a plane parallel to the semicircular canal, the fluid deflects the cupula in the same direction as the head movement.
False
