Benign Paroxysmal Positional Vertigo is a disorder where some of the calcium carbonate crystals in the utricle migrate into the semicircular canals. Why does this condition cause periods of dizziness? a. The hair cells in the semicircular canals will be constantly activated. b. The hair cells in the semicircular canals will now be stimulated by gravity. c. The utricle will no longer recognize acceleration. d. There will be too much volume in the semicircular canals for them to detect motion.

The inner ear is responsible for both hearing and balance. One of the diseases affecting the inner ear is Meniere's disease. Affected individuals often experience vertigo, among other symptoms. Vertigo is a sensation that the surrounding is spinning or swaying in the absence of any body movement. Which of the following rows correctly identifies the affected structure and process in individuals experiencing vertigo? Select one: a. Structure Process Semicircular canals Rotational equilibrium b. Structure Process Semicircular canals Gravitational equilibrium c. Structure Process Organ of Corti Gravitational equilibrium d. Structure Process Organ of Corti Rotational equilibrium

Choose the structure that applies to each statement. More than one structure may apply to a statement, and a structure may be used more than once. a. anterior cavity j. ora serrata b. anterior chamber k. posterior chamber c. choroid l. pupil d. ciliary body m. retina e. ciliary muscle n. sclera f. ciliary process o. scleral venous sinus g. cornea p. suspensory ligaments h. iris i. lens 1. produces aqueous humor 2. structures that are part of vascular tunic 3. contains photoreceptors 4. controls the size of the pupil 5. drains aqueous humor from the anterior chamber 6. structures that are part of the fibrous tunic 7. most anterior part of the eyeball 8. anterior boundary of retina 9. attaches lens to ciliary body 10. changes shape to focus light on retina 11. location of aqueous humor 12. white, tough outer layer of eyeball
