  1. 1What is in the middle ear?
    1. AAuricle
    2. BOssicles
    3. CCochlea
  2. 2Which of the following statements regarding the special senses (olfaction, gustation, audition, equilibrium, and vision) are CORRECT? (Select all that apply.)
    1. AOlfactory neurons are unique because they are bipolar neurons exposed directly to the external environment.
    2. BFacial nerve (CN VII) carries taste sensations from the posterior 1/3 of the tongue, while Glossopharyngeal nerve (CN IX) carries taste from the anterior 2/3.
    3. CBoth audition (hearing) and equilibrium (balance) rely on hair cells with stereocilia as their primary sensory receptors.
    4. DThe maculae of the utricle and saccule detect rotational/angular acceleration, while the crista ampullaris detects static equilibrium and linear acceleration.
    5. ESound waves in the inner ear ripple the basilar membrane, causing stereocilia to bend against the stationary tectorial membrane.
    6. FCones are highly sensitive and active in low light for night vision, whereas rods are responsible for sharp color vision in bright light.
    7. GThe optic disc is known as the "blind spot" because it completely lacks photoreceptors.
  3. 3A patient experiences a loss of taste specifically on the posterior third of the tongue. Which cranial nerve is most likely affected, and which papillae are primarily located in this region?
    1. ATrigeminal nerve (CN V); Filiform papillae
    2. BVagus nerve (CN X); Foliate papillae
    3. CFacial nerve (CN VII); Fungiform papillae
    4. DGlossopharyngeal nerve (CN IX); Vallate papillae
  4. 4During the process of hearing, what specific event constitutes the transduction of mechanical energy into an electrical nerve impulse?
    1. ARippling of the basilar membrane against the cupula
    2. BMovement of the staples against the oval window
    3. CBending of stereocilia against the tectorial membrane
    4. DVibration of the tympanic membrane against the malleus
  5. 5In the retina, axons from which cell type converge to form the optic nerve (CN II)?
    1. APhotoreceptors (rods and Cones)
    2. BBipolar cells
    3. CHorizontal cells
    4. DGanglion cells
  6. 6Which fluid is found within the cochlear duct (scala media) and is characterized by a high potassium concentration?
    1. AVitreous humor
    2. BPerilymph
    3. CEndolymph
    4. DAqueous humor
  7. 7A patient is unable to distinguish between different colors in bright light but has relatively normal vision in the dark. Which cell type is likely dysfunctional?
    1. AAmacrine cells
    2. BCones
    3. CRods
    4. DBipolar cells
  8. 8What is the primary role of the auditory (Eustachian) tube in the middle ear?
    1. AEqualize air pressure across tympanic membrane
    2. BProduce cerumen to protect the ear from infection
    3. CDirect sound waves towards the external auditory canal
    4. DAmplify sound vibrations via the ossicles
  9. 9Which component of the eye's vascular tunic (uvea) is responsible for regulating the amount of light that enters the posterior cavity?
    1. ASclera
    2. BChoroid
    3. CCiliary body
    4. DIris
  10. 10In the olfactory system, where do the axons of the olfactory neurons first synapse after passing through the cribriform plate?
    1. APrimary olfactory cortex
    2. BNasopharynx
    3. CThalamus
    4. DOlfactory bulb
