Section Reference 1: 17.4 Hearing and Equilibrium Question type: Essay 53) Explain the process by which smell sensations are sensed and perceived. Answer: Difficulty: Medium Learning Objective 1: 17.1 Describe the olfactory receptors and the neural pathway for olfaction. Learning Objective 2: 17.1.2 Outline the neural pathway for olfaction. Section Reference 1: 17.1 Olfaction: Sense of Smell Solution: Odorant molecules dissolve in mucus secreted by the olfactory epithelium and bind to receptors on olfactory hairs, triggering a generator potential in the olfactory receptor cells. In some cases the binding activates a G protein in the plasma membrane that activates adenylate cyclase that opens sodium ion channels. If the generator potential is above threshold, action potentials are generated in the axons of the olfactory receptor cells (first-order neurons). These axons transmit impulses via cranial nerve I through the olfactory foramina of the cribiform plate and terminate in the olfactory bulbs, where they synapse with second-order neurons. Axons from these neurons form the olfactory tracts, which transmit impulses to the olfactory area in the temporal lobe. Other important brain areas that receive impulses from the olfactory tracts include the limbic system, the hypothalamus, and the orbitofrontal area. 54) Emily was very ill with an upper respiratory infection. Her roommate gave her some chicken soup to make her feel better. Neither Emily nor her roommate realized that the soup was too hot to eat until after Emily put a spoonful in her mouth. Now Emily says she cant taste anything. Why? When will she be able to taste again? Answer: Difficulty: Medium Learning Objective 1: 17.2 Describe the structure of gustatory receptors and the neural pathway for gustation. Section Reference 1: 17.2 Gustation: Sense of Taste Solution: Emily probably already had trouble smelling her food because of her infection. The hot soup probably damaged her taste buds, especially the ones on the front and sides of her tongue. Those taste buds are more sensitive to sweet, sour and salty tastes. The ones at the back of the tongue are sensitive to bitter tastes, and the ones in the throat are sensitive to umami tastes. The taste buds are epithelial tissues and should heal in a few days or so. When they do, Emily will be able to taste again. 55) List and briefly describe the three processes that are used by the eye to form a clear image of object on the retina. Answer: Difficulty: Medium Learning Objective 1: 17.3 Describe the structural and functional components of the eye and those of the vision pathway. Learning Objective 2: 17.3.2 Discuss image formation by describing refraction, accommodation, and constriction of the pupil. Section Reference 1: 17.3 Vision Solution: 1) Refraction involves bending light rays as they move through different media in the eye to eventually form a focused inverted image on the central fovea, 2) Accommodation of the lens for near/distance vision involves changing the shape of lens using the ciliary muscle to help focus light rays on retina, and 3) Constriction of pupil involves an ANS reflex that helps prevent scattering of light through edges of lens. 56) Deafness can occur for many reasons. Use your knowledge of the structure of the ear and the process of detecting sound, to propose a mechanism for how arthritis could cause deafness. Answer: Difficulty: Medium Learning Objective 1: 17.4 Describe the structural and functional components of the ear and those of the hearing and equilibrium pathways. Learning Objective 2: 17.4.2 List the major events in the physiology of hearing. Section Reference 1: 17.4 Hearing and Equilibrium Solution: Arthritis results when synovial joints are damaged and can no longer move freely. The joints between the ossicles, found in the middle ear, are synovial joints. If they became stiff from arthritis and their movements were limited, sound waves striking the tympanic membrane would not be efficiently transferred to the oval window of the cochlea. Without that transmission, the fluid in the cochlea cannot move the hair cells on the organ of Corti. If those hair cells do not move, no impulses relaying information about sound can be generated. 57) Differentiate between static and dynamic equilibrium. Describe the inner ear structures involved in receiving and transducing sensations involved in maintaining both types of equilibria. Answer: Difficulty: Medium Learning Objective 1: 17.4 Describe the structural and functional components of the ear and those of the hearing and equilibrium pathways. Learning Objective 2: 17.4.3 Identify the receptor organs for equilibrium, and describe how they function. Section Reference 1: 17.4 Hearing and Equilibrium Solution: Static equilibrium is the maintenance of body position relative to gravity. Dynamic equilibrium is the maintenance of body position in response to movement. Hair cells in the maculae of the utricle and saccule bend are used to detect changes that help maintain static equilibrium. Hair cells in the cristae of semicircular ducts are used to detect changes involved in maintaining dynamic equilibrium.
