Problem 31
Step by step
Solved in 2 steps
- Which of the special senses is based on the following events? Membrane vibrations cause fluid movements, which lead to bending of mechanoreceptors and firing of action potentials. a. taste b. smell c. hearing d. visionWatch this video (http://openstaxcollege.org/l/DanielleReed) to learn about Dr. Danielle Reed of the Monell Chemical Senses Center in Philadelphia, PA, who became interested in science at an early age because of her sensory experiences. She recognized that her sense of taste was unique compared with other people she knew. Now, she studies the genetic differences between people and their sensitivities to taste stimuli. In the video, there is a brief image of a person sticking out their tongue, which has been covered with a colored dye. This is how Dr. Reed is able to visualize and count papillae on the surface of the tongue. People fall into two large groups known as tasters and non-tasters on the basis of the density of papillae on their tongue, which also indicates the number of taste buds. Non-tasters can taste food, but they are not as sensitive to certain tastes, such as bitterness. Dr. Reed discovered that she is a non-taster, which explains why she perceived bitterness differently than other people she knew. Are you very sensitive to tastes? Can you see any similarities among the members of your family?Watch this video (http://openstaxcollege.org/l/pupillary) to learn about the pupillary reflexes. The pupillary light reflex involves sensory input through the optic nerve and motor response through the oculomotor nerve to the ciliary ganglion, which projects to the circular fibers of the iris. As shown in this short animation, pupils will constrict to limit the amount of light falling on the retina under bright lighting conditions. What constitutes the afferent and efferent branches of the competing reflex (dilation)?
- Sensory receptors are classified functionally according to the following criteria, except :-a- their location in the bodyb- the nature of tissues in which they are foundc- the nature of stimuli acting on themd- their connection with cerebral coretxWhich one of these correctly describes the location of the organof Corti?a. between the tympanic membrane and the oval window in theinner earb. in the utricle and saccule within the vestibulec. between the tectorial membrane and the basilar membrane inthe cochlear canald. between the outer and inner ear within the semicircular canalsWatch this video (http://openstaxcollege.org/l/occipital) to learn more about a transverse section throughthe brain that depicts the visual pathway from the eye tothe occipital cortex. The first half of the pathway is theprojection from the RGCs through the optic nerve to thelateral geniculate nucleus in the thalamus on either side.This first fiber in the pathway synapses on a thalamic cellthat then projects to the visual cortex in the occipital lobewhere “seeing,” or visual perception, takes place. This video gives an abbreviated overview of the visual systemby concentrating on the pathway from the eyes to theoccipital lobe. The video makes the statement (at 0:45) that“specialized cells in the retina called ganglion cells convertthe light rays into electrical signals.” What aspect of retinalprocessing is simplified by that statement? Explain youranswer.
- Maculae of vestibular apparatus are :-a- stimulated by movement of endolymph over their surfaceb- stimulated during standing upright but inhibited in the recumbent posturec- alter the pattern of their discharge by head tiltingd- contain otoconia that press on hair cells to initiate resting basal dischargeThe maculae of the utricle and saccule with their embedded otoliths and the semicircular canals _______. dectect changes in the rate at which the head is moving amplify soft sounds to improve hearing can only detect motion if the head moves at a constant velocityGeneral sensations :-a- originate from all sensory receptors of the bodyb- are mediated by somatic sensory fibers onlyc- include the sense of movementd- include the sense of equilibrium
- A sensorineural hearing loss results from impairment of which structure?a) Mobility of bony ossiclesb) First cranial nervec) Patency of external canald) Eighth cranial nerveA baseball player was accidentally struck on the bridge of his nosewith a baseball, resulting in fractures of several facial bones. Soonafter sustaining the injury, he noticed that he had lost his sense ofsmell. Explain how this probably happenedMs. Young feels deep pressure during a tooth extraction. Which type of sensory receptordetects this sensation? Explain your answer. A stroke in the primary motor area has caused Don to lose control over his skeletalmuscles on the right side of his body. What lobe of his brain was damaged? Explain youranswer. Sally has a brain injury; she knows what she wants to say but can't vocalize the words.What part of Sally’s brain is affected? Explain your answer. Wendy had a few alcoholic drinks, then found walking and maintaining her balance difficult.Which part of her brain was sedated by the alcohol? Explain your answer.
