Question
Chapter 16, Problem 3DYKB
Summary Introduction
Introduction:
Conjunctiva is a protective layer. It exhibits defense mechanisms to protect the eye. Any microbial invasion results in impaired functioning and inflammation of this protective sheath. This condition is termed conjunctivitis.

- Jill is diagnosed with sensorineural deafness, a disorder in which sound waves are transmitted normally to the inner ear but they are not translated into neural signals that travel to the brain. Sometimes the cause is a problem with the auditory nerve, but in Jills case it has to do with a problem in the inner ear itself. Where in the inner ear is the disruption most likely to be located?arrow_forwardFigure 36.5 Which of the following statements about mechanoreceptors is false? Pacini corpuscles are found in both glabrous and hairy skin. Merkel’s disks are abundant on the fingertips and lips. Ruffini endings are encapsulated mechanoreceptors. Meissner’s corpuscles extend into the lower dermis.arrow_forwardWhich of the following is TRUE for hearing? the organ of Corti sits on top of the vestibular membrane the stapes is connected to the round window the stereocilia of the hair cells of the organ of Corti are connected to the basilar membrane the cochlear duct is located between the vestibular and the basilar membranesarrow_forward
- The sensory contex is the area of your brain that processes sensations from your body. Each section of the sensory cortex processes information from a different body part. Larger body parts, such as you back or thighs, do not necessarily receive more space the sensory cortex. Explain why larger areas of your body such as your stomach back or thighs do not have a large space in the sensory cortex of the brain and why is it important that these areas cannot distinguish minor sensations.arrow_forwardSensory receptors for the kinesthetic senses are located in the thalamus. embedded in the small bones in the inner ear. located in the spinal cord. embedded in muscle fibres and joints.arrow_forwardMeniere's disease is a disorder of the inner ear that may be due to an increase in the amount of endolymph. What would be some symptoms of this disease? Since the disease affects the inner ear and endolymph, it would probably limit the ability to equalize pressure and cause pain. Since the disease affects the inner ear, it would probably cause nausea and migraines. Since the disease affects the inner ear, it would probably cause issues with taste. Since the disease affects the inner ear, it would probably cause issues with balance and a sensation of vertigo. It could also cause hearing loss if it affected the cochlea.arrow_forward
- When Maddie’s physician examines her ear, he explains to her parents that she has a perforated eardrum. Which of the following statements is NOT true? Maddie is at higher risk for ear infections due to the perforation. Maddie’s eardrum will likely heal on its own and she will not need surgery. A perforated “eardrum” means that there is a tear or hole in Maddie’s tympanic membrane. Maddie has sensorineural hearing loss due to the perforated eardrum.arrow_forwardUnilateral Cerebral strokes can cause deficits in motor control, somatic sensation and vision. However, they do not cause deficits in hearing. The explanation for this is: Auditory information does not reach the cortex Auditory information only goes to one hemisphere. Auditory information goes to both hemispheres How are the outer segments of photoreceptors positioned? between bipolar cells and horizontal cells in the outermost layer of the retina in the ganglion cell layer farthest from the pigment epitheliumarrow_forwardSome people will listen to a record backwards and hear hidden messages. Because the phonemes are scrambled and not actually an encoded phrase, we can consider this an example of what quality of speech perception? Group of answer choices Heuristics, "Top down" processing, interpreting ambiguous stimuli Phonemic restoration Sound spectogram Formantsarrow_forward
- The bony wall found at the end of the middle ear has the three ossicles: malleus, incus and stapes tympanic membrane an oval window and a round window tectorial and basilar membrane Which layer of the retina is the nearest to light crossing the pupil? Ganglion cell layer Photoreceptor outer segments Outer nuclear layer Outer plexiform layerarrow_forwardWhich of the following statements about the corpus callosum is false? The corpus callosum is inferior to the cerebrum. The corpus callosum is anterior to the brainstem. The corpus callosum is lateral to the hippocampus. The corpus callosum is caudal to the olfactory bulbs.arrow_forwardgive the basic functioning of the following special senses: sight, smell, taste, and hearing. Then think about which sense you would miss the most if you lost it. Various medical conditions and situations can cause those senses to be blunted or lost entirely. Which sense do *you* feel would be most problematic to lose?.arrow_forward
