Name two special senses whose receptor cells are replaced throughout life, and two special senses whose receptor cells are replaced so slowly that there can be no functional regeneration.
Which of the following statements concerning the inner ear is TRUE?
Question 3 options:
a)
The bony labyrinth within the tempoal bone contains spaces for the semicircular canals and the cochlea.
b)
The fibers of the cochlear nerve are attached to hair cells in the semicircular canals to carry information about movements of the head.
c)
The frequency of sound waves as defined by their wavelengths are perceived as pitch and are measured in decibels (dB).
d)
The saccule and utricle are critical sensory receptors for interpreting language, distinct from other sounds.
You are watching the stars at night, and you never seem to be looking at the right spot to catch the brightest meteors. Which of the following might explain this?
a)Your fovea contains mostly cones; thus you see dim light especially well when looking right at it.
b)Your peripheral retina contains more rods, which are more sensitive to dim light than cones; thus objects in your peripheral vision appear brighter in dim light situations.
c)Detection of light depends mostly on its color rather than intensity; thus cones play a larger role in detection of light in dim light situations.
d) all of the above.
( well explain the correct answer and type answer).

- Presbycusis is an age-related hearing loss affecting individuals over the age of 65. Many affected individuals have difficulty understanding words because, although they may be able to hear the sound, they are unable to distinguish the exact words. This hearing loss is most noticeable at higher frequencies. Which of the following statements correctly describes an individual suffering from presbycusis? Select one: a. Individuals with presbycusis have damaged hair cells at the base of the cochlea, which is closest to the oval window. b. Increasing the volume of higher frequency sound allows individuals affected with presbycusis to hear better. O c. Individuals with presbycusis have damaged hair cells at the apex of the cochlea, which is farthest from to the oval window. Od. Decreasing the amplitude of lower frequency sound allows individuals affected with presbycusis to hear better.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_forwardWhich of the following CORRECTLY contrasts the stereocilia in the cochlea versus the stereocilia in the utricle? a). The stereocilia in the cochlea are surrounded by perilymph, whereas the stereocilia in the utricle are surrounded by endolymph. b). The stereocilia in the cochlea are surrounded by endolymph, whereas the stereocilia in the utricle are surrounded by perilymph. c). The stereocilia in the cochlea are embedded in a tectorial membrane whereas the utricle are embedded in a cupula.d). The stereocilia in the cochlea are embedded in a tectorial membrane whersas the stereocilia in the embedded in a cupula.arrow_forward
- Here you see an astigmatism illustration. Please explain why astigmatisms cause blurred vision in the context of our sense of sight. Please do not merely say “The light rays do not hit the focal point”. Please explain why that matters for the sense of sight.arrow_forward(Bonus) Deafness and hearing loss are a widespread issue. According to WHO, currently more than 1.5 billion people (nearly 20% of the global population) live with hearing loss. From what you learned about our auditory system, briefly explain what would happen to hearing in each of the following scenarios. (a) the tectorial membrane can't hold its position and is pushing onto the auditory hair cells constantly. (b) the auditory hair cells near the base of the cochlea are damaged and dead. (c) the endolymph potassium concentration is lower than normal. (d) the perilymph potassium concentration is lower than normal.arrow_forwardListed below are the various components of the olfactory transduction process: 1. Golf G-protein 2.

- please select all correct options In the eye A) contraction of the ciliary muscles decreases the curvature of the lens. B) lateral inhibition by horizontal cells increases visual contrast. C) there are more cones in the fovea of the retina than there are rods. D) the rods take less than three minutes to fully adapt to dim illumination. E) visual acuity is best at the optic disc.arrow_forwardThe correct pathway of activation (by sending neuronal signals) in the retina is bipolar cell - retinal ganglion cell - photoreceptor photoreceptor - retinal ganglion cell - bipolar cell retinal ganglion cell - bipolar cell - photoreceptor photoreceptor - bipolar cell - retinal ganglion cell O bipolar cell - photoreceptor - amacrine cellarrow_forwarda) Consider a patient who has been exposed to an ototoxic drug that has caused the death of the outer hair cells in the cochlea but has left the inner hair cells unaffected.
