- For vertebrate photoreception, define: (a) photopigment; (b) photoreceptor; and (c) receptive field.arrow_forwardFigure 36.14 Cochlear implants can restore hearing in people who have a nonfunctional cochlea The implant consists of a microphone that picks up sound. A speech processor selects sounds in the range of human speech, and a transmitter converts these sounds to electrical impulses, which are then sent to the auditory nerve. Which of the following types of hearing loss would not be restored by a cochlear implant? Hearing loss resulting from absence or loss of hair cells in the organ of Corti. Hearing loss resulting from an abnormal auditory nerve. Hearing loss resulting from fracture of the cochlea. Hearing loss resulting from damage to bones of the middle ear.arrow_forwardWhich of the following statements correctly describes the process of hearing? Select one: a. The hair cells farthest from the oval window detect low frequency. b. The hair cells farthest from the oval window detect high pitch. c. The hair cells closest to the oval window detect low amplitude. d. The hair cells closest to the oval window detect high amplitude.arrow_forward
- Which one of the following statements about photoreception is true? a. Light detection is initiated by the absorbance of light (a photon) by a photopigment molecule. b. Light detection is synonomous with vision. c. Light detection is always initiated in a rod photoreceptor located in the retina. d. Only light in the visible range (between 400 and 700 nm wavelength) can be detected by animals. e. None of the above answer choices (neither A, nor B, nor C, nor D) is true.arrow_forwardWhich of the following statements explains why vision is less sharp in dim light than in bright light?a. Cones are more responsive in dim light.b. There are more rods than cones in the eye.c. Many rods converge on a single ganglion.d. The dilated pupil lets in more light than the lens can focus.arrow_forwardWhich of the following are correct? Which one or more? a. Auditory fatigue is the increase in threshold after exposure to a loud sound. Auditory adaptation is a reduction in response of the auditory receptors to a sound over time followed by a steady state. b. The change in auditory thresholds is independent of the intensity, but dependent on the duration of the loud sound. c. Exposure to loud sounds is unable to damage the hair cells in the inner ear and therefore cannot lead to a permanent threshold shift. d. Auditory adaptation is the increase in threshold after exposure to a loud sound. Auditory fatigue is a reduction in response of the auditory receptors to a sound over time followed by a steady state.arrow_forward
- Which of the following statements aboutphotopic vision is false?a. It is mediated by the cones.b. It has a low threshold.c. It produces fine resolution.d. It does not function in starlight.e. It does not employ rhodopsin.arrow_forwardWhich statement is FALSE? A. The basilar membrane fibers nearer the oval window are long and fluffy B. Sound signals are processed by the resonance of the basilar membrane before reaching the receptors C. Different frequencies of pressure waves in the cochlea cause specific places along the basilar membrane to vibrate, stimulating particular hair cells and sensory neurons. D. None of the choicesarrow_forwardHow do we localize where sound is coming from and which structures are responsible? Select all that apply: a. The auditory nerve communicates with the vestibular nuclei to process information about the body's location b. Medial geniculate nucleus processes visual stimuli to locate visual cues associated with the sound c. The hair cells simultaneously process information about frequency as well as the location the sound originated in d. Lateral superior olives respond to differences in the amplitude of sound waves from each ear e. Medial superior olives respond to differences in the time it takes sound to arrive in each eararrow_forward
- Which of the following provides an example of serial (rather than parallel) processing in the visual system? a. Visual information is sent from the retina, to the LGN, and then to the visual cortex. b. Rods and cones function simultaneously in the retina. c. The “what” and “where” streams in the visual association cortex work together. d. Processing of motion and shape inform each other.arrow_forwardThe macula in the utricle detects:a. rotation of the head to the right.b. very low frequency sound waves that we can feel but not hear.c. tilting of the head to one side.d. linear acceleration of the head in a vertical plane.arrow_forwardThe inner ear is responsible for both hearing and balance. One of the diseases affecting the inner ear is Meniere's disease. Affected individuals often experience vertigo, among other symptoms. Vertigo is a sensation that the surrounding is spinning or swaying in the absence of any body movement. Which of the following rows correctly identifies the affected structure and process in individuals experiencing vertigo? Select one: a. Structure Process Semicircular canals Rotational equilibrium b. Structure Process Semicircular canals Gravitational equilibrium c. Structure Process Organ of Corti Gravitational equilibrium d. Structure Process Organ of Corti Rotational equilibriumarrow_forward
