Regarding the sensation of various species, which of the following statements is false?
A. The eyes of honeybees transduce parts of the electromagnetic spectrum that are invisible to humans
B. Bats ears transduce sound waves that humans cannot hear
C. Research has shown that the human eye transducers all of the electromagnetic spectrum to the brain, but the brain is unable to perceive it.
D. Sharks have special organs that can sense the bioelectric fields of other living things
Which 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.
Sensory pathways of smell and taste
a. are integrated with the advanced vomeronasal organ that humans possess
b. begin with chemoreceptors
c. begin in the somatosensory cortex
d. are not involved in communication

- Which 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_forwardWhen you exit a dark room into a brightly lit environment, within seconds, you to see a crisp view of your surroundings. However, when you enter a dark room from a brightly lit environment, your eyes might take more than 10 minutes to become used to the new surroundings. Your eyes are waiting for: a. the rods to begin to function b. the cones to begin to function c. the pupils to get smallerarrow_forwardWhat is meant by blindsight? a. Some people with damage to the primary visual cortex accurately guess the location or other properties of objects they say they don’t see. b. Blind people learn to find their way around by making sounds and listening for echoes. c. Blind people on average develop enhancements of hearing, touch, and other senses. d. After damage to the eyes, other body parts become sensitive to light. e. Incorrect hindsight.arrow_forward
- When you begin to move up or down in an elevator, you can still sense that you are moving even though there are no visual cues. Which sensory organ would be most responsible for detecting this? a. Merkel cells b. Pacinian corpuscles c. Otolith organs d. Semicircular canalsarrow_forwardWhat is the function of the three ossicles shown in blue (10, 12, 13)? ear with labels colorful.png a. amplify the motion created by sound waves hitting the tympanic membrane (ear drum) and conveying that to the labyrinth's little oval window, causing fluid to slosh inside the cochlea B . move when the tympanic membrane (ear drum) moves, creating pressure waves in the middle ear that feed down into the pharynx and combine with sound wave information from our jaws C. When the tympanic membrane (ear drum) moves, their mechanoreceptors are activated to send neural impulses to the brain about the sound wave intensities (loudness) D. they equalize the pressure inside the ear to protect the delicate sensory cells inside the inner eararrow_forwardInput to the human visual cortex comes from cones and rods (by way of ganglion cells) in what proportion? a. About 95 percent of input to the cortex comes from rods. b. About 50 percent comes from rods and 50 percent from cones. c. About 90 percent of input to the cortex comes from cones.arrow_forward
- Which 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_forwardThe transduction process of converting light into neural signals sent to the central nervous system involves which of these steps? A. Bipolar Cells collect signals from Rods and Cones. B. The Optic Nerve carries signals about light from the Lateral Geniculate Nuclues to the Retinal Ganglion Cells. C. Retinal Ganglion Cells relay information to Rods and Cones. D. Light that reaches the eyes passes first through the Retina which focuses that light onto the Cornea.arrow_forwardIf a person is born blind, in what way do the senses of hearing and touch improve? a. The person gradually develops more receptors in the ears and skin. b. The number of receptors does not change, but each of them becomes more responsive to weak stimuli. c. The receptors in the ears and skin send faster action potentials to the brain. d. Through practice the person learns to increase attention to hearing and touch, and those sensations come to activate the occipital cortex.arrow_forward

Each location in the auditory cortex responds to a preferred tone, and these areas are arranged in order from low pitches to high pitches. b. The auditory cortex has axons back and forth to every other part of the cortex and several nuclei of the thalamus. c. Each neuron in the auditory cortex has a distinctive pattern of responding depending on the location of the source of sound in space. d. Each cell in the auditory cortex has a “partner” cell in the visual cortex.arrow_forward
