Chapter 23, Problem 14SA
Summary Introduction
To review:
Any two additional senses in animals and how they help the animals.
Introduction:
The five senses occurring in humans are sense of touch, taste, smell, sound and sight. Apart from these, animals have certain other senses that help them be more keen of the environment and improve their survival.

Students have asked these similar questions
Environmental input to different sensory systems affects different neuroanatomical pathways.
However, there is a basic, common pathway plan that most sensory systems share. Choose the
response option that best describes that plan.
receptors --> hindbrain --> midbrain --> cortical association area
receptors --> medulla --> hypothalamus --> frontal cortex
receptors -> spinal nerves --> midbrain --> temporal cortex
receptors >brainstem --> thalamus --> primary cortical area
Which is True and which is False?
The receptors that allow us to sense linear acceleration as our airplane takes off are located in the middle ear.
The human sensory homunculus devotes considerable space to the larger parts of the body, such as the torso and legs.
Athletes in contact sports like boxing and football readjust their sensitivity to pain, not just their attitudes.
Imagine you wake up to the smell of smoke, The sound of the fire alarm, the flashing lights of sirens, the acreage taste of smoke in the air. In other words, all your senses are reacting to this emergency. Your body goes into "flight or fight mode".
Question: in about two paragraphs, can you describe the sensory pathway that the sensory information from just one of these special senses takes to the brain to be integrated.
for example, if you were describing the smell of the smoke, how was odor detected? Which cranial nerves are involved? Where are those located? Where do they connect to the rest of the brain?

The larger the receptive field of a sensory receptor, the greater the expected acuity and the more accurate the two-point discrimination. Lateral inhibition of neighboring receptors resulting in a relative reduction of action potentials in the neighboring second order neurons would be expected to increase acuity. A receptor potential that remains suprathreshold into the absolute refractory period will result in additional action potentials.arrow_forwardWhat mechanistic and functional differences distinguish the electric sense of sharks and rays from the electric sense of weakly electric teleost fish such as Apteronotus and Gnathonemus?arrow_forward
- Include a 5-10 sentence explanation of how the ear senses sound and relays that data to the brain to interpret auditory information. Some pieces to consider: What path does the sound travel through the ear? What structures do the waves interact with? How does the signal travel to the brain? Where in the brain is the data processed? How does this sense change with age? What could cause deafness in humans (there are at least two major ways this can happen)?arrow_forwardA light signal activates a photoreceptor, which, in turn, activates a bipolar cell. Horizontal cells in the retina inactivate the surrounding bipolar cells. Which of the following is the correct sensory system property that this example is describing? Frequency coding Population coding Stimulus type O Lateral inhibition Receptor adaptationarrow_forwardThe volley theory of auditory information transfer is: When hair cells follow the waveform of stimulating sinusoids > 3 kHz Dependent on the organization of the basilar membrane Responsive with an AC component to low frequency tones An extraordinarily slow process Which of the following statements concerning photoreceptors is not correct ? cones produce colored images whereas rhods don't cones contain rhodopsin cones are less sensitive to light cones produce clear imagesarrow_forward
- Unilateral 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_forwardWhat is the difference between the sense of smell of a fish to the human sense smell? what about the sense of sight?arrow_forwardWhich receptor(s) are responsible for our ability for applying the appropriate amount of pressure to grip an object?

- Wearing eye glasses for a prolonged period of time and then not realizing they are on your head is best explained by what phenomenon? Stimulus transduction Phasic receptor potential Sensory adaptation Phasic somatoreception Hearing any of the Kardashians speak and thus wanting all forms of stimuli to stoparrow_forwardWhen two eyes were made to innervate the same tectum in frogs, the two eyes did not project in a topographic manner. each eye innervated mutually exclusive stripes of tectum. both eyes projected evenly over the entire tectum. two separate visual fields, one from each eye, were projected onto each half of the tectum.arrow_forwardWhy can tactile stimulus be localized in parts of our body better than other parts?arrow_forward
