Textbook Question
Chapter 15, Problem 3TC
Some sensory receptors, such as those for taste, smell, and pressure, readily undergo the process of sensory adaptation, or decreased response to a stimulus. In contrast, receptors for pain are less prone to adaptation. Why does this make good biological sense? What do you think happens to children who are born without the ability to feel pain normally?

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.
The sensory systems are complex and have the amazing ability to respond to different types of environmental stimuli. What is one aspect of the sensory systems we have looked at (gustatory, olfactory, or visual) that you found particularly interesting and would like to know more about?

- Receptors within the olfactory epithelium in the nasal cavity project to the glomeruli, which project to the mitral cells, which project as cranial nerve one to the pyriform and the entorhinal cortex located in the anterior and medial temporal lobe. What's odd about this sensory pathway, unlike other sensory pathways? Select one: a. it does not show sensory adaptation b. there is no thalamic nuclei processing olfactory infomation prior to processing in the primary cortex c. loss of smell can be a result of damage to the temporal lobe or damage to the olfactory receptor cells d. it processes information ipsilaterally e. the primary olfactory cortex is not part of the telencephalonarrow_forwardIn the process of sensory coding Recruitment of additional neurons occurs with a weak stimulus in order to make the stimulus stronger. 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_forwardAn example of a sensory neuron is one that leads from a pain receptor in the finger to the spinal cord. A pin can be pressed against the skin without eliciting a response from the pain receptor. However, if the pin is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly withdrawn through a reflex arc. How do we sense different types of pain (very painful vs. not painful at all)? Using what you understand about threshold potentials and the all-or-none principle, explain how it is possible to sense different levels of pain. question is in boldarrow_forward
- 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?arrow_forwardEnvironmental 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 areaarrow_forwardPain Undergoes little, if any, sensory adaptation. Why do you think this is so important?arrow_forward
- When a person blinks, the part of the brain that interprets visual stimulation is suppressed. The spontaneous act of blinking is controlled by the area of the brain that controls involuntary movements such as breathing and blood pressure. To determine whether the lack of light or the act of blinking causes the suppression, scientists had subjects close their eyes and then placed a bright flashing light in their mouth to stimulate the photoreceptors in the eyes through the palate. Visual stimulation was still suppressed. So the photoreceptors in the retina were not stimulated even though they were exposed to light. This study demonstrated that when a person blinks, it is the act of blinking and not the absence of light that causes the suppression of visual stimulation. In the diagram above, identify the part of the brain that is suppressed during blinking and the part of the brain that controls involuntary, spontaneous blinking.

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.arrow_forwardTactile acuity refers to the minimum separation required between two objects for the brain to perceive them as two separate points. The Two-Point Discrimination test is one method used to measure tactile acuity. A two-pronged instrument such as a bent paperclip is pressed at various locations on the body. The distance between the two ends is increased gradually until the person feels two distinct points. This distance is then measured. The less the distance that two points can be perceived separately, the higher the tactile acuity of that area. When comparing the tactile acuity of various body parts, what have you concluded about the number of receptors in the palm of your hand relative to the number of receptors on your shoulder? a. The tactile acuity for the palm is higher than for the shoulders. Therefore, more receptors are found on the palm than on the shoulders. b. The tactile acuity for the shoulders is higher than for the palm. Therefore, more receptors are found on the…arrow_forward
