Question
Chapter 30, Problem 1CT
Summary Introduction
To determine:
If the presence of a certain type of chemical substances is enough evidence to support that the insects do feel pain.
Introduction:
Pain is an unpleasant and undesired sensation which may occur due to an organ or a tissue damage. There are various chemicals, which are released by damaged tissue. These chemicals act as stimuli, and the stimuli of pain are dependent on its duration, quality, location, and intensity.

After a leg injury, pain makes a person avoid putting too much weight on the affected leg. Shielding the injury gives it time to heal. An injured insect shows no such shielding response. Some have cited lack of such a response as evidence that insects do not feel pain. But insects do produce substances similar to our natural pain killers. Is the presence of these compounds in insects sufficient evidence to conclude that they feel pain?
Which of the following provides the most accurate example of active sensing being used by an animal?
Male moths use paired antenna to track the pheronome trail of a female moth
Electric fish detect the electric field of other nearby electric fish
Cats have a tapetum that enhances their night vision for hunting prey in the dark
Bats use echolocation to hunt flying insects at night
In the disease myasthenia gravis, the human body makes—by mistake— antibodies to its own acetylcholine receptor molecules. These antibodies bind to and inactivate acetylcholine receptors on the plasma membrane of muscle cells. The disease leads to a devastating progressive weakening of the people affected. early on, they may have difficulty opening their eyelids, for example, and, in an animal model of the disease, rabbits have difficulty holding their ears up. As the disease progresses, most muscles weaken, and people with myasthenia gravis have difficulty speaking and swallowing. eventually, impaired breathing can cause death. explain which step of muscle function is affected.

- Many neurotoxins have been used extensively in physiological studies of neurons. When comparing tetrodotoxin found in puffer fish and batrachotoxins from poison dart-frogs, the former had no effect on a neurons resting potential but completely stopped its action potential, whereas the later toxin immediately initiates depolarization of a neuron but prevents repolarization. Can your group hypothesize how these toxins affect the nerve transmission differently?arrow_forwardDuring a field trip, an instructor touched a moth resting on a tree trunk. The moth raised its forewings to reveal large eyespots on its hind wings. The instructor asked why the moth lifted its wings. One student answered that sensory receptors had fired and triggered a neuronal reflex culminating in the contraction of certain muscles. A second student responded that the behavior might frighten predators. Which statement best describes these explanations? A. The first explanation is correct, but the second is incorrect. B. The first explanation refers to proximate causation, whereas the second refers to ultimate causation. C. The first explanation is biological, whereas the second is philosophical. D. The first explanation is testable as a scientific hypothesis, whereas the second is not.arrow_forwardBirds play an important role in spreading seeds of chili plants. They readily spread chili seeds because the seeds (and capsaicin) do not produce pain in birds.

- Lidocaine is an anesthetic that is commonly used in medical and dental practices. After being injected or applied to the skin, lidocaine very quickly causes numbness in that area by affecting nerve transmission. Which option below is a possible mechanism by which lidocaine might work? Mimics the neurotransmitter released by sensory neurons Causes an influx of calcium into the axon bulb of sensory neurons Prevents the opening of sodium channels in the sensory neuronsarrow_forwardThe reflex arc is the fastest way the body has to move a body part from danger or away from the source of pain. Have you ever noticed your own reflex response? Did you notice that you felt the pain after you yanked your hand away from the source of pain? Which is the sequence of structures involved in a reflex response? a. motor neurons → effectors → brain → sensory neurons → interneurons b. effectors → sensory neurons → brain → motor neurons c. sensory neurons → interneurons → motor neurons → effectors d. sensory neurons → motor neurons → interneurons → effectorsarrow_forwardAlcohol addiction is a condition in which a person experiencesdependent on alcohol and difficult to control its consumption. On the other hand, excessive alcohol consumption in the long term can cause disturbances in brain performance, including disturbances in memory, attention, coordination, and locomotion. How does alcohol affect the functioning of nerve cells and the central nervous system? What is the mechanism that occurs? Based on information from the literature, analyze what will happen to coordination and locomotion in someone who is addicted to alcohol and consumes large amounts of alcohol over a long period of time.arrow_forward

- Taste buds are sensory receptors for taste located on the tongue. When a person eats a spicy food, receptors on the tongue pick up a stimulus. The stimulus initiates the movement of ions across the membrane. If the threshold level is reached, an action potential is generated and a signal is sent to the brain telling the brain that the food is spicy. The reason that some individuals have a higher tolerance to spicy food than others is due to a difference in the a. duration of the refractory period b. number of Na+/K+ ion exchange pumps c. strength of the stimulus d. threshold levelarrow_forwardAs light hits the rods and cones, they release molecules. This is interpreted as light by the brain. None of these is correct More neurotransmitter molecules More opsin molecules More rhodopsin molecules Fewer neurotransmitter moleculesarrow_forwardWhich of the following statements about sensory systems is NOT true? a. Sensory transduction involves the conversion (by either a direct or indirect mechanism) of a physical or chemical stimulus into changes in membrane potential difference. b. Sensory adaptation plays a role in the ability of organisms to discriminate between important and unimportant information. c. The term "sensory adaptation" refers to the process by which a sensory cell becomes less sensitive, or less responsive, to a continuing source of stimulation. d. In general, a stimulus causes a change in the flow of charged ions across the plasma membrane of a sensory receptor cell. e. The more intense a stimulus is, the greater the peak depolarization of the action potentials fired by the sensory neuron.arrow_forward
