Question
Chapter 33, Problem 4CT
Summary Introduction
To determine: Whether the compounds produced by insects that are similar to natural painkillers are a sufficient evidence to conclude that they perceive pain as mammals do.
Introduction: Pain sensation can be somatic or visceral based on its origin. It is perceived by the nociceptors that are peripheral sensory neurons. They respond to the stimuli such as tissue damage, high temperature, and others. They are present in both invertebrates and vertebrates though the pathways are different.

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?

- 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.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 However, if the pin is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly withdrawn through a reflex arc.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_forwardexamples are of pain blocking drugs are ketamine and propofol. Ketamine decreases the function of NMDA receptors and propofol increases the function of GABA receptors.
