rs Communication. Control and Integration CASE STUDY Kelly had been having difficulty focusing her eyes for a couple of weeks. She assumed her recent lack of sleep was the cause. But when she started dropping her keys and feellng unsteady when walking down the stairs, she became worried enough to go to the doctor. After the results ol several tests were known, the doctor told her she had myasthenla gravis. This is a disease in which the body’s own white blood cells start attacking acetylcholine receptors. 1. What’s the connection between acetylcholne and Kelly’s symptoms? a. Acetylcholine is a hormone released during stress b. Acetylcholine is found primarily in sensory neuron Connections c. Acetylcholine is found primarily in motor neuron connections d. Acetylcholine affects communication primarily with smooth muscles er Summary 2. lllhe blinding of acetylcholine opened sodium ohannels on the postsynaptic membrane, this would cause a temporary a, depolarization; excitatory postsynaptic potential b. hyperpolarization; excitatory postsynaptic polential c, depolarization; inhibitory postsynaptic potential d. hyperpolarization; inhibitory postsynaptic potential Some muscle relaxants used during surgery bind to acetylcho- line receptors, effectively blocking the action of acetylcholine just as in myasthenia gravis. The drugs (anticholinesterases) used after surgery to reverse the relaxants are the same as those used to treat myasthenia gravis. 3. What do you think the action of these drugs would be? a. Blocking the release of acetylcholine b. Blocking the action of acetylcholinesterase c. Increasing the production of choline d. Increasing the action of acetylcholinesterase To solve a case study, you may have to refer to the glossary NT or index other chapters in this textbook, A&P Connect, and other resources.
