D Fasciculation
O
Recently, it has been observed that several muscle diseases and disorders are linked to problems with triad structure and function.One such disorder is called malignant hyperthermia, a dire hypermetabolic response to certain inhaled anesthetics such as halothane. Muscles become very rigid due to excessive contraction (especially the masseter muscle), the body temperature spikes, andmuscles break down. Death is certain if not treated. Given the principal symptoms of malignant hyperthermia, what is its likely cause?Propose a theoretical mechanism for a treatment that would dampen the deleterious effects of this disorder.

- Calmodulin is found in smooth muscle cells and performs a similar function to troponin in striated muscle fibers. However, calmodulin not only gets activated by Ca2+ but also slows the release of Ca2+ from the sarcoplasmic reticulum. How might this difference relate to the different kinds of contractions smooth muscles do in comparison to striated muscles?arrow_forward3. Identify the structures in the image below.

D.arrow_forwardResearchers are working to understand a rare disease that affects the ability of the muscles to contract. They have identified that the disease is caused by abnormal gene expression leading to a relatively large intracellular space between the T-tubules and the terminal cisternae in the triad, which causes an interruption in the connection between the dihydropyridine (DHP) receptor and the ryanodine calcium channel. Based on this description of the morphology underlying the disease, which of the following problems would you expect in excitation-contraction coupling? An action potential would not be able to be transmitted down the T-tubule. Re-uptake of calcium would be blocked, leading to an increase in intracellular calcium. O The actin binding sites may continue to be blocked by tropomyosin even following an action potential along the sarcolemma. O All of the above. Only B and C.arrow_forward

- Tetanus is a disease caused by Clostridium tetani characterized by muscle spasms. Just like the toxin produced by Clostridium botulinum, this toxin produced by C. tetani interferes with muscle contractions.
