- What is the calcium homeostasis process ?and what is the weakest tissue? .arrow_forwardImpairment of intracellular calcium homeostasis in muscle fibers lead to chronic, severe muscle dysfunction. Impaired Calcium ATPase activity can lead to abnormal, persistent elevation of intracellular calcium concentrations. Explain how persistently high intracellular calcium concentration would affect cross-bridge formation, and muscle contractions, and muscle tension? (Mention the effects on the steps involved cross bridge formation, and muscle contraction/relaxation cycle, and overall muscle tension).arrow_forwardIf calcium cannot be returned to the SR quickly after a muscle contraction, how would this affect muscle function?arrow_forward
- Suppose a person had an unusual mutation in the troponin protein of his skeletal muscles, such that the troponin could not bind to calcium. Would this person’s muscles be constantly contracted, constantly relaxed, or able to function normally? Explain.arrow_forwardWhat two types of muscle cells need both extracellular and introcellular calcium to contract? Skeletal muscle and smooth muscle Skeletal muscle and cardiac muscle Smooth muscle and cardiac musclearrow_forwardMr. White has cerebral palsy and suffers severe muscle spasms as a result of his condition. He is prescribed the drug dantrolene, which prevents the release of calcium ions from the SR. Explain how this will treat his muscle spasms.?arrow_forward
- A) tetany is rapid spasm in the muscle. B) Tetany is usually caused by an increase in the blood calcium levels.

Group of answer choices An increased frequency of action potentials would lead to decreased calcium levels in the SR A decreased frequency of action potentials would lead to decreased calcium levels in the SR An increased frequency of action potentials would lead to increased calcium levels in the SR A decreased frequency of action potentials would lead to increased calcium levels in the SR pick one answerarrow_forwardWhat cellular changes could cause the skeletal muscle to become rigid?arrow_forward
