In large groups of muscles, such as the quadriceps, anatomical regions may be designated as surface (closer to the skin), intermediate or deep (closer to the bone). The different regions may have different ratios of slow-oxidative to fast glycolytic fibers. Data for citrate synthase activity and tetanus frequency for different regions of the quadriceps are shown below. Which region probably has the highest proportion of fast glycolytic muscle fibers? Surface Intermediate Deep Muscle Muscle Muscle Citrate synthase activity 12 15 18 Tetanus frequency (Hz) 70 60 40 Surface Intermediate Deep

Shortly after a person dies, Ca2+diffuses out of the saroplasmic reticulum and the body becomes very still and rigid, a phenomenoncalled rigor mortis (rig′er mōr′tis). Given ATP’s role in myosin head movement, propose an explanation for rigor mortis.
Explain how the process of skeletal muscle excitation–contraction coupling demonstrates the general principle of physiology that controlled exchange of materials occurs between compartments and across cellular membranes.
Discuss the following statement: “The basal lam-ina of muscle fibers serves as a molecular bulletin board,in which adjoining cells can post messages that direct thedifferentiation and function of the underlying cells.”
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.
Contraction of both skeletal and smooth muscle is triggered by an increase in cytosolic Ca2+. Compare the mechanisms by which each type of muscle converts a rise in Ca2+ concentration into contraction.
Explain how a ligand can bind to a membrane-bound receptor in asmooth muscle cell and cause sustained contraction for a prolongedperiod without a large increase in ATP breakdown (needs a proper explanation and not just 2-3 lines)

During one cross-bridging cycle in striated muscle one ATP molecule is hydrolyzed. Explain the two times when the energy from this hydrolysis is used, and what “work” is done in each case.
While the sarcoplasmic reticulum of muscle was first described by nineteenth-century microscopists, its true significance was not ap-preciated until its intricate structure was revealed much later by the electron microscope. What could you tell a nineteenth-century microscopist to enlighten him or her about the structure of the sarcoplasmic reticulum and its role in the coupling of excitation and contraction?
What properties of fast glycolytic and slow oxidative fibersadapt them for different physiological purposes?
Contraction of both skeletal and smooth muscle requires the influx of Ca2+ into the cytoplasm. Compare and contrast the locations and functions of the molecules to which Ca2+ binds in these muscles and explain the steps that lead to cross-bridge cycling in each type. please answer me precise and relevant to the questions thanks
