PHYS 506 Anatomy and Physiology Muscle Histology MCQs Answers 2023/24 Muscle Histology 1. Skeletal and cardiac muscle, which are both striated, at resting length contain an A band in each sarcomere. This A band contains: (A)Essentially all the contractile protein myosin, but no actin (B) Essentially all the contractile protein actin, but no myosin (C) Essentially all the myosin, plus some actin (D)Essentially all the actin, plus some myosin (E) Troponin and tropomyosin, but no actin Ans...

What is the Muscle Cell? correct answers the muscle fiber Structure of a skeletal muscle correct answers a bundle of fibers - Epimysium - Perimysium - Endomysium - Fascicle -Sarcolemma - Muscle fibril - Myofibril Epimysium correct answers covers the entire skeletal muscle Perimysium correct answers surrounds fascicles Endomysium correct answers surrounds each muscle fiber Fascicle correct answers bundle of muscle fibers Sarcolemma correct answers Muscle's plasma membr...

The characteristics of muscle tissue excitability, contractility, extensibility, elasticity - specialized to contract - typically aggregated into bundles - elongated and arranged in parallel arrays - specialized cytoplasm = sarcoplasm - cell membrane = sarcolemma - modified ER = sarcoplasmic reticulum Know the histologic structure of a muscle and their connective tissue wrappings Can be striated or not, elongated, arranged in parallel arrays, typically aggregated into bundles -Endomysium → ...

Skeletal muscle - an organ specialized for contraction, composed of striated muscle fibers (cells), supported by connective tissue, attached to bone by a tendon or aponeurosis, and stimulated by somatic motor neurons Sarcomere - any of the repeating structural units of striated muscle Sliding filament mechanism - the explanation of how thick and thin filaments slide relative to one another during striated muscle contract to decrease sarcomere length Insertion - the attachment of a muscle t...
