Describe the structure and function of a muscle fiber; summarize the process of muscle contraction. How contraction occurs in smooth muscle? How does muscle contraction happen? What is the role of actin and myosin in the process? Explain why the force of a muscle fiber's contraction is depen...
Describe the structure of the muscle fiber (cell) and the unique names given to its structures. Describe the structure of muscle tissue. Identify the structure from the given description: It occurs as tubules in kidneys. Describe the structural differences between a smooth and skeletal muscle ...
Although there are three types of muscle tissue with unique cell morphologies, the fiber bundles of each tissue type are arranged in parallel oriented on the long axis and are distinct from surrounding connective tissue. Muscle is classified according to the appearance of the contractile cells. ...

Rest state (before the skeletal muscle receives nerve impulses) The outer surface of the muscles fiber membrane is (+ ve) positively charged,The inner surface of the muscle fiber membrane is (− ve) negatively charged. Apotential differenceis formed, due to the difference in ions concentra...
Tropomyosin also binds to F-actin in smooth muscle and in non-muscle cells and stabilizes and regulates the filaments there in the absence of troponin6. Although crystal structures for monomeric actin (G-actin) are available7, a high-resolution structure of F-actin is still missing, hampering...
Membranous networks of channels and tubules in a muscle fiber, corresponding to the smooth endoplasmic reticulum of other cells. Transverse tubule Membranous channel that extends deep into the cell from a muscle fiber membrane; T-tubule. Cisterna ...
Cell membrane of a muscle fiber, surronds the sarcoplasm A change in membrane potential begins contractions Transverse Tubules (T tubules) Transmits action potential through cell Allows entire muscle fiber to contract simultaneously Myofibrils
Give differences between a muscle organ, a muscle fiber, myofibril, and a myofilament? Identify the structure from the given description: A bundle of muscle cells. Which of the following is striated? (a) cardiac muscle (b) smooth muscle (c) skeletal muscle (d) both cardiac and smooth...
