Gather information on the structure and function of skeletal, cardiac and smooth muscle. Combine all this information to create a brief guide to the structure and function of vertebrate muscle. Points that you need to consider include cell shape; cell size; number of nuclei per cell; position of the nuclei; presence or absence of striations; presence or absence of branching; and presence or absence of intercalated discs. b) Follow the table with a one-sentence explanation of what an intercalated disc is. c) Briefly explain what happens to actin and myosin in muscle during rigor mortis.

Give the diagram of a sarcomere of skeletal muscle showing different regions?
Which of the following are aspects of the structure of skeletal muscle? Select all that apply. --They are cylindrical cells called muscle fibers that have multiple nuclei. --Skeletal muscle has more mitochondria than other types of muscle cells. --The muscle fibers parallel one another and have a striated appearance. --Cells are branched or unbranched with single nuclei. --Each fiber contains stacks of many units of contraction and protein filaments.
Distinguish between skeletal, smooth, and cardiac muscle in terms of location and whether they have sarcomeres. Use the sliding filament model to draw how thin filaments, thick filaments, and Z lines move during muscle contraction. Predict how perturbations of acetylcholine release, reception, or breakdown will influence muscle contraction. Predict how perturbations of actin, troponin, tropomyosin, myosin, or calcium would influence muscle contraction. Distinguish between the sympathetic and parasympathetic nervous system. Predict how changes in stress levels or situations would affect activation of the sympathetic and parasympathetic nervous system, levels of epinephrine and norepinephrine, and blood pressure.
