Muscle is one of the four primary tissue types of the body, and the body contains three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle ().All three muscle tissues have some properties in common; they all exhibit a quality called excitability as their plasma membranes can change their electrical states (from polarized they contract rapidly, fatique quickly, use anaerobic (increased glycogen content) metabolism. Why do skeletal muscle cells appear striated? Muscle tissue is classified into three types according to structure and function: skeletal, cardiac, and smooth ( Table 4.2 ).

Tension is sensed when relay info from muscle spindles and the golgi tendon organs to the CNS. filaments containing actin and myosin (enable muscles to contract), has very large cylindrical cells (muscle fibers); striated; many nuclei found along the edge of the cell, repeated banding pattern found inside the cell, attached to bones by tendons; skeletal muscles, striated; cells are small and branched; one nucleus; cells are joined by intercalated disks, seen in cardiac muscle, help connect branched fibers of muscle tissue; helps signalize cell to cell, non striated; one central nucleus; cells packed together to form sheets; small and tapered on both ends, nuclei randomly distributed throughout in smooth muscle, dense regular nuclei are aligned parallel, involuntary body activities: churning of stomach and constriction of arteries, TBL 4: Frameworks for Health Promotion, Disea, Human Anatomy and Physiology Laboratory Manual, Elaine N. Marieb, Lori A. Smith, Susan J. Mitchell. Autonomic nerves function only to speed up and slow down heartbeat. What's that? Thin filaments attach to dense bodies on sarcollemma or in the cytoplasm instead of Z discs. Because skeletal muscle cells are long and cylindrical, they are commonly referred to as muscle fibers. In this simulation, you will explore the different muscle tissues in the human body and learn how muscle cells contract at the molecular level. contraction is slow and resistant to fatigue (uses less than 1% of ATP of skeletal muscle).

Intercalated discs join adjacent cardiac myocytes (*double check*) and adhering junctions occur on transverse sfc; attachment points for actin filaments of last sarcomere of myofibrils, desmosomes are on transverse sfc, and gap junctions are on the longitudinal surface. Finally, build the deadly organism by building 4 cells representative of each basic type of animal tissue: neural, epithelial, muscle and connective tissue. Satellite cells are immature myoblasts and are below the external lamina. It is formed by groups of smooth muscle cells interconnected by gap junctions which allow the transmission of action potentials between cells meaning motor neurons can stimulate more than one cell simultaneously. Myofilaments are smallest and myofiber is largest. Stronger contraction of a muscle requires recruitment of more motor units.
