SECTION 1: Structure of a Skeletal Muscle A. Layers of connective tissue separate a muscle into compartments. The layer called endomy- sium surrounds each muscle cell. Muscle cells are then bundled into fascicles, which are sur- rounded by perimysium. The entire muscle is composed of many fascicles, and is surround- ed by epimysium. All layers merge together to form the tendon that attaches the muscle to a bone. An outermost layer of connective tissue called fascia binds adjacent muscles together...

Which of the following statements about tissues is NOT true? Select one: a. Connective tissue consists of cells scattered throughout extracellular matrix that holds tissues & organs together and includes, cartilage, bone, and adipose tissue b. Muscle tissue includes striated/skeletal tissue that moves skeleton, cardiac tissue that controls heart contractions, and smooth tissue that line organs c.

Skeletal muscle cells have many nuclei per cell (i.e., they are multi- nucleate). What is the likely process, which results in this type of cell. Muscle cells lack the ability to separate chromosomes during! anaphase. Muscle cells undergo multiple rounds of mitosis for each pass through cytokinesis. Muscle cells undergo multiple rounds of S-phase during interphase. before entering G2. Muscle cells undergo multiple passes through cytokinesis for each pass through mitosis.
