skeletal muscle fibers are soft and surprisingly fragile. yet skeletal muscles can exert tremendous power—indeed, the force they generate while lifting a
weight is often much greater than that required to lift the weight. the reason they are not ripped apart as they exert force is that ( 1. ) tissue
bundles thousands of their fibers together, which strengthens and supports the muscle as a whole (figure 6.1).
each muscle fiber is enclosed in a delicate connective tissue sheath called endomysium (endo - mise - um). several sheathed muscle fibers are then
wrapped by a coarser fibrous membrane called ( 2. ) to form a bundle of fibers called a fascicle (fast - kul). many fascicles are bound together by
an even tougher \overcoat\ of connective tissue called an epimysium, which covers the entire muscle. the ends of the epimysium that extend beyond the
muscle (like the wrapper on a piece of candy) blend either into a strong, cord - like tendon or a sheetlike aponeurosis (apo - nu - rosis), which indirectly
attaches the ( 3. ) to bone, cartilage, or another connective tissue covering.
in addition to anchoring muscles, tendons perform several other functions. the most important are providing durability and conserving space. tendons are
mostly tough collagen fibers, so they can cross rough ( 4. ) projections, which would tear the more delicate muscle tissues. because of their
relatively small size, more tendons than fleshy muscles can pass over a joint. many people think of muscles as always having an enlarged \belly\ that
tapers down to a tendon at each end. however, muscles vary considerably in the way their fibers are arranged. many are spindle - shaped as just described,
but in others, the ( 5. ) are arranged in a fan shape or a circle (as described on pp. 202–203).

1. muscle 2. bony 3. fibers 4. connective 5. perimysium

Explanation:

1. Connective tissue bundles muscle fibers to strengthen them.
2. Perimysium wraps sheathed muscle - fibers to form fascicles.
3. Epimysium indirectly attaches the muscle to bone etc. through tendon or aponeurosis.
4. Tendons can cross rough bony projections.
5. Muscle fibers can be arranged in different shapes like fan - shaped or circular.
