Final answer:
Muscle fibers are organized into fascicles by the perimysium, individual fibers are wrapped by the endomysium, and groups of fascicles are encased in epimysium, which forms tendons that attach muscles to bones.
Step-by-step explanation:
In skeletal muscle, muscle fibers are neatly organized into bundles known as fascicles, which are surrounded by a type of connective tissue called the perimysium. These fascicles provide a means for the nervous system to control muscle movement by selectively activating specific muscle fibers.
Within each fascicle, the individual muscle fibers are wrapped in a delicate connective tissue known as the endomysium, which contains vital extracellular fluid and nutrients that are delivered through the bloodstream. Bundles of fascicles form the muscles we see and use, and these are each wrapped in yet another connective tissue layer called the epimysium. Together, these connective tissues extend to form a tendon, connecting muscle to bone and allowing for movement at the joints.
