Answer
Answer: The perimysium. The is the middle layer of connective tissue that bundles muscle cells into fascicles of 10 to 100 fibers each.
Work Step by Step
There are three layers of connective tissue that extend from muscle fascia and surronud skeletal muscles. These are the epimysium, the perimysium, and the endomysium.
1.The epimysium, a layer of dense irregular connective tissue, surrounds the whole muscle.
2.The perimysium, also of dense irregular connective tissue, delineates muscle fascicles; it
surrounds 10 to 100 muscle fibers(cells) to form bundles.
3. The endomysium, the innermost layer, consists mostly of reticular tissue. It wraps and separates individual skeletal muscle fibers(cells).
