ANATOMY

Detailed explanation-1: -Each skeletal muscle consists of thousands of muscle fibers wrapped together by connective tissue sheaths. The individual bundles of muscle fibers in a skeletal muscle are known as fasciculi. The outermost connective tissue sheath surrounding the entire muscle is known as epimysium.

Detailed explanation-2: -An individual skeletal muscle may be made up of hundreds, or even thousands, of muscle fibers bundled together and wrapped in a connective tissue covering. Each muscle is surrounded by a connective tissue sheath called the epimysium. Fascia, connective tissue outside the epimysium, surrounds and separates the muscles.

Detailed explanation-3: -The epimysium envelops entire muscles. Groups of muscle fibers are arranged in fasciculi that are separated by the perimysium, which is contiguous with the epimysium. The endomysium is a delicate network of connective tissue fibers, blood vessels, lymphatic vessels, and nerves that surrounds individual muscle fibers.

Detailed explanation-4: -The epimysium is a thick connective tissue layer that is composed of coarse collagen fibers in a proteoglycan matrix. The epimysium surrounds the entire muscle and defines its volume. The arrangement of collagen fibers in the epimysium varies between muscles of different shapes and functions.

Detailed explanation-5: -The interstitial connective tissue of muscle is subdivided into the epimysium (surrounds the entire muscle), perimysium (surrounds large angular fascicles divided into primary fascicles of 10–100 fibers), and endomysium (surrounds individual muscle fibers).
