MICROANATOMY

Detailed explanation-1: -Skeletal muscle is one of the three significant muscle tissues in the human body. Each skeletal muscle consists of thousands of muscle fibers wrapped together by connective tissue sheaths.

Detailed explanation-2: -A whole skeletal muscle is considered an organ of the muscular system. Each organ or muscle consists of skeletal muscle tissue, connective tissue, nerve tissue, and blood or vascular tissue. Skeletal muscles vary considerably in size, shape, and arrangement of fibers.

Detailed explanation-3: -Answer and Explanation: First of all, a muscle is made up of hundreds to thousands of muscle cells (called myocytes) organized into bundles called fascicles. Skeletal muscle cells are long and thin so they are usually referred to as muscle fibers.

Detailed explanation-4: -Skeletal muscles contain connective tissue, blood vessels, and nerves. There are three layers of connective tissue: epimysium, perimysium, and endomysium. Skeletal muscle fibers are organized into groups called fascicles. Blood vessels and nerves enter the connective tissue and branch in the cell.

Detailed explanation-5: -Skeletal muscles 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.
