Detailed explanation-1: -Skeletal muscles are made up of long and cylindrical cells. They are multinucleate (having many nuclei) and unbranched. They are also known as striated muscles because they have alternate dark and light bands. They move as per our will, hence they are categorised as voluntary muscles.
Detailed explanation-2: -Each skeletal muscle fiber is a single cylindrical muscle cell. 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.
Detailed explanation-3: -These are cylindrical in shape hence can be easily arranged into parallel arrays which increases the strength of the muscles.
