Skeletal muscles (commonly referred to as muscles) are organs of the vertebrate muscular system and typically are attached by tendons to bones of a skeleton. The muscle cells of skeletal muscles are much longer than in the other types of muscle tissue, and are often known as muscle fibers. The muscle tissue of a skeletal muscle is striated – having a striped appearance due to the arrangement of the sarcomeres. Skeletal muscles are voluntary muscles under the control of the somatic nervous system. The other types of muscle are cardiac muscle which is also striated and smooth muscle which is non-striated; both of these types of muscle tissue are classified as involuntary, or, under the control of the autonomic nervous system.A skeletal muscle contains multiple fascicles – bundles of muscle fibers. Each individual fiber, and each muscle is surrounded by a type of connective tissue layer of fascia. Muscle fibers are formed from the fusion of developmental myoblasts in a process known as myogenesis resulting in long multinucleated cells. In these cells the nuclei termed myonuclei are located along the inside of the cell membrane. Muscle fibers also have multiple mitochondria to meet energy needs. Muscle fibers are in turn composed of myofibrils. The myofibrils are composed of actin and myosin filaments called myofilaments, repeated in units called sarcomeres, which are the basic functional, contractile units of the muscle fiber necessary for muscle contraction. Muscles are predominantly powered by the oxidation of fats and carbohydrates, but anaerobic chemical reactions are also used, particularly by fast twitch fibers. These chemical reactions produce adenosine triphosphate (ATP) molecules that are used to power the movement of the myosin heads.
"Muscles" is a 1982 soul single written and produced by Michael Jackson and performed by American R&B/soul singer Diana Ross. The single reached number ten on the pop singles chart and number four on the R&B singles chart upon its release and was the first single from her gold-certified album, Silk Electric. The song, which was named after Jackson's pet snake and was written for Ross and her "desire" for a muscle-bound lover, also gave Ross her twelfth and latest Grammy nomination for Best Female R&B Vocal Performance. The song was recorded in 1997 by producer/DJ Peter Rauhofer recording as Club 69 and was a featured single on the Club 69 album Style. The vocals on this version of "Muscles" are performed by singer-songwriter, Suzanne Palmer. Lil' Kim sampled "Muscles" for her rap "Diamonds" but it was not included in the final cut of her album The Notorious K.I.M. Young Jeezy also sampled "Muscles" for the title track of his album The Inspiration.

It was pretty incredible and really hard to describe, it almost looked like a load of muscles contracting. It was clear the creature, which Dickinson later discovered was alion's mane jellyfish— the largest species of jellyfish in the world— wasn't dead. It's alive, Dickinson's son confirmed. The family stared at the jellyfish, and sure enough, it continued to move.
It's a whole-body smash fest, it normally takes about a week or 10 days to recover. Your muscles are broken down systemically, and you're hungry consistently for three or four days.
