Muscle

Muscle is a soft tissue found in most animals. Muscle cells contain protein filaments of actin and myosin that slide past one another, producing a contraction that changes both the length and the shape of the cell. Muscles function to produce force and motion. They are primarily responsible for maintaining and changing posture, locomotion, as well as movement of internal organs, such as the contraction of the heart and the movement of food through the digestive system via peristalsis.

Muscle tissues are derived from the mesodermal layer of embryonic germ cells in a process known as myogenesis. There are three types of muscle, skeletal or striated, cardiac, and smooth. Muscle action can be classified as being either voluntary or involuntary. Cardiac and smooth muscles contract without conscious thought and are termed involuntary, whereas the skeletal muscles contract upon command. Skeletal muscles in turn can be divided into fast and slow twitch fibers.

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 (song)

"Muscles" is a 1982 hit single written and produced by Michael Jackson, and performed by American singer Diana Ross. It was the first single release from Diana's Gold-certified album Silk Electric.

The single reached number #7 in Cash Box magazine and #10 on the Billboard Hot 100 chart. It climbed as high as #4 on the Billboard Soul chart. The kinky song, which was supposedly named after Jackson's pet snake, was written for Miss Ross and her "desire" for a muscle-bound lover. It earned the superstar diva a twelfth and latest Grammy Award nomination for Best Female R&B Vocal Performance. (Although Diana never won a competitive Grammy, she was awarded an honorary Lifetime Achievement Award from NARAS in 2012.)

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.
