muscle

     

Muscle (from Latin musculus, iminutive of mus "mouse") is contractile tissue of the body and is derived from the mesodermal layer of embryonic germ cells. Muscle cells contain contractile filaments that move past each other and change the size of the cell. They are classified as skeletal, cardiac, or smooth muscles. Their function is to produce force and cause motion. Muscles can cause either locomotion of the organism itself or movement of internal organs. Cardiac and smooth muscle contraction occurs without conscious thought and is necessary for survival. Examples are the contraction of the heart and peristalsis which pushes food through the digestive system. Voluntary contraction of the skeletal muscles is used to move the body and can be finely controlled. Examples are movements of the eye, or gross movements like the quadriceps muscle of the thigh. There are two broad types of voluntary muscle fibers: slow twitch and fast twitch. Slow twitch fibers contract for long periods of time but with little force while fast twitch fibers contract quickly and powerfully but fatigue very rapidly.

Trivia about muscle

  • It's any tissue that contracts & relaxes, causing movement of the limbs & other body parts
  • A flexor is one of these that contracts to bend a part of the body
  • The sartorius, which flexes the thigh, is the body's longest one of these
  • The stapedius, the smallest of these, controls the stapes, the smallest bone
  • C:The levator scapulae, for example; it helps raise the shoulder blade
  • The stapedius in the middle ear is one of these that moves the stapes
  • In 1996 (seems late) researchers announced a new one of these body parts, the spheno-mandibularis
  • In 1996 Gary Hack discovered the sphenomandibularis, a previously unknown one of these in the face
  • Very simply, myalgia is pain in any one of these, often due to a stress injury
  • It's healthy to keep down your body fat, but not to the point of the Growleywogs, who are all bone, skin & this
