âOil-canningâ can be defined as a perceived waviness in the flat areas of roofing and siding panels. Generally the period and amplitude of the wave depend on the continuous width of the flat. Oil-canning is an inherent part of light-gauge cold-formed metal products, particularly those with broad flat areas.
There are three types of muscle tissues: skeletal, cardiac and smooth muscles. a. skeletal muscle: multinucleated, striated; attached to bones producing locomotion, general support and posture; producing heat. Contraction is voluntary, and not long-sustained.
Interactions of Skeletal Muscles in the Body. 1  Prime mover. The muscle that has the major responsibility for causing a particular movement is called the prime mover. 2  Antagonists. Muscles that oppose or reverse a movement are antagonists; when a prime mover is active, its antagonist is stretched and relaxed. 3  Synergists.
