Most of our skeletal muscles are attached to bone on either end by tendons. As the muscles contract‚ they exert force on the bones. This force helps to support and move our body. Normally one end of the muscle is fixed in its position and the other end moves during contraction. The Origin is the attachment site that is stationary during contraction. The insertion is the site that does move when a muscle contracts. When we discuss the position of the Origin and insertion points‚ the insertion

Discuss the relationship between distribution of muscle fibre type and performance. How might exercise training modify or change a person’s fibre-type distribution? There are four different types of muscle fibres: type 1‚ type 2a‚ type 2x‚ and type 2c. “A single skeletal muscle contains fibres having different speeds of shortening and ability to generate maximal force: type 1 (slow-twitch) fibres and type 2 (fast-twitch) fibres. Type 1 fies take approximately 110 ms to reach peak tension when

Human Muscular System Visceral muscle is found inside of organs like the stomach‚ intestines‚ and blood vessels. The weakest of all muscle tissues‚ visceral muscle makes organs contract to move substances through the organ. Because visceral muscle is controlled by the unconscious part of the brain‚ it is known as involuntary muscle—it cannot be directly controlled by the conscious mind.

650 muscles that allow the body to move in different ways and also helps with blood flow. There are three types of muscles including: visceral‚ skeletal‚ and cardiac.
