Essay About Muscle Contraction Process

Process of muscle contraction The process of muscle contraction involves a series of biochemical reactions in the body of a living organism. The order of events leading to contraction is initiated in the central nervous system, as either voluntary activity from the brain or as reflex activity from the spinal cord.

Essay About Muscle Contraction Process

The whole process is called the mechanism of muscle contraction and it can be summarized in three steps: (1) A message travels from the nervous system to the muscular system, triggering chemical reactions. (2) The chemical reactions lead to the muscle fibers reorganizing themselves in a way that shortens the muscle--that’s the contraction.

Essay About Muscle Contraction Process

The process of muscle contraction begins when the action potential travels along the sarcolemma and down the T tubules. Upon reaching the T tubules the action potential causes the terminal cisternae of the sarcoplasmic reticulum (SR) to release calcium into the sarcoplasm, where it becomes available to the myofilaments.

Essay About Muscle Contraction Process

Muscle contraction is when a tension is made from an action potential to cause a movement in of the muscle, this requires interactions between actin filaments and myosin. The Skeletal muscles contract in a sliding filament model: Firstly an action potential that comes from the CNS reaches an alpha motor neuron.

Essay About Muscle Contraction Process

Muscle contraction is a complex series of chemical changes inside the muscle cell. For a muscle to contract, the muscle fiber is stimulated and calcium ions are released. The calcium ions move to the middle of the sarcomere. The sarcomere is the microscopic area in the middle of the muscle fiber, which is made of actin and myosin.

The sequence of events that converts action potentials in a muscle fiber to a contraction is know as excitation contraction coupling. In order for a skeletal muscle fiber to contract, it has to get a signal from the nervous system. The part of the nervous system that it gets a signal from is called a motor neuron.
