[Answer] What ion stimulates the contraction of muscle?

Answer: calcium
What ion stimulates the contraction of muscle?

In vertebrate animals there are three types of muscle tissues: skeletal smooth and cardiac. Skeletal muscle constitutes the majority of muscle mass in the body and is responsible for locomotor activity. Smooth muscle forms blood vessels gastrointestinal tract and other areas in the body that produce sustained contractions. Cardiac muscle make up the heart which pumps blood. Skeletal and cardiac muscles are called striated musclebecause of their striped appearance under a microscope which is du…

Myocardial contractility represents the innate ability of the heart muscle to contract. The ability to produce changes in force during contraction result from incremental degrees of binding between different types of tissue that is between filaments of myosin and actin tissue. The degree of binding depends upon the concentration of calcium ions in the cell. Within an in vivo intact heart the action/response of the …

Stimulation. The stimulation for these contractions likely originates in modified smooth muscle cells called interstitial cells of Cajal. These cells cause spontaneous cycles of slow wave potentials that can cause action potentials in smooth muscle cells. They are associated with the contractile smooth muscle via gap junctions.

It allows the motor neuron to transmit a signal to the muscle fiber causing muscle contraction .. Muscles require innervation to function—and even just to maintain muscle tone avoiding atrophy.In the neuromuscular system nerves from the central nervous system and the peripheral nervous system are linked and work together with muscles . Synaptic transmission at the neuromuscular junction …

Fused tetanus is when there is no relaxation of the muscle fibers between stimuli and it occurs during a high r…
