Quick Answer. Calcium is a crucial part of muscle contraction. The ionic element is released from muscles during contraction and relaxation. The release of calcium helps propagate the muscle contraction and relaxation stages. Continue Reading.
The action potential travels down T-tubules 6. Calcium ions are released into the sarcoplasm 3. Jaw muscle contraction (masseter spasm) is one of the key physical findings seen in Davidâs case of malignant hyperthermia. Explain how calcium functions to cause contraction of a skeletal muscle cell.
