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.
Describe the events that must occur in the muscle cell before calcium is released from this organelle. 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.4. Dr. Hodges notes that Davidâs exhaled carbon dioxide levels are elevated.aw muscle contraction (masseter spasm) is one of the key physical findings seen in Davidâs case of malignant hyperthermia.
