Sarcoplasmic reticulum

This organelle within the muscle fiber (cell) stores calcium ions until needed for contraction:

Diaphragm

The origin of this muscle includes the xiphoid process; insertion is the central tendon. Contraction of this muscle leads to increased vertical dimension of thoracic cavity which in turn leads to INSPIRATION (inhalation)
