Certain types of muscle cells are activated by calcium ions. After activation, the cells expend energy putting the calcium ions back outside the cell. After death, the membranes become more permeable to calcium and the cells don't expend as much energy to push the ions out, so the muscles contract. This does lead to rigor mortis and can lead to ejaculation. It's real. It happens.
Immediately after death, the muscles of the body contract in the same manner as they do when the person is alive. Muscle is formed of bundles of long and narrow cells that can span the entire muscleâs length. In the resting state, these cells build up the electric potential across their membrane by actively pumping out calcium ions. Upon receiving a signal from a neuron, the muscle cells open the calcium channels in their cell membrane, and the calcium ions rush in due to the voltage difference between the inside and outside of the cell. These ions then interact with actin and myosin filaments to cause muscle contraction.
