Some people have low levels of calcium circulating in the blood, a condition known as hypocalcemia. While for many this disorder has little to no effect, for some it can be life-threatening. How could low levels of calcium harm an individual?

Question

Quizplus · Accepted Answer

Calcium ions play a crucial role in synaptic transmission, particularly in the release of neurotransmitters from the presynaptic cell. When calcium levels are low, it can lead to a reduction in the number of signals sent between neurons because the release of neurotransmitters is diminished. This can affect muscle contractions, heart rhythm, and various other physiological processes.
