Some people have low levels of calcium circulating in the blood, a condition known as hypocalcemia. while for many this disorder
kap26 [50]

Answer:

low level of calcium would result in fewer signals sent between pre and post synaptic cells.

Explanation:

The calcium has a main role in signal transmission mechanism and here is the mechanism :

1-the impulse reaches the synapse (depolarization which is a voltage change).

2-the voltage gated calcium channels open and let calcium flow into the cell.

3-the calcium causes the synaptic vesicles to rupture and release chemical transmitters which cross the synaptic cleft and finally bind to receptors on the post synaptic cell (transmitting the signal)

so it's obvious that if calcium concentration decreases, the signal transmission also decreases.
