What is the function of calcium in the body?

Answer 1

• Calcium is responsible for construction, formation and maintenance of bone and teeth. This function helps reduce the occurrence of osteoporosis.
• Calcium is a vital component in blood clotting systems and also helps in wound healing.
• Calcium helps to control blood pressure, nerve transmission, and release of neurotransmitters.
• Calcium is an essential component in the production of enzymes and hormones that regulate digestion, energy, and fat metabolism.
• Calcium helps to transport ions (electrically charged particles) across the membrane.
• Calcium is essential for muscle contraction.
• Calcium assists in maintaining all cells and connective tissues in the body.
• Calcium may be helpful to reduce the incidence of premature Heart disease, especially if adequate intakes of magnesium are also maintained.
• Calcium may help to prevent periodontal disease (gum disease).

Answer 2

Calcium ions have a wide variety of important functions in the

activity of the nervous system. They control transmitter

release, synaptic plasticity, firing rate, gene expression, and cell

death (see refs. 1 and 2). There is no doubt that calcium ions

entering through the surface membrane have a major function

in many of these processes. In recent years, however, a growing

body of evidence suggests that calcium released from intracellular

stores also may play an important role in calcium control

of neuronal function (3-5). Hence, the study of intracellular

calcium dynamics is significant in this context. An exciting way

to study such dynamics is through the examination of calcium

sparks.

Calcium sparks are sudden localized increases in intracellular

calcium concentration ([Ca21]in). First described in Xenopus

laevis oocytes and named calcium puffs (6), they were later found

in heart muscle (7), skeletal muscle (8), smooth muscle (9), PC12

cells (10), and HeLa cells (11, 12). Calcium sparks seem to be of

great functional significance in processes regulated by calcium in

health and disease (9, 13, 14). The nomenclature (sparks or

puffs), the definition, and the size of calcium sparks vary among

preparations; however, most of the studies point out that they are

a part of intracellular calcium dynamics. Because [Ca21]in is of

great importance in the function of several key processes in the

nervous system, we examined whether such sudden and localized

increases in [Ca21]in also occur in neurons.
