Calcitriol zorgt op zijn beurt voor de absorptie van calcium uit de darmen en de mobilisatie van calciumionen uit been. <a href="/wiki/Calcitonine" title="Calcitonine">Calcitonine</a> is een hormoon dat geproduceerd wordt door de medullaire schildkliercellen en dat het serumcalcium verlaagt. Ook de celorganellen zijn belangrijke opslagplaatsen van calcium. Zij accumuleren voortdurend Ca<sup>2+</sup>-ionen en laten deze los tijdens bepaalde cellulaire acties. Voorbeelden van zulke organellen zijn de <a href="/wiki/Mitochondri%C3%ABn" class="mw-redirect" title="Mitochondriën">mitochondriën</a> en het <a href="/wiki/Endoplasmatisch_reticulum" title="Endoplasmatisch reticulum">endoplasmatisch reticulum</a>. </p> <div class="mw-heading mw-heading3"><h3 id="Klinisch_belang_van_calcium">Klinisch belang van calcium</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Calcium&veaction=edit&section=6" title="Bewerk dit kopje: Klinisch belang van calcium" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Calcium&action=edit&section=6" title="De broncode bewerken van de sectie: Klinisch belang van calcium"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Een te hoog serumcalciumgehalte heet <a href="/wiki/Hypercalci%C3%ABmie" title="Hypercalciëmie">hypercalciëmie</a>. Klachten zijn nierstenen, dorst en veel drinken, veel plassen en verwardheid tot psychose aan toe. Hypercalciëmie is een symptoom van te snel werkende bijschildkliertjes. Dit zijn vier orgaantjes, een paar millimeter groot; een klein goedaardig gezwel een van deze kan hypercalciëmie en botontkalking veroorzaken. Hypercalciëmie kan ook veroorzaakt worden door botmetastasen, als de botten aangedaan zijn door uitgezaaide kanker. Een te laag serumcalcium heet <a href="/wiki/Hypocalci%C3%ABmie" title="Hypocalciëmie">hypocalciëmie</a> en kan krampen in de vingers veroorzaken en wordt bijvoorbeeld gezien bij hyperventilatie, waarbij door de snelle ademhaling het koolzuurgehalte van het bloed daalt en daardoor de pH stijgt. Ook wordt dit gezien als bij een schildklieroperatie per ongeluk de vier bijschildklieren zijn verwijderd. Calcium speelt een rol bij het omzetten van een elektrische prikkel in een chemische; met andere woorden het is nodig om de zenuwcel en de spiercel te laten reageren op een actiepotentiaal. Calciumantagonisten of calcium-instroombeperkende middelen kunnen gebruikt worden om de hartslag te vertragen, de bloeddruk te verlagen, de zuurstofbehoefte van het hart te verminderen. Sommige worden voorgeschreven bij duizeligheid of migraine.
