Why is Calcium Ion Concentration Important in Histology?
Calcium ions play essential roles in numerous cellular processes. They act as second messengers in signal transduction pathways, influence muscle contraction in myocytes, and are involved in the secretion of hormones and neurotransmitters. In bone tissue, calcium is a major component of hydroxyapatite, which provides structural rigidity. Abnormal calcium levels can lead to various pathological conditions such as osteoporosis, hypercalcemia, and hypocalcemia.
