Skeletal fluorosis. Skeletal fluorosis. Fluorosis patient in the industrial city of Raigarh, India. Specialty. Rheumatology. Skeletal fluorosis is a bone disease caused by excessive accumulation of fluoride leading to weakened bones. [ 1] In advanced cases, skeletal fluorosis causes painful damage to bones and joints .
Calcium is a chemical element; it has symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth's crust, and ...
Calcium metabolism is the movement and regulation of calcium ions (Ca 2+) in (via the gut) and out (via the gut and kidneys) of the body, and between body compartments: the blood plasma, the extracellular and intracellular fluids, and bone. Bone acts as a calcium storage center for deposits and withdrawals as needed by the blood via continual ...
Calcium in biology. Calcium is used in many nerves in the voltage-gated calcium channel which is slightly slower than the voltage-gated potassium channel. It is most notably used in the cardiac action potential. [1] Calcium ions (Ca 2+) contribute to the physiology and biochemistry of organisms' cells. They play an important role in signal ...
Even if small amounts are ingested over long periods of time, the prolonged high levels of calcium ions have large negative effects on the animals. [30] The issues these animals experience are muscle weakness, and calcification of blood vessels, heart valves, liver, kidneys, and other soft tissues, which eventually can lead to death.
Hypocalcemia is a medical condition characterized by low calcium levels in the blood serum. [5] The normal range of blood calcium is typically between 2.1–2.6 mmol/L (8.8–10.7 mg/dL, 4.3–5.2 mEq/L), while levels less than 2.1 mmol/L are defined as hypocalcemic.
Electrolyte imbalance. Diagram of ion concentrations and charge across a semi-permeable cellular membrane. Electrolyte imbalance, or water-electrolyte imbalance, is an abnormality in the concentration of electrolytes in the body. Electrolytes play a vital role in maintaining homeostasis in the body. They help to regulate heart and neurological ...
Dental fluorosis is a common [ 2] disorder, characterized by hypomineralization of tooth enamel caused by ingestion of excessive fluoride during enamel formation. [ 3] It appears as a range of visual changes in enamel [ 4] causing degrees of intrinsic tooth discoloration, and, in some cases, physical damage to the teeth.
