it occurs when the PARATHYROID HOROMONE (PTH) falls to low.
Tetanus (Clostrudium tetani toxin) gets its name from its ability to cause tetany. The most common cause is low serum calcium levels which can be caused by parathyroid hormon…e or vitamin D deficiency. Hyperventilating or other acid-base problems can shift the binding of calcium and cause effectively low levels and tetany. Low magnesium and excess potassium can also do it.
Hypo = too low Secretion = production Hyposecretion = too low production Too low production of insulin causes hyperglycemia. The chronic condition is called Diabetes Mel…litus.
excess calcitonin or decreased parathormone
Hypocalcemia ( a low serum calcium level), not hypercalcemia ( a high serum calcium level), tends to cause muscle spasm and in severe cases may lead to muscle tetany.

Clostridium tetani. This is a bacterium which commonly lives in the soil. It can only grow and produce toxins when little oxygen is around, so just playing around in the dirt …would not get you infected. Typically, tetanus occurs when a deep stabwound is made with a dirty object, say a rusty nail, on which the Clostridium bacteria are present. On superficial wounds, there would be too much oxygen and the bacteria wouldn't grow, in a deep wound that is more or less shut off from the outside air, oxygen is quickly consumed by other bacteria, allowing the Clostridia to reproduce and produce toxins. These are responsible for the cramps typical for tetanus.
