When blood calcium levels are low, it means that calcium is not being reabsorbed in the intestine or released from the bones. This could lead to uncontrollable twitching, known as a disorder called tetany, caused by low blood calcium levels.

Cells that free calcium from bone to maintain blood calcium levels are called?
osteoblasts
What happens when blood calcium levels keep on increasing?
The calcium is released from bones and absorbed by the kidneys and the intestines, then the blood calcium level increases.
Low levels of calcium in the blood directly stimulate?
calcitonin
The hormone released in response to low blood calcium levels is?
Calcitonin
Calcitonin causes an increase in blood calcium levels true or false?
False.
Which is greater when blood calcium levels when parathyroid hormone is increased or decreased?
When calcium levels increase, parathyroid hormone decreases. When calcium levels decrease, parathyroid hormone increases. This is known as a negative feedback system.
Under which condition can pastures be responsible for milk fever in dairy cows?
An excess amount of calcium-rich plants like alfalfa can cause milk fever because blood calcium levels can be quickly decreased enough that the cow is unable to draw calcium from her bones to make up for the decreased levels, causing her to go into depression due to very low blood calcium levels.
What is the medical term meaning decreased parathyroid activity?
Hypoparathyroidism is the medical term for decreased parathyroid activity, leading to low levels of parathyroid hormone and calcium in the blood, which can result in symptoms like muscle cramps, tingling sensations, and seizures. Treatment often involves calcium and vitamin D supplementation.
Does parathormone increase or decrease calcium levels in the blood?
It increases the concentration of calcium in the blood. Calcitonin decreases blood calcium levels.
Where is excess calcium stored when blood calcium levels increase?
Blood
Which gland relates to the structure of calcium in blood?
The thyroid gland produces calcitonin which lowers blood calcium levels and the parathyroids produce parathyroid hormone which increases blood calcium levels.
Can decreased calcium in the blood cause muscle spasms?
Yes, when severe.
What gland has functions in the parathyroid hormone to regulate calcium levels in the blood and tissues?
The parathyroid glands produce and secrete parathyroid hormone which regulates calcium levels in the blood. Since it increases blood calcium levels, it promotes the function of osteoclasts, which reduce the calcium in bones and promote its increase in the blood stream.
What is the hormone whose production in inadequate amounts results in tetany?
excess calcitonin or decreased parathormone
Will a lack of calcium effect other parts of your body apart from brittle bones?
Because bone stores of calcium can be used to maintain adequate blood calcium levels, short-term dietary deficiency of calcium generally does not result in significantly low blood calcium levels. But, over the long term, dietary deficiency eventually depletes bone stores, rendering the bones weak and prone to fracture. A low blood calcium level is more often the result of a disturbance in the body's calcium regulating mechanisms, such as insufficient PTH or vitamin D, rather than dietary deficiency. When calcium levels fall too low, nerve and muscle impairments can result. Skeletal muscles can spasm and the heart can beat abnormally-it can even cease functioning.
Does calcitonin cause a decrease in blood calcium ion levels?
The hormone Calcitonin has the effect of reducing blood calcium levels. The hormone comes from the thyroid gland and works in basically three ways. 1. It works to slow absorption of calcium by the intestine. 2. It also inhibits the osteoclast (cells in bone that break down old bone tissue) that raise blood calcium levels. 3. It causes osteoblast (cells in bone that lay down new bone matrix) to form new bone. This explanation is at it's simplest form of course.
Which hormonal imbalances cause diabetes insipidus?
decreased Insulin level will result in increased levels of blood glucose or in other terms diabetes mellitus
