What is it called when an uncontrollable muscle spasm due to overactive neurons caused by lack of calcium?
This condition is called tetany, which is characterized by involuntary muscle contractions caused by decreased levels of calcium in the blood. It can result in symptoms such as muscle twitching, cramps, and spasms.
What word is used to describe sustained muscle spasms due to hypocalcemia?
The word used to describe sustained muscle spasms due to hypocalcemia is "tetany." This condition occurs when there is a deficiency of calcium in the blood, leading to increased excitability of nerve and muscle cells. Tetany is characterized by muscle cramps, spasms, and twitching, particularly in the hands and feet.
What is done by calcium channel blockers?
Calcium channel blockers block the entry of calcium into muscle cells in artery walls. Muscle cells need calcium to constrict, so reducing their calcium keeps them more relaxed and lowers blood pressure.
What happens with calcium in alkalosis?
In alkalosis, the elevated pH levels in the blood can lead to decreased ionized calcium levels. This occurs because alkalosis increases the binding of calcium to proteins, particularly albumin, resulting in less free calcium available in the bloodstream. Consequently, symptoms such as muscle spasms or tetany may arise due to the lower levels of ionized calcium, which is critical for proper neuromuscular function.
What is calcium channel blockers?
A calcium channel blocker is a drug that lowers blood pressure by either preventing calcium from entering cells of the cardiac muscle, or the smooth muscle cells of the blood vessel walls.
What is the medical term meaning a condition of painful muscle cramps resulting from a low amount of calcium in the blood?
The medical term for this condition is hypocalcemia. It occurs when there is a low level of calcium in the blood, leading to symptoms like muscle cramps and spasms due to inadequate calcium for muscle function. Treatment may involve calcium supplementation or addressing the underlying cause of the low calcium levels.
How decreased blood supply effect muscle activity?
Decreased blood supply in the muscle can cause anoxia then paralysis.
What is the hormone whose production in inadequate amounts results in tetany?
excess calcitonin or decreased parathormone
What are the key differences between tetany and tetanus, and how can they be distinguished from each other?
Tetany is a condition characterized by involuntary muscle contractions due to low levels of calcium in the blood, while tetanus is a bacterial infection that causes severe muscle stiffness and spasms. Tetany is typically caused by low calcium levels, while tetanus is caused by the bacteria Clostridium tetani. Tetany can be distinguished from tetanus by the presence of muscle twitching and spasms in tetany, while tetanus is characterized by more severe muscle stiffness and spasms.
What diagnostic term for a condition of painful muscle cramps resulting from a low amount of calcium in the blood is?
The diagnostic term for a condition characterized by painful muscle cramps due to low levels of calcium in the blood is "hypocalcemia." This condition can lead to increased neuromuscular excitability, resulting in symptoms such as muscle cramps and spasms. Treatment often involves addressing the underlying cause of the hypocalcemia and may include calcium supplementation.
Decreased blood calcium levels would result in?
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.
Which is greater when blood calcium pth hormone is increased or decreased?
When parathyroid hormone (PTH) is increased, blood calcium levels typically rise because PTH stimulates the release of calcium from bones, increases calcium reabsorption in the kidneys, and promotes the activation of vitamin D, which enhances intestinal absorption of calcium. Conversely, when PTH levels are decreased, blood calcium levels tend to drop. Therefore, increased PTH leads to greater blood calcium levels, while decreased PTH results in lower blood calcium levels.
