A femoral hernia occurs when the intestine enters the canal carrying the femoral artery into the upper thigh. Femoral hernias are most common in women, especially those who are pregnant or obese. In an umbilical hernia, part of the small intestine passes through the abdominal wall near the navel.
Parathyroid hormone is the most important endocrine regulator of calcium and phosphorus concentration in extracellular fluid. This hormone is secreted from cells of the parathyroid glands and finds its major target cells in bone and kidney.
Parathyroid hormone (PTH) levels in the blood may be analyzed to determine the presence of hyperparathyroidism and its possible role in abnormal calcium levels. Parathyroid hormone influences the levels of both calcium and phosphorus in the body.A portion of PTH is split into 3 fragments in the parathyroid gland before systemic release. The 3 fragments are an amino or N-terminal fragment, a midregion fragment, and a carboxy or C-terminal fragment.he release of PTH is normally stimulated by low calcium levels in the body. PTH release results in a signal to the bones to release calcium into the bloodstream and also to the kidneys to resorb calcium in the collecting system and excrete phosphorus.
