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.
Primary Hyperparathyroidism. Primary hyperparathyroidism is a metabolic disorder in which one (or more) of the parathyroid glands produces too much parathyroid hormone, which can result in the loss of bone tissue. function of the parathyroid hormone is to keep blood calcium levels from going too low by releasing calcium from bones, conserving calcium that would be excreted by the kidneys, and increasing calcium absorption from food. When the hormone overacts, the result is a rise in the blood calcium level.
