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.
The parathyroid hormone (PTH) causes increases in the serum calcium levels (through acting in the gut, kidneys, bone and Vit.D) and the calcitonin hormone antagonizes the action of PTH. Excess of PTH causes hyperparathyroidism, and the deficit causes hypoparathyroidism.he parathyroid hormone (PTH) causes increases in the serum calcium levels (through acting in the gut, kidneys, bone and Vit.D) and the calcitonin hormone antagonizes the action of PTH.
