Patient/caregiver was instructed upon calcitriol and mechanism of action as follows: Low levels of serum calcium in the body stimulate increased synthesis of parathyroid hormone by the parathyroid glands. Parathyroid hormone and low levels of serum calcium and phosphorus in the body also stimulate synthesis of calcitriol by the kidneys. Calcitriol is the final natural active form of vitamin D, which is synthesized from precursors/prior forms synthesized in the skin and liver. This precursor form [...]

Patient/caregiver was instructed upon the role of parathyroid hormone in serum calcium regulation as follows: Parathyroid hormone is produced by four parathyroid glands, located behind the thyroid gland in the neck. Low levels of serum calcium in the body stimulate increased synthesis of parathyroid hormone by the parathyroid glands. Increased parathyroid hormone secretion results in resorption of the bone and consequently, leads to mobilization of calcium and phosphorus from the bone into the blood, thus helping [...]

Patient/caregiver was instructed upon regulation of serum calcium as follows: The serum calcium levels are regulated primarily by two hormones, parathyroid hormone and calcitonin. Also, vitamin D3 or calcitriol, contributes significantly to the regulation of the serum calcium levels. Low levels of serum calcium in the body stimulate increased synthesis of parathyroid hormone by the parathyroid glands. Increased parathyroid hormone secretion results in resorption of the bone and consequently, leads to mobilization of calcium and phosphorus [...]

Patient/caregiver was instructed upon role of calcium in various biological functions as follows: Calcium is one of the most important minerals found in the human body. Calcium forms an important component of the skeletal structures and plays a significant role in the normal function of various vital body parts, as discussed below. Hormone release Hormones, such as, insulin and growth hormone, are synthesized in the cells of pancreas and pituitary gland and play an important [...]

Calcium forms an important component of the skeletal structures and plays a significant role in the normal function of various vital body parts, as discussed below. Skeletal muscle Contraction Transmission of nerve impulse to the skeletal muscle plays an important role with initiating muscle contraction. Calcium plays a significant role [...]
