一、甲状旁腺功能减退(甲旁减)时,磷钙代谢障碍有哪些表现? 甲状旁腺主要的生理功能是调节体内钙代谢,促使血浆钙维持于一很窄的正常范围,并维持体内钙磷平衡。当甲状旁腺素分泌不足或失去活性时,导致细胞外液钙浓度降低,破坏神经-肌肉膜电位稳定性,以致周围及中枢神经系统的应激性、兴奋性增高。临 First, the hypoparathyroidism (hypoparathyroidism), phosphorus metabolism disorders which performance? The main physiological function of the parathyroid gland is to regulate calcium metabolism, and promote plasma calcium in a very narrow range of normal and maintain the body Calcium and phosphorus balance. When parathyroid hormone secretion or loss of activity, resulting in decreased extracellular calcium concentration, disruption of neuromuscular membrane potential stability, resulting in peripheral and central nervous system stress, increased excitability.
