Parathyroid hormone (PTH), also called parathormone or parathyrin, is a hormone secreted by the parathyroid glands that is important in bone remodeling, which is an ongoing process in which bone tissue is alternately resorbed and rebuilt over time. PTH is secreted in response to low blood serum calcium (Ca 2+) levels.

The Legion of Honor was inspired by the French pavilion, a replica of the Palais de la LÃ¨gion dâHonneur in Paris, at San Franciscoâs Panama-Pacific International Exposition of 1915. The museum opened in 1924 in the Beaux Artsâstyle building designed by George Applegarth on a bluff overlooking the Golden Gate Bridge.
