Growth hormone is the most important stimulus for epiphyseal plate activity during infancy and childhood. It stimulates chondrocyte division in the epiphyseal plates, leading to bone growth. Thyroid hormone and calcium play important roles in bone development and maintenance, but they are not the primary signals for epiphyseal plate activity. Parathyroid hormone regulates calcium levels in the blood but does not directly stimulate bone growth.
