The activation of physiologically inactive medullary bone osteoclasts by parathyroid hormone (PTH) was examined using light and electron microscopy and histomorphometric methods. Medullary bone osteoclasts are functionally inactive during the avian egg-laying cycle when an egg shell is not being cal...
