Final answer:
Pre-osteoclasts develop from myeloid stem cells in the bone marrow, which differentiate into monocytes before becoming osteoclasts.
Step-by-step explanation:
Pre-osteoclasts develop from myeloid stem cells found in the bone marrow. These stem cells give rise to various formed elements, including cells of the myeloblast lineage, which further differentiate into monocytes and eventually into osteoclasts. Osteoclasts are specialized cells that are responsible for the resorption of bone, playing a critical role in bone remodeling and healing processes.
