Osteogenesis and growth of the nasal ventral conchae of the piglet.
The present study investigated the osteogenesis and growth of the nasal ventral conchae of piglets aged from 1 to 28 days. Serial transverse sections of paraffin wax-embedded noses were stained and examined by light microscopy. Bone formation occurred in a rostrocaudal direction in the ventral scroll, dorsal scroll, connecting zone, transverse lamina and articular lamina, successively, and occurred by two ossification processes: endochondral ossification and intramembranous bone apposition. Endochondral ossification was responsible for the longitudinally, rostrally directed growth. Rapid transverse bone growth and modelling were centrifugally directed and occurred by intramembranous bone apposition at the eccentric side of the scrolls and resorption at the concentric scroll side. Elongation of the distal scroll extremities took place by intramembranous bone apposition.
