Sekundaarossifikatsioonikeskused

Sekundaarossifikatsioonikeskused, also known as secondary ossification centers, are regions within a long bone where ossification occurs after the initial formation of the bone. This process is crucial for the growth and development of long bones, particularly during childhood and adolescence. The primary ossification center, or epiphysis, is the first to form, followed by the appearance of secondary ossification centers. These centers are typically located at the metaphysis, the region between the epiphysis and the diaphysis. The secondary ossification centers play a significant role in the bone's ability to withstand mechanical stress and contribute to the bone's overall strength and resilience. The process of secondary ossification is a complex interplay of cellular activities, including osteoblast and osteoclast function, which work together to deposit and resorb bone tissue, respectively. This process is essential for the proper growth and development of long bones and is a critical aspect of skeletal biology.
