概括
青少年部发育显示,骨和骨的二次骨化中心 (SOC) 影响着骨覆盖. 阴茎骨化不会影响前部覆盖,突出显示SOCs.
科学领域:
- 整形外科的研究研究.
- 儿科骨发育的情况
- 部的生物力学
背景情况:
- 儿科部的骨发育受三状软骨 (TRC) 和阴骨,阴骨和阴骨的二次骨化中心 (SOC) 的影响.
- 这些SOC表现出明显的出现和融合时间,具有性别特异的形态变异.
- 了解SOCs的作用对于分析青少年时期的acetabular覆盖面,版本,倾斜和表面积至关重要.
研究的目的:
- 量化二次骨化中心 (SOCs) 在青春期对骨覆盖面,版本,倾斜和表面积的影响.
- 为了分析骨成熟期间的体形态的性别特异性差异.
主要方法:
- 从540个正常部 (8-19岁) 的CT扫描中生成3D表面重建.
- 使用经过验证的算法提取的acetabular参数 (覆盖面,版本,倾斜,表面积).
- 通过近接大腿骨成熟度指数 (PFMI) 评估骨成熟度,并使用通用线性混合模型分析SOC贡献.
主要成果:
- 骨骨化与增加的上部覆盖率相关 (p < 0.001),骨骨化与增加的后部覆盖率相关 (p < 0.001).
- 上部覆盖与横向倾斜有很强的相关性 (r s = 0.837),后部覆盖与前向倾斜 (r s = 0.788).
- 雌性表现出较大的acetabular前转和横向倾斜,而雄性则具有较大的acetabular表面积. 阴茎骨化没有显著影响前部覆盖.
结论:
- 骨和骨骨化分别是青春期上部和后部骨覆盖的关键驱动因素.
- 阴茎骨化似乎不会影响这个年龄组的前骨覆盖.
- SOCs的发育时间与骨形态变化密切相关,这强调了它们在部稳定性中的作用.

Changes in the Appendicular Skeleton with Age
3.4K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Bone Formation by Endochondral Ossification
8.5K
Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...

Bone Formation by Intramembranous Ossification
10.2K
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...

Growth of Cartilage and Bone Tissue
4.0K
Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...

Development of the Limb Synovial Joints
2.2K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

Bone Remodeling
40.3K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
