背景情况:
- 在训练期间,在年轻的纯血统赛马中,对第三指甲骨 (MC3) 中间腹膜尺寸的放射测量与腿部疼痛有关.
- 这些MC3形态的发育起源 (先天性与发育性) 仍然不清楚.
研究的目的:
- 量化评估MC3骨尺寸的变化,在整个成长期的纯种小羊.
- 为MC3发展建立规范性数据.
主要方法:
- 一项纵向研究涉及从出生到14个月的20只纯血统小的X光成像.
- 测量了四个线性MC3参数:近距离距离的长度,腹膜中间的背和手掌皮层厚度,背手掌骨髓宽度.

01:09Changes in the Appendicular Skeleton with Age
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...

01:24Bone Formation by Endochondral Ossification
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...
