摘要
本文对19例人胚胎软骨进行了微血管造影观察。自第2~3胎月以后,各部位软骨内相继出现血管,但它是以一种特殊的方式,即软骨管的形式存在于软骨内。软骨管的形成方式,包括两个方面:1.随着软骨的增大,原来处于软骨表浅部位的软骨管,被逐渐包埋于软骨内;2.软骨管本身不断增长、分支,并向软骨深部推进。软骨管的功能除滋养软骨外,它们还是软骨生长中心,并且直接参与骺二次化骨中心的成骨活动。
Cartilages of 19 human fetuses were studied by microangiographic and histological methods.Blood vessels were enclosed in a special structure,the cartilage canal which were present in individual cartilages from 2~3 months of the fetus.The cartilage canals developed either from the superficial blood vessels which was gradually embedded in the cartilage as it grew,or blood vessels in the cartilage canal grew and divided themselve progressively and penetrated into the deeper part of the cartilage.In addition to the nutritional supply for the centers of the growth of cartilage,the cartilage canal participates directly in the osteogenesis of the secondary centers of ossification.
