脊椎动物

In addition, we selected animal species as standard indicators of the state of the environment to map: 1 contamination of vertebrates with 137 Cs in the EZ and 2 beta-activity of mollusc shells indicating 90 Sr, in the whole Dnieper drainage area, in the Kiev Administrative Region, and in the EZ.

而且还选择一些动物物种作为环境状况的标准指示生物，目的是为了阐明1 37Cs在隔离区脊椎动物体内的污染情况；整个第聂伯河流域、基辅行政区和隔离区软体动物贝壳内 90Sr的β活性。

Recent studies indicate that there is a remarkable similarity in early heart development pattern among Drosophila, vertebrate and human.

最近的研究表明，果蝇的早期心脏发育模式与脊椎动物及人的心脏早期发育模式具有惊人的相似性。

Consistent with this, oral teeth are proposed to arise exclusively from ectoderm, contributing to tooth enamel epithelium, and from neural crest derived mesenchyme, contributing to dentin and pulp.

脊椎动物的口腔发育被认为是始于外胚层的内陷，因此牙齿的发育被认为是外胚层和神经嵴来源的间充质。

The part of the ectoderm in a vertebrate embryo that lies on either side of the neural tube and develops into the cranial, spinal, and autonomic ganglia.

神经脊，脊椎动物胚胎外胚层的一部分。位于神经管的两侧，并逐步发展成头颅神经元、脊髓神经元、自主神经系统神经元

Endemism of vertebrates and invertebrates is also very high.

脊椎动物和无脊椎动物的Endemism也非常高。

Most vertebrate hormones originate in specialized tissues (see endocrine system; gland) and are carried to their targets through the circulation.

大多数脊椎动物的激素来自于专门的组织，透过循环带往目的地。

Most vertebrate hormone s originate in specialized tissues (see endocrine system; gland) and are carried to their targets through the circulation.

大多数脊椎动物的激素来自于专门的组织，透过循环带往目的地。

In higher vertebrates, such as mammals and birds, the mesoderm and endoderm are generated from an axis running through the centre of the embryo.

在高等脊椎动物中，中胚和内胚层在胚胎中心的轴部产生。

Bones are rigid organs that form part of the endoskeleton of vertebrates.

骨为坚硬的器官，为脊椎动物内骨骼的一部分。

The internal structure composed of bone and cartilage that protects and supports the soft organs, tissues, and other parts of a vertebrate organism; endoskeleton.
