The functionally first of all considerable components of the carotid bodies are glomus cells and nerve fibres. The glomus cells form two groups. The chemoreceptor cells belong in one of these, the capsular cells in the other. The chemoreceptor cells are polygonal bodies. in their cytoplasm, organella are expressed. The cell nucleus is round, chromatin is homogeneous. Cells are characterized by the osmiophilic bodies. The capsular cells are long-shaped bodies with processes, they are associated with the chemoreceptor cells and sometimes lap over these, like veils. A number of the nerve fibres take place in Schwann's cells wrapped in a mesaxon membrane. The larger part, surrounds the round cell-nests consisting of chemoreceptor cells with a close-meshed network. From the network some fibres draw to the chemoreceptor cells and terminate on these in the form of boutons. Nerve endings form synapses with the chemoreceptor cells. Three forms of these have been found. One of these is the conventional synapsis, the other the saccular synapsis and the third one the parallel contact. Conventional synapses contain all the components identified in the neurons of the central nervous system. Saccular synapses are the magnified pictures of boutons. They consist of axolemma, axoplasm, synaptic vesicles, and mitochondria. In the parallel contacts, the axolemma and cytolemma touch each other. In the axoplasm, there are synaptic vesicles and mitochondria. Conventional synapses conduct peripherally, saccular synapses and parallel contacts centrally. On chemoreceptor cells, there are no neuronal marks, consequently, they are no interneurons. For reciprocal synapses the morphological bases are missing. The chemoreceptor cells are sensory cells.
颈动脉体功能上首先重要的组成部分是球细胞和神经纤维。球细胞形成两组。化学感受细胞属于其中一组，被膜细胞属于另一组。化学感受细胞是多角形的，其细胞质中有细胞器表达。细胞核呈圆形，染色质均匀。细胞以嗜锇小体为特征。被膜细胞是有突起的长形细胞，它们与化学感受细胞相关联，有时像面纱一样覆盖在这些细胞上。许多神经纤维位于包裹在髓鞘膜中的施万细胞内。较大部分围绕着由化学感受细胞组成的圆形细胞巢，形成一个紧密的网络。从这个网络中，一些纤维延伸到化学感受细胞，并以终扣的形式终止于这些细胞上。神经末梢与化学感受细胞形成突触。已发现这些突触有三种形式。一种是传统突触，另一种是囊状突触，第三种是平行接触。传统突触包含中枢神经系统神经元中鉴定出的所有成分。囊状突触是终扣的放大图像。它们由轴膜、轴质、突触小泡和线粒体组成。在平行接触中，轴膜和细胞膜相互接触。在轴质中，有突触小泡和线粒体。传统突触向周围传导，囊状突触和平行接触向中枢传导。在化学感受细胞上，没有神经元标记，因此它们不是中间神经元。相互突触的形态学基础也不存在。化学感受细胞是感觉细胞。
