Morphological correlations of functional regulation of oxygen consumption have been investigated in single of isolated crustacean stretch receptor neuron. The increase in oxygen consumption is promoted by: 1) redistribution of mitochondria and increase in cytochrome oxidase (CO) activity in mitochondria near to the plasmatic membrane; 2) coordination of mitochondria aggregation rhythms with pO2 rhythms in external environment of a cell; 3) reduction of the area with high CO and mitochondria activity, and reduction of the way of oxygen diffusion; 4) increase in CO activity gradient from periphery to the center of the neuron body; 5) carry of oxygen by water current under hydration of the neuron body, and cytoplasm dilution under transition of a part of gel in sol; 6) cyclic changes in the neuron body and hillock sizes ratio determining carry of oxygen by water current into the neuron body, oxygen absorption by mitochondria in the neuron body, and transition of the water released from oxygen from the neuron body into hillock and further into the external environment.
在单个分离的甲壳类牵张感受器神经元中，已经研究了氧消耗功能调节的形态学相关性。氧消耗的增加由以下因素促进：1）线粒体重新分布以及靠近质膜的线粒体中细胞色素氧化酶（CO）活性增加；2）线粒体聚集节律与细胞外部环境中pO2节律的协调；3）高CO和线粒体活性区域面积的减小以及氧扩散途径的缩短；4）从神经元体周边到中心的CO活性梯度增加；5）在神经元体水合作用下通过水流携带氧气，以及在一部分凝胶转变为溶胶时细胞质稀释；6）神经元体与小丘大小比例的周期性变化，决定了通过水流将氧气携带到神经元体中，神经元体中线粒体对氧气的吸收，以及从氧气中释放的水从神经元体转移到小丘并进一步进入外部环境。
