章鱼膜由五个不同的层组成：A，外部上皮；B，染色质层；C，虹膜细胞层；D、肌层和胶原蛋白丝；E，色素上皮。识别支配括约肌和染色质肌的神经，并描述它们的神经肌肉连接处。色素体神经的运动末梢在突触前位置有一个额外的末梢，它可能是神经肌肉传递的调节剂。染色质体是裸露的，在质膜和色素容器之间呈管状通道系统，类似于肌细胞的t系统。
TheOctopusiris is composed of five different layers: A, the external epithelium; B, the chromatophore layer; C, the iridocyte layer; D, the layer of muscles and collagen strands; E, the pigment epithelium. The nerves innervating the sphincter and the chromatophore muscles are identified and their neuromuscular junction is described. The motor endings of chromatophore nerves have an additional ending in presynaptic position which probably functions as a modifier of neuromuscular transmission. The chromatophores are naked and exhibit a tubular channel system between plasmalemma and pigment container which looks similar to the T-system of muscle cells.
