Figure 3. Nymphopsis spinosissima. Oblique section through a myocuticular junction. At the bottom of the field, two muscle cells are still lying in the hemocoel, but are beginning to subdivide into the terminal pegs before interlocking with tendinal cells.Two large, tubuliferous tendinal cells in the center of the image are junctioned with muscle cells at the lower surface and are attached to anchoring filaments at the upper, cuticular side. The latter specialization is indicated by a punctate region under the endocuticle. Note that the left tendinal cell extends basally beyond the right one, showing that even these cells participate in the complex interlockings common to epidermal cells. 12,000x
