Figure 2 - Exoskeleton – muscle attachment in the dorsal parts of pereonites in adult premolt Ligia italica. Overview of the muscle attachment in a specimen with a detached and a newly forming cuticle (2A a semithin section). The new cuticle is extensively connected to the underlying tendon cells already in the early premolt. Fibrous connections running from the apical region of tendon cells through the new pre-ecdysal cuticle and ecdysal space up to the exocuticle of the detached exoskeleton are evident (2B, C). Parallel arrays of microtubules and apical electron dense plaques are characteristic for tendon cells (2D).
