A single organule canal or bristle cell secretes a canal cuticle surrounding a narrow canal that allows an environmental outlet for secretion from an organule gland cell or forms a protective sheath around neurites innervating sensory organules, such as mechano- or chemosensory bristles at the surface of the cuticle, as seen in Figure 4A.
3, arrows), most likely deposited along polymer fibrils or bundles laid down by the formative general epidermal and derived organule cells (Lawrence 1966, Merritt 2007).
Calcite itself would not be an effective material choice as a lining of the cuticular organule canals because in the enclosed small diameter (but extended length) of a gland or neurite canal, proton gradients could be established by bacteria that could dissolve a calcite lining easily.
We did not find any particularly enhanced or diminished flux of [Ca.sup.2+] or [H.sup.+] over the organule canal openings, which indicates that they are well surrounded by calcite at the surface, as indicated in Fig.
In mammalian spermiogenesis, marking nucleocytoplasmatic changes and evolutionary alterations of the cytoplasmatic organules involved in the formation of cephalic cap, acrosome, flagellum, round spermatids, elongated spermatids and spermatozoa, are ultra-structurally characterized.
