    The aesthetes of chitons (1974)
    Springer
    Cell & tissue research 153 (1974), S. 383-398 
    Details
    ISSN: 1432-0878
    Keywords: Aesthete Organs ; Lepidochitona cinereus ; Cell types ; Secretory cells ; Light and electron microscopy

    Topics: Biology , Medicine
    Notes: Summary The structure of the aesthete organs of the chiton Lepidochitona cinereus (L.) is described by light and electron microscopy. The observations do not discount a sensory function for these organs, but possible sensory structures such as microvilli and cilia are poorly organised. Most of the aesthete is taken up with large cells actively forming secretory products and apparently passing them proximally in the aesthete canal towards the animal. Comparisons are drawn with the brachiopod caecae.

    Fine structure of the eyes of Onithochiton neglectus (Mollusca: Polyplacophora) (1969)
    Springer
    Cell & tissue research 102 (1969), S. 313-332 
    Details
    ISSN: 1432-0878
    Keywords: Mollusca ; Chitons ; Photoreceptor ; Fine Structure ; Cilia

    Notes: Summary Onithochiton neglectus a common littoral chiton possesses large numbers of small eyes embedded in the outer layer of the shell, the tegmentum. These are arranged in a definite pattern on each shell valve. Each eye lies in a pocket, and is surrounded by pigment laid down in the shell. There is a lens, cup of retina cells and an optic nerve running in an optic canal through the shell. Glial elements are present. The retina cells give rise centrally to a packed array of microvilli, a rhabdom. Cilia are present at the edge of the rhabdom; they have a 9 + 2 arrangement of ciliary filaments and do not appear to be involved in the formation of microvilli. Cells at the periphery of the eye cup give rise to large whorls of membranes, lamellate bodies. These bodies are derived from the membranes of cilia having a 9 + 2 pattern, and form into an extra-cellular space. Nerve processes from the retina cells pass into the optic canal. On the basis of previous work it is thought that the lamellate bodies are also sensory. These structures are discussed in relation to other microvillar and lamellate structures described from photoreceptors.
