Original Ultrastructure Of Cement Lines

The destruction of the ostracod carapace ultrastructure indicates the dissolution of the neomorphic calcitic carapace before dolomite precipitation, possibly by hot hydrothermal fluids. 5.1.5. Stage 5. Only a remnant of the original multilaminate carapace structure remains, and is seen by siderite mineralisation.

    The ultrastructure of cement glands in a rhabdocoel

    The cement glands of a rhabdocoel turbellarian, Syndisyrinx sp., were examined by transmission electron microscopy. The glands appear as large, flattened secretory cells with a cell body and elongate, thin cytoplasmic processes that extend to the female antrum. Presecretory granules are released from the Golgi complex into filling vesicles until these vesicles are essentially full before
