11( A), (B)) . Each spicule includes a head (manubrium), shaft and blade ( lamina
) , and sometimes the blade has membranous winglike extensions called the
vellum ( Maggenti, 1981) (Figs 4. 10, 4. 11 (B)). Spicules are mobilized by
protractor ...

The most common type of inorganic skeleton is the spicule skeleton, where
individual cells, singly or in groups of up to four, form discrete spicules. These,
according to their morphology and disposition in the sponge, are termed either ...

Preparation. for. spicule. identification. and. histology. Usually sponge
identifications require two forms of preparation: one. a spicule preparation (for

Skeletal Biomineralization: Pattern, Processes, and ...
Spicules are situated in the fibrous connective tissue direcdy under the epidermis
and are surrounded by a spicule-forming cell (Rieger and Sterrer, 1975b). The
composition of these spicules is unknown. However they dissolve in glutar- ...

Molecular Biomineralization: Aquatic Organisms Forming ...
Spicule matrix proteins are also synthesized and secreted by PMCs; thereafter,
the proteins can be found occluded within the mineral phase. The earlier
literature on this subject can be found in the review of Decker and Lennarz (1988
).

Microfacies of Carbonate Rocks: Analysis, Interpretation and ...
Further morphological differentiations use the number of points or rays on the
spicule; resulting terms are often characterized by the root 'actine'. Sponge
spicules may show a central canal (Pl. 112/1). Cross sections of calcitized
spicules can ...

Fourth European Marine Biology Symposium
Finally, the amounts of sodium bicarbonate added in solutions 7-10 were -too
small to enable spicule production to be detected with certainty. There was
certainly no spicule production in solutions 7-9, but in 10, which only slowly
corrodes the ...

For example, an important category of spicules consists of monaxons, formed by
growth along a single axis. If growth occurs in a single direction (indicated by the
presence of one point), the spicule is a monactinal monaxon (plates 17A, ...

Radiolarians in the Sedimentary Record
Radiolarians grow centrifugally (Haeckel, 1887), either radially starting from an
initial spicule in Entactinaria, or from a micro- or macrosphere in Spumellaria, or
unidirectionally along an axis, starting from the initial spicule and the so-called ...
