“Few long marginalia projecting from the oscular margin may belong to an oscular spicule rim.”

“The central point of the spicule positioned very close to the innermost shell wall.”

“For bone marrow it is important that a first draw, spicule rich sample be collected.”

“Typical findings include spiculation of the mucosa, spasm, abscess, or evidence of frank perforation.”

“Mammography generally does not demonstrate a distinct mass, spiculation or microcalcification.”

“The dorsal conic spine-like structures could be a homology of cuticular spicules of polyplacophorans and aplacophorans.”

“If collar cells and spicules are defining characteristics of the Phylum Porifera, then nematocysts define cnidarians.”

“Brittle stars also have pluteus larvae with skeletal spicules that resemble those of the urchin.”
