The meaning of SPICULE is a slender pointed usually hard body; especially : one of the minute calcareous or siliceous bodies that support the tissue of various invertebrates (such as sponges). Each bone has two types of bone tissue to ensure strength: The dense, hard outer layer is called compact or cortical bone while the inner, less dense, lattice-like bone is called cancellous, trabecular or spongy bone that is surrounded by bone marrow. They can occur anywhere in the body, but they’re most common in joints and tend to be seen in older adults. This eventually leads to the degeneration of the outer retina, causing direct contact with the inner retinal vessels and migration of the RPE cells. 8-μm thick frozen sections were reacted with polyclonal silicatein antibodies. g. Electroretinograms help confirm the diagnosis by demonstrating attenuated rod and cone signals.

The cross sections show the circular axial canal (ac) and the lamellated siliceous deposits which surround the canal. In a related procedure, known as a bone marrow aspiration, bone marrow is drawn into a syringe as a liquid that looks like blood but contains white particles known as bone “spicules. Composed primarily of silica or calcium carbonate, sponge spicules come in a variety of shapes and sizes, each uniquely adapted to the specific The onset and pattern of degeneration vary, but most cases demonstrate atrophy of the retina and retinal pigment epithelium, bone spicule pigmentation, waxy pallor of the optic nerves, and retinal vascular attenuation.
