Cavernous hemangioma, also called cavernous angioma, venous malformation, or cavernoma, [1] [2] is a type of venous malformation due to endothelial dysmorphogenesis from a lesion which is present at birth. A cavernoma in the brain is called a cerebral cavernous malformation or CCM.
Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor.These particles either have their origins in soil and rocks and have been transported from the land to the sea, mainly by rivers but also by dust carried by wind and by the flow of glaciers into the sea, or they are biogenic deposits from marine organisms or from ...
Biogenous material is the sediment made up of the hard parts of sea creatures, mainly phytoplankton, that accumulate on the bottom of the ocean. Hydrogenous sediment is material that precipitates in the ocean when oceanic conditions change, or material created in hydrothermal vent systems.
A millimeter-sized sea animal could hold clues to the evolution of the human nervous system. While placozoans are simple animals only as big as a grain of sand, the blobs have unique cells that ...
Bunodosoma cavernatum is native to the tropical and subtropical western Atlantic Ocean and the Caribbean Sea, its range extending from North Carolina to Texas, including Florida and the West Indies. It occurs in the lower part of the intertidal zone on rocks and jetties, and on other hard substrates underlying gravelly or sandy bottoms.
Researchers have discovered a megastructure in the Baltic Sea that was likely once used by hunter-gatherers to hunt reindeer nearly 11,000 years ago.
The brine pools were found 4,000 feet below the surface of the Gulf of Aqaba, where the water is estimated to be up to 10 times saltier than ... Shocking deep sea discovery made in area where ...
Massive accumulations of turbidites and other deep-water deposits may result in the formation of submarine fans. Sedimentary models of such fan systems typically are subdivided into upper, mid, and lower fan sequences each with distinct sand-body geometries, sediment distributions, and lithologic characteristics.
