Cerebrospinal fluid is a clear liquid that cushions the brain and spinal cord while also transporting nutrients, chemicals, and waste. Dura mater is also the home to meningeal veins. Many types of medical conditions involve the dura mater. The most common come in the form of hematomas. Arterial bleeding can result in an epidural hematoma, which is when blood collects between the dura mater and the skull.
Scientific names: The scientific name of Cerith Snail is Cerithidae genus. Origin or natural range: Cerithidae genus originates from the Caribbean Sea, the Eastern Pacific Ocean including Mexico and Baja California. Size: Cerith Snail may grow up to a size of around one inch.
This phylum is divided into five classes: Asteroidea (sea stars), Ophiuroidea (brittle stars), Echinoidea (sea urchins and sand dollars), Crinoidea (sea lilies or feather stars), and Holothuroidea (sea cucumbers) ([link]). Perhaps the best-known echinoderms are members of the class Asteroidea, or sea stars.
