Any of the terminal or smaller branches of an axon that terminates with specialized ending that releases neurotransmitters. Telodendria originally refer to the terminal branches of dendrites, now they refer to the main or terminal arborization of an axon. Word origin: Greek tÃ©los (end) + Greek dÃ©ndron (tree).
Permineralization is one of the ways in which a plant or animal can be turned into a fossil. During this process, mineral rich water seeps into the void spaces of an organism, leaving deposits of minerals behind that slowly build up, creating a cast of the organism.
The most common method of fossilization is called permineralization, or petrification. After an organism's soft tissues decay in sediment, the hard parts â particularly the bones â are left behind. Water seeps into the remains, and minerals dissolved in the water seep into the spaces within the remains, where they form crystals.
