Fragments of rock or lava that are sent into the air in a volcanic explosion are called tephra.

Explanation:

The volcanoes come in different shapes and sizes, and with them come different types of eruptions as well. Some volcanoes have explosive eruptions, some mainly release ashes and gasses, while some erupt with lava flows. The volcanoes that have explosive eruptions release a lot of pyroclastic material often propelled high and wide around them.

Part of the pyroclastic material that is released is the tephra. Tephra is basically represented by fragments of very hot rock and lava that are shoot into the air during a volcanic eruption. The tephra is extremely dangerous, as it can be shoot out over a distance of several km, and being very heavy, very hot, and moving at very high speed, when it hits something it manages to destroy it or cause enormous damage, and if it is a living organism that is hot it will mean the end of it for sure.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
