seismic wave (sh) and coelomate (medicine)


seismic wave (sh)




Vibration generated by an earthquake, explosion, or similar phenomenon and propagated within the Earth or along its surface.

Earthquakes generate two principal types of waves: body waves, which Travel within the Earth, and surface waves, which Travel along the surface. Seismograms (recorded traces of the amplitude and frequency of seismic waves) yield information about the Earth and its subsurface structure; artificially generated seismic waves are used in oil and gas prospecting.


coelomate (medicine)


coelomate
<embryology> A triploblastic organism which has an internal, fluid-filled body cavity which originated from the mesoderm during embryonic development.

This cavity surrounds the gut, may contain various Other organs, and is called a coelom. It differs from the pseudocoels of the pseudocoelomates because it is not derived from the blastocoel. The term is used to classify multicellular animals by developmental pattern.
