The term "transverse" refers to something that is situated or extending across something else. In geometry, it describes lines or planes that intersect at right angles to a given direction. For example, a transverse wave in physics moves perpendicular to the direction of energy transfer, such as in light waves. In anatomy, "transverse" often describes a plane that divides the body into upper and lower parts. The transverse plane is essential for understanding human anatomy, as it helps in locating structures and describing movements. This concept is crucial in fields like medicine and physical therapy.
