| endosonography | Ultrasonography of internal organs using an ultrasound transducer sometimes mounted on a fibreoptic endoscope. In endosonography the transducer converts electronic signals into acoustic pulses or continuous waves and acts also as a receiver to detect reflected pulses from within the organ. An audiovisual-electronic interface converts the detected or processed echo signals, which pass through the electronics of the instrument, into a form that the technologist can evaluate. The procedure should not be confused with endoscopy which employs a special instrument called an endoscope. The "endo-" of endosonography refers to the examination of tissue within hollow organs, with reference to the usual ultrasonography procedure which is performed externally or transcutaneously.

| endosperm | Tissue present in the seeds of angiosperms, external to and surrounding the embryo, that it provides with nourishment in the form of starch or other food reserves. Formed by the division of the endosperm mother cell after fertilization, may be absorbed by the embryo prior to seed maturation or may persist in the mature seed. (18 Nov 1997) |
