^BBartolomeo Eustachio.^b Portrait of Bartolomeo Eustachio (1524-74), Italian anatomist. Eustachio researched the teeth, ear, kidneys, uterus, cranial nerves and muscles of the head and neck. He discovered the adrenal glands, a valve in the heart and a tube linking the inner ear to the throat. The heart valve and ear tube were named ‘Eustachean’ after him. In 1564 he published ^IOpuscula anatomica ^i(Anatomical Works). Another work ^ITabulae Anatomicae^i (Anatomical Drawings) which contains detailed illustrations like those of Vesalius, remained undiscovered until 1714. Eustachio was an opponent of the work of Vesalius, favouring instead the theories of Galen.
