Adam's apple

Definition 
Adam never ate an apple, at least not in the biblical account of his transgressions, which refers only to unspecified forbidden fruit on the tree in the Garden of Eden. The forbidden fruit of which the Lord said "Ye shall not eat of the fruit which is in the midst of the garden, neither shall ye touch it, lest ye die" (Gen. 3:3) was probably an apricot or pomegranate, and the Muslims—intending no joke—believe it was a banana. Many fruits and vegetables have been called apples. Even in medieval times, pomegranates were "apples of Carthage"; dates, "finger apples"; and potatoes, "apples of the earth." At any rate, tradition has it that Adam succumbed to Eve's wiles and ate of an apple from which she took the first bite, that a piece stuck in his throat forming the lump we call the Adam's apple, and that all of us, particularly males, inherited this mark of his "fall." Modern scientific physiology, as opposed to folk anatomy, explains this projection of the neck, most prominent in adolescents, as being anterior thyroid cartilage of the larynx. But pioneer anatomists honored the superstition in the mid-18th century by calling it pomum Adami, or Adam's apple. They simply could find no other explanation for this evasive lump in the throat that even seemed to move up and down.
