The tympanic membrane viewed from within. The Umbo is located near the center, denoted as 2.

The umbo is the most depressed part of the tympanic membrane.

Depression

The manubrium of the malleus is firmly attached to the medial surface of the membrane as far as its center, which it draws toward the tympanic cavity; the lateral surface of the membrane is thus concave, and the most depressed part of this concavity is named the umbo.
