The middle ear is the portion of the ear medial to the eardrum, and distal to the oval window of the cochlea (of the inner ear).. The mammalian middle ear contains three ossicles (malleus, incus, and stapes), which transfer the vibrations of the eardrum into waves in the fluid and membranes of the inner ear.
The ossicles (also called auditory ossicles) are three irregular bones in the middle ear of humans and other mammals, and are among the smallest bones in the human body. . Although the term "ossicle" literally means "tiny bone" (from Latin ossiculum) and may refer to any small bone throughout the body, it typically refers specifically to the malleus, incus and stapes ("hammer, anvil, and ...

Auditory ossicles from a deep dissection of the tympanic cavity Sound waves travel through the ear canal and hit the tympanic membrane, or eardrum . This wave information travels across the air-filled middle ear cavity via a series of delicate bones: the malleus (hammer), incus (anvil) and stapes (stirrup).
The ossicular chain is a crucial structure in the middle ear, responsible for transmitting sound vibrations from the tympanic membrane to the inner ear. This chain consists of three tiny bones: the malleus, incus, and stapes.
The incus is the second of three ossicles, very small bones in the middle ear which act to transmit sound. It is shaped like an anvil, and has a long and short crus extending from the body, which articulates with the malleus. [2]: 862 The short crus attaches to the posterior ligament of the incus.
Around its second to third week, the developing embryo consists of three layers: ectoderm, mesoderm, and endoderm. The first part of the ear to develop is the inner ear, [19] which begins to form from the ectoderm around the embryo's 22nd day, [18] derived from two thickenings called otic placodes on either side of the head.
