Yes, the stapes is the 3rd and final ossicle lying adjacent to the oval window.
The auditory ossicles are located in the middle ear. Their function is to transmit and amplify the sound vibrations from the tympanic membrane (eardrum) to the oval window.
No, the cochlea and ossicles are in different parts of the ear:
The 3 ossicles are "little bones" found in the middle ear. They are the smallest bones in the human body, and each one has its own name:
yes, it is. It's the auditory ossicle known as the hammer.
Typanic membrane
malleus
Pedunculated is attached to the membrane by a stalk. Sessile is sitting directly on the mucous membrane. Fissure is a break.
Sound waves cause the Tympanic Membrane (eardrum) to vibrate, which in turn causes the Malleus (hammer) to transmit those vibrations to the next tiny bone in the ear, called the Incus (anvil). The Incus, in turn, transmits those vibrations to the third small bone in the ear, called the Stapes (stirrup). The Stapes then transmits the vibrations to the membrane of the inner ear, where they can be communicated to the brain for processing and interpretation (hearing).
Its periphery is thickened to form a fibrocartilaginous ring called the annulus tympanicus. The central part of the pars tensa is tented inwards at the level of the tip of malleus and is called the umbo. In other words the outside is thicker with a ring of cartilage and is slightly deeper towards the middle where it is attached to the malleus (ear bone). It is a light pink in color.Its periphery is thickened to form a fibrocartilaginous ring called the annulus tympanicus.

The umbo is the part of the TM where the malleus is attached.

Ear Drum also known as the Typanic Membrane
The malleus is a tiny bone in the middle ear that transmits sound vibrations from the eardrum to the incus (another middle ear bone). This process helps amplify and transfer sound energy to the inner ear, where it is converted into electrical signals that the brain can interpret as sound.

The 3 ossicles are "little bones" found in the middle ear. They are the smallest bones in the human body, and each one has its own name:tympannic side = malleus or hammermiddle = incus or anviloval window side = stapes or stirrupThe most lateral of the ossicles depends on which side your are referring to.

The malleus, incus and stapes are the smallest bones in the human body. Collectively they are the three auditory ossicles of the middle ear.
