Where is Malleus bone located in our body?

The correct answer is Middle Ear.

• The Malleus bone is located in our Middle Ear.

Key Points

• The malleus is the outermost and largest of the three small bones in the middle ear and reaches an average length of about eight millimetres in the typical adult.
• It is informally referred to as a hammer, owing to it being a hammer-shaped ossicle or small bone that is connected to the ear.
• It is composed of the head, neck, anterior process, lateral process, and manubrium.
• When sound reaches the tympanic membrane (eardrum), the malleus transmits these sound vibrations from the eardrum to the incus, and then to the stapes, which is connected to the oval window.
• In cases of atticoantral disease, an inflammatory disease of the middle ear, the ossicular chain (malleus, incus, and stapes) is often affected by abnormal skin growth, called cholesteatoma.

Additional Information

• Outer Ear:
  • ​The medical term for the outer ear is the auricle or pinna. The outer ear is made up of cartilage and skin.
  • There are three different parts to the outer ear; the tragus, helix, and lobule. 
• Pinna:
  • The auricle (pinna) is the visible portion of the outer ear. It collects sound waves and channels them into the ear canal (external auditory meatus), where the sound is amplified.
• Middle Ear:
  • ​The middle ear is the portion of the ear internal to the eardrum, and external to the oval window of the inner ear.
  • The mammalian middle ear contains three ossicles, which transfer the vibrations of the eardrum into waves in the fluid and membranes of the inner ear.
