These bones are connected to each other. The last in the group, stapes, also makes contact with the inner ear.

Which is the smallest bone in the body?

The stapes is the smallest bone in the human body.

Where is the outer ear?

The outer ear consists of the visible portion on the side of the head, known as the pinna [1], and the external auditory canal (ear canal) [2]. The purpose of the pinna is to catch sound waves, amplify them slightly, and funnel them down the ear canal to the tympanic membrane (eardrum) [3].

What are earlobes for?

Since the earlobe does not contain cartilage it has a large blood supply and may help to warm the ears and maintain balance. However, earlobes are not generally considered to have any major biological function. The earlobe contains many nerve endings, and for some people is an erogenous zone.
