Answer 1

Hint : The function of the ear is to maintain our senses of balance and hearing. Also known as the vestibulocochlear organ, it acts as a receptor and filter, in which auditory stimuli are transformed into information that is subsequently decoded by the brain. The ear is divided into three main parts – the outer ear, the middle ear, and the inner ear.

Complete Step By Step Answer:
The outer ear is called pinna. It is also known as auricle is the visible portion of the outer ear. It collects the sound from the surroundings and passes on to the eardrum through the auditory canal. The vibrations in the eardrum are amplified by three bones known as the ossicles, which are made up of the malleus, the incus, and the stapes. The stapes is the smallest bone in the human body.
The malleus, incus, and stapes also known as the hammer, anvil and stirrup respectively. The outer ear is made up of cartilage and skin. There are three different parts to the outer ear; the tragus, helix and the lobule.

Note :
The stapes is the smallest and lightest bone in the human body, and is so-called because of its resemblance to a stirrup. Femur is the longest, heaviest and strongest bone in the human body. It is located in your thigh (the part of the human leg between the hip and the knee). Clavicle or the collar bone is the softest and weakest bone in the human body.
