ANATOMY

Detailed explanation-1: -It collects sound waves and channels them into the ear canal (external auditory meatus), where the sound is amplified. The sound waves then travel toward a flexible, oval membrane at the end of the ear canal called the eardrum, or tympanic membrane.

Detailed explanation-2: -The pinna is the part of the ear you see on the side of your head and is made of tough cartilage covered by skin. Its main job is to gather sounds and funnel them to the ear canal, which is the pathway that leads to the middle ear.

Detailed explanation-3: -It is the first part of the outer ear’s anatomy that reacts to sound. The pinna’s function is to act as a kind of funnel which assists in directing the sound further into the ear. Without this funnel the sound waves would take a more direct route into the auditory canal.

Detailed explanation-4: -The outer ear is composed of the visible part of the ear (pinna) and the ear canal. The cup-shaped pinna (PIN-uh) gathers sound waves from the environment and directs them into the ear canal.

Detailed explanation-5: -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 the lobule.
