The structure that collects sound and funnels it into the auditory canal is called the pinna.
The ear is an exposed and sensitive organ in the human body. It is concerned with collecting, transmitting, and producing sounds. It also helps to maintain balance in the body. It has three main parts: the external ear, the middle ear, and the internal ear. Pinna is a part of the external ear.
Pinna is also called auricle. It is composed of cartilage folds that are covered by skin. The only part of the audible which is not covered by cartilage is the lobule. The curvature formed by cartilage is known as a helix. Another part of the pinna includes the meatus which is responsible for directing sounds collected by the helix.
Pinna acts as a link that transfers sound signals from the air to the auditory canal inside the ear. The tympanic membrane carries the sounds in an S-shaped path towards the middle ear (auditory canal).
