Outer Ear (Pinna), Auricular Conch (Auricle)

Outer Ear (Pinna), Auricle (Auricle) - the pinna and the external auditory canal (see figure). In humans, the outer ear is mainly a vestigial organ and does not perform any special functions, but sometimes it can be involved in determining the location of sound sources.

The pinna and external auditory canal make up the human outer ear. Even though the outer ear does not have any special functions, it is still an important organ that helps us sense sounds in our environment.

The pinna (or pinna) is the outer part of the ear and is shaped like a conical cup. It consists of cartilage, which is covered with skin, and has many folds and bulges. These folds and bulges help the ear collect sounds and direct them into the external auditory canal.

The external auditory canal contains a number of hairs and secretory glands that produce wax to protect the ear from dust, dirt and other foreign substances.

Our outer ear is a vestigial organ, i.e. it does not perform any special functions. However, sometimes it can be involved in determining the location of sound sources. For example, when a sound comes from a certain direction, the pinna becomes the center of attention and helps us determine where the sound is coming from.

The outer ear also plays an important role when wearing hearing aids. The hearing aid is placed in the outer ear canal, and the pinna helps hold it in place.

In conclusion, although the outer ear is not the most important organ of hearing, it still performs its functions and helps us perceive sounds in our environment. Learning about the structure and function of the pinna and external auditory canal will help us better understand how our hearing works and how we can protect and improve it.
