Definition: Acranium is a term used to describe the top part of the ear, particularly the head which connects the nasal cavity (nasal orifice) with the orbit (outer ear). The acranium typically extends about 5-8 cm from the front of the ear to the back, and it's a flat, rounded organ that is surrounded by skin. The term "acranial" comes from the Greek word "acronis", which means "head". It also refers to the area of the head where the bone responsible for supporting the upper jaw, called the cranium (also known as the maxilla) meets the skull. The definition of the term "acranium" is that it's a region on the head between the nasal cavity and the orbit. It's important because it plays a crucial role in hearing. The acranium allows sound waves to travel from one side of the ear to the other, which helps us hear sounds. In addition, the acranium also connects the upper jaw with the face by way of the nasopharynx (an opening behind the mouth where food and saliva are stored). This connection is essential for chewing, swallowing, and speech.
