It is called the Pinna, or the Auricle.
The visible portion of the ear is shaped in such a way that it best amplifies sound. A pig's ear is large and concave so that it can trap sound waves and amplify them inside the pig's ear for optimum hearing.
The three sections are the outer ear, middle ear, and inner ear. There are links below to the images of the ear's anatomy.
The part of the ear that collects sound waves and directs them into the ear canal is called the pinna, or auricle. It is the visible, outer portion of the ear that serves to capture sound waves from the environment and funnel them toward the ear canal, where they are further processed on their way to the eardrum.
The pinna or auricle is the visible cartilage part of the ear.
The external ear refers to the entire outer portion of the ear, which includes the auricle (or pinna) and the ear canal leading to the eardrum. In contrast, the outer ear specifically denotes the visible part of the ear (the auricle) and does not include the ear canal. Essentially, the external ear encompasses both the auricle and the ear canal, while the outer ear is limited to just the auricle itself.
outer ear
The exterior cartilaginous portion of the outer ear is called the pinna or auricle. It helps collect sound waves and direct them into the ear canal for processing by the ear drum and inner ear structures.
No, typically the underwater portion of an iceberg is not bigger than the portion that is visible above water. Icebergs are known to have a larger portion underwater, but this is due to the difference in density between ice and seawater rather than the underwater portion being larger in size.
Visible light is in the portion of the electromagnetic spectrum between infrared (IR) and ultraviolet (UV) light.
The visible light spectrum (wavelengths from 380 to 700 nanometers)
hair shaft
As a dilated portion of a canal or duct, it is the semicircular canal of the ear
