The upper ear is part of the outer ear, which is medically known as the auricle or pinna.
Understanding the Outer Ear
The outer ear plays a crucial role in collecting and channeling sound waves towards the middle and inner ear. It's composed primarily of cartilage covered by skin, giving it a flexible yet structured form. Let's explore the anatomy and function of this fascinating part of our auditory system.
Auricle/Pinna: The Visible Part of the Ear
The auricle, also called the pinna, is the visible portion of the outer ear. Its intricate folds and curves help to capture sound waves efficiently.
- Function: It funnels sound into the ear canal.
- Composition: Made of cartilage and skin.
Key Components of the Outer Ear
While the question specifically asks about the upper ear, understanding the overall structure provides context.
- Helix: The curved upper rim of the ear. This is what most people would identify as the "upper ear".
- Antihelix: The curved ridge inside the helix.
- Lobe: The soft, fleshy bottom part of the ear.
- Tragus: The small projection in front of the ear canal.
- Concha: The deep cavity leading directly into the ear canal.
Since the question asks "What is upper ear called?", the most accurate and common answer is likely referring to the helix, the curved upper rim. While the entire outer ear is the auricle/pinna, the helix specifically describes the upper portion.
