Lateral surface of the auricle
About this plate
Lateral surface of the auricle.
The external ear, or auricle, is the visible cartilaginous appendage of the outer ear, paired on either side of the head and shaped to funnel sound toward the external acoustic meatus. From the lateral aspect its elastic cartilage forms a series of curved ridges and hollows. The outer rim is the helix, sweeping around a parallel inner ridge, the anti-helix, and the narrow furrow between them is the scapha. Anteriorly the anti-helix divides into two crura enclosing the fossa triangularis. Centrally lies the concha, guarded in front by the tragus and behind by the anti-tragus. Inferiorly hangs the fleshy, non-cartilaginous lobule.
