The visible part is called the auricle, also known as the pinna, especially in other animals.It is composed of a thin plate of yellow elastic cartilage, covered with integument, and connected to the surrounding parts by ligaments and muscles; and to the commencement of the ear canal by fibrous tissue.
The outer ear is the external portion of the ear and includes the fleshy visible auricle, the ear canal, and the outer layer of the eardrum (also called the tympanic membrane). [2] [3] The auricle consists of the curving outer rim called the helix, the inner curved rim called the antihelix, and opens into the ear canal.
The function of the organ of Corti is to convert sounds into electrical signals that can be transmitted to the brainstem through the auditory nerve. [2] It is the auricle and middle ear that act as mechanical transformers and amplifiers so that the sound waves end up with amplitudes 22 times greater than when they entered the ear.
Proper function of the auditory system is required to able to sense, process, and understand sound from the surroundings. Difficulty in sensing, processing and understanding sound input has the potential to adversely impact an individual's ability to communicate, learn and effectively complete routine tasks on a daily basis.

The antihelix (anthelix) is a part of the visible ear; the pinna.The antihelix is a curved prominence of cartilage parallel with and in front of the helix on the pinna.. The antihelix divides above into two legs or crura; the crura antihelicis, between which is a triangular depression, the fossa triangularis.
The oblique muscle of auricle (oblique auricular muscle or Tod muscle [1]) is an intrinsic muscle of the outer ear. The oblique muscle of auricle is placed on the cranial surface of the pinna . It consists of a few fibers extending from the upper and back part of the concha to the convexity immediately above it.
