The helicis minor is an oblique fasciculus, covering the crus helicis. The tragicus is a short, flattened vertical band on the lateral surface of the tragus. Also known as the mini lobe. The antitragicus arises from the outer part of the antitragus, and is inserted into the cauda helicis and antihelix.
The helicis major (or large muscle of helix [1]) is an intrinsic muscle of the outer ear. In human anatomy , it is the form of a narrow vertical band situated upon the anterior margin of the helix , at the point where the helix becomes transverse.
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 antitragicus is an intrinsic muscle of the outer ear. In human anatomy, the antitragicus arises from the outer part of the antitragus, and is inserted into the cauda helicis (or tail of the helix) and antihelix. [1] [2] The function of the muscle is to adjusts the shape of the ear by
Auricular sulcus is the depression behind the ear next to the head; Concha is the hollow next to the ear canal; Conchal angle is the angle that the back of the concha makes with the side of the head; Crus of the helix is just above the tragus; Cymba conchae is the narrowest end of the concha; External auditory meatus is the ear canal
The helicis minor is an intrinsic muscle of the outer ear. The muscle runs obliques and covers the helical crus, part of the helix located just above the tragus. The helicis minor originates from the base of the helical crus, runs obliques and inserts at the anterior aspect of the helical crus where it curves upward above the tragus. [1]
The outer ear funnels sound vibrations to the eardrum, increasing the sound pressure in the middle frequency range. The middle-ear ossicles further amplify the vibration pressure roughly 20 times. The base of the stapes couples vibrations into the cochlea via the oval window , which vibrates the perilymph liquid (present throughout the inner ...
