Auricular sulcus is the depression behind the ear next to the head. Aperture is the entrance to the ear canal. Inferior crus (to the right of the fossa triangularis in the diagram). Superior crus (to the left of the fossa triangularis in the diagram). antihelix forms a 'Y' shape where the upper parts are:. The diagram shows the shape and location of most of these components: It is also called the pinna ( Latin for " wing" or " fin", plural pinnae), a term that is used more in zoology. The sensory innervation of the auricle is provided by the great auricular nerve (originating from cervical plexus) supplying the helix, antihelix and lobule of the auricle the lesser occipital nerve (also from cervical plexus) supplying the superior part of the cranial surface of the auricle the auriculotemporal nerve (a branch of the mandibular nerve) innervating the tragus, the crus and the adjacent part of the helix and the auricular branch of the vagus nerve (CN X) together with the posterior auricular branch of the facial nerve (CN VII) supplying small areas of the auricle, innervating the concha, as well as the posterior and superior parts of the eminentia of the concha, which is present on the posterior surface of the auricle.The auricle or auricula is the visible part of the ear that is outside the head. The lymph from the auricle is drained into the superficial parotid, mastoid, deep cervical, and superficial cervical lymph nodes. The veins responsible for the drainage mirror the arteries. The anterior auricular arteries, a branch of the superficial temporal artery. The posterior auricular artery, a branch of the external carotid artery. The auricle is supplied by three arteries: Vasculature and innervation of the auricle Arterial supply and venous drainage The intertragic notch (also called intertragic incisure or intertragal incisure) is a notch between the tragus and antitragus. The antitragus is a small, cartilaginous elevation above the lobule, situated on the inferior continuation of the antihelix and separated from the tragus by the intertragic notch. The base of the tragus is attached to facial skin, while the apex is the one that partially covers the external acoustic opening. The tragus is a flat, triangular, cartilaginous projection in front of the external acoustic opening that starts as the concha of the auricle. The cavity of the concha of the auricle is the main part of the concha located below the crus of the helix and behind the tragus. The cymba conchae of the auricle is the upper, slit-like part of the concha between the crura of the helix and antihelix. It is continuous with the external acoustic meatus. The concha of the auricle is a cavity of the auricle enclosed by the antihelix, antitragus, and tragus. The scapha (or scaphoid fossa) is a fossa located posteriorly between the helix and antihelix. It is the widening of the antihelix that is directed posteriorly toward the helix. The crura of the antihelix are formed by a bifurcation of the antihelix superiorly. The triangular fossa (or fossa triangularis) is an anterosuperiorly located fossa enclosed by the two crura of the antihelix. The antihelix is an arched projection seen on the auricle and situated in front of the posterior part of the helix. The tail of the helix is continuous with the lobule. The tail of the helix is the posterior, inferior end of the helix separated from the antihelix by an indentation. It is the thick, superior part of the helix. 
The spine of the helix is a small cartilaginous prominence projecting forward from the crus. The crus of the helix is the site of origin of the helix situated in the cavity (concha) of the auricle. Inferiorly it ends as soft tissue, also known as the lobule of the auricle. The helix is the external, curved margin of the auricle. The auricle is comprised of the following anatomical features: The lobule of the auricle has no major practical significance.
#Auricula meaning anatomy skin#
The lower 1/3 is the lobule of the auricle (also known as ear lobe) - skin duplicate, which has no cartilage in it and is made of fat tissue.
The auricular cartilage makes up the upper 2/3 of the auricle that is covered by skin. The characteristic shape of the auricle is determined by elastic cartilage forming a structural framework of the auricle, called the auricular cartilage. Auricle by Anatomy Next Structure of auricle The main function of the auricle is to collect, amplify and direct sound waves into the external auditory canal. The auricle is musculocutaneous tissues attached to the skull. The auricle (or pinna, pinna of ear, auricle of ear, auricula, latin: auricula) is the external, visible component of the ear around the outer opening of the ear canal.
