#auricul
- Antehelix — A curved prominence of the external ear pinna, situated in front of and parallel to the helix, separated from it by the scaphoid fossa. This cartilaginous structure bifurcates in its upper part into two flexible crura that frame the triangular fossa, playing an essential role in capturing, reflecting, and guiding sound waves toward the external auditory canal.
- Antitragus — A small, cartilaginous prominence located on the pinna of the external ear (auricle), situated symmetrically at the lower part of the antihelix and placed directly opposite the tragus, from which it is separated by the intertragic notch. This fine anatomical structure plays a decorative and functional role in helping direct sound waves into the external auditory canal and also represents a common landmark in modern piercing procedures.
- Antromastoiditis — An acute or chronic bacterial inflammatory and infectious condition affecting simultaneously the mucosa and bony structure of the mastoid antrum and the neighboring mastoid cells. It usually represents a severe complication of suppurative otitis media, clinically characterized by intense retroauricular pain, high fever, local erythema, and purulent discharge, requiring aggressive antibiotic treatment or surgical drainage.
- Auricle — An anatomical pouch-like or small sac structure located on the upper part of each of the two cardiac atria (left and right auricles), serving to increase blood storage capacity. In zoology and comparative anatomy, the term also denotes the pinna of the external ear in mammals or a lateral prolongation in certain invertebrates.
- Auricle — A prominent anatomical pouch-like or ear-shaped structure attached to the cardiac atria, serving to increase their volumetric capacity; a feminine variant commonly found in older treatises for 'auricul'. In botany, it denotes a small rounded lobe located at the base of certain leaves or petals, partially clasping the stem.
- Auriculaefolia — Feminine singular form of a compound adjective used in botanical binomial nomenclature to describe a plant species whose leaves have a distinct shape resembling small ears, an auricle, or the foliage of Primula auricula.
- Auricular — Pertaining to the ear or the cardiac auricle; auditory. As a masculine noun, it designates the pinky finger (named so because its size fits the external auditory canal). In linguistics and historical theology, it describes a confession made directly into someone's ear (e.g., auricular confession).
- Wood ear — A genus of basidiomycete fungi within the family Auriculariaceae, characterized by gelatinous, lobed fruiting bodies whose shape resembles the human ear pinna (such as Auricularia auricula-judae, popularly known as Judas's ear or wood ear, widely used in Asian cuisine).
- Auriculate — Provided with small ear-shaped lateral appendages or rounded lobes at the base. In botany, it describes a leaf or plant organ displaying two small lobes at the insertion point on the petiole; in zoology, it refers to shells or anatomical structures equipped with auricular expansions.
- Auricles — The unarticulated plural form of the masculine noun 'auricul' (atrial appendages or ear pinnas), primarily used in older medical terminology or in regional graphic variants that assimilate the noun into the masculine declension paradigm.
- Auriculiform — Having the shape of an ear, an auditory pinna, or a cardiac auricle. In plant morphology, the term describes leaves, petals, or fungi whose margins and lobes mimic the contour of human ears; in zoology, it applies to shells or calcareous structures with a symmetrically lobed profile.
