| mastoid branches of posterior auricular artery | <anatomy, artery> Branches from stylomastoid branch of posterior auricular artery arising within the facial canal, distributed to the mastoid air cells. Synonym: rami mastoidei arteriae auricularis posterioris. (05 Mar 2000) |

| great auricular nerve | <anatomy, nerve> Arises from the ventral primary rami of the second and third cervical, spinal nerves, supplies the skin of part of the auricle, adjacent portion of the scalp, and that overlying the angle of the jaw; it also innervates the parotid sheath, conveying from it the pain fibres stimulated by stretching of the sheath during parotitis (mumps). Synonym: nervus auricularis magnus. (05 Mar 2000) |
| right auricular appendage | The small conical projection from the right atrium of the heart. Synonym: auricula dextra, right auricular appendage. (05 Mar 2000) |
| communicating branch of glossopharyngeal nerve with auricular branch of vagus nerve | <anatomy, nerve> A small branch of the glossopharyngeal nerve which joins the auricular branch of the vagus, conveying tactile fibres. Synonym: ramus communicans cum nervo glossopharyngeo, ramus communicans nervi glossopharyngei cum ramo auriculari nervi vagalis. (05 Mar 2000) |
| posterior auricular artery | <anatomy, artery> Origin: posterior aspect of external carotid just above the digastric muscle; course: ascends first between parotid gland and styloid process then between cartilage of auricle and the mastoid process; branches: muscular (digastric, stylohyoid and sternocleidomastoid), glandular (parotid), stylomastoid artery, occipital and auricular; anastomoses: anterior tympanic artery (via the stylomastoid artery) and occipital artery. Synonym: arteria auricularis posterior. (05 Mar 2000) |
| posterior auricular groove | The sulcus between the antitragus and cauda helicis overlying the antitragicohelicine fissure. Synonym: sulcus auriculae posterior. (05 Mar 2000) |
| posterior auricular muscle | <anatomy, muscle> Origin, mastoid process; insertion, posterior portion of root of auricle; action, draws back the pinna; nerve supply, facial. Synonym: musculus auricularis posterior, musculus retrahens aurem, musculus retrahens auriculam. (05 Mar 2000) |
| posterior auricular nerve | <anatomy, nerve> The first extracranial branch of the facial nerve, it passes behind the ear, supplying the posterior auricular muscle and intrinsic muscles of the auricle and, through its occipital branch, innervating the occipital belly of the occipitofrontalis muscle. Synonym: nervus auricularis posterior. (05 Mar 2000) |

| posterior auricular vein | <anatomy, vein> Drains the region posterior to the ear then merges with the retromandibular vein to form the external jugular vein. Synonym: vena auricularis posterior. (05 Mar 2000) |
| posterior branch of great auricular nerve | <anatomy, nerve> Provides general sensory fibres to skin of posterior auricle and over mastoid process. Synonym: ramus posterior nervi auricularis magni. (05 Mar 2000) |
| pyramidal auricular muscle | <anatomy> An occasional prolongation of the fibres of the tragicus to the spina helicis. Synonym: musculus pyramidalis auriculae, Jung's muscle, pyramidal muscle of auricle. (05 Mar 2000) |
| superior auricular | <anatomy, muscle> Origin, galea aponeurotica; insertion, cartilage of auricle; action draws pinna of ear upward and backward; nerve supply, facial. Considered by some to be the posterior part of the temporoparietal muscle. Synonym: musculus auricularis superior, attollens aurem, attollens auriculam, musculus attollens aurem, musculus attollens auriculam. (05 Mar 2000) |
| deep auricular artery | <anatomy, artery> Origin, first part of maxillary; distribution, articulation of jaw, parotid gland, and external acoustic meatus and external tympanic membrane; anastomoses, auricular branches of superficial temporal and posterior auricular. Synonym: arteria auricularis profunda. (05 Mar 2000) |
