| mastoid groove | The groove medial to the mastoid process of the temporal bone from which the digastric muscle originates. Synonym: incisura mastoidea, digastric groove, digastric notch, mastoid notch. (05 Mar 2000) |
| mastoid lymph nodes | Two or three nodes in the region of the mastoid process; they receive afferent lymphatic vessels from the scalp and auricle and send efferent vessels to the superior deep cervical nodes. Synonym: nodi lymphatici mastoidei, mastoid lymph nodes. (05 Mar 2000) |
| mastoid margin of occipital bone | The margin of the occipital squama that articulates with the temporal bone. Synonym: margo mastoideus squamae occipitalis, mastoid margin of occipital bone. (05 Mar 2000) |
| mastoid notch | The groove medial to the mastoid process of the temporal bone from which the digastric muscle originates. Synonym: incisura mastoidea, digastric groove, digastric notch, mastoid notch. (05 Mar 2000) |
| mastoid part of the temporal bone | The portion of the petrous part of the temporal bone bearing the mastoid process. Synonym: pars mastoidea ossis temporalis. (05 Mar 2000) |
| mastoid process | The nipple-like projection of the petrous part of the temporal bone. Synonym: processus mastoideus, mastoid bone, temporal apophysis. (05 Mar 2000) |
| mastoid sinuses | Numerous small intercommunicating cavities in the mastoid process of the temporal bone that empty into the mastoid or tympanic antrum. Synonym: cellulae mastoideae, mastoid cells, mastoid sinuses. (05 Mar 2000) |
| mastoid wall of middle ear | It contains the opening into the mastoid antrum. Synonym: paries mastoideus cavi tympani, mastoid wall of middle ear, posterior wall of middle ear. (05 Mar 2000) |
| anterior auricular branches of superficial temporal artery | <anatomy, artery> Distribution, auricle, earlobe and external acoustic meatus. Synonym: rami auriculares anteriores arteriae temporalis superficialis. (05 Mar 2000) |
| anterior cutaneous branches of intercostal nerves | Medial mammary branches of anterior cutaneous branches of ventral primary rami of thoracic spinal nerves. See: medial mammary branches. (05 Mar 2000) |
| anterior intercostal branches of internal thoracic artery | One of the arteries supplying the anterior portions of the intercostal spaces of the thoracic wall. Anterior intercostal arteries 1-6 arise as branches of the internal thoracic artery; 7-11 arise as branches of the musculophrenic artery. Synonym: rami intercostales anteriores, rami intercostalis anteriores arteria thoracica interna. (05 Mar 2000) |
