| facies medialis | The surface of a part of the body that faces toward the midline. The NA recognises a medial surface on the following structures: arytenoid cartilage; fibula; lung; ovary; testis; tibia; ulna. Synonym: facies medialis. (05 Mar 2000) |

| facies medialis cartilaginis arytenoideae | facies medialis cartilaginis arytenoideae |
| facies medialis cerebri | It faces, above as well as anterior and posterior to the corpus callosum, the falx cerebri; below it are the mesencephalon and the dura-covered medial wall of the middle cranial fossa. Synonym: facies medialis cerebri, medial cerebral surface. (05 Mar 2000) |
| facies medialis digiti pedis | The medial surface of a toe. Synonym: facies medialis digiti pedis. (05 Mar 2000) |
| facies medialis fibulae | facies medialis fibulae |
| facies medialis ovarii | The surface of the ovary that faces the pelvic cavity. Synonym: facies medialis ovarii. (05 Mar 2000) |
| facies medialis pulmonis | It consists of a vertebral part and a mediastinal part. See: mediastinal surface of lung. Synonym: facies medialis pulmonis. (05 Mar 2000) |
| facies medialis testis | facies medialis testis |
| facies medialis tibiae | facies medialis tibiae |
| facies medialis ulnae | facies medialis ulnae |
| fasciculus longitudinalis medialis | A longitudinal bundle of fibres extending from the upper border of the mesencephalon into the cervical segments of the spinal cord, located close to the midline and ventral to the central gray matter; it is composed largely of fibres from the vestibular nuclei ascending to the motor neurons innervating the external eye muscles (abducens, trochlear, and oculomotor nuclei), and descending to spinal cord segments innervating the musculature of the neck. Synonym: fasciculus longitudinalis medialis, Collier's tract, medial longitudinal bundle, posterior longitudinal bundle. (05 Mar 2000) |
| fasciculus medialis plexus brachialis | In the brachial plexus, the bundle of nerve fibres formed by the anterior division of the inferior trunk which lies medial to the axillary artery; it gives off the medial pectoral nerve, the medial brachial cutaneous, and medial antebrachial cutaneous, nerves and end by dividing into the medial root of the median nerves and the ulnar nerve. Synonym: fasciculus medialis plexus brachialis. (05 Mar 2000) |
| fossa inguinalis medialis | A depression on the peritoneal surface of the anterior abdominal wall between the ridges formed by the inferior epigastric artery and the medial umbilical ligament; it corresponds to the position of the superficial inguinal ring and is the site of a direct inguinal hernia. Synonym: fossa inguinalis medialis, fovea inguinalis interna. (05 Mar 2000) |
| lemniscus medialis | A band of white fibres originating from the gracile and cuneate nuclei and decussating in the lower medulla; thence it passes upward through the centre of the medulla oblongata, close to the median raphe; on entering the pons it spreads out laterally to form a flat band ascending over the dorsal border of the pontine nuclei; in the mesencephalon it passes over the dorsal border of the substantia nigra and is displaced laterally by the red nucleus; passing medial to the medial geniculate body, the bundle enters and terminates in the ventral posterior nucleus of the thalamus. Throughout their course, the fibres retain a somatotopic order such that those originating from the gracile nucleus and representing the lower extremity lie lateral to those originating in the cuneate nucleus and representing the arm. The medial lemniscus conveys somatic-sensory information involved in tactile discrimination (two-point discrimination), position sense, and vibration sense. Synonym: lemniscus medialis, medial fillet, Reil's band, Reil's ribbon. (05 Mar 2000) |
| ligamentum medialis | <anatomy> The part of the medial or deltoid ligament that extends from the medial malleolus to the neck of the talus. Synonym: pars tibiotalaris anterior ligamenti medialis, anterior talotibial ligament, anterior tibiotalar part of deltoid ligament, ligamentum medialis, ligamentum talotibiale anterius.
