| tower skull | A type of craniosynostosis in which there is premature closure of the lambdoid and coronal sutures, resulting in an abnormally high, peaked, or conically shaped skull. Synonym: acrocephalia, acrocephaly, hypsicephaly, hypsocephaly, oxycephalia, steeple skull, tower skull, turricephaly. Origin: G. Oxys, pointed, + kephale, head (05 Mar 2000) |

| external base of skull | External aspect of the base of skull Synonym: norma basilaris, basis cranii externa, norma inferior, norma ventralis. (05 Mar 2000) |
| lacunar skull | <radiology> Also known as: craniolacunia, mesenchymal dysplasia, may appear normal after several yrs associated with: Chiari malformation (almost always !), myelomeningocele, encephalocele in contrast, increased intracranial pressure has: beaten-silver appearance, closed sutures, with or without abnormal skull size (Lueckenschaedel) (12 Dec 1998) |
| lateral skull radiograph | A true lateral projection radiograph of facial bones and calvarium, showing bone structures and air-containing passages. (05 Mar 2000) |
| linear skull fracture | A skull fracture resembling a line. (05 Mar 2000) |
| anterior longitudinal ligament | <anatomy> The wide fibrous band interconnecting the anterior surfaces of the vertebral bodies. Synonym: lacertus medius, ligamentum longitudinale anterius. (05 Mar 2000) |
| medial longitudinal arch of foot | Formed by the calcaneus, talus, navicular, three cuneiform bones, and the three medial metatarsals. Synonym: arcus pedis longitudinalis pars medialis. (05 Mar 2000) |
| medial longitudinal bundle | 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) |
| medial longitudinal fasciculus | 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) |
| medial longitudinal stria | A thin longitudinal band of nerve fibres accompanied by gray matter, running along the surface of the corpus callosum on either side of the median line. Together with the lateral longitudinal stria it forms part of a thin layer of gray matter on the dorsal surface of the corpus callosum, the indusium griseum, a rudimentary component of the hippocampus. Synonym: stria longitudinalis medialis. (05 Mar 2000) |
| medial part of longitudinal arch of foot | medial part of longitudinal arch of foot |
| median longitudinal raphe of tongue | <anatomy> Median groove or median longitudinal raphe of tongue; raphe linguae; a slight longitudinal depression running forward on the dorsal surface of the tongue from the foramen caecum. Synonym: sulcus medianus linguae, median longitudinal raphe of tongue, raphe linguae. (05 Mar 2000) |
| great longitudinal fissure | The deep cleft separating the two hemispheres of the cerebrum. Synonym: fissura longitudinalis cerebri, great longitudinal fissure. (05 Mar 2000) |
| posterior longitudinal bundle | 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.
