| buffy coat | <haematology> Thin yellow white layer of leucocytes on top of the mass of red cells when whole blood is centrifuged. (18 Nov 1997) |
| coat | 1. The outer covering or envelope of an organ or part. 2. One of the layers of membranous or other tissues forming the wall of a canal or hollow organ. See: tunic. (05 Mar 2000) |
| coat protein | <protein> The proteins which make up the outer coat of a virus (called the capsid). (09 Oct 1997) |
| sclerotic coat | <anatomy> The tough white outer coat of the eyeball, covering approximately the posterior five sixths of its surface and continuous anteriorly with the cornea and posteriorly with the external sheath of the optic nerve. Origin: L., Gr. Skleros = hard (18 Nov 1997) |
| serous coat | serous membrane |
| egg coat | A layer of glycoproteins and other stuff which surrounds an egg (ovum), just outside of the egg's cell membrane. The coat protects the egg, and for organisms which practice external fertilization (fertilization outside of the parents' bodies) it can help prevent the sperm of other species from entering the egg. For the eggs of mammals, the egg coat is called the zona pellucida and for sea urchins (a popular study organism for developmental biologists) it is called the vitelline layer. (09 Oct 1997) |
| 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) |
