| Obersteiner-Redlich zone | The narrow line along the course of a nerve (or nerve root) where the Schwann cells and connective tissue that support its axons are replaced by glia cells. The zone marks the true boundary between the central and the peripheral nervous system. Usually located at or near the surface of the spinal cord or brainstem, it can extend (e.g., in the eighth nerve) several millimeters out along the nerve. Synonym: Obersteiner-Redlich line.

| thymus-dependent zone | <anatomy> Mid cortical region of lymph node, area that is particularly depleted of T lymphocytes in thymectomised animals and is referred to as the thymus dependent area. (18 Nov 1997) |
| trabecular zone | The network of fibres (pectinate ligaments) at the iridocorneal angle between the anterior chamber of the eye and the venous sinus of the sclera; it contains spaces between the fibres that are involved in drainage of the aqueous humor, and is composed of two portions: the corneoscleral part, the part attached to the sclera, and the uveal part, the part attached to the iris. Synonym: reticulum trabeculare sclerae, Gerlach's valvula, Hueck's ligament, ligamentum annulare bulbi, pectinate ligaments of iridocorneal angle, pillar of iris, trabecular meshwork, trabecular network, trabecular zone.

| transitional zone | The equatorial region of the lens of the eye where the anterior epithelial cells become transformed into lens fibres, that portion of a scleral contact lens between the corneal and scleral sections. (05 Mar 2000) |
| entry zone | The area of the dorsal funiculus of the spinal cord, medial to the tip of the posterior horn, in which the entering fibres of the posterior nerve root divide into ascending and descending branches. (05 Mar 2000) |
| ependymal zone | An inner epithelial layer of cells bordering the lumen of the embryonic neural tube and brain, formed during the latter's stratification, and persisting in modified form throughout life. Synonym: ependymal zone, ventricular layer. (05 Mar 2000) |
