| neutral zone | In dentistry, the potential space between the lips and cheeks on one side and the tongue on the other; natural or artificial teeth in this zone are subject to equal and opposite forces from the surrounding musculature. (05 Mar 2000) |
| subplasmalemmal dense zone | An electron-dense, 10-15 nm thick layer of highly cross-linked protein on the cytoplasmic surface of the cell membrane of epidermal corneocytes; it is highly resistant to proteolytic agents. Synonym: subplasmalemmal dense zone. (05 Mar 2000) |

| interpalpebral zone | The exposed area of the cornea and sclera between the lids of the open eye. (05 Mar 2000) |
| intertubular zone | The dentinal matrix which lies between zone's of peritubular dentin; it is less calcified and contains larger collagen fibres than does peritubular dentin. (05 Mar 2000) |

| 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.

| orbicular zone | Fibres of the articular capsule of the hip joint encircling the neck of the femur. Synonym: orbicular zone, ring ligament, zonular band. (05 Mar 2000) |
| 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.
