| I disk | <cell biology> The isotropic band of the sarcomere of striated muscle, where only thin filaments are found. Unlike the A band, the I band can vary in width depending upon the state of contraction of the muscle when fixed. (18 Nov 1997) |

| injury of intervertebral disk | traumatic cervical discopathy |
| intercalated disk | A specialised intercellular attachment of cardiac muscle comprising gap junctions, fascia adherens, and occasionally desmosomes. (05 Mar 2000) |
| intermediate disk | <cell biology> The line formed where actin filaments attach between two sarcomeres. (11 May 1997) |
| interpubic disk | The disk of fibrocartilage that unites the pubic bones at the pubic symphysis. Synonym: discus interpubicus, interpubic disk, lamina fibrocartilaginea interpubica. (05 Mar 2000) |
| intervertebral disk | <anatomy> The intervertebral discs or nucleus pulposus are a fibro-cartilaginous disc that lie between the vertebral bodies in the spine. These disks are composed of a central gelatinous-like material that provide a cushioning or shock absorbing quality to the spinal column to axial stress. Discs may herniate or rupture, resulting in a condition known as a radiculopathy. (27 Sep 1997) |
| intervertebral disk chemolysis | The dissolving of the nucleus pulposus of a displaced intervertebral disk, usually by the direct injection of a proteolytic enzyme, especially chymopapain, into the diseased disk. (12 Dec 1998) |
| intervertebral disk displacement | An intervertebral disk in which the nucleus pulposus has protruded through surrounding fibrocartilage. This occurs most frequently in the lower lumbar region. (12 Dec 1998) |
| isotropic disk | <cell biology> The isotropic band of the sarcomere of striated muscle, where only thin filaments are found. Unlike the A band, the I band can vary in width depending upon the state of contraction of the muscle when fixed. (18 Nov 1997) |
| optic disk | The portion of the optic nerve seen in the fundus with the ophthalmoscope. It is formed by the meeting of all the retinal ganglion cell axons as they enter the optic nerve. Because the retina at the optic disk has no photoreceptors there is a corresponding blind spot in the visual field. (12 Dec 1998) |
| optic disk drusen | Hyaline bodies occurring in the intra-ocular portion of the optic nerve. They are distinguished from retinal drusen, which lie beneath the retinal pigment epithelium. This disorder is differentiated also from papilledema by the absence of dilated retinal vessels. (12 Dec 1998) |
| tactile disk | A specialised tactile sensory nerve ending in the epidermis, characterised by a terminal cuplike expansion of an intraepidermal axon in contact with the base of a single modified keratinocyte. Synonym: meniscus tactus, Merkel's corpuscle, Merkel's tactile cell, Merkel's tactile disk, tactile disk. (05 Mar 2000) |
| temporomandibular articular disk | The fibrocartilaginous plate that separates the joint into upper and lower cavities. Synonym: discus articularis temporomandibularis, mandibular disk, temporomandibular articular disk. (05 Mar 2000) |
| temporomandibular joint disk | A plate of fibrous tissue that divides the temporomandibular joint into an upper and lower cavity. The disk is attached to the articular capsule and moves forward with the condyle in free opening and protrusion. (boucher's clinical dental terminology, 4th ed, p92) (12 Dec 1998) |
| embryonic disk | Germ disk, the point in a telolecithal ovum where the embryo begins to be formed. Synonym: embryonic disk, germinal area, area germinativa. (05 Mar 2000) |
