| Henle's loop | The U-shaped part of the nephron extending from the proximal to the distal convoluted tubules, consisting of descending and ascending limbs, located in the medulla renalis and medullary ray. Synonym: Henle's ansa, Henle's loop. (05 Mar 2000) |

| sentinel loop sign | In gastrointestinal radiology, dilatation of a segment of large or small intestine, indicative of localised ileus from nearby inflammation. (05 Mar 2000) |
| Hyrtl's loop | A communicating loop between the right and left hypoglossal nerves, lying between the geniohyoid and genioglossus muscles or in the substance of the geniohyoid; it is found in about one in ten persons. Synonym: Hyrtl's anastomosis. (05 Mar 2000) |
| stem and loop structure | <molecular biology> The structure of tRNAs is so termed because it has four base paired stems and three loops (not base paired), one of which contains the anticodon. (18 Nov 1997) |
| nephronic loop | The U-shaped part of the nephron extending from the proximal to the distal convoluted tubules, consisting of descending and ascending limbs, located in the medulla renalis and medullary ray. Synonym: Henle's ansa, Henle's loop. (05 Mar 2000) |
| subclavian loop | A nerve cord connecting the middle cervical and stellate sympathetic ganglia, forming a loop around the subclavian artery. Synonym: subclavian loop, Vieussens' ansa, Vieussens' loop. (05 Mar 2000) |
| displacement loop | <molecular biology> A structure that can sometimes be seen on DNA which forms when a small area of the double-stranded molecule comes apart and becomes two single strands. The result is a structure shaped like the letter D. Single-stranded binding proteins are usually present to hold the strands apart for the purpose of DNA replication. (09 Oct 1997) |
| d loop | <molecular biology> A structure that can sometimes be seen on DNA which forms when a small area of the double-stranded molecule comes apart and becomes two single strands. The result is a structure shaped like the letter D. Single-stranded binding proteins are usually present to hold the strands apart for the purpose of DNA replication. (09 Oct 1997) |
| double loop hernia | The presence of two loops of intestine in a hernial sac. Synonym: double loop hernia. (05 Mar 2000) |
| Ivy loop wiring | Placement of a wire around two adjacent teeth to provide an attachment for intermaxillary elastics. (05 Mar 2000) |
| T loop of RNA | <molecular biology> The T loop of tRNA is the region of the molecule that is responsible for ribosome recognition. (16 Dec 1997) |
| Tphi CG loop | <molecular biology> The T loop of tRNA is the region of the molecule that is responsible for ribosome recognition. (16 Dec 1997) |
| lenticular loop | The pallidal efferent fibres curving around the medial border of the internal capsule. Synonym: ansa lenticularis, lenticular ansa. (05 Mar 2000) |
| loop | 1. A fold or doubling of a thread, cord, rope, etc, through which another thread, cord, etc, can be passed, or which a hook can be hooked into; an eye, as of metal; a staple; a noose; a bight. "That the probation bear no hinge, nor loop To hang a doubt on." (Shak) 2. A small, narrow opening; a loophole. "And stop all sight-holes, every loop from whence The eye of Reason may pry in upon us." (Shak) 3. A curve of any kind in the form of a loop. 4. A wire forming part of a main circuit and returning to the point from which it starts. 5. <physics> The portion of a vibrating string, air column, etc, between two nodes; called also ventral segment. Loop knot, a single knot tied in a doubled cord, etc. So as to leave a loop beyond the knot. Origin: Cf. Ir. & Gael. Lub loop, noose, fold, thong, bend, lub to bend, incline.

| loop bioreactors | Bioreactors in which the fermenting material is cycled between a bulk tank and a smaller tank or loop of pipes. The circulation helps mix the materials and ensures that gas injected into the fermenter is well distributed. (14 Nov 1997) |
