| 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) |
| loop diuretic | A class of diuretic agents (e.g., furosemide, ethacrynic acid) that act by inhibiting reabsorption of sodium and chloride, not only in the proximal and distal tubules but also in Henle's loop. (05 Mar 2000) |
| loop electrocautery excision procedure | Electrocautery excisional biopsy of abnormal cervical tissue. (05 Mar 2000) |
