| Krukenberg, Adolph | <person> German anatomist, 1816-1877. See: Krukenberg's veins. (05 Mar 2000) |
| Krukenberg, Friedrich | <person> German pathologist, 1871-1946. See: Krukenberg's amputation, Krukenberg's spindle, Krukenberg's tumour. (05 Mar 2000) |
| Krukenberg's amputation | A cineplastic amputation at the carpus with the distal end of the forearm used to create a fork-like stump; especially valuable in the blind because the stump has proprioception. (05 Mar 2000) |
| Krukenberg's tumour | A metastatic carcinoma of the ovary, usually bilateral and secondary to a mucous carcinoma of the stomach, which contains signet-ring cells filled with mucus. (05 Mar 2000) |
| Krukenberg's veins | The terminal branches of the hepatic veins that lie centrally in the hepatic lobules and receive blood from the liver sinusoids. Synonym: venae centrales hepatis, Krukenberg's veins. (05 Mar 2000) |
| krukenberg tumour | <radiology> Ovarian metastasis of stomach carcinoma, also: colon, breast, other mucin-gland organs, 6% of malignant ovarian tumours (12 Dec 1998) |
| aortic spindle | A fusiform dilation of the aorta immediately beyond the isthmus. Synonym: His' spindle. (05 Mar 2000) |
| central spindle | A central group of microtubules (continuous fibres) that course uninterrupted, between the asters, in contrast to the microtubules attached to the individual chromosomes (s. Fibres). (05 Mar 2000) |
| meiotic spindle | The meiotic equivalent of the mitotic spindle. (18 Nov 1997) |
| cleavage spindle | The spindle formed during the cleavage of a zygote or its blastomeres. (05 Mar 2000) |
| mitotic spindle | See: spindle and mitosis. (18 Nov 1997) |
| mitotic spindle apparatus | An organelle consisting of three components: 1) the astral microtubules, which form around each centrosome and extend to the periphery; 2) the polar microtubules which extend from one spindle pole to the equator; and 3) the kinetochore microtubules, which connect the centromeres of the various chromosomes to either centrosome. (12 Dec 1998) |
| muscle spindle | A specialised muscle fibre found in tetrapod vertebrates. A bundle of muscle fibres is innervated by sensory neurons. Stretching the muscle causes the neurons to fire, the muscle spindle thus functions as a stretch receptor. (18 Nov 1997) |
| His' spindle | A fusiform dilation of the aorta immediately beyond the isthmus. Synonym: His' spindle. (05 Mar 2000) |
