| 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) |
| sleep spindle | The electroencephalographic record of 14-per-second bursts of wave frequency seen on EEG examination. (05 Mar 2000) |
| spindle | See: mitosis, spindle fibre. (18 Nov 1997) |
| spindle cataract | A cataract in which the opacity is fusiform, extending from one pole to the other. Synonym: fusiform cataract. (05 Mar 2000) |
| spindle cell | A fusiform cell, such as those in the deeper layers of the cerebral cortex. (05 Mar 2000) |
| spindle cell carcinoma | <tumour> A carcinoma composed of elongated cells, frequently a poorly differentiated squamous cell carcinoma which may be difficult to distinguish from a sarcoma. Synonym: sarcomatoid carcinoma. (05 Mar 2000) |
| spindle-celled layer | Layer 6 of the cortex cerebri. Synonym: multiform layer, polymorphous layer, spindle-celled layer. (05 Mar 2000) |
| spindle cell lipoma | <tumour> A microscopically distinctive form of lipoma in which adipose tissue is infiltrated by fibroblasts and collagen; usually found in the shoulder or neck of elderly men. (05 Mar 2000) |
| spindle cell nevus | A benign, slightly pigmented or red superficial small skin tumour composed of spindle-shaped, epithelioid, and multinucleated cells that may appear atypical; most common in children, but also appearing in adults. Synonym: benign juvenile melanoma, epithelioid cell nevus, spindle cell nevus. (05 Mar 2000) |
| spindle cell sarcoma | <tumour> A malignant neoplasm, believed to be of mesenchymal origin, composed of elongated, spindle-shaped cells. Synonym: fascicular sarcoma. (05 Mar 2000) |
| spindle fibre | <cell biology> Microtubules of the spindle that interdigitate at the equatorial plane with microtubules of the opposite polarity derived from the opposite pole microtubule organising centre. Usually distinguished from kinetochore fibres that are microtubules that link the poles with the kinetochore, although these could be included in a broader use of the term. (18 Nov 1997) |
