| trapezoid bone | A bone in the distal row of the carpus; it articulates with the second metacarpal, trapezium, capitate, and scaphoid. Synonym: os trapezoideum, lesser multangular bone, os multangulum minus, trapezoid. (05 Mar 2000) |

| ventral nucleus of trapezoid body | A cell group embedded among the fibres of the trapezoid body, the major decussation of the central auditory pathway, in the lower pons. The nucleus receives fibres from the contralateral cochlear nuclei and contributes fibres to the ascending auditory system or lateral lemniscus. Synonym: nucleus ventralis corporis trapezoidei. (05 Mar 2000) |
| dorsal nucleus of trapezoid body | A circumscript, bipartite cell group located ventrolaterally in the lower pontine tegmentum, immediately dorsal to the trapezoid body; the nucleus receives fibres from both the ipsilateral and contralateral cochlear nuclei, and contributes fibres to the lateral (auditory) lemniscus of both sides. It is believed to be prominently involved in the function of spatial localization of sound. Synonym: nucleus dorsalis corporis trapezoidei, oliva superior, superior olivary nucleus, superior olive.

| trapezoid | 1. <geometry> A plane four-sided figure, having two sides parallel to each other. 2. <anatomy> A bone of the carpus at the base of the second metacarpal, or index finger. Origin: Gr. Trapezoid-shaped; table + shape, likeness: cf. F. Trapezoide. See Trapezium. 1. Having the form of a trapezoid; trapezoidal; as, the trapezoid ligament which connects the coracoid process and the clavicle. 2. <anatomy> Of or pertaining to the trapezoid ligament; as, the trapezoid line.

| trapezoid body | A plate of transverse fibres running over the dorsal (deep) border of the pontine nuclei; it is formed by ascending auditory fibres that cross to the opposite side of the brainstem. Synonym: corpus trapezoideum, trapezoid. (05 Mar 2000) |

| Henle, Friedrich | <person> German anatomist, pathologist, and histologist born in Furth, near Nuremberg, 1809. He was a student and Prosector of Anatomy in Berlin and became Professor of Anatomy in Zurich in 1840. In 1844 went to Heidelberg. From 1852 until his death was professor of Anatomy in Gottingen. Was one of the most celebrated German Anatomists of Jewish descent, well known for his many contributions to microscopic anatomy. D. 1885. Henle's Loop - the looped portion of the uriniferous tubules of the kidney. Allgemeine Anatomie. Leipzig. 1841. Systematiche Anatomie. Brunswick. 1855. Many other structures are associated with Henle's name and more than twenty ligaments were named by him. Lived: 1809-1885.

| Henle's ampulla | The dilation of the ductus deferens where it approaches its contralateral partner just before it is joined by the duct of the seminal vesicle. Synonym: ampulla ductus deferentis, Henle's ampulla. (05 Mar 2000) |
| Henle's ansa | 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) |
