The mammillothalamic fasciculus (mammillothalamic tract, thalamomammillary fasciculus, bundle of Vicq d’Azyr) arises from cells in both the medial and lateral nuclei of the mammillary body and by fibers that are directly continued from the fornix. The mammillothalamic fasciculus then connects the mammillary body to the dorsal tegmental nuclei, the ventral tegmental nuclei, and the anterior thalamic nucleus〔Haines, DE. (2003) Neuroanatomy: Atlas of Structures, Sections, and Systems, 6th ed. Lippincott Williams & Wilkins. p232〕 ==Anatomy== The mammillothalamic tract was first described by the French physician, Félix Vicq d'Azyr, from which it takes its alternate name (The Bundle of Vicq d'Azyr). There axons divide within the gray matter; the coarser branches pass into the anterior nucleus of the thalamus as the ''bundle of Vicq d’Azyr'', the finer branches pass downward as the mammillo-tegmental ''bundle of Gudden''. This might be identical to the hypothalamotegmental tract. The bundle of Vicq d’Azyr spreads out fan-like as it terminates in the anterior or dorsal nucleus of the thalamus. A few of the fibers pass through the dorsal nucleus to the angular nucleus of the thalamus. ("The term 'angular thalamic nucleus' refers to a group of cells ventral to the lateral dorsal nucleus in the mouse."〔NeuroNames. Angular Thalamic Nucleus --> ("What, Where and How Big is It?" ) BrainInfo. Accessed January 25, 2011.〕) The axons from these nuclei are supposed to form part of the thalamocortical system. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Mammillothalamic fasciculus」の詳細全文を読む スポンサード リンク
