A description is presented of the ventromedial nucleus of the hypothalamus (VMN) of sheep following study of paraffin-embedded material stained with a Nissl and a myelin stain. The VMN is related to most structures in the ventrobasal hypothalamus and is ellipsoidally shaped with its poles tilted both medially and anteriorly. Three kinds of neurons can be distinguished under the high power of the light microscope, and other cellular variants are probably the three basic types seen in different orientations. The commonest neuron had bipolar processes and a basophilic line structure apparently curving over the surface of the nucleus. The food and water intake of four sheep with discrete destruction of the VMN is described and compared with sheep with anterior hypothalamic lesions and controls. Discrete destruction of the VMN was without effect on food and water intake. The conclusion is reached that more lateral and ventrolateral areas of the tuberal hypothalamus might be involved in satiety regulation in the sheep.
对用尼氏染色和髓鞘染色的石蜡包埋材料进行研究后，呈现了绵羊下丘脑腹内侧核（VMN）的描述。VMN与腹基底下丘脑的大多数结构相关，呈椭圆形，其两极向内和向前倾斜。在光学显微镜的高倍镜下可区分出三种神经元，其他细胞变体可能是在不同方向上看到的三种基本类型。最常见的神经元有双极突起和一条嗜碱性线状结构，明显在核表面弯曲。描述了四只VMN离散性破坏的绵羊的食物和水摄入量，并与下丘脑前部损伤的绵羊及对照组进行了比较。VMN的离散性破坏对食物和水摄入量没有影响。得出的结论是，下丘脑结节部的更外侧和腹外侧区域可能参与绵羊的饱腹感调节。
