It was shown that that axodendritic and axosomatic synapses were characterized by rounded subjunctional bodies, located at the postsynaptic side of the synaptic contact at some distance from postsynaptic density. At the site of the subjunctional densities, the synaptic gap was expanded to 30 μm. In the same synapse, the synaptic gap could be reduced twice or more. Axosomatic and axodendritic synapses occured on spines. On the soma and dendrites of motoneurons, en passant type of synapses were found. No gap junctions were observed.</p></abstract><trans-abstract xml:lang="ru"><p>Проведено исследование ультраструктуры мотонейронов и синапсов в соматической зоне ядер глазодвигательных нервов у мышей С57 Black/6. Показано, что аксодендритные и аксосоматические синапсы характеризуются наличием округлых уплотнений (субконтактные округлые уплотнения), расположенных в постсинаптической части синапса на некотором расстоянии от постсинаптического уплотнения. В месте расположения субконтактных уплотнений синаптическая щель расширена до 30 мкм. В этом же синапсе щель может быть и уменьшена почти в 2 раза. Встречаются аксосоматические и аксодендритные шипиковые синапсы. На соме и дендрите мотонейронов встречаются синапсы типа en passant. Щелевые контакты не обнаружены.</p></trans-abstract><kwd-group xml:lang="en"><kwd>brain</kwd><kwd>oculomotor nuclei</kwd><kwd>motor neurons</kwd><kwd>synapses</kwd><kwd>mouse</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>головной мозг</kwd><kwd>глазодвигательные ядра</kwd><kwd>мышь</kwd><kwd>мотонейроны</kwd><kwd>синапсы</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Корнилова Л.
