通过整体包埋制备和组织学切片研究了大鼠鼻中隔和嗅球周围的神经支配。采用银染、OsO 4染色、PAS染色、胆碱酯酶反应和含儿茶酚胺神经的荧光染色。终神经在嗅球的内侧形成神经节丛，从该神经节丛发出分支，这些分支与犁鼻神经一起沿外周行进。从终肌神经丛的背侧部分发出前分支，其沿着筛前神经延伸至鼻前庭，在鼻前庭处其与一组神经节连接。神经的外周分支从这里沿着组织学上形成的两个上皮嵴延伸，就像真皮乳头一样。在鼻腔和鼻咽交界处的呼吸区，有一个1 × 2 mm的区域，有嗅上皮、Bowman腺和嗅球的独立神经支配。这就是所谓的隔嗅器三叉神经在呼吸区和前庭形成神经丛，但不供应嗅觉区。含儿茶酚胺和胆碱酯酶阳性神经沿着筛板上的脑膜动脉走行，并伴随其分支到达嗅区和呼吸区的血管丛。不仅在前庭的血管丛中，而且在前庭的肿胀体中的静脉窦中也发现了双重神经支配。鼻子的腺体没有被含儿茶酚胺的神经包围。
The innervation of the nasal septum and around the olfactory bulb has been investigated in rats by means of whole‐mount preparations and histological sections. Silver staining, OsO4staining, PAS staining, cholinesterase reaction and fluorescence for catecholamine‐containing nerves were used. The nervus terminalis forms on the medial side of the olfactory bulb a ganglionated plexus, from which branches are given off which course peripherally with the vomeronasal nerves. From a dorsal part of the terminalis nerve plexus an anterior branch is given off which runs along the anterior ethmoidal nerve to the nasal vestibule where it connects with a group of ganglia. The peripheral branches of the nerve run from here along two epithelial cristae formed histologically like dermal papillae. Ventrally in the respiratory region at the junction of the nasal cavity and the nasopharynx is a 1 × 2 mm area with olfactory epithelium, glands of Bowman and an independent innervation from the olfactory bulb. This is the so‐called septal olfactory organ. Trigeminal nerves form a plexus in the respiratory region and in the vestibule, but do not supply the olfactory region. Catecholamine‐containing and cholinesterase‐positive nerves run along the meningeal arteries on the cribriform plate and accompany their branches to the vascular plexus in the olfactory and respiratory regions. Double innervation is found not only of this vascular plexus but of the venous sinuses in the swell bodies of the vestibule. The glands of the nose are not surrounded by catecholamine‐containing nerves.
