本文采用多种组化方法结合神经银染技术,对大鼠的食管颈段神经形态观察发现:延髓内双侧疑核的咀侧端及迷走神经背核闩平而附近,分别见散在的多极和梭形标记细胞;颈前、中节、颈胸节和胸交感节(T_2-T_4),结状节,脊神经节(C_2-C_8)内均见标记细胞。 食管壁内的神经束及分支,由粗、细两类神经纤维组成。其中AchE阳性的胆碱能纤维占优势,分别见于外膜丛、肌内丛、粘膜下丛,腺体血管周围和粘膜肌内,粗纤维末梢伸向上皮基部和上皮之间,肌内的神经末梢呈结状膨大。外膜和肌肉见有神经节和散在的神经细胞。而食管壁内肾上腺素能纤维稀少,仅见于神经束和分支内及血管壁周围。
In this paper, a variety of histochemical methods combined with neural silver staining of the rat esophageal neck nerve morphology was found: medullary medullary double-suspect nuclear Tsui side of the vagus nerve dorsal nucleus and the vaginal nerve near the flat, respectively, see scattered multi-pole And spindle-labeled cells. The labeled cells were found in the anterior, middle, cervical and thoracic sympathetic joints (T 2 -T 4), nodose and spinal ganglia (C 2 -C 8). The nerve bundle and branches in the esophageal wall consist of coarse and fine nerve fibers. Among them, AchE-positive cholinergic fibers predominate, which are found in the epicardial plexus, intramuscular plexus, submucosal plexus, glandular vessels and mucosa intramuscularly, the ends of crude fiber extend to the base of epithelium and epithelium, the intramuscular nerve Terminal was knot enlargement. See the adventitia and muscle ganglia and scattered nerve cells. Adrenergic fibers in the esophageal wall are scarce, found only in the nerve bundles and branches and around the vessel wall.
