The location and local arrangement of the motor, sensory neurons and the primary afferent fibers within the brain stem, the nodosal ganglia, the spinal ganglia, the spinal cord and the sympathetic ganglia projecting to the rat´s heart and the acupoints B14, B5, CV17, H7 and P6 were investigated by the HRP histochemical staining methods and the CTB immunohistochemical methods following injection of 5% WGA-HRP and 1 % CTB into the heart and the acupoints B14, B5, CV17, H7 and P6.
1. The parasympathetic motor neurons innervationg the rat´s heart were founded within the nucleus ambiguus, rostoventral reticular nucleus of reticular formation, dorsal motor nucleus of vagus nerve in the brain stem. The sensory nerve fibers in the brain stem were founded in nucleus tractus solitalius in the caudal portion and area postrema of medulla oblongata The sympathetic motor neurons innervating the rat´s heart were labeled within the left and right stellate ganglia, the left and right T4-79 sympathetic chain ganglia, left side was much more labeled than the right side. The sensory neurons projecting to the rat´s heart were founded in the left and right nodosal ganglia, in the left and right C8-T5 spinal ganglia. The primary afferent fibers projecting to the rat´s heart were labeled in the dorsolateral part, middle part and medial part of lamina IN within the C8-T9 spinal cord segments.
2. The primary afferent fibers projecting to the rat´s acupoints B14, B15 were labeled in the left and right posterior horn of lamina IN within the C8-T7 spinal cord segments, and motor neurons were observed in the left and right anterier horn within the C8-17 spinal cord segments. The sympathetic motor neurons innervating the rat´s acupoints B14, B15 were labeled within the left and right superior cervical ganglia, middle cervical ganglia, stellate ganglia and the left and right T4-T9 sympathetic chain ganglia. The sensory neurons were founded in the T1-6 spinal ganglia.
3. The primary afferent fibers projecting to the rat´s acupoint CV17 were labeled in the left and right posterior horn of lamina II-VI within the C7-T6, and motor neurons were observed in the anterior horn within the C7-T6 spinal cord segments. The sympathetic motor neurons innervating the rat´s acupoint CV17 were labeled within the left and right middle cervical ganglia, stellate ganglia and the left and right T4-T6 sympathetic chain ganglia. The sensory neurons were founded in the T2-5 spinal ganglia.
4. The primary afferent fibers projecting to the rat´s acupoint H7 were labeled in the medial part, middle part of the left and right posterior horn of lamina II-Ⅵ within the C5-T2 spinal cord segments, and motor neurons were observed in the left and right anterior horn within the C8-T1 spinal cord segments. The sympathetic motor neurons innervating the rat´s acupoint H7 were labeled within the left and right middle cervical ganglia, stellate ganglia. The sensory neurons were founded in the C6-T6 spinal ganglia, left side was much labelled than right side.
5. The primary afferent fibers projecting to the rat´s acupoint P6 were labeled in the medial part, middle part of the left and right posterior-horn of_lamina II-Ⅵ within the C5-T2 spinal cord segments, left side was much more labelled than right side, and´ motor neurons were observed in the left and right anterier horn within the C5-T1 spinal cord segments. The sympathetic motor neurons innervating the rat´s acupoint P6 were labeled within the left and right middle cervical ganglia, stellate ganglia. The sensory neurons were founded in the C6-T1 spinal ganglia, left side was much labelled than right side.
This results were neuroanatomically suggested that the location of rat´s motor and sensory neurons innervating the ampoints (B14, B15, CV17, H7 and P6) related to the palpitation were closely related to those innervating the heart.
