通过固蓝 (FB) 逆行运输，在雄性猪中研究了支配球海绵体肌 (BSM) 的神经元的位置、数量和大小。将FB注射到左侧BSM后，在L2-S4交感干神经节（STG）、尾部肠系膜神经节（CMG）、骨盆丛微神经节（PG）、脊髓S1-S3节段中央管的背外侧区域（SC）以及同侧S1-S4神经节中发现标记的神经元。 S2-S3 对侧脊神经节 (SG)。 STG 中标记的 FB 细胞的平均数量为 3,122 +/- 1,968，CMG 中为 979 +/- 667，PG 中为 108 +/- 104，SC 中为 89 +/- 39，SG 中为 77 +/- 23。 STG中多极神经元的面积为852+/-22μm(2)，CMG中为878+/-23μm(2)，PG中为922+/-31μm(2)。多极 SC 神经元的面积为 1,057 +/- 38 μm(2)，而伪单极 SG 细胞的尺寸为 2,281 +/- 129 μm(2)。我们的研究使我们能够强调公猪 BSM 神经支配的两个特点：大量标记的自主神经元和运动体细胞核的特殊定位。 Anat Rec，292：1756-1763，2009。(C) 2009 Wiley-Liss, Inc.
The location, number, and size of the neurons innervating the bulbospongiosus muscle (BSM) were studied in male pigs, by means of Fast Blue (FB) retrograde transport. After injection of FB into the left BSM, labeled neurons were found bilaterally in the L2-S4 sympathetic trunk ganglia (STGs), in the caudal mesenteric ganglia (CMGs), in the microganglia of the pelvic plexus (PGs), in a dorsolateral area with respect to the central canal of S1-S3 segments of the spinal cord (SC) and in the S1-S4 ipsilateral and S2-S3 contralateral spinal ganglia (SGs). The mean number of labeled FB cells was 3,122 +/- 1,968 in STGs, 979 +/- 667 in CMGs, 108 +/- 104 in PGs, 89 +/- 39 in SC and 77 +/- 23 in SGs. The area of the multipolar neurons was 852 +/- 22 mu m(2) in the STGs, 878 +/- 23 mu m(2) in the CMGs and 922 +/- 31 mu m(2) in the PGs. The multipolar SC neurons had an area of 1,057 +/- 38 mu m(2), while pseudounipolar SG cells had dimensions of 2,281 +/- 129 mu m(2). Our research enables us to highlight two peculiarities regarding the innervation of the boar BSM: the very high number of labeled autonomic neurons and the particular localization of the motor somatic nucleus.
