additional information | localization and distribution of nitric oxide synthase and other neuronal markers in the podia of Holothuria arguinensis, detailed overview. The podia terminal end is the most specialized area and is characterized by a specific nervous arrangement, consisting of a distinct nerve plate, rich in cells and fibers containing potential sensory cells staining positively for neuronal markers. In sea cucumbers, cells with morphological characteristics typical of sensory cells have been described in the tentacles, tube feet, and papillae. NADPH-diaphorase histochemistry and NOS immunohistochemistry. The NADPH-diaphorase staining and the anti-NOS antibody show an overall similar distribution in the tentacle. In the stem, the longitudinal buccal nerve and the buccal nerve are strongly reactive to both markers. The mesothelium is also positive for NADPH-d and anti-NOS. In the bud, the two methods reveal that NOS is present in both the buccal nerve and mesothelium | Holothuria arguinensis | - |

physiological function | nitric oxide (NO) is synthesized from L-arginine by the NADPH-dependent enzyme nitric oxide synthase (NOS), and is involved in many essential biological functions including immune defense, vascular regulation, muscle relaxation, and neuromodulation, and neurotransmission | Holothuria arguinensis |
