Hind Limb Sensory Innervation in Rats: Comparison between Sural and Saphenous Nerve Morphometry
Provedor de dados: 77
Autores: Neri,Letícia Oliveira; de Amorim,Milena Menezes; Campos,Stella Andrade Rodrigues; Sanada,Luciana Sayuri; Fazan,Valéria Paula Sassoli.
Although numerous studies investigate sensory recovery of the hind paw of the rat after nerve damage, still no comprehensive overview of its normal innervation is present in the literature. We investigated the morphometry of myelinated fibers in the sural and saphenous nerves and analyzed their size distributions in young rats. Six 30-day-old female Wistar rats were perfused with 2.5% glutaraldehyde and their right and left sural and saphenous nerves were prepared for light microscopy and morphometry. Morphometric data were compared between segments (proximal versus distal) and sides (right versus left) for the same nerves. Also, segments from right or left sides were compared between nerves (sural versus saphenous). Both, the sural and saphenous nerves,...

Entrapment of the Sural Nerve on Gastrocnemius Muscle: Histological Analysis
Provedor de dados: 77
Autores: De-Paula,Rafael C; Felix,Bruno; Bezerra,Ewerton C; Rodrigues,Mauro R; Fernandes,Rodrigo M. P; Babinski,Marcio A.
Anatomical variations in the formation of the sural nerve are common, although the topographical localization of this nerve is constant. In this report, we describe the histological analysis of anomalous course of the medial sural cutaneous nerve which descended through the gastrocnemius via a tunnel formed within the muscle and fascia. This anatomical curiosity are clinically important when evaluating sensory axonal loss in distal axonal neuropathies since sural nerve mononeuropathy is less likely to occur.

Anatomy of the Sural Nerve Related to Calcaneal Tendon, Intermalleolar Line and Small Saphenous Vein
Provedor de dados: 77
Autores: Dangintawat,Pimpimol; Huanmanop,Thanasil; Agthong,Sithiporn; Chentanez,Vilai.
Sural nerve (SN) courses from the posterior aspect of leg to the lateral side of ankle and foot. Anatomy of the SN is of clinical importance due to its involvement in nerve biopsy, nerve graft harvesting including injuries during calcaneal tendon repair. Despite substantial knowledge in the literature, more easily located landmarks and data regarding the symmetry are still needed. Ninety-eight lower extremities from 31 males and 18 females were dissected in this study. The SN originated from the union between the medial and lateral sural cutaneous nerves in 52.0 % of the legs. The distance from the union point to the intermalleolar line (IML) was 16.3±8.4 (SD) cm. The ratio of this distance to the fibular length (apex of head to lateral malleolus or LM)...

Early myelin breakdown following sural nerve crush: a freeze-fracture study
Provedor de dados: 56
Autores: Martinez,A.M.B.; Canavarro,S.
In this study we describe the early changes of the myelin sheath following surgical nerve crush. We used the freeze-fracture technique to better evaluate myelin alterations during an early stage of Wallerian degeneration. Rat sural nerves were experimentally crushed and animals were sacrificed by transcardiac perfusion 30 h after surgery. Segments of the nerves were processed for routine transmission electron microscopy and freeze-fracture techniques. Our results show that 30 h after the lesion there was asynchrony in the pattern of Wallerian degeneration, with different nerve fibers exhibiting variable degrees of axon disruption. This was observed by both techniques. Careful examination of several replicas revealed early changes in myelin membranes...
