The Spinal Nerves That Constitute the Plexus Lumbosacrales of Porcupines (Hystrix Cristata)
Original Paper Veterinarni Medicina, 54, 2009 (4): 194–197 The spinal nerves that constitute the plexus lumbosacrales of porcupines (Hystrix cristata) A. Aydin, G. Dinc, S. Yilmaz Faculty of Veterinary Medicine, Firat University, Elazig, Turkey ABSTRACT: In this study, the spinal nerves that constitute the plexus lumbosacrales of porcupines (Hystrix cristata) were investigated. Four porcupines (two males and two females) were used in this work. Animals were appropriately dissected and the spinal nerves that constitute the plexus lumbosacrales were examined. It was found that the plexus lumbosacrales of the porcupines was formed by whole rami ventralis of L1, L2, L3, L4, S1 and a fine branch from T15 and S2. The rami ventralis of T15 and S2 were divided into two branches. The caudal branch of T15 and cranial branch of S2 contributed to the plexus lumbosacrales. At the last part of the plexus lumbosacrales, a thick branch was formed by contributions from the whole of L4 and S1, and a branch from each of L3 and S2. This root gives rise to the nerve branches which are disseminated to the posterior legs (caudal glu- teal nerve, caudal cutaneous femoral nerve, ischiadic nerve). Thus, the origins of spinal nerves that constitute the plexus lumbosacrales of porcupine differ from rodantia and other mammals.

Study of Anatomical Pattern of Lumbar Plexus in Human (Cadaveric Study)
54 Az. J. Pharm Sci. Vol. 54, September, 2016. STUDY OF ANATOMICAL PATTERN OF LUMBAR PLEXUS IN HUMAN (CADAVERIC STUDY) BY Prof. Gamal S Desouki, prof. Maged S Alansary,dr Ahmed K Elbana and Mohammad H Mandor FROM Professor Anatomy and Embryology Faculty of Medicine - Al-Azhar University professor of anesthesia Faculty of Medicine - Al-Azhar University Anatomy and Embryology Faculty of Medicine - Al-Azhar University Department of Anatomy and Embryology Faculty of Medicine of Al-Azhar University, Cairo Abstract The lumbar plexus is situated within the substance of the posterior part of psoas major muscle. It is formed by the ventral rami of the frist three nerves and greater part of the fourth lumbar nerve with or without a contribution from the ventral ramus of last thoracic nerve. The pattern of formation of lumbar plexus is altered if the plexus is prefixed (if the third lumbar is the lowest nerve which enters the lumbar plexus) or postfixed (if there is contribution from the 5th lumbar nerve). The branches of the lumbar plexus may be injured during lumbar plexus block and certain surgical procedures, particularly in the lower abdominal region (appendectomy, inguinal hernia repair, iliac crest bone graft harvesting and gynecologic procedures through transverse incisions). Thus, a better knowledge of the regional anatomy and its variations is essential for preventing the lesions of the branches of the lumbar plexus. Key Words: Anatomical variations, Lumbar plexus. Introduction The lumbar plexus formed by the ventral rami of the upper three nerves and most of the fourth lumbar nerve with or without a contribution from the ventral ramous of last thoracic nerve.

Cutaneous Nerve Stimulation and Motoneuronal Excitability. II: Evidence for Non-Segmental Influences
Journal of Neurology, Neurosurgery, and Psychiatry 1984;47: 190-196 Cutaneous nerve stimulation and motoneuronal excitability. II: evidence for non-segmental influences PJ DELWAIDE, P CRENNA* From the Section ofNeurology and Clinical Neurophysiology University of Liege, Liege, Belgium SUMMARY After stimulation of a sensory nerve, even distant motor nuclei undergo excitability changes which are evidenced by recovery curves. In all, two unequal peaks of facilitation can be identified. They appear when a given motor nucleus is tested after stimulation of various sensory nerves or when the same stimulation (of the sural nerve) is studied in various motor nuclei. The first facilitation is seen earlier in the masseter, then in the arm muscles and finally in lower limb muscles. The existence of a supraspinal centre activated by low threshold exteroceptive afferents and facilitating motor nuclei in a rostro-caudal sequence is postulated to account for certain features of the first and second peaks of facilitation. In an earlier publication, we' described excitability sural nerve stimulation on various motor nuclei changes in soleus and tibialis anterior motoneurons located along the length of the neuraxis: soleus, following stimulation of the sural nerve at different quadriceps, short biceps, biceps brachii and masse- intensities.

Toreih, MD,1 Asser A. Sallam, MD, PhD,1 Cherif M. Ibrahim, MD,2 Ahmed I. Maaty, MD,3 and Mohsen M. Hassan4 Departments of 1Orthopedic Surgery and Trauma and 3Physical Medicine, Rheumatology, and Rehabilitation, Suez Canal University Hospitals; 2Department of Anatomy, Suez Canal University; and 4Department of Surgery, Anesthesiology, and Radiology, Faculty of Veterinary Medicine, Suez Canal University, Ismailia, Egypt OBJECTIVE Spinal cord injury (SCI) has been investigated in various animal studies. One promising therapeutic ap- proach involves the transfer of peripheral nerves originating above the level of injury into those originating below the level of injury. The purpose of the present study was to evaluate the feasibility of nerve transfers for reinnervation of lower limbs in patients suffering SCI to restore some hip and knee functions, enabling them to independently stand or even step forward with assistive devices and thus improve their quality of life. METHODS The feasibility of transferring intercostal to gluteal nerves and the ilioinguinal and iliohypogastric nerves to femoral nerves was assessed in 5 cadavers. Then, lumbar cord hemitransection was performed below L1 in 20 dogs, followed by transfer of the 10th, 11th, and 12th intercostal and subcostal nerves to gluteal nerves and the ilioinguinal and iliohypogastric nerves to the femoral nerve in only 10 dogs (NT group). At 6 months, clinical and electrophysiological evaluations of the recipient nerves and their motor targets were performed.

19408-Unusual-Origin-Of-The-Anterior-Scrotal-Nerve-A-Case-Report.Pdf
Open Access Case Report DOI: 10.7759/cureus.4557 Unusual Origin of the Anterior Scrotal Nerve: A Case Report Karishma Mehta 1 , Joe Iwanaga 2 , R. Shane Tubbs 3 1. Clinical Anatomy, Seattle Science Foundation, Seattle, USA 2. Medical Education and Simulation, Seattle Science Foundation, Seattle, USA 3. Neurosurgery, Seattle Science Foundation, Seattle, USA Corresponding author: Joe Iwanaga, [email protected] Abstract The anterior scrotal nerve is a cutaneous nerve that branches from the ilioinguinal nerve after it leaves the superficial inguinal ring. However, we identified a cadaveric specimen with an anterior scrotal nerve arising from both the femoral and ilioinguinal nerves. This anatomic variation should be considered with anesthetic blockade of this region or during surgical procedures nearby. Categories: Other Keywords: scrotum, femoral nerve, ilioinguinal nerve, anatomy, cadaver Introduction The anterior scrotal nerve provides cutaneous innervation to a portion of the penis and the upper scrotum in males. It arises from the ilioinguinal nerve after the aforementioned nerve passes through the superficial inguinal ring [1]. Both the ilioinguinal and femoral nerves originate from the lumbar plexus via ventral rami of L1 and L2-4, respectively. Normally, the femoral nerve gives rise to two cutaneous branches, anterior femoral nerves, and the saphenous nerve [2-3]. Herein, we report a case in which the anterior scrotal nerve arose from both the ilioinguinal and femoral nerves. Case Presentation During routine dissection of the thigh, a variant anterior scrotal branch was found in an African-American fresh-frozen male cadaver whose age at death was 79-years-old. The anterior division of the femoral nerve gave rise to two cutaneous nerves, the medial femoral cutaneous nerve of the thigh (MFC) and the intermediate cutaneous nerve of the thigh (ICN).
