 | | The inusculo cutaneous nerve supplies the peroneus longus and brevis muscles, and the rest of the skin of the dorsum, of the foot, and lower part of the leg, while the skin of the upper part of the dorsum of the leg, below the knee, is supplied by the external popliteal before its division. | | | The spinal nerves are those which arise from each side of the spinal cord and are distributed to the trunk and limbs, though some of the upper ones supply the lower parts of the head and face. | | | The external eutaneous nerve (L.2, 3) supplies the skin of the outer side of the thigh, while the anterior crural (L.2, 3, 4) innervates the muscles on the front of the thigh, the skin on the front and inner From A.

| | Biopsy of the motor nerve of the gracilis muscle is indicated in neuromuscular diseases that affect the thigh adductor musculature. | | | In 1991, biopsy of the motor nerve to the gracilis muscle was developed to allow histopathological analysis in these conditions. | | | The purpose of this paper is to describe the anatomy, indications, contraindications, technique, surgical results, and complications of motor nerve biopsy of the gracilis muscle. |

| | The use of intraoperative nerve conduction studies is an important improvement in the surgical treatment of peripheral nerve injuries that are in continuity [13,14]. | | | Nerve conduction studies (NCS) and needle electromyography (EMG) are complimentary techniques that are together often termed EMG, although strictly speaking this refers only to the needle part of the studies. | | | This motor axon and the muscle fibers it supplies is considered the motor unit, an important structural unit in EMG studies and in understanding recovery from nerve injury. |

| | The peripheral spinal nerve is formed by the confluence of the dorsal and the ventral spinal roots near the spinal column. | | | It should be obvious that the techniques of peripheral nerve testing are beneficial mainly in the evaluation of cases of suspected peripheral nerve or muscle disease. | | | For both the forelimbs and hindlimbs the spinal nerves generally participate in the formation of a nerve plexus from which the nominate peripheral nerves emerge. |

| | The term peripheral nerve is often used to indicate the portion of a spinal nerve distal to the root and plexus. | | | The peripheral nervous system consists of cranial and spinal nerves from their points of exit from the CNS to their termination in peripheral structures. | | | Each spinal nerve (in 31 pairs) emerges from a segment of the spinal cord as an anterior (ventral) motor root and a posterior (dorsal) sensory root. |

| | For the lumbar plexus, the L2 to L4 nerve roots can be stimulated by using a needle electrode inserted 2-3 cm laterally to the L4 spinous process and the response recorded from the quadriceps. | | | For the sacral plexus, the roots are stimulated with a needle electrode inserted medially and just caudally to the posterior superior iliac spine and the response recorded from the abductor hallucis. | | | It is designed to familiarize the reader with the basic aspects of nerve conduction studies and needle examinations and can serve as a guide to the test, a preparation for the EMG rotation, or as a simple means for better understanding of the indications, preparations, interpretation and performance of EMG Nerve and Conduction studies |

| | Amplitude parameters are dependent on both the needle position in relation to the nerve, and the distance between the stimulation and recording. | | | In healthy subjects, the mean value of the AMPLDECAY is 4.5-6.2% in the ulnar nerve [27;35], and 5.6-7.7% in the median nerve [11]. | | | The pathophysiological principles regarding sensory nerves are the same as those discussed for motor nerves. |

| | Nerve conduction response from the FDI with stimulation of the ulnar nerve is absent. | | | This supports the hypothesis of a distal lesion of the ulnar nerve, likely affecting the deep ulnar branch in the hand. | | | Needle EMG is designed to evaluate the muscles found to be weak on physical examination (FDI), but also to compare with muscles supplied by other branches of the same peripheral nerve (e.g. |

| | Overall, sensory nerve nuclei tend to be located in the lateral brainstem, while motor nuclei tend to be located medially. | | | Hence the IVth nerve innervates the superior oblique. | | | The XIth nerve actually originates in the cervical spinal cord. |

| | The motor component innervates skeletal muscles, such as the pharyngeal and laryngeal muscles, the nerves for which are located in the nucleus ambiguous (SVE). | | | They are classified on the basis of comparative anatomy and embryological studies where nerve fibers were traced from their point of origin in the periphery to their termination within the central nervous system. | | | There are some pain, temperature and proprioception fibers which return via the fibers to the nucleus ambiguous, leading to more confusion about localizing pain in the head and neck. |
