1 The superior gluteal nerve and the nerve to quadratus femoris/inferior gemellus share the same nerve roots (L4, L5 and S1).  Similarly, the inferior gluteal nerve and the nerve to obturator internus/superior gemellus also share the same nerve roots (L5, S1 and S2).
Inferior alveolar nerve block (abbreviated to IANB, and also termed inferior alveolar nerve anesthesia or inferior dental block) is a nerve block technique which induces anesthesia (numbness) in the areas of the mouth and face innervated by one of the inferior alveolar nerves which are paired on the left and right side.he inferior alveolar nerve is a branch of the mandibular nerve, the third division of the trigeminal nerve. This procedure attempts to anaesthetise the inferior alveolar nerve prior to it entering the mandibular foramen on the medial surface of the mandibular ramus.
