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).
Sensory innervation of the forehead and anterior scalp is supplied by the supraorbital and supratrochlear nerves, being branches of the ophthalmic division of the trigeminal nerve. The supraorbital nerve and vessels emerge from the supraorbital foramen or notch and continue superiorly.he usual trajectory of the nerve is from a point 5 mm below the tragus to a point 15 mm above the lateral extremity of the brow. Over the zygomatic arch, it is situated halfway between the lateral canthus and the inferior helix. This places it about 2.5 cm lateral to the lateral canthus.
