Detailed explanation-1: -All the nerves of the sacral plexus arise from three nerve roots EXCEPT the sciatic nerve, which has five nerve roots. The superior gluteal nerveand the nerve to quadratus femoris/inferior gemellus share the same nerve roots (L4, L5 and S1).
Detailed explanation-2: -These branches include the iliohypogastric, ilioinguinal, genitofemoral, lateral femoral cutaneous, femoral and obturator nerves.
Detailed explanation-3: -The femoral nerve is the largest nerve of the lumbar plexus. It forms from the dorsal divisions of the L2-L4 ventral rami. [1] It has a role in motor and sensory processing in the lower limbs. As a result, it controls the major hip flexor muscles, as well as knee extension muscles.
Detailed explanation-4: -Sciatic Nerve (L4-S3) Pudendal Nerve (ventral divisions of S2-S4) Superior Gluteal Nerve (dorsal divisions of L4-S1) Inferior Gluteal Nerve (dorsal divisions of L5-S2) Nerve to Obturator Internus (ventral divisions of L5-S2) Nerve to Quadratus Femoris.
