Study Notes

Lumbar Plexus

Mnemonic for lumbar plexus root values: "I Got Lunch On Friday"
Ilioinguinal and Iliohypogastric nerves arise from L1
Genitofemoral nerve stems from L1 and L2
Lateral femoral cutaneous nerve is derived from L2 and L3
Obturator and Femoral nerves originate from L2, L3, and L4

Sacral Plexus Branches

Nerve to Piriformis comes from S1 and S2
Perforating cutaneous nerve serves the medial buttock, branching from S2 and S3
Posterior femoral cutaneous nerve supplies the buttock and uppermost medial and posterior thigh areas, originating from S1, S2, and S3
Pudendal nerve, essential for pelvic floor function, arises from S2, S3, and S4, exiting the pelvis via the greater sciatic foramen and re-entering through the lesser sciatic foramen into the pudendal canal

Branches of Pudendal Nerve

Mnemonic for Pudendal nerve branches: "PID" (Pelvic Inflammatory Disease relates to Pudendal neuralgia)
Perineal nerve is a branch of the Pudendal nerve
Inferior rectal nerve supplies the lower rectum, also a branch of the Pudendal nerve
Dorsal nerve serves the penis or clitoris, completing the Pudendal nerve branches
