splanchnic nerve, lesser splanchnic nerve, least splanchnic nerve) Lymphatics The contents of posterior mediastinum can be remembered using the mnemonic, "DATES" Descending aorta Azygous vein and hemiazygos vein Thoracic duct Esophagus Sympathetic trunk/ganglia. Foramen magnum Contents of the foramen magnum: VAMPS-AT-SD or VAMPires Sing AT SD card Vertebral arteries Anterior spinal artery Meninges associated with the spinal cord Posterior spinal arteries Spinal roots of the accessory nerve (CN XI) Apical ligament of the dens Tectorial membrane Spinal cord Dural veins (Dural venous sinuses) Contents of the foramen magnum: VAMPS-ATM or VAMPires Sing AT Midnight Vertebral arteries Anterior spinal artery Meningeal branches of the cervical nerves Posterior spinal arteries Spinal part of the accessory nerve Alar and apical ligaments of the dens Tectorial membrane Medulla oblongata Greater sciatic foramen Structures passing through greater sciatic foramen below piriformis (S.N.I.P. N.I.P.) sciatic nerve nerve to obturator internus internal pudendal vessel pudendal nerve nerve to quadratus femoris inferior gluteal vessels posterior cutaneous nerve of thigh Lesser sciatic foramen Structures passing through lesser sciatic foramen: (P.I.N.T.) pudendal nerve internal pudendal vessels nerve to obturator internus tendon of obturator internus Tarsal tunnel a mnemonic to remember the contents of the Tarsal tunnel from anterior to posterior is "Tom, Dick and Harry". or alternatively "Tom, Dick (and very nervous) Harry" if the artery, vein, and nerve are included. Femoral triangle The femoral triangle is shaped like the sail of a sailing ship and hence its boundaries can be remembered using the mnemonic, "SAIL": Sartorius Adductor longus Inguinal Ligament. The order of structures in the femoral triangle is important in the embalming of bodies, as the femoral artery is often exposed and used to pump embalming fluids into the body. The order of this neurovascular bundle can be remembered using the mnemonic, "NAVY": Nerve Artery Vein Y -fronts (the British term of a style of men's underwear with a "Y" shaped front that acts as a fly). The "Y" is midline (corresponding with the penis) and the mnemonic always reads from lateral to medial (in other words, the Femoral Nerve is always lateral). An alternate to this mnemonic is "NAVEL" for Nerve, Artery, Vein, Empty Space and Lymph, to include the deep inguinal lymph nodes located medial to the Femoral vein. Popliteal fossa A useful mnemonic to remember popliteal fossa anatomy (medial-to-lateral arrangement) is: Serve And Volley Next Ball. S: semimembranosus and semitendinosus (superior medial border) A: artery
