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.[8]

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.

  • A: artery (popliteal artery)
  • V: vein (popliteal vein)
  • N: nerve (tibial nerve)
  • B: biceps femoris (superior lateral border). The lateral and medial heads of gastrocnemius form the inferior border.[9]

Cranial nerves

There are many mnemonics for the names of the cranial nerves, e.g.

  • “OOOTTAFAGVSH” is “OLd OPen OCeans TROuble TRIbesmen ABout Fish VEnom Giving VArious ACute/SPlitting Headaches” (a mnemonic that gives enough letters to distinguish between nerves that start with the same letter), or “On old Olympus’s towering tops, a Finn and German viewed some hops,”[10] and for the initial letters “OOOTTAFVGVAH” is “Oh, oh, oh, to touch and feel very good velvet … ah, heaven.”[11] The differences between these depend on “acoustic” versus “vestibulocochlear” and “spinal-accessory” versus “accessory”.
  • A common example mnemonic for remembering which nerves are motor (M), sensory (S), or both (B), “Some Say Marry Money But My Brother Says Benevolent Bride Matters More”. There are a very large number of additional mnemonics.[12]
  • For the five branches of the facial nerve there are: Two Zebras Bit My Cookie or To Zanzibar By MotorCar

Diaphragm apertures: spinal levels

Many mnemonics are used for diaphragm apertures including:

Number of letters

  • Aortic hiatus = 12 letters = T12
  • Oesophagus = 10 letters = T10
  • Vena cava = 8 letters = T8[1]p.

I ate 10 eggs at 12

  • I = IVC
  • ate = T8
  • 10 = T10
  • Eggs = Esophagus
  • At = Aorta
  • 12 = T12

  • E – ELECTROLYTE balance

  • B – BLOOD Pressure control
  • E – making ERYTHROPOIETIN
  • D – Vitamin D metabolism

Lateral geniculate nucleus

A simple mnemonic for remembering this[clarify] is “See I? I see, I see,” with “see” representing the C in “contralateral,” and “I” representing the I in “ipsilateral.” Another is “Emily and Pete meet eye to eye” as in “M and P meet I to I,” or again, Magno and Parvo meet Ipsi to Ipsi.

Another way of remembering this[clarify] is 2+3=5, which is correct, so ipsilateral side, and 1+4 doesn’t equal 6, so contralateral.
