Anatomy mnemonics


As a medical student, Today I am happy to share all these medical anatomy medical mnemonics. These are collected from various offline and online sources including textbooks. If you know any other anatomy mnemonics please share via comments.

Hope you guy's will like this mnemonics collections.


 List of human anatomy mnemonics:

Afferent vs efferent:
Afferent connection arrives and an efferent connection exits.


Anterior leg muscles:
"The Hospitals Are Not Dirty Places"
  • Tibialis anterior

  • Duodenum
  • Jejunum
  • Ileum
  • Appendix
  • Colon

  • Rectum

Carotid sheath contents:

  • I See (I.C.) = Internal Carotid artery
  • 10 = CN 10 (Vagus nerve)
  • CC = Common Carotid artery
  • IV = Internal Jugular Vein

Cavernous sinus contents:
O TOM CAT:
O TOM are lateral wall components, in order from superior to inferior.
CA are the components within the sinus, from medial to lateral. CA ends at the level of T from O TOM.
  • Occulomotor nerve (III)
  • Trochlear nerve (IV)
  • Ophthalmic nerve (V1)
  • Maxillary nerve (V2)
  • Carotid artery
  • Abducent nerve (VI)
  • T: When written, connects to the T of OTOM

Coeliac trunk: branches:
Left Hand Side (LHS):
  • Left gastric artery
  • Hepatic artery
  • Splenic artery

Vertebral column:

  • Cervical (atlas, axis)
  • thoracic
  • lumbar
  • sacral
  • coccygeal

Tributaries of the Inferior vena cava:
"I Like TRise SHigh"
  • Iliac vein (common)
  • Lumbar vein
  • Testicular vein
  • Renal vein
  • Suprarenal vein
  • Hepatic vein

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.


Subclavian artery:
The branches of the subclavian artery can be remembered using VITamin C and D.


Posterior mediastinum:
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.

Superior orbital fissure:
Standing room only can be used to remember that:
  • V1 passes through the superior orbital fissure
  • V2 through the foramen rotundum
  • V3 through the foramen ovale.

Foramen magnum:
Contents of the foramen magnum: VAMPS-ATM
  • 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 dense
  • Tectorial membrane
  • Medulla oblongata.

Cerebellum:
Deep cerebellar nuclei and their positions relative to the midline: "Fat Guys Eat Donuts," where each letter indicates the medial to lateral location in the cerebellar white matter

Pes anserinus:
A mnemonic to remember the muscles that contribute tendons to the pes anserinus and the innervations of these muscles is SGT FOT (sergeant FOT)
Notice the order of the muscles (S, G, T) follows the order of the innervating nerves which correspond to those muscles (F, O, T).

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 nodeslocated 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 (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.

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," and for the initial letters "OOOTTAFVGVAH" is "Oh, oh, oh, to touch and feel very good velvet ... ah, heaven." 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 MBrother Says Benevolent Bride Matters More". There are a very large number of additional mnemonics.
  • For the five branches of the facial nerve there are: Two Zebras Bit My Cookie or To Zanzibar By MotorCar.


Endocrine glands:
The major glands of the endocrine system, excluding ovaries and testes: "T-A-P." (T2, A3, P4)
  • Thymus
  • Thyroid
  • Anterior pituitary
  • Adrenal cortex
  • Adrenal medulla
  • Posterior pituitary
  • Parathyroid gland
  • Pancreas
  • Pineal

Extraocular muscles:
A good mnemonic to remember which muscles are innervated by what nerve is to paraphrase it as a molecular equation: LR6SO4R3.
  • Lateral Rectus - Cranial Nerve VI
  • Superior Oblique - Cranial Nerve IV
  • the Rest of the muscles - Cranial Nerve III
Another way to remember which nerves innervate which muscles is to understand the meaning behind all the Latin words.
  • The fourth cranial nerve, the trochlear, is so named because the muscle it innervates, the superior oblique, runs through a little fascial pulley that changes its direction of pull (the trochlea of superior oblique). This pulley exists in the superiomedial corner of each orbit, and "trochl-" is Latin for "pulley."
  • The sixth cranial nerve, the abducens, is so named because it controls the lateral rectus, which abducts the eye (rotates it laterally) upon contraction.
  • The third cranial nerve, the oculomotor, is so named because it is in charge of the movement (motor) of the eye (oculo-). It controls all the other muscles.
