Location of the thoracic duct

• The duck is between two gooses (duck = thoracic duct)
• 2 gooses = azyGOUS and esophaGOUS

Length of parts of Duodenum

“Counting 1 to 4 but staggered”:

1st part: 2 inches
2nd part: 3 inches
3rd part: 4 inches
4th part: 1 inch

Diaphragm apertures:Vertebral levels

Aortic hiatus = 12 letters = T12
Oesophagus = 10 letters = T10
Vena cava = 8 letters = T8

Femoral triangle: arrangement of contents NAVEL
From lateral hip towards medial navel:
Nerve (directly behind sheath)
Artery (within sheath)
Vein (within sheath)
Empty space (between vein and lymph)
Lymphatics (with deep inguinal node)
Nerve/Artery/Vein are all called Femoral.

Aortic arch: major branch order

“Know your ABC’S“:
Aortic arch gives rise to:
Brachiocephalic trunk
left Common Carotid
left Subclavian

Scalp layers SCALP:
From superficial to deep:
Skin
Connective tissue
Aponeurosis
Loose areolar tissue
Pericranium

Kidney hilums at transpyloric plane [L1]

L-1 goes through hilum of only 1 kidney, and it’s the Left one.

Thoracic duct: relation to azygous vein and esophagus

“The duck between 2 gooses“:
Thoracic duct (duck) is between 2 gooses, azygous and esophagus.

Thoracic duct: which half of upper body does it drain

Drains whole of lower body+Left of upper body

Remember Lymph from the Lower body and  Left of the upper body.

Parts of papez circuit

Mnemonic -MATCH

Mamillary body

Anterior Thalamic nucleus

Cingulate gyrus

Hippocampus

 Structures passing through foramen ovale of skull

Mnemonic- OVALE

O – Otic ganglion (Does not pass through,lies inferior to foramen ovale)
V – V3 cranial nerve
A – Accessory meningeal artery
L – Lesser petrosal nerve
E – Emissary vein

Carotid sheath contents “I See 10 CC‘s in the IV“:
I See (I.C.) = Internal Carotid artery
10 = CN 10 (Vagus nerve)
CC = Common Carotid artery
IV = Internal Jugular Vein

Branches of the coeliac arterial trunk

Mnemonic -LHS(Left Hand Side)

Left Gastric artery

Hepatic artery

Splenic artery

The nerves supplying the scalp

Mnemonic -GLASS

G – Greater occipital/ Greater auricular
L – Lesser occipital
A – Auriculotemporal
S – Supratrochlear
S – Supraorbital

Lumbar plexus roots “2 from 1, 2 from 2, 2 from 3“:
2 nerves from 1 root: Ilioinguinal (L1), Iliohypogastric (L1).
2 nerves from 2 roots: Genitofemoral (L1,L2), Lateral Femoral (L2,L3).
2 nerves from 3 roots: Obturator (L2,L3,L4), Femoral (L2,L3,L4).

The layers of scrotum from superficial to deep

Mnemonic-Some Dirty Englishmen Called It Testis

S – Skin
D – Dartos
E – External spermatic fascia
C- Cremasteric fascia
I – Internal spermatic fascia
T -Testis

The arrangement of carpal bones

Starting from distal row and counting from medial to lateral and continuing to upper row and counting it from lateral to medial.

 Contents of broad ligament

Mnemonic -BROAD

B – Bundle (ovarian neurovascular bundle)
R – Round ligament
O – Ovarian ligament
A – Artefacts (vestigial structures)
D – Duct (oviduct)

Inversion vs. eversion muscles in leg

Second letter rule for inversion/eversion:
· Eversion muscles:
pErineus longus
pErineus brevis
pErineus terius
· Inversion muscles:
tIbialis anterior
tIbialis posterior

Spermatic cord contents “3 arteries, 3 nerves, 3 other things”:
3 arteries: testicular artery, aretry to ductus deferens, cremasteric aretry.
3 nerves: genital branch of the genitofemoral, cremasteric, autonomic nerves.
3 other things: ductus deferens, pampiniform plexus, lymphatics.

Interossei muscles: actions of dorsal vs. palmar in hand “PAd and DAb“:
The Palmar Adduct and the Dorsal Abduct.
