Useful Mnemonics from Anatomy

Anatomy Respiratory System Mnemonics: Mnemonics are excellent method for memorizing Anatomy. Anatomy may not always be easy to understands or remember, so here are few mnemonics which shall help Medical students.

Phases of Development of lungs:

“Every Premature Child Takes Air”

E = Embryonic (4-5 weeks)
P = Pseudoglandular (5-16 weeks)
C = Canalicular (16-26 weeks)
T = Terminal sac (26 weeks to 8 months)
A = Alveolar (8 months to birth)

Nerve supply of diaphragm:

C three,four and Five, keeps diaphragm alive

Phrenic nerve (C3-5) supplies diaphragm. Irritation of diaphragm may cause referred pain on shoulder because phrenic nerve and supraclavicular nerve have same root value i.e. C3-5.

Opening of Diaphragm:

Voice of America (VOA 8,10,12)

Venacaval opening lies in the central tendon of diaphragm at the level of T8
Oesophageal opening lies in the muscular part of diaphragm at the level of T10
Aortic opening lies at the lower border of T12

Components of median nasal septum (medial wall of nasal cavity):

VPN (virtual private network) of RS 100

V = Vomer
P = Perpendicular plate of ethmoid
N = Nasal spine of frontal bone; Nasal crests of nasal, palatine and maxillary bone
R = Rostrum of sphenoid
S = Septal cartilage, Septal process of inferior nasal cartilage

Bronchopulmonary segments of Lung:

A PALM Seed MakeS Another Little Palm”

From superior to inferior:
Apical
Posterior
Anterior
Lateral
Medial
Superior
Medial basal
Anterior basal
Lateral basal
Posterior basal

Parts of Larynx (Voicebox) in sagittal section:

3 Vs

Vestibular fold
Ventricle (Sinus)
Vocal fold

Pleura surface markings:

All the even ribs, in order: 2,4,6,8,10,12 show its route

Rib 2: sharp angle inferiorly
Rib 4: the left pleura does a lateral shift to accommodate heart (cardiac notch)
Rib 6: both diverge laterally
Rib 8: midclavicular line
Rib 10: midaxillary line
Rib 12: the back

Contents of Superior Mediastinum:

PVT Left BATTLE

P = Phrenic nerve
V = Vagus nerve
T = Thoracic duct
Left = Left recurrent laryngeal nerve
B = Brachiocephalic veins
A = Arch of aorta and its 3 branches
T = Thymus
T = Trachea
L = Lymph nodes
E = Esophagus

The 3 branches of Arch of Aorta

ABCs of Aortic Arch

A = Aortic arch
B = Brachiocephalic trunk
C = Left common carodtid artery
S = Left subclavian artery

Contents of posterior mediastinum:

4 birds:

esophaGOOSE (esophagus)
vaGOOSE nerve (vagus)
azyGOOSE vein (azygos)
thoracic DUCK (duct)
