Bronchi: which one is more vertical

"Inhale a bite, goes down the right":

Inhaled objects more likely to lodge in right bronchus, since it is the one that is more vertical.

Hip posterior dislocation: most likely arrangement for one

"Hitting the brake pedal before the accident":

You are sitting, so hip is flexed, and adducted and medially rotated so can move your foot away from the gas pedal over to the brake pedal.

 Note: car accidents are most likely cause of posterior dislocation because in this position.

Buttock quadrant safest for needle insertion

� See diagram.

Therefore, cuboid has to contact 2 of the 5.

Green organ in body is gallbladder, so Murphy's point is the gall bladder.

Anteflexed vs. anteverted: what bodypart each describes

"Anteflexed and Anteverted both bend toward Anterior".

� The "V" words go together: Verted is for the cerVix (therefore flexed must be uterus).

Foramen spinosum: location on base of skull

Foramen spinosum is adjacent to the spine of sphenoid.

Pterygoid muscles: function of lateral vs. medial

"Look at how your jaw ends up when saying first syllable of 'Lateral' or 'Medial' ":

Leino- definition

"Leino" rhymes with "spleen-o":

Therefore leino- means something to do with the spleen.

Kidney hilums at transpyloric plane [L1]

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

Lung lobe numbers: right vs. left

 

Tricuspid heart valve and tri-lobed lung both on the right side.

Bicuspid and bi-lobed lung both on the left side.

Vertebrae: recognizing a thoracic from lumbar

Examine vertebral body shape:

Thoracic is heart-shaped body since your heart is in your thorax.

Lumbar is kidney-bean shaped since kidneys are in lumbar area.

Median nerve: recognizing it in an opened axilla

The Median nerve is the Middle of a giant capital "M" formed by the musculocutaneous and ulnar nerves.

Think "peripheral nerves":

The ulnar nerve is "ulnar" to the ulnar artery.

Radial nerve is "radial" to the radial artery.

Dermatome C6 location

Stick arm out like crucifixion stance. Curl your thumb and forefinger into an "OK" symbol while keeping your other fingers straight.

Your hand should now look like a 6 shape.

Answer: it’s Lymph from the Left of the upper body.

Soleus vs. gastrocnemius muscle function

"Stand on your Soles. Explosive gas":

You stand on soles of your shoes, so Soleus is for posture.

Gasoline is explosive, so Gastrocnemius is for explosive movement.

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

Liver inferior markings showing right/left lobe vs. vascular divisions

There's a Hepatic "H" on inferior of liver. One vertical stick of the H is the dividing line for anatomical right/left lobe and the other vertical stick is the divider for vascular halves. Stick that divides the liver into vascular halves is the one with vena cava impression (since vena cava carries blood, it's fortunate that it's the divider for blood halves).

Pleura surface markings

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

Rib2: sharp angle inferiorly

Rib4: the left pleura does a lateral shift to accommodate heart

Rib6: both diverge laterally

Rib8: midclavicular line

Rib10: midaxillary line

Rib12: the back

� See diagram.
