Hey guys welcome back to the channel if
you're new here I'm Sebastian a medical
student from Australia
and today I'm joined by my friend Declan
hey and my girlfriend Deborah.
Declan and I will be facing off in a
one-to-one anatomy quiz battle
and Deborah over here has kindly
prepared 30 questions for us to answer
and we'll get one point for every
correct answer. At the end of the game
the winner will make a drink for the
other person which will be made up of
ingredients from the kitchen
so follow along and feel free to answer
the questions with us.
[Music]
Question 1: What three bones make up the innominate?
the innominate so this this is the hip
bone
all right okay
so you have the pubis yes
you have the ischeum and you have the
ilium yes
correct I actually knew that I didn't
know what the innominate was
Question number 2: What is the name of the heel bone?
Calcaneus. Correct. I was thinking of the navum?
Is that that's one of the ones here no
you have the navicular bone navicular
yeah and then you have the cuneiform
I was just trying to make sure that I got it right
These are hard bro. It's been 3 weeks since the end of med school for us
so we're a bit rusty but bear with us
Next question!
Damage to which muscles can produce a positive trendelenburg sign?
Declan. Gluteus medius and gluteus minimus.
Next question! What nerve innervates the posterior compartment of the leg?
Declan. Oh bro, this is a 50-50. Ah, superficial perineal nerve. Wrong.
Sciatic nerve.
Also wrong. It is the tibial nerve.
I thought tibia was like anterior that's
the peroneal wait the sciatic nerve?
Sciatic is the posterior of the thigh. Not the
leg bro. Oh, the leg!
I think seb's minus a point for that one.
What do you mean bro? And you buzzed in first.
Next question! Which nerve innervates the medial compartment of the thigh?
Obturator nerve. Yes, correct!
I was like it's femoral, then it's not femoral - it's the one starting with 'O'.
Question 6: What are the borders of the femoral triangle?
So the medial border of the femoral
triangle is adductor longus,
lateral is sartorius, (correct!)
and the superior border is the inguinal
ligament. Very good!
Yeah I was hoping you wouldn't get
sartorius
I couldn't remember what the medial border was.
Next question!
5 muscles insert into the greater trochanter, identify 3 of these.
Sebastian! Vastus lateralis.
I couldn't even get one of them.
Gluteus maximus.
Wrong! Really? Wait! What were the options?
Okay.
5 muscles. 5 muscles - so you have the
external rotators of the hips
that includes the gluteus medius the
gluteus minimus
yeah the piriformis yep yeah the
obturator externus
and the obturator internus
What is the most commonly fractured bone following a fall on outstretched hand (FOOSH)?
Declan! Radius. Wrong. Sebastian! Scaphoid.
Correct! Yeah one of my mates fell over
and fractured the scaphoid all right
we thought we thought it was dislocated
like in here yeah so we're going to try
and put it back in and then we're like
no let's go to the hospital that's why
you don't try and
put bones back in if you're not
medically trained.
Damage to which nerve roots results in
Erb's palsy?
Otherwise known as waiter's tip. Declan.
C8-T1? Wrong.
T5-T6? Also wrong. The other part of the
brachial plexus
C5-C6.
Damage to what nerve results in the classical saying '5,6,7 wings to heaven'?
(Deb) Declan! (Declan) Long thoracic? (Deb) Correct! (Seb) Ohhhh, yeah I knew it then you pinged it.
(Seb) Cause it's scapular winging. (Declan) The only one I know is '3,4,5 keep the diaphragm alive'.
Next question! Which nerve travels between flexor digitorum profundus and flexor digitorum superficialis?
(Seb) Ulnar nerve! (Deb) Wrong. (Declan) Median nerve? (Deb) Correct!
Final question in upper limb MSK.
What are the contents of the cubital fossa?
(Deb) Sebastian. (Seb) Flexor pollicis longus. (Deb) Wrong.
Ohh, it's the other way round! Nooo.
I'm pretty sure it's abductor pollicis longus.
Wrong, the question was what are the contents
of the cubital fossa yeah this one
that's the anatomical snuff box oh wait
what's the cubital fossa
oh is that oh it's here oh the brachial
artery
welcome back guys to our anatomy game
show
for which we cannot identify the
snuffbox versus the cubital fossa
all right f's in the chat yeah that's
bad
Does water appear white or dark on T2 weighted MRI?
White! Correct. That's an easy one now I
didn't I didn't think quick enough yeah
yeah next question through which foramen
does CSF flow from the lateral
ventricles
into the 3rd ventricle
Declan. Foramen of Magendie?
Yes it's the Foramen of Monro or the
interventricular foramen yeah correct
Knew it started with 'M'.
In a lumbar puncture what space is accessed to withdrawal cerebrospinal fluid?
Subarachnoid space. Correct!
Lateral meduallary syndrome most commonly results from occlusion of which artery?
Declan. PICA. Correct.
What is PICA? Posterior inferior
cerebellar artery yeah you got it nice
yeah good job
all right which cranial nerve emerges
from the dorsal surface of the brainstem?
Sebastian! Trochlear nerve.
Which is what number?
Four. Dangit! We have a final question to
finish off the neuroanatomy section.
Lesion to which brain lobe can result in a contralateral homonymous lower quadrantanopia?
Declan. Parietal? Correct! Yes, good job!
Yeah you got it. Yeah, I had to use my Parietal lobe to think of that.
It was actually trying to figure out
what the words meant yeah yeah I
realized it was
like saying two loops yeah i was like
what's homonymous?
[Music]
Easy question to start off with all
right what are the three divisions of
the trigeminal nerve
So V3 mandibular, V2 maxillary and V1 ophthalmic.
Which muscle closes the eyes?
Declan. Obicularis oculi.
Next question! What are the 4 parasympathetic ganglia?
Declan. Otic, pterygopalatine 0:08:38.080,0:08:45.760 ciliary and
submandibular correct yes you got it
which was the one you couldn't remember?
Ciliary.
70% of epidural hematomas result from damage to which artery?
Middle meningeal.
I don't want to drink this. Me neither.
Ortner's syndrome refers to hoarseness due to nerve palsy caused by cardiovascular disease.
Specifically, which nerve is affected?
Recurrent laryngeal.
The left. Correct!
What is Ortner's sydnrome, I have nerver heard of it before
in my life!
It's a hoarseness yeah yeah I got that
from that that's that's where I got it
from
like yeah okay there you go you learn
something new every day alright
for the final question about head and
neck anatomy it's going to be a multiple
choice question
but if you know the answer feel free to
go ahead first.
The ansa cervicalis does not innervate which of the following structures: omohyoid, sternohyoid, thyrohyoid or sternothyroid?
(Deb) Declan. (Declan) Omohyoid. (Deb) Wrong.
It's up to you now. 1 in 3. Sternothyroid
Wrong. The answer is thyrohyoid!
What is the ansa cervicalis?
[Music]
Seb's better at moving this okay for
our first easy question
what are the four layers of the
gastrointestinal wall?
so mucosa submucosa muscularis externa
and adventitia or serosa depending where
you're at correct
damn easy one that was really easy
next question at what vertical level
does the aorta bifurcate into the common
iliac artery?
(Seb) L4! (Declan) Dangit!
What is the whipple procedure most commonly used to treat?
pancreatic adenocarcinoma generally
pancreatic cancer but yes pancreatic
cancer
yeah three more questions
Identify 3 structures that pass through the diaphragm at the level of T12.
I went in too early because okay hang on.
So you have the
aorta okay yeah yeah you keep going
and you have the thoracic duct
and you have the the nerves - phrenic nerve?
(Deb) Wrong! Sebastian? (Seb) So aorta, thoracic duct,
vagus nerve? (Deb) Wrong!
The vagus nerve is through T10 isn't it? It's with the oesophagus.
Next question! What does ERCP stand for?
I've got a mind blank right so
it's something retrograde
um keep going colangio i need to write
it out i need to write it down
stands for um endoscopic
retrograde uh cholangio pancreatography
correct yeah
damn dude we are currently on 11 for
Declan
and 12 for Sebastian I'm scared man
Final question: The ligamentum venosum is the remnant of which embryonic structure?
Umbilical vein! Correct!
i was thinking umbilical cord and i was
like it's not the umbilical cord it's
umbilical something
Alright guys so Declan put in his all, I got there in the end.
But to be honest, it just highlights how little we've remembered this year so definitely have to do a lot more revision before Stage 3.
You see this? This is called the sweet sense of victory.
Alrighty so it's time to make Declan's
drink i'm gonna put the ingredients in
this bad boy so let's have a look in the
pantry
tuna fish sauce got some sausages here
let's put some almond milk put a whole capsicum in.
[Music]
Oh that's not good bottoms up
learn your anatomy
All right guys thanks so much for
