scapula. That’s all you need to know. You
don’t have to know anything beyond this.
Then what happens is this artery comes here.
Then you have the outer border of the first
rib. From the outer border of the first rib,
the subclavian artery becomes the axillary
artery. You have the pectoralis minor muscle,
three, four, and five costal cartilage and
it inserts into the coracoid process. That
divides into first part, second part, third
part. Can you name some branches from the
Superior thoracic artery. Superior thoracic
artery, very good, superior thoracic.
No, not thoracodorsal, thoracoacromial,
yeah, lateral thoracic, subscapular, anterior
circumflex humeral artery, and posterior circumflex
humeral artery. So if you remember, it’s
quite logical and it's easy to understand. Remember, you
can imagine, one is going to the superior
part of the thorax because you have the internal
thoracic there because you have the superior
thoracic going to thorax, superior thoracic.
Thoracoacromial, acromion process here, thoracoacromial.
Lateral thoracic, the lateral thorax.
Subscapular, subscapular region. And the anterior
and the posterior circumflex humeral this
way and this way. It’s screw the lawyer,
save a patient. That is your mnemonic for --
Is it one comes from the first part, two comes
from the second part, and three comes from
Yeah. This is it. One comes from the first
part, two comes from the second part, three
comes from the third part. Have we been asked
in part A? I don’t think they ask about
Yeah. This is when you learned --
That’s right, yeah. In part B, it’s very
important. No, no, no, that’s right. No.
You can be asked because this bit of anatomy
is quite important. From the first part, you
have one branch, second branch, these two
branches and third part, in this order. Likewise,
what we've discussed here, even that has got
three parts. The first part has got three
branches, second part has got two branches,
third part has got no branch, but that is
for your subclavian. When it comes to axillary,
first part one branch, second part two branches,
third part three branches.
So this axillary artery is the one we talked
about before. Can you see it coming up here?
Axillary artery coming up here, coming to
the lower border of teres major and then it
becomes the brachial. From that, you have
the profunda brachii artery as your main branch
coming off the brachial artery. Okay. This
is all you need to know about the arteries.
This is quite important, this bit of anatomy
because you’re always asked questions on
this. There're other couple of things you need to remember
are your lung. In the lung, mainly the hilum.
