In repository.6\Brep\Aalborg\Arm3D\Muscle.any (590), there is an entry
for art_tub_minus_tub_majorRef as a wrapping surface for
pectoralis_major_clavicular_part_4. I’m not sure that is accurate, since
the other parts do not use this. Also, that surface is used for the
deltoids and not for the pectoralis muscle.
Can someone please verify?
Thanks,

Hi Venn
In principle there is nothing wrong in including this surface in the
list of wrappig objects for this muscles. The particular surface is a
sphere with its center at GH. I think if the arm is abducted to 90 deg
and is moved backward there is a small chance that this muscle will
have contact with the glenohumeral head. So in this case it is better
to have the surface listed than not, because if it is not listed the
muscle will penetrate the head of humerus, but as i see it is only
relevant for extreme postures.
A wrapping surface do not belong to a particular muscle like the
deltoid it may be used by all muscles which can possible have contact
with it, this simply means if the muscle comes close to the object
contact will occur. If there is not contact, listing the object will
not influence any results, it will add some cost to the solution time
though.
I have looked into the model and it is correct that it is only branch 4
which has this surface listed, i think it would improve the model if
also branch 5 had this surface listed these two branches of pectoralis
clavicular are the ones which are closest to gh, and have the highest
chance of obtaining contact.

Thanks Søren! I’ll include it in branch 5 as well, since humeral
extension when the arm is abducted (to 80) is one of the motions we
study in the lab.
