Muscle Insertion/Origin Locations

Hello,

I’m trying to find the loctions of certain muscle segments in relation
to others labeled for the same muscle. For example the
trapezius_scapular muscle has 6 individual segments representing the
muscle. Currently I was able to find the relative locations of these
6 segments by finding their origin and insertion points and then
plotting them in MatLab to get a 3-D image of their layout. I was
wondering if their was a simpler way to find their relative locations
or if there were screenshots labeling the individual segments, i.e.
trapezius_scapular_1 and trapezius_scapular_2. Also is there
anatomical names for the origin/insertion points instead of having to
use the coordinates from I_trapezius_scapular_1 and
O_trapezius_scapular_1.

Thank you for your time.

Hi Nick

Welcome to the group

I will try to answer your question

If you are looking at the arm you could open the file
BRep/aalborg/arm3d/Muscle.any.

This is the file which defines the muscles in the arm. Each of the
muscles have a line saying :

AnyDrawMuscle DrwMus =
{#include “…/drawSettings/MusDrawSettings.any”};

This is what defines the graphical representation of the muscle. If
for example you changed this line to be:
AnyDrawMuscle DrwMus = {RGB={0,1,0};};

The muscle would appear green, this would allow you to see which
muscle you where manipulating.

I am not sure i understand your last question. If you look at the
muscles in the Muscle.any file you will see that each muscle points
at a origin and insertation node. The nodes that the muscle is
pointing at needs to be real nodes with a location speficied by an
sRel. It can not be “anatomicalnames” unless these names are the
defined as AnyRefNodes, Segments etc.

I hope this answers your questions, otherwise please do not hesitate
to write again.

Best regards
