TUTORIALS - The Book of Bones - by Doctor Bone


This is one awesome thread(conceptart.org too), I like the eye angle/tilt thoughts.

Im curious about those DVD’s, are ETA on when you think they will be done?(or maybe they are but I missed) I Wouldnt hesitate for a sec to get them :slight_smile:

Here Is A

Form Units
Of The Upper Leg.

Weekly Sessions At
The Society of Figurative Arts

I just put these in a pile
and the students take what
they want these are some
that were on the floor
or got passed over



the first 2 of your last post are my fav…it helps in understanding planes,light n shadow vry nicely…thanks for sharing

this tutorial thread is absolutly amazing. To bad I just discoverd it today. I’m sure I will come back and try to get as much information out of it as possible. Thank you very much for sharing your studys.

Last week I did 20 gestures from scratch without reference and I had very hard times. Today I read your box and egg tutorial and gave it at try. The 3D box is so usefull to get a proper orientation and idea of the pose. I’ll defenitly stick to that method and will fallow this thread closely.

Thank you!

Oh by the way you were mentioning a DVD is that already available?


I review the function and
form of the body at
least twice a year

The Torso

Pectoralis Major

Here is the start of my review of
the muscles of the torso starting with
the Pectoralis group.

The first task is to determine the form
unit that best describes this muscle group.

The next task is to think about what the
muscle group does.

In this case the “Pectoralis Major” pulls the
arm down and forward.

For almost every action in the human body
that is a counter action.

In other words for every function performed
there is a muscle or muscle group that
performs the opposite function.

In the case to Pectorals the opposition or
opposite function is performed by the
“Latissimus Dorsi” group which pulls the
arm down and backwards.

As I have said, the important thing to
learn is where a muscle starts and where
it ends. In other words, its point of origin
and insertion.

The “Pectoralis Major” has three points
of origin.

A) The inner half of the collar bone

B) The edge of the sternum

C) The coastal cartilage as far as the
sixth and seventh ribs.


The point of insertion is about a quarter of
the way down the upper arm bone.

Note that when the arm is relaxed to the
side the pectoral group has an open fan

The major masses of the front of the
torso are the pecs and the abs so
if you have a grasp of function and
form of these two muscle groups
you have a good start on the front
of the torso.

Finding the center line is always
important and in this case there
is a groove that runs from the
pit of the neck and ends at the
pubic bone.

This line is sometimes referred to
as the “Linea Alba” or white line.

Study from previous review



Here is another
page of pecs


YYYYYYYYYYYYYYYYES THIS was the anatomy key in my brain to unlock what I have known but could not get down THANK, you are amazing Doctorbone. Thank you for sharing your time and knowledge with everyone!

This one of the exercises from
[i]my online figure structure workshop

L’Exerciizio ::: 42[/i]

Torso (Rhomboids and Serratus Anterior)


There are two muscles in the Rhomboid group,
the Rhomboid Minor which originates at the Seventh
Cervical Vertebra and inserts at the spine of
the Scapula and the Rhomboid Major which originates
at the Dorsals down to the fifth vertebra and
inserts at the outer edge of the Scapula

Serratus Anterior:

The Serratus Anterior muscles originate at far
underside edge of the Scapula almost connecting
with the Rhomboid group and insert on each rib
down to the Eight Thoratic sometimes even the

Since both of these muscle group attach to the
Scapula it is obvious that they work together
to pull the Scapula; backward, forward, up and
down. The Scapula is not attached to other
bony structures and floats around the rib
cage with the assistance of these two
muscle groups.

There is a third muscle that gets involved
that we will deal with at some point called
the Levator Scapulae which originates just
behind the Sternal Mastoid and inserts
at the top of the blade of the Scapula.

Were get into the muscles of the Shoudler
next and work are way down the arm.


[I]Here is a little review of
the deltoid and the
muscle group on the
outer layer of the scapula.

We are shooting and
editing on a regular
basis now and hopefully
the DVD’s with start
flowing in the next few

any tips are always welcome, how’s aboyut a tut about properly fleshing out arms and legs?
i finr those to be quite challenging


Thank you Doc, just found and read your fantastic thread. Really looking foward to your DVD and Book. Really enjoyed reading this whole thread and seeing how you have combined the existing knowledge of so many that came before, into an upto date system that we can all use.


insane thread, ive learnt more anatomy in the past few hours than i did in a few months, and its amazing how you just take the simple shapes and convert em into muscles. really helps me a lot, thanks doctah!


Elemento ::: 46

Lower Arm or Forearm

First review # 32 as this
is a refinement of the information
we looked at in the Element.

Here is the first page of new diagramatics.

The forearm is pretty complex and our
species has a far more utilitarian apparatus
than other mammals.

We rotate the wrist by rotation the radius
over the ulna.

The first thing to remember here is that
the ulna is stationary i.e. it does not rotate.

The rotation occurs with the movement of
the radius which rotates over the top of
the ulna.

The next thing is that although there all
many individual muscles involved here we
group them by function and that function
determines their form.

We first try to get a mass conception to
determine the form units involved and in
this case the best solution appears to be
an ovoid that is flattened on the side
where is attaches to the bone.

The next thing to learn here is where
the group start and where it ends.

The three major group are:

1) Extensors - Action (Extend the Fingers)
Origin (Inside condyle of the Humerus)
Insertion (Palm side of the hand)

2) Flexors - Action (Flex the Fingers i.e. closes the fingers)
Origin (Outside condyle of the Humerus)
Insertion ( Back side of hand)

3) Supinators - Action (Rotates the Radius over the Ulna)
Origin (One third the way up the humerus)
Insertion (Follows the Radius to the thumb)

There is also a Pronator muscle
that has an important function
but does not play a major role
in the surface detail.


Thanks so much for posting Doctor Bone - such a great source of knowledge!
