STRUCTURE - Research Point

Anatomy
Very often when a figure is wrong it easy to see without always knowing exactly what it is. That’s why it is important to have an idea of what is going on deep down under the surface of the skin to appreciate what’s happening close the surface.

On the skeleton there are places where the bones are very near to the overlying skin and these places are visible on most people, even those very overweight. Apart from many points on the head such as the forehead, cheekbones and chin, elsewhere there is also the wrist and anklebones amongst others. These areas are seen as depressions between the main muscle masses and sometimes as projections on thin people.

Although each person’s body shape is unique, all human bodies work in a similar way. The muscles and their connections are made up of a contracting and expanding system of pulleys, shock absorbers and self lubricating hinges. They are interdependent with the skeleton and without bones, the muscles would not hold together. Muscles connect two different bones, passing over one or more joints. An example is the calf muscle where its origin is on the upper leg bone and its insertion on the heel bone. It pulls the heel up and toes down when it contracts. This gives forward propulsion to the body when walking. The pelvis and buttock muscle (gluteus maximus) are the primary support for the backbone and are most important in establishing the balance of the figure. The legs have very mobile joints with the pelvis and support the weight of the rest of the body. This is the major difference between humans and animals.

My own version

In drawing the body being able to recognize the main muscle groups is very helpful in selecting which forms are the most significant. It helps in placement of lines (lines between  functions) at meeting points even though they are not visible on the figure.

I knew from looking at this drawing that it is very complex. I didn’t intend to copy the whole figure at one go and soon after I started I began to realize just how complicated it is. 
 There are many muscles clustered around the top of the lower arm but each one can be broken down into just three groups: the supinator – rotates the hand, flexor - flexes and extensor – extends. The muscles in the hamstrings are also grouped in a similar way. The undulating lines both for the outlines and for those of the muscles really give a strong sense of movement.  My own version certainly doesn’t live up to this description.

Anatomy Sketch – from John Raynes Book

I found this drawing more enjoyable than the previous one. Some of the shapes and angles were inaccurate in on my first attempt, so I adjusted these. The most interesting part was doing the sketchy lines heading in multiple directions and the way they flowed into one another.

On comparing this drawing with the life drawing I did of the standing pose (one of the 3 Drawings exercises) it was easier to imagine much of the underlying muscle structure. I also noted how the hands in the illustration I referred to are drawn with a real feel for the underlying skeleton. When copying them I found it was easier to convey lifelike hands than previously. I hope this trend will continue unabated, but I'm not holding my breath. However, drawing the subject rather than just looking at the anatomical drawings, really seemed to help me to absorb the information more easily.

Rodin’s Seated Nude

This to me is a good example of how  flowing and undulating outlines make out the rounded forms as in that of the ribcage, the shapes of the major muscles and where the bones are close to the underlying skin.
