Ecorche Armature Design

Available here is my design for the Ecorche Armature

I've assembled detailed plans and explanation for building your own Ecorche Human Anatomy Armature.

I currently teach Artistic Anatomy- Drawing the Human figure at the Woodstock School of Art in Woodstock, New York for the last six years. I have also taught a class in Sculptural Ecorche.

My first Ecorche was with Eliot Goldfinger at the New York Academy of Art in New York.

I've had quite a bit of experience in building these Ecorche armatures as I've fabricated about ten of these and have perfected my design on each succesive one that I build.

For those interested in purchasing one I have a few available through this website as  well as detailed plans for how to fabricate your own Ecorche armature.

They can be obtained here:

Half Skeleton Muscle Demo Prop

I've been using this armature I made from an articulated plastic skeleton to demonstrate muscle origin and insertion. It's a old somso cast I believe, so the detailing is better than a Bucky. After extensive use, it started to fall apart so I tweaked the armature using 3/8" galvanized pipe and a 1/2" conversion coupling to 1/2" nipple and phlange.so now it's ready to go.

This time I'm going to use the kleen klay unsulpherated terra cotta color.... it's more life like.

Muscles of the Neck- Anterior

Here's a survey of the Anterior Neck muscles for the Ecorche.

The Larynx

The structure of the Larynx

 

Frontalis muscle

The frontalis muscle, also known as the occipitofrontalis or epicranius, is thin, of a quadrilateral form, and intimately adherent to the superficial fascia. It is broader than the Occipitalis and its fibers are longer and paler in color. It is located on the front of the head.

It has no bony attachments.

Its medial fibers are continuous with those of the Procerus; its immediate fibers blend with the Corrugator and Orbicularis oculi, thus attached to the skin of the eyebrows; and its lateral fibers are also blended with the latter muscle over the zygomatic process of the frontal bone.

In the eyebrows, its primary function is to lift them (thus opposing the orbital portion of the orbicularis), especially when looking up. It also acts when a view is too distant or dim.

From these attachments the fibers are directed upward, and join the galea aponeurotica below the coronal suture.

The medial margins of the Frontales are joined together for some distance above the root of the nose; but between the Occipitales there is a considerable, though variable, interval, occupied by the galea aponeurotica.

It could be part of occipitofrontalis muscle.

Muscles of the Head

This is a compendium to the Ecorche survey.

In this installment I'll be presenting an overview of the muscles of the skull and their
influences on surface anatomy.function, and expression.

Edward Lanteri, in the classic  Modeling and Sculpting the Human Figure, divides the muscles of the head into seven groups.Masticatory, Epicranial, Auricular, Ocular, Palpebral, Nasal, and Labial.. Palpebral refers to the palpebral fissure or the "eye opening" which together with the Ocular,Nasal and Labial and with some limited movement being contributed by the frontalis of the epicranial group, compromise the muscles of expression.The Masticatory, or muscles of chewing, include, the Temporal, the Masseter, the Internal Pterygoid, the External Pterygoid, and the Buccinator muscles.For the student of Drawing and Sculpture, the moving muscles of the head can thus be further simplified to the muscles of chewing/nourishment acquisition which are primarily side plane, and the muscles of expression which are primarily front plane.

Constructing the Skeleton

The first step in modeling the skeleton onto the armature is of course to choose thr right kind of clay substrate for the sculpture.  Ecorches are modeled in non drying plastilina to facilitate the evolution of the modeling process and in addition to prevent details from drying and chipping away from the armature as would be a problem using wet clay, although I'm sure Houdon's majestic Ecorche he fabricated was in natural terracotta.After much experimentation and numerous Ecorches, we have chosen the non sulfurated Kleen Klay and for aesthetic reasons have chose to model the skeleton in ivory colored clay and apply the muscles in the terra cotta color.

The Armature

The Ecorche armature

Central to the building of the Ecorche as it is to any sculpture is the internal foundation onto which the clay conforsa and acquires its stability. The armature for the Ecorche is designed to be embedded inside the skeleton and to support the delicate framework onto which the muscles are built.After much experimentation, a sturdy and lightweight armature was constructed from galvanized 3/4"pipe nipples, couplings and phlange along with various gauges of aluminum armature wire , threaded steel rod, fittings and hardware.

A sturdy plinth was constructed from 7/8" Luan ,pine planks underneath to minimize warping and a pine pedestal through which lock nuts and armature wire could be inserted.
