All shoulder muscles end up there at the outer (lateral) side of the arm.
The insertion point of the shoulder muscles as they move down the arm is at the humerus bone. Together they form a circumference around which the shoulder muscles connect. Take a look at the clavicles as well as the spine of the scapulas in this image. Here is a view of the clavicles (highlighted) from the back.
Clavicle bones highlighted.Īs the shoulder muscles connect to the spines of the scapulas on the back of the body, they also connect to a portion of the clavicle at the front of the body. The scapular spine and its medial border are big giveaways to finding the position of the scapula.īelow we will map out the connections of the deltoid muscles to the scapula, as well as look at muscles that originate there and move towards the shoulder joint.Īt the very bottom of this tutorial, we will dive deep into various aspects of the scapula and the clavicle as they come together in the acromioclavicular joint. The knowledge of precise position depending on movement and the figure can only come from practice and from looking at and drawing many, many examples. Rib-cage and spine highlighted.īe prepared to have some trouble identifying the scapula’s position exactly as it glides about the back of the ribcage. Interaction of the scapula and rib cage Front view. We will take a closer look at these attachments below. At the bottom along its ridge, we see the attachment of the shoulder ( deltoid) muscles. The spine of the scapula (or a scapular spine) is an important landmark for drawing the shoulders.Īt the top along its ridge, the trapezius muscles attach. The spines of the scapulas are highlighted. In this diagram (above), we are looking at the back view of the body. We can observe these bones set at the back and connected to the humerus bones of the arm at the shoulder joint, and to the clavicle at the front. Here is the view of the scapulas from the front of the body. Front view of the torso, scapulas highlighted. When the arm is extended to the front, the scapula glides to the side of the rib cage in support of that movement. When the arm is raised the scapula turns upward. I use the word glides because it moves significantly based on the movement of the arm. The scapula bone is a triangular flat piece of bone with a protruding bit on the top – called the spine of the scapula (covered below). The scapula Back (posterior) view of the rib cage and scapula bones. Let’s first look at the bone very involved in the structure of the shoulder and its movement, the scapula. Skeletal anatomy of the shoulder for drawing
Together we can get to a place where shoulder drawing is a strength and not a weakness in our drawings. Stay close to the text as you look over the included shoulder drawing diagrams. I provide numerous drawings to help us along the way. Shoulder anatomy for drawing begins with simple observation of a few major bones but ends with going over many muscles that twist and overlap in ways that can be difficult to remember, as the muscles travel from the back to the front fo the body. With this knowledge, we will draw the shoulders from various angles and with arm raised. We will then dive deep into muscle interaction, looking at precise attachment points, wedging of muscles, and their pull and stretch. In this guide, we will go over the bones involved in the movement of the shoulder muscles, as well as the muscles around the shoulders. Back view, spine of the scapula indicated with red line. Front view clavicle indicated with orange line. Introduction to drawing the shoulders Study by Gvaat.

Study by Gvaat How to Draw the Shoulders – Table of contents My goal in this tutorial is to take you through the required anatomy step-by-step, in an effort to improve your shoulder drawings. Then, apply anatomy knowledge to observation and drawing of the shoulder joint from various angles. To draw the shoulders well, study the skeletal and muscular anatomy of the shoulder joint. What is involved in shoulder drawing is a web of interacting muscles at the shoulder joint, muscles that move and twist as the humerus bone rotates in its socket taking the arm this way and that. Learning to draw shoulders can get very tricky very fast. The scapula – left posterior view, and right anterior view.
