Assignment #2: Arm Muscles

This project is due Monday, September 12

 Muscles of the Arm

To prepare for this project as well as the next couple of projects, read Chapter 4 in Goldstein. Our skeletons alone are nothing more than a rack on which to hang our flesh.  In order for us to move, we have a complex system of mechanical moving parts we call muscles.  Many of the familiar landmarks we see on the figure are caused by the muscular structure designed to move rigid bones.

In your sketchbook, you are to draw three views of an arm as accurately, proportionate, and as detailed as possible, with the major muscles from the list provided below neatly labeled.  If possible, address light and shadow. Of these three views, one must be an anterior view, one must be a lateral view, and one must be a posterior view, all of which should be on separate pages and independently labeled.  You may use any detailed arm image in Goldstein (see illustrations in Chap. 4) or research your own accurate image.  Use a finely sharpened pencil to accurately render as many muscles as would be visible in the view that you’ve chosen.  Do not crop your arms at all and be sure to fill your sketchbook page as much as possible without compromising proportion or accuracy.  You may not omit hands.   You are to label your drawings neatly and without compromising the details of the drawing with the list of muscles below.

• Deltoid
• Biceps
• Triceps
• Lateral head of the triceps
• Long head of the  triceps
• Medial head of the triceps
• Brachialis
• Tendonous plateau of the triceps
• Medial epicondyle of the humerus
• Olecranon process of the ulna
• Supinator longus
• anconeus
• Extensor carpi radialis longus
• Extensor carpi radialis brevis
• Extensor digitorum
• Extensor carpi ulnaris
• Flexor carpi ulnari
• Head of the ulna
• Ulnar crest
• Abductor pollicus longus
• Extensor pollicus brevis
• Hypothenar  muscles
• Thenar muscles

Below are some example images from Goldstein.  Your drawings should be just as carefully crafted.
