Learn muscle anatomy with a Halloween skeleton

I wanted to learn muscle anatomy for drawing.  But I wasn't confident about the arrangement of muscles just from drawing them in two dimensions.


I notice that most anatomy books don't show you how the whole muscle looks by itself, only how they look all bundled together.  And they also tend to show muscles colored in red, which makes it a little harder to discern them individually.

These Halloween skeletons are not truly anatomically correct, usually.  They are fairly simplified.  But their proportions are more or less close enough.  I'm primarily interested in the superficial muscles, as they apply to drawing, so I'll be simplifying it too.

Step 1: Materials

small plastic skeletons from the Dollar Store    $1.00
bake and bend sculpey mixed into muted colors     $7-$8

optional: pin vise, small drill bit and large jump rings for jointing the arms.

You could try this with Sugru if you're fast enough.  Though I worried that the 30 minute working time just wasn't enough.  Note:  Sugru does seem to bond to these plastic skeletons reasonably well.



Step 2: Muscles of the upper leg

adductor brevis
adductor magnus
adductor longus
pectineus
gracilis
vastus medialis
vastus lateralis
rectus femorus
gluteus maximus
sartorius
biceps femoris
semitendinosus








 

Step 4: Muscles of the torso and upper arm

biceps brachi
pectoralis minor
pectoralis major
deltoid
rectus abdominus
serratus anterior
external obliques




Step 5: Muscles of the back and upper arm

trapezius
latisimus dorsi
triceps
supraspinatus, infrapinatus, teres minor
rhomboids



Step 6: Muscles of the lower arm

pronator teres
(I'm a little fuzzy on these lower arm muscles, they may be a bit mixed up)
flexor carpi radialis
palmaris longii
brachioradialis
anconeus
abductor pollicis
extensor pollicis
extensor group

I know I'm skipping a huge number of muscles in the lower arms.  its very complicated.




Step 7: Neck muscles

sternocleidomastoid

trapezius

there are others, but this skeleton is too tiny to do the neck muscles!

Step 8: Muscular fellows showing off their physiques


I don't dare bake the sculpey because I'm pretty sure these plastic skeletons couldn't withstand the heat.  Maybe I'll try again using sugru to make it more permanent.

I didn't do the hands, feet or facial muscles because the skeletons are just too small.   Maybe in another instructable.
