Lesson in:

ANATOMY

WARNING!

KEEP IN MIND THAT I AM AN AMATEUR!

DO NOT BLINDLY ACCEPT ANY OF WHAT I'M ABOUT TO TELL YOU AS FACT,

BECAUSE MOST OF IT IS MOST LIKELY WRONG!

Kat foot stuff.

 These are some studies I did a few days back.

Because feet are fucking awful, overcomplicated weird things and they're hard to figure out.

The first picture was my attempt at blocking in the key features of the feet in order to simplify the form.

As you can see in the second image, I wasn't very successful with that.

The geometrical shapes were just way too complicated.

It didn't simplify things at all!

Then I tried drawing the foot's anatomy more clearly and tried to simplify that.

Turns out, much like in the hand, the anatomy of the foot is actually pretty simple already, despite how it looks at first glance.

That is, if you remove all the nonsense bits.

The design of the Tarsus, much like the Carpus in the hand can be completely ignored.

Instead, all you need to know is the length of the big toe and its Metatarsal in relation to the rest of the foot (50/50) an then just picture a line from that middle point towards the heel on the other side of the foot.

The Tarsus looks a lot like the Carpus in that regard.

A curved block that makes up the base shape of the foot where all other bones culminate.

The one thing that deviates from the anatomy of the hand and which is pretty much the most important part of the foot, however, is the heel (Calcaneus).

As important this bone might be, though, it doesn't really matter much how it actually looks like.

All you need to know about the heel is its basic shape at the end (To me it sorta looks like a hammer).

You do not need to know about anyting in between the back end of the heel and the rest of the foot.

Just know that it is there and what it mainly does (move foot up and down and help balance the weight of the body).

Then there are the 'fingers' of the foot.

They work pretty much exactly like the fingers of the hand, except that instead of having a thumb you just have 5 normal fingers.

The thing to keep in mind about the toes is, that the weight rests on the joints between the metatarsals and the Phalanges, which means that, when standing firmly on the ground, the bones of the toes (Phalanges) lie parallel to the ground.

This means that you can simply connect the ankle joint to the base of the toes, which will give you the shape of the top of the foot.

After you figured out how the foot is shaped it's time to give it life.

The muscles that control the foot are easier to figure out than it seems, because at first you see all sorts of tendons running all over the place and each other. Some muscles that move the foot are way up high near the knee, like the Peroneus Longus, which sits just below the knee on the outside of the leg.

You'd never guess that a muscle way up there would have a function as seemingly mundane as moving the small toe.

In fact, the Peroneus is actually one of only visible 4 muscle groups i the leg that move the foot.

 These are:

Soleus and Gastrocnemius:

Attached to the heel.

Main muscle for moving the foot.

Covers the entire backside and most of the inside of the leg.

Move foot up and down and very slighty from side to side.

 Extensor digitorum:

Pulls toes upwards.

Situated right in front of the shin.

Peroneus:

Moves pinky toe metatarsal.

Tibialis:

Moves big toe metatarsal.

That's pretty much all you need to know about the foot, at least as far as I can tell.

Turns out that the foot, beneath its weird shape and confusing tendons, isn't really that hard to fgure out.

More posts on the weekend?

See ya!
