The artistic anatomy of the leg is, in practice, fairly simple. However, we will need to look at some things hidden well under the skin to get a real understanding of the leg’s structure, and this may at times seem a bit complicated. I think that if you bear with me, you will see that this complexity is really pretty easy to manage.
We’re going to start with the leg as seen from the front. And we will need to start with the skeleton.
Here are sketched the bones of pelvis and leg, and the outlines of the musculature:
At this point, we are really only concerned with four bones: pelvis, femur, tibia, fibula and patella (kneecap). The bones of the foot will be dealt with in a separate tutorial.
The muscles of the thigh which are seen in a front view fall into two main groups. I am calling them here the “Thigh Muscles” and the “Adductors.” The adductors are the muscles we use to pull the leg towards the body’s centerline. The “Thigh Muscles” are the muscles we use to straighten the leg, as in rising from a crouch, leaping up, sprinting from the starting block — obviously very important muscles.
Between these two groups runs a long flat band of muscle, the sartorius (shown here in yellow).
The thigh muscles, actually a group of three muscles, mainly connect to the upper end of the femur, and gather below to connect at the kneecap.
The adductors connect the underside of the front of the pelvis, to the inner surface of the femur, along most of its length.
A short mass of muscle, the gluteus medius, connects the outer rim of the pelvis to the outer corner of the head of the femur. It functions to swing the leg out.
We can simplify things a bit, for a moment, by temporarily taking the femur out of the picture. This gives a good view of the way the thigh is shaped by the two main muscle masses.
Below the knee, we are mainly concerned with two muscle masses: the foot extensors, and the calf muscle (gastrocnemius). The calf muscle is a muscle of the back of the leg, of course, but it can be seen from the front, on either side of the extensor muscles and the tibia/fibula.
In the muscles which lie on top of the tibia, there is long gap between the foot extensors and the calf muscle. The shin bone can be felt right under the skin, in this gap, which faces forward and a little towards the centerline.
The calf muscle connects the lower end of the femur to the hind end of the foot (the heel bone).
The foot extensors connect the upper end of the tibia and fibula to various places on the foot, and are what we use to raise our toes and/or the ball of our foot off the ground.
Finally, on the outer side of the knee we can see, in a front view of the leg, the lower end of the biceps femoris, one of the muscles we use to bend our leg. It is mostly hidden here by the front thigh muscles.We will get a better view of this muscle and others in the tutorial on the rear view of the artistic anatomy of the leg.
Getting some bones out of the way, again, we can get a clearer and simpler view of the main muscle masses.
As I said before, it’s actually fairly simple.
Here is a sketch of the front view of the leg, showing the surface forms made by the bones and muscles we’ve been looking at.
Tutorials to come (not necessarily in this order): back view of the leg, outer side view, inner side view, changes of forms with bending at hip and/or knee, example sketches.
