Human skeleton

This section shows the skull: it's a mix of lego sistem and lego technic, and reproduces the movement of the jaw.
It has even a "hole" for the neck to connect and to make possible the rotation of the head in any direction.

In this section is well shown the chest with the breastbone, collarbones, shoulder blades, the bones of the arms and the vertebras.
Due to many reasons, the ribs and vertebras are not so many as in the real skeleton, but they are more or less a half of the real number (12 ribs and 15 vertebras including holy bone).
The movement of the spinal column is well reproducted by the piece of lego technic made of gum (the 2 cross hole beam shaped like a "8" made of black gum, here is coloured in white) that connect all the vertebras allowing them to rotate and to move forward and backward, like the real skeleton.
The ribs are made with the flex rods and all connected to the breastbone.
The arms are able to rotate in any directions with the fisic limit of the lego pieces shape that hold them; the elbow allow the forearm to move like the real human arm, blocking it when the arm and forearm are aligned.

This is the pelvis with aunches, the holy bone, the "holes" for the legs to connect, and the details of the hands.
The holy bone is made of three vertebras linked between them and fixed, they cannot move like spinal column: this is like the real human skeleton.
The legs can rotate in any direction like the arms (they have the same kind of articulation) limited only by the fisical shape of the lego piece that hold them.
You can notice the radius and ulna in the forearm and the connection between it and the hand (the same connection of the arms and legs): this link let the hand rotate in any direction.
The fingers are only four and not five like the real human skeleton because of the shape i gave them with briks; even the movement of each finger is limited. I made this choice because it's a good alliance between the shape of the hand (realistic in my opinion) and the movement it can do.

Here we have the details of the legs with thighbone, shinbone and fibula, the knee-cap and the bones of feet.
The movement of the foreleg is limited by the knee-cap (like the real human skeleton), that block the foreleg when it is aligned with the thighbone.
Feet are made with only 4 fingers instead of 5 for the same reason of the hands.
Feet can rotate in any direction due to the articulations that I used to connect them with the legs.
