| − | Bone is a relatively hard and lightweight composite material, formed mostly of calcium phosphate. It has relatively high compressive strength but poor tensile strength. While bone is essentially brittle, it is somewhat elastic due to its organic components (chiefly collagen). Bone has an internal mesh-like structure, the density of which may vary at different points.

| − | # '''Ball and Socket''' joints can be found in the hip. These joints allow for movement in many directions.
| |
| − | # '''Ellipsoid''' joints can be found in the knee. When the knee is extended, it does not allow rotation. When it is flexed, it allows for limited rotation.

| |
| − | # '''Pivot''' joints can also be found in the elbow between the ulna and the radius. This type of joint allows one bone to rotate about the other.
| |
| − | # '''Gliding''' joints can be found between the carpals in the wrists. These joints allow limited movement between the bones as one glides past the other.

| − | Approaches to constructing a model include:
| |
| − | # Form the bones with clay and then let them harden.
| |
| − | # Cover wooden dowels with papier-mâché.
| |
| − | # Make a wire frame and cover that with papier-mâché.
| |
| − | # Carve bones out of soft wood (such as balsa or pine).
| |
| − | # Make an impression in wet sand and fill with plaster.
| |
| − | # Make cross-sections out of paperboard and glue them together.
| |
| − | # Make the bones from sugar cookie dough and then bake them (a saddle joint or gliding joint works best for this approach).
| |
| − | # Use Pathfinders to model the bones and muscles in a joint. A simpler joint like the elbow is easiest. Make sure each Pathfinder knows the name and function of the body part he/she is modeling.
| |
| − | Be sure to review requirement 17 before starting. It's important to know how this model will be used during the design phase.

| − | Another name for a broken bone is "fracture." There are two main types of fractures, '''open''' and '''closed'''. In an open fracture (also called a compound fracture), the bone protrudes through the skin. This is a very serious condition as it allows infection to enter the body. In a closed fracture (also called a simple fracture), the bone stays inside the body.
| |
| | | | |
| − | Sub-categories of fractures include:
| + | {{clear}} |
| | | | |
| − | '''Transverse''' - the break in the bone is at a right angle to the long axis of the bone.
| + | {{clear}} |
| | | | |
| − | '''Comminuted''' - the bone breaks into three or more pieces.
| + | {{clear}} |
| | | | |
| − | '''Greenstick''' - the bone breaks on one side, and the other side is bent. This is very similar to what happens when a green twig is snapped: it doesn't come all the way apart, but it is clearly broken on one side.
| + | {{clear}} |
| | | | |
| − | '''Stress''' - a hairline crack in the bone. The bone does not separate into two pieces.
| + | {{clear}} |
| | | | |
| − | Living bones are in constant change. Cells die and are replaced on a regular basis. Because of this, a bone will heal all by itself if allowed to. Doctors can help this process in two ways. First, they can '''set''' the bone. This is done by making sure the pieces of the bone are aligned properly. In a comminuted fracture this may involve surgery. The second way that doctors help bones to heal is by immobilizing them - that is, keeping them from moving around. This can be done by surrounding the broken limb with a cast, or it can be done by embedding pins inside the body. Some bones do not need to be immobilized when broken (such as the nose).

| − | Osteoporosis is the depletion of minerals from the bone. Minerals in bones give them their strength, so a bone with a low '''b'''one '''m'''ineral '''d'''ensity (or BMD) is more susceptible to breakage, even when stressed only lightly. Anyone can get osteoporosis, but it is more common in postmenopausal women. Some of the risk factors of getting osteoporosis cannot be reduced by modifying behavior (such as being a woman, having dementia, having a family history of weak bones, or being of European descent), but other factors are easily avoided by healthful living. These health habits include:
| |
| − | # Avoid soft drinks, especially those containing [http://en.wikipedia.org/wiki/Phosphoric_acid phosphoric acid].
| |
| − | # Avoid alcohol.
| |
| − | # Avoid tobacco.
| |
| − | # Maintain a healthy body weight. Those with abnormally low body weight are more susceptible to osteoporosis.
| |
| − | # Make sure your diet has plenty of calcium.
| |
| − | # Make sure your diet has plenty of vitamin D.
| |
| − | # Get plenty of exercise.

Involuntary muscles are controlled by the autonomic system without the conscious control by the individual. Your heart continues to beat, you continue to breathe, and you digest your food even when you are not thinking about it.

Although they will not contract, they look kind of like muscles and taste pretty good.

| | | | |
| − | *If you use clay, plaster, or papier-mâché, be sure to make anchor points for the muscles before the "bones" harden. Try using cup hooks or eye hooks for this purpose. If using a wire frame, you can make the anchors out of the wire.

This is usually more easily achieved if everyone is lying down, so gravity is less of a factor.
