Bones, joints and muscles
Why this matters
Almost everything a dentist does mechanically is an argument with bone. Whether an injection works depends on what the anaesthetic has to diffuse through; whether a ridge is still there in five years depends on whether a tooth is holding it; and whether an abscess drains into the mouth or into the neck is decided by a line where a muscle attaches. This lesson is the framework the next sixteen lessons hang on.
The big picture
Bone is a living tissue that is continuously replaced, shaped by the loads placed on it and by the structures attached to it. Joints are classified by what fills the gap between two bones, muscles by how their fibres are arranged, and both by what nerve and vessel reach them — and in the jaws every one of those principles has a clinical consequence.
A muscle does not attach at a point but along a line — and that line decides both where the pull goes and where the pus goes.

You have got it when
You are ready when you can say why a bone is an organ rather than a tissue, explain what Meckel's cartilage actually becomes, and predict which tissue space a lower molar abscess will enter.
