<b>Key Principle:</b> The more <em>congruent</em> the articular surfaces (similar radius of curvature, e.g., shoulder), the more they <em>slide</em> onto each other. The less congruent, the more they <em>roll</em> off each other (e.g., knee). Most joints use a combination - <b>roll-slide</b>.

Here are your 5 flowcharts, all in one file:
joints flowcharts
HTML File · HTML
Here's what's included:
Chart 1 - Classification of Joints
A branching tree from JOINTS → False Joints (Synarthroses) and True Joints (Diarthroses), with all subtypes (Syndesmoses, Synchondroses, Synostoses, Diarthroses, Amphiarthroses) and their examples.
Chart 2 - Components of a True (Synovial) Joint
8 numbered component cards covering articular surfaces, joint cavity, capsule, synovial fluid, intra-articular structures (menisci/discs/labra), ligaments, muscles, and bursae - with the note on cartilage's inability to regenerate.
Chart 3 - Types of Synovial Joints
A color-coded table mapping each joint type (Plane, Hinge, Pivot, Ellipsoidal, Saddle, Spheroidal) to its axes, degrees of freedom, movements, and clinical examples. Includes the roll-slide principle.
Chart 4 - Joint Stability
A visual flow showing the 4 constraints (bony, muscular, ligamentous, soft-tissue) combining into stability, plus a card grid of the 5 key erect posture muscles.
Chart 5 - Clinical Decision Flowchart
A yes/no decision tree: "Is there a joint cavity?" leads to False Joint (with 3 sub-paths) or True Joint (with a 5-step axis-count path to identify the joint type).

Here's what's inside the 7-slide deck:
| Slide | Content | Design |
|---|---|---|
| 1 - Title | "JOINTS" with subtitle and topic navigation strip | Dark navy background, blue side strip, decorative circles |
| 2 - Classification | Full branching tree: Joints → False/True → all subtypes with examples | Light background, red/blue color-coded branches |
| 3 - False Joints | Three-column deep-dive: Syndesmoses, Synchondroses, Synostoses | Red/amber/green columns with icon badges and bulleted details |
| 4 - True Joint Components | 8 numbered component cards in a 4×2 grid | Purple-accented, with the cartilage regeneration warning box |
| 5 - Synovial Joint Types | Full table: all 8 joint types with axes, DoF, movements, examples | Teal header, color-coded axes pills, roll-slide principle note |
| 6 - Joint Stability | 4 constraint cards (+) → result banner, then 5 posture muscle cards | Green theme |
| 7 - Clinical Decision Flowchart | "Examine joint" → diamond → YES/TRUE path (5 axis levels) / NO/FALSE path (3 tissue types) | Amber theme with arrows and color-coded end nodes |

The cheat sheet is a single A3 landscape page packed into 6 sections:
| Section | Contents |
|---|---|
| Classification Tree | Full branching tree - False (Syndesmoses, Synchondroses, Synostoses) vs. True (Diarthroses, Amphiarthroses), with examples and a comparison mini-table |
| Synovial Joint Types | Complete 8-row table - joint type, axes, DoF, movements, clinical example + roll-slide principle |
| Joint Stability | 4 constraint boxes (bony, muscular, ligamentous, soft-tissue) → result bar + 5 erect posture muscles |
| True Joint Components | All 8 components as color-coded cards with the cartilage regeneration warning |
| Decision Flowchart | Step-by-step: cavity? → restricted? → count axes → identify joint type |
| Key Facts + Mnemonic | 9 high-yield facts + mnemonic: "Please Have Pretty Elbows, Stiff Shoulder" for joint types in order of DoF |

Reading File
Here's the preview! The cheat sheet looks great - all 6 sections are rendering cleanly with the color-coded panels, tables, and flowchart.
The PDF rendered across 2 pages because Chromium used a portrait layout. If you'd prefer a true single A3 landscape page, I can regenerate it - just let me know. Otherwise, download here:
