SUMMARY
1. As a needle advances toward a target starting with an oblique projection, its trajectory can be broken into two predominant vectors: medial and ventral.
2. After a needle is embedded in a tissue and on its given path, placing the notch laterally will drive the needle tip medially.
3. Placing the notch medially will drive the needle tip ventrally.
4. if a needle trajectory is less oblique and more perpendicular to the skin surface (Fig. 2.11), then a lateral needle tip movement can be achieved.
