Final answer:
The hub is the part of the needle that attaches or screws onto the syringe, ensuring a secure connection for precise and safe medication administration.
Explanation:
The part of the needle that attaches or screws onto the syringe is called the hub. When you are preparing a syringe, you typically hold it in such a way that the volume markings are visible, and connect the needle with its hub facing upwards. After attaching, if the needle is bent, it should point downwards, allowing the practitioner to view the volume markings during the process of withdrawing liquid—this avoids the inconvenience of having the markings on the back face of the syringe. The hub is an essential component, as it ensures a secure connection between the needle and syringe, minimizing the risk of leaks or needle detachment.
