A hypodermic needle is a medical tool used to inject substances under the skin or into a body cavity. It is composed of a sharp point at one end to penetrate the skin and a hollow tube or cannula at the other end to carry the substance into the body. The point and the cannula are usually made of stainless steel, but may also be made of other materials such as glass or plastic.
The point of the hypodermic needle is first disinfected with alcohol or another disinfectant. The person receiving the injection then relaxes the skin around the injection site by compressing it between the thumb and forefinger. The hypodermic needle is then inserted into the skin at a 90-degree angle and the substance is injected by depressing the plunger on the syringe.
The most common use of a hypodermic needle is to inject drugs under the skin, but they can also be used to draw blood or to inject other fluids into the body. They come in a variety of lengths and sizes, but the most common length is 18 to 26 gauge. The gauge is a measure of the thickness of the needle and the higher the number, the thicker the needle.

What are the parts of a hypodermic needle?
A hypodermic needle is a medical device that is used to inject substances into or withdraw fluids from the body. The needle consists of a hollow tube that is inserted into the body, and a sharpened tip that is used to pierce the skin. The tube is connected to a syringe, which is used to inject or withdraw the substance.
The needle consists of three main parts: the barrel, the plunger, and the needle itself. The barrel is the part of the needle that holds the substance to be injected or withdrawn. The plunger is the part of the needle that is used to push the substance into or out of the barrel. The needle is the part of the needle that is inserted into the body.
The barrel, plunger, and needle are all made of metal. The barrel is typically made of stainless steel, and the plunger and needle are typically made of brass. The barrel, plunger, and needle are all coated with a layer of latex or plastic. This layer helps to protect the user from the metal, and it also helps to keep the substance inside the barrel.
The needle is attached to the end of the plunger. The needle is inserted into the barrel, and the plunger is pushed down to inject or withdraw the substance. The needle is also attached to the barrel by a connector. This connector is used to connect the needle to the syringe.
The hypodermic needle is a safe and effective way to inject or withdraw substances from the body. It is important to use a new needle for each injection or withdrawal.
What are the parts of a needle called?
Needles come in all shapes and sizes, but they all have the same basic parts. The part of the needle that goes into the fabric is called the point, and the part that you hold is called the shank. The part of the needle that curves is called the eye, and the thin wire that holds the eye in place is called the wire.
What are the 3 parts of a syringe?
A syringe is a medical device that is used to inject liquids, such as medication or vaccines, into the body. Syringes are typically made of plastic and consist of three main parts: the barrel, the plunger, and the needle.
The barrel is the longest part of the syringe and is where the liquid is stored. The plunger is a metal or plastic rod that is used to push the liquid out of the barrel and into the body. The needle is attached to the barrel and is used to inject the liquid into the body.
Most syringes come with a protective cap that covers the needle. This cap is removed before the needle is inserted into the body. Syringes can be purchased at most pharmacies and drug stores.
What are the 4 parts of the needle?
The needle is a small, pointed piece of metal that is used to sew fabric together. It is inserted into the fabric, and the thread is passed through the eye of the needle. There are four parts to the needle: the point, the eye, the shank, and the barrel.
The point is the sharp end of the needle that is inserted into the fabric. The eye is the hole in the middle of the needle that the thread is passed through. The shank is the part of the needle that is attached to the eye. The barrel is the part of the needle that is inserted into the fabric.
What are the 5 parts of the needle?
When it comes to sewing, needles are an essential tool. There are many different types of needles, but all have the same basic parts. Here are the five parts of a needle:
1. The Point – This is the sharp end of the needle. It’s used to pierce the fabric and thread.
2. The Shank – This is the long, thin part of the needle. It’s the part that the thread is attached to.
3. The Eye – This is the opening at the top of the needle where the thread is inserted.
4. The Groove – This is the indentation on the shaft of the needle that helps the thread glide smoothly through the fabric.
5. The Pointed End – This is the blunt end of the needle. It’s used to push the fabric away from the needle point and hold the fabric in place while sewing.
What is that plastic thing on a hypodermic needle?
When you see a hypodermic needle, there is often a plastic thing on the end of it. This is called a plunger and it is used to push the medicine through the needle and into your skin. The plunger is also used to get all of the medicine out of the needle after you have injected it.
What are the 5 parts of a needle?
There are five parts of a needle: the eye, the shaft, the point, the bevel, and the taper.
The eye is the hole in the center of the needle. The shaft is the long, straight part of the needle. The point is the sharp end of the needle. The bevel is the slanted edge of the needle. The taper is the gradual decrease in width from the point to the eye.
