What is the tail vein?

The tail vein is a structure that carries blood back from the tail to the heart in vertebrate. The vein leads to the rear cardinal vein on the back of the animal, which is a common feature of rodent anatomy. Muscle and skeletal structures decrease the size towards the tip of the tail, but the veins remain in the same diameter all the time. As a result, any vein is more pronounced to the distal part of the tail and easily accessible. The walls of the tail veins are elastic and can stretch, so that the tail is a good place for scientists to draw blood from mice or rats. The blood of the mouse is usually pumped from a side tail vein. The primary place of piercing is one third along the length of the tail from the tip. If multiple samples are needed, they can be taken in other places that move towards the base. As in human blood vessels, pressure to stop bleeding after the needle is removed. Vente and in the middle section, which becomes more pronounced compared to the general anatomy towards the tip. In the final segment of the rat's tail is in the final segmentrat only one vein up to 0.15 mm (about 0.006 inches). On the segment closest to the body, the vein is located on each side near the middle line of the tail.

The tail vein can often be achieved without calming the animal. Driving water is usually sufficient to expand the blood vessels and laboratory objects can be returned to their spaces after the procedure is completed. The veins in the tail are also placed under the skin, so they are easier to achieve than the corresponding artery, which is also located under other tissues.

dorsal coconut vein is another vessel of tail blood that can be found in the anatomy of rodents and animals. All these veins form a general formula visible in the anatomy of the tail. Changes in the position of the blood vessels Shpokud are not successful samples successful, they were considered. Veterinary specialists who treat pets and horses are well familiar with the anatomy of the tail. It is also widely studied by laboratory scientists who work with mice and kfeatures and need regular samples to obtain study data.
