What is an outer jugular vein?
The outer jugular vein is the main blood vessel of the head and neck. It comes just behind the jaw and under the front of the ear on the right side of the head, running on the right side of the neck towards the collarbone. This vein is responsible for collecting blood from the external areas of the head - from the vessels surrounding the skull and penetrating into the face - and returning to the heart. It must not be confused with two inner jugular veins that transport blood from the brain back to the heart. In particular, two veins form a point of origin for the outer jugular at their intersection: retromandibular vein and rear auricular vein. As the name suggests, the retromandibular vein is located just behind the jaw or jaw, where I have the rear branch becomes an outer jugular. Similarly, the rear auricular is awarded the name for its location, which is just behind the ear or ear. These vessels slightly forward under the ear earlobe ear and merger with a retromandibular vein and form a larger outer jugular vein.
runs vertically down the back or rear aspect of the jaw, differs from the jaw to descend on the right side of the neck towards the collarbone or collarbone. Along the upper two -thirds of its length is superficially or externally on sternocleidomastoid, the main muscle of the side of the neck. The lower third of the outer jugular vein passes through the rear limit of the muscle, where it connects with the subclastic vein, a large blood vessel that returns blood from the arm to the heart. This occurs just behind and under the horizontal bone of the collarbone in the center.
In total, the outer jugular vein expands approximately 6 inches (15.24 centimeters) in length, although this may vary depending on the size of the person. Eight other veins branch out of the outer jugular. Five of them are the main veins of the neck and faces: the ascending pharynx vein of the neck, the vein of the thyroid scale, the lingual vein of the tongue, the facial vein of the face and the occipital vein of the skull base.
outer jugular vein is only covered with platysma, wide, flat musclethat descends the front side aspect of the neck from the chin to the upper chest and above this fat and skin. Since it lies so close to the surface, it is vulnerable to damage to the accident and injuries. In addition, because it transports a relatively large volume of blood, the interruption of the external jugular may show fatal.
