Are the jugular vein and carotid artery present on both sides of the neck, or is one on the left side and the other on the right?
There are jugular vein and carotid artery on both side of the neck.
We have four jugular veins, two in each side of the neck. These are called: 1. right internal jugular vein 2. right external jugular vein 3. left internal jugular vein and 4. left external jugular vein.
The term jugular vein, most of the time denotes the two internal jugular veins. They are two in number, one in each side.
Like the jugular veins we have two common carotid arteries in our neck. They are situated one in each side. And are called : 1. right common carotid artery & 2. left common carotid artery.
The two common carotid artery then divide into internal and external branches.

Following picture is a closer and simpler view of the Arteries and veins of the neck (right side). As we have seen from the previous picture the same is true for the left side too.
