Detailed explanation-1: -Left Common Carotid: begins at the level of the second costal cartilage and terminates at the level of the superior border of the thyroid cartilage.
Detailed explanation-2: -There are four carotid arteries, with a pair located on each side of the neck. This includes the right-and left-internal carotid arteries, and the right-and left-external carotid arteries. The carotid arteries deliver oxygen-rich blood from the heart to both the head and brain.
Detailed explanation-3: -The carotid arteries originate posterior to the sternoclavicular joints and in the neck, they are contained within the carotid sheath posterior to the sternocleidomastoid muscle.
Detailed explanation-4: -The common carotid artery is contained in a sheath known as the carotid sheath, which is derived from the deep cervical fascia and encloses also the internal jugular vein and vagus nerve, the vein lying lateral to the artery, and the nerve between the artery and vein, on a plane posterior to both.
