Anatomical variation of the superior thyroid artery and its relation to the external laryngeal nerve.
The thyroid gland is the largest endocrine gland located in the anterior triangle of the neck. It consists of two lobes, right and left, connected by an isthmus in the middle.
The thyroid gland is mainly supplied by the superior thyroid artery, the first branch of the external carotid artery, and the inferior thyroid artery, a branch of the thyrocervical trunk of the subclavian artery; and occasionally by the thyroidea ima artery, an infrequent branch of the arch of the aorta.
The venous drainage of the thyroid gland is into the internal jugular vein through the superior and the middle thyroid vein; and by the inferior thyroid…
The neck is a complex part of the human anatomy. In addition to supporting the head, it serves as a conduit of blood flow and nerve impulses between the brain and the rest of the body. In spite of this essential function, it's highly vulnerable to injury, particularly the carotid and vertebral arteries. The carotid artery is close to the surface of the neck and can be injured by blunt trauma. Both the carotid and vertebral arteries can be injured by rapid or violent motions of the neck or when…

Concussions are violent blows to the head that could seriously damage brain activity. This has been an issue a lot recently because there is a large controversy over former collegiate and professional football players filing Class Action Lawsuits against their respective leagues. These Class Action Lawsuits are for benefits for former players due to negligence of players’ health by the governing bodies of their respective leagues.

Discovered in 1913 by a man named Nikolai Anichkov, atherosclerosis is a disease where things like calcium and fat build up in the arteries and block blood flow. Arteries harden as a result of it, and it’ll cause problems transferring blood around the body. The plaque will form a barrier, and can cause serious problems in the body, like other diseases and disorders. The results are possibly deadly.
There is a layer on the inside of every vein that keeps it smooth called endothelium. It allows…
The giraffe has the longest neck of all animals alive today. But the long neck of the giraffe must work with the circulatory system that brings blood to the brain. Since the brain of the giraffe is located so far away from the heart, the blood pressure the heart generates is approximately two times that of another animal with a similar weight. Due to the high blood pressure, the artery walls of the giraffe must be strong otherwise the giraffe would die of internal bleeding. The blood pressure,…
average, of blood every minute, to the organs, tissues and cells of the human body. This hard working organ, fully matured is only about the size of your clenched fist.
Each cell produces waste products and carbon dioxide. The hearts job is to deliver oxygen and nutrients through arteries, arterioles and capillaries to those cells and remove the produce. Blood is then returned to the heart through venules and veins. Arteries are responsible for moving blood away from the heart. Within most…
