External carotid artery

superior and inferior. Next we have the right atrium, from the right atrium the flows through the tricuspid valve. Upcoming the blood flow goes through the right ventricle, to the pulmonary valve, succeeding to the pulmonary artery than to the right and left lung. On the left side of the heart we have pulmonary veins the blood flow continues to the left atrium, through the bicuspid valve. The following the blood goes through the left ventricle to the aortic valve, than to the aorta, to the rest of the whole body. The heart is a very complicated…

Title Anatomical variation of the superior thyroid artery and its relation to the external laryngeal nerve. Introduction 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…

peripherally administered TPA (tissue plasminogen activator). However, Dr. Philips documented Dr. Kilpadikar called with the result of the CT and stated that there appeared to be a hyperdense MCA (middle cerebral artery) sign. Dr. Philips documented with those findings, Mr. Green did meet relative contraindication for peripheral TPA. Therefore, Dr. Phillips documented while at the bedside, he discussed these findings with Mr. Green and his sister. Dr. Phillips documented Mr. Green remained…

At first, the surgeon had to check for any defects and repair them; I remember him saying it’s either a straight forward case or a complicated one. Ours was the second type of transplant. It was mesmerizing and breathtaking to see how the kidney became viable and pinkish after he connected it to the external iliac artery and vein. I enjoyed observing the surgeon while checking for any bleeding at the suture lines to make sure everything went smooth. I remember the next day when we were rounding…

bring blood to the head, neck, and arms. Innominate artery, sometimes referred as brachiocephalic trunk begins at aortic arch (second branch) and ends at the carotid bifurcation. Innominate artery travels upward and give rise to the right subclavian artery and the right common carotid artery. It supplies blood to the right arm, head, and neck. Right Subclavian artery and Left subclavian artery, On the left side of the body the subclavian comes directly from the aortic arch and ends at the…

Femoral Popliteal Bypass A femoral popliteal bypass is a procedure to go around (bypass) a blocked artery in the leg. The artery may become blocked with plaque, which is a buildup of fat. Arteries carry oxygen and nutrients to the body. The femoral artery is in the upper part of the leg. It is the main artery that carries blood to the leg. Popliteal arteries are in the back of the knee. These arteries take blood to the lower part of the leg. This procedure uses a graft to bypass the blocked…

from heart to different part of the body, are called arteries. They constitute a system called arterial system. Truncus arterious gives two branches right aortic trunk and left aortic trunk. Each aortic trunk again divides into three branches- a) Carotid arch: it divides into – Lingual artery – it supplies blood to tongue and hyoid. Common carotid – it supplies blood to buccal cavity and brain. it consists swelling at the base called carotid labyrinth. b) Systemic arch – two systemic arches…

Homeostasis is a key factor in helping the body to maintain optimum conditions for life. It aids in keeping a steady environment inside the body when the external environment is constantly changing. ( Peate, I. and Nair, M. 2011) Humans need to maintain a near constant environment internally to be able to function and to survive. There are various control systems at work in the process of homeostasis, such as negative feedback and the receptor, controller and effector loop. The receptor,…

Jugular Veins The most accessible veins for examination are the internal and external jugular veins in the neck. Both veins drain bilaterally from the head and neck into the superior vena cava. The external jugular vein lies superficially and is just above the clavicle. The internal jugular vein lies deeper, along the carotid artery. It is best to examine the right internal jugular vein because it follows a more direct anatomical path to the right atrium of the heart. The column of blood inside…

when standing, the only other variable is PP. In A study performed by Harms et al., in 1999, witnessed a trend of SV decreasing for tilt and for recovery, however recovery was still larger than that of the drop in tilt SV. This study illustrated what results were expected and also shows how PP should have had a similar trend. Physiologically, reason the SV drops initially is the same reason the MAP drops as well, gravity. The baroreceptor reflex, is why the SV should have increased in the…
