Brachial artery

Diagnosis History and clinical examination in NTG is similar to PAOG with special attention to some differences. 1) History Special attention should be made to systemic associations and predisposing factors, including migraine, Raynaud’s phenomenon, episodes of shock, systemic hypotension and obstructive sleep apnea. All these factors may contribute to compromised ocular blood flow. (Kanski & Bowling, 2011). 2) Clinical examination There is evidence that the left eye is 2.5 times more likely…

elevated troponins and elevated ST segments on EKG. A 2D echocardiogram showed left ventricular apical akinesis with basal hyperkinesia. He had a coronary angiogram completed, and it showed no stenotic arteries, however they also injected ergonovine which appeared to cause a right coronary artery spasm. The patient was treated with calcium channel blockers and nitrates. A follow up two weeks later showed normal wall motion as well as a sigmoid septum, and normal systolic function. He was…

temporal lobes are the most prone to suffer from an ischemic stroke due to their shared blood supply. The frontal lobe is located within the anterior cranial fossa, whereas the temporal lobe is situated in the middle cranial fossa. The middle cerebral artery (MCA) is the region of interest as this is the most common site for ischemic strokes. The MCA consists of four sections. The M1 segment consists of lenticulostriate vessels which irrigate the basal ganglia. The M2 segment extends anteriorly…

Goy, David The Functions of Blood Blood plays a very important role in maintaining the normal functions of the different, tissues, organs and organ systems in the body. It serves as the primary medium for carrying and transporting important gases, minerals and nutrients needed to maintain homeostasis. Blood is composed of several components: plasma, red blood cells, white blood cells and platelets. Plasma is the fluid compartment of the blood; it carries ions, minerals, nutrients, gases,…

Drowning is known dying due to submersion and inhaling water. Most drownings occur within males and children.

Background information Structure of the large intestine The large intestine (also known as large bowel or colon) is the last part of the gastrointestinal (GI) tract. It extends from the cecum to the anus, with the ascending colon, the transverse colon, the descending colon, the sigmoid colon and the rectum in between. The large intestine consists of four layers of tissue: the mucosa, submucosa, muscle and serosa (figure 1). The mucosa is made out of an epithelial layer, with a layer of…

Blood transfusion is a process in which blood is injected from one healthy human being to a patient; whom might be losing too much blood or suffering from an illness that requires more blood. This medical procedure is crucial in saving numerous lives. The first successful human-to-human blood transfusion was performed by James Blundell in 1818, yet a large number of patients had died because of wrong blood transfusion operations. The great discovery of Karl Landsteiner’s classification of ABO…

by which Mg acts as a facilitator of the sodium-potassium pump in the cell membrane by catalyzing sodium to be released. Mg also acts as a calcium blocker, which would relax smooth muscle in the blood vessels and thus increase the compliance of arteries and decrease blood pressure (BP) (Kass, Skinner, and Poeira,…
