Types of arteries Arteries are generally classified into three types: Elastic artery Muscular artery Arteriole In the tunica media of elastic arteries, there is one elastic lamina for each layer of smooth muscle fibers so it is a 1:1 ratio of elastic lamina to smooth muscle. While elastic arte...
Material and Methods: The study of renal arteries and their variations were done in 50 sides of 25 embalmed human cadavers in the routine educational dissection of I M.B.B.S students for three consecutive years (2013- 2016) in our department of anatomy. Exposure of the kidneys and the ...
Coexistence of two types of Ca2+-activated K+ channels in rat renal arterioles.Examines single-channel potassium currents in arteriolar smooth muscle cells isolated from preglomerular arteries of the rat. Characterization of two distinct voltage-sensitive, calcium-activated potassium channels; Differences ...
The thin layer of tissue (periosteum) that surrounds bones, muscles that encase the skull, sinuses, eyes, and ears, as well as thin tissues that cover the surface of the brain and spinal cord (meninges), arteries, veins, and nerves, all can become inflamed or irritated and cause a ...
High blood pressure (hypertension) occurs due to the tightening or stiffness of very small arteries called arterioles. As a result, the heart pumps harder through the stiff or narrow arterioles, leading to elevated pressure inside the vessels. Hypertension is known as 'the silent killer' because ...
Blood flow through the umbilical veins and arteries dries up. The blood vessels closest to the navel degenerate and become part of the stomach wall and the interior parts become integrated with the body's circulatory system. What organ is directly behind the belly button? The intestines are the...
Although there are many types of cells in the human body, they are organized into four broad categories of tissues: epithelial, connective, muscle, and nervous. Each of these categories is characterized by specific functions that contribute to the overall health and maintenance of the body. A di...
Atherosclerotic burden in coronary and peripheral arteries in patients with first clinical manifestation of coronary artery disease The aim of our study was to assess the atherosclerotic burden in patients with the first symptoms of coronary artery disease (CAD). The study population co... A Cerne,...
The investigated stents are made from different materials (stainless steel (316 L), nitinol, cobalt superalloy, tantalum, and platinum-iridium alloy) and for different areas of application (arterial and peripheral arteries in general, biliary duct, carotid arteries, renal arteries, iliac arteries,...
(e.g. due to obstruction or atherosclerosis of the coronary arteries). Cardiac ischemia decreases the amount of adenosine triphosphate (ATP) in heart cells leading to acidosis. This acidosis then stimulates the myocardial nerve cells creating an increase in adenosine, which sends painful stimuli to...
