By donating a person can save up to eight different lives with donating organs and even help the lives of hundreds others through tissue donation (Life center Northwest). There is millions of people around the world in need of organ or tissue donation. Dating back to the Middle Ages is a way to save lives and cure illnesses and injuries (History of Organ and Tissue Transplant). Since scientific knowledge was limited back then, modern transplantation was not successful until the 19th and 20th…

The inflammatory response is the body's natural response that happens straight away following tissue damage. The main functions are to protect the body against harmful substances, dispose of dead or dying tissue and to promote the renewal of normal tissue. There are some signs of Inflammation are a lot of pain because of the chemicals released by damaged cells. Another sign is swelling because of an influx of fluid into the damaged area. One more sign is redness which is due to vasodilation-…

surroundings and environment. It helps with emotion and memory. The cells in the nervous tissues need to be able to communicate with each other by using electrical nerve impulses. The functions of the nervous system are: • Sensory input • Integration • Control of muscles • Control of glands • Homeostasis • Mental activities Extra information on muscle tissues: Muscle tissues like the skeletal muscle tissue are often referred to as striated because of its’ exterior, which are made up of dark…

damaged eye surfaces. PROKERA® is made by clipping a piece of amniotic membrane tissue in between two rings made out of a clear, flexible material. What is amniotic membrane tissue? Amniotic membrane is part of the placenta. It is the tissue closest to the baby throughout development in the womb. Amniotic membrane protects the baby from any harm and it has natural therapeutic actions which help the baby develop. This tissue has healing properties that aid in ocular surface repair Where does…

The Tissue Issue When it comes to the topic of patient consent on the removal of body tissue, most of us readily agree that consent must be granted before anything is removed from the body. Where this argument usually ends, however, is on the question of whether or not the patient is aware the tissue removal is happening. Whereas some are convinced that at times making the patient unaware of the removal is adequate, others maintain that everything happening in a medical procedure should be…

flattened, a hinged flap of corneal tissue is created using an automated microsurgical device, either a laser or blade. This corneal flap is lifted and folded back (figure 1). Then the excimer laser preprogrammed with the patient's unique eye measurements is centered above the eye. The surgeon checks that the laser is positioned correctly. The patient looks at a special pinpoint light, called a fixation or target light, while the excimer laser sculpts the corneal tissue. Then the surgeon places…

Ischemia is a state of tissue oxygen deprivation accompanied by a reduced washout of the resulting metabolites (1). Reperfusion is the restoration of blood flow to the ischemic tissue. Despite the unequivocal benefit of reperfusion of blood to an ischemic tissue, reperfusion itself can elicit a cascade of harmful reactions that injure tissue(2). Studies have shown that renal ischemia - reperfusion injury in addition to kidney tissue, will also be affected distant organs such as the brain (3),…

maximizing aesthetics, and improving the long-term success of the implants. Flapless implant surgery appears to be one way this can be aided.(reference) The flapless technique uses rotary burs or a tissue punch to gain access to bone without flap elevation, so the vascular supply and surrounding soft tissue are well preserved. The advantages of this type of procedure include less surgical trauma, decreased operative time, rapid postsurgical healing, fewer postoperative complications, and…

Cellular pathology studies body organs and tissues to determine the cause of certain diseases and their effects. A sample of tissue cells are taken from the patient and sent to the laboratory in order to give a diagnosis and give the most appropriate advice and treatment to patients. Cell pathology helps to assist with the choice of treatment that will be given, and giving prognosis and determining causes of death. There are two main parts within cellular pathology. The first is histopathology,…

These tissues produce neurotransmitters. It is specialised to respond to stimuli and to conduct impulses to different organs in the body. Nerve tissues are all composed of a particular nerve cell called neurons. It has three types’ neurones, which are sensory neuron, motor neuron and inter neurons. It conducts impulses to and from…
