What is crenate? Crenation is the loss of water from an animal cell due to osmosis. Lysis is the rupture of the cell wall due to too much water moving into an animal cell due to osmosis. Both …crenation and lysis have drastic effects on the animal cell.

Cri Du Chat Syndrome The cause of cri du chat syndrome is thought to be due to a mutation or missing segment of a particular chromosome, called chromosome 5. A very small percentage of affected children have received the mutation from a parent, but most cases of this disorder are random and occur during development of the egg or sperm.

- Menstrual Cramps Causes. Primary dysmenorrhea (painful menstruation) occurs in the absence of any anatomic abnormalities or causes for the pain. This type of painful menstruation is most often seen in young women in the years following the onset of menstruation. Secondary dysmenorrhea refers to painful menstrual cramps that occur as the result of another medical condition such as endometriosis.

PANCE Practice Exam #2 This develops from months or years of exposure to small amounts of lead in the environment. Iron deficiency anemia. This occurs when low iron levels cause a low amount of oxygen-carrying hemoglobin in red blood cells. The iron levels are low, the transferrin saturation is high, and the ferritin level is low.

What causes a crevasse on glaciers? A quick or sharp movement from the glacier could cause the crevasse. Fast increases in temperature or the overall global warming can cause the glaciers to form crevasses as well. Also in some cases water flows can cause or deepen crevasses.

Blood Clot Prevention The leading cause of stroke occurs when a blood clot occludes, or obstructs, an artery supplying blood to your brain. Formation of vascular blood clots is also a leading cause of death in cancer patients because cancer cells create conditions that favor clotting.he leading cause of stroke occurs when a blood clot occludes, or obstructs, an artery supplying blood to your brain.

- As discussed in Formation of Lacunes, the cause of lacunar infarction is occlusion of a single small penetrating artery. This occlusion may be due to microatheroma and lipohyalinosis, which are associated with hypertension, smoking, and diabetes, or may result from microembolism from the heart or carotid arteries.he lacunar hypothesis proposes that (1) symptomatic lacunes present with distinctive lacunar syndromes and (2) a lacune is due to occlusion of a single, deep penetrating artery generated by a specific vascular pathology. The above concept is controversial, because different definitions of lacunes have been used.

- Constipation may cause faeces to pack the intestine and rectum so tightly that the normal pushing action fails and the colon is not strong enough to expel the stool. This is called faecal impaction. Accidental loss of faeces, i.e. faecal incontinence can occur in those with constipation when the bowel becomes too full. Haemorrhoids can be caused by straining to have a bowel movement. Anal fissures (tears in skin around anus) are caused when a hard stool stretches the sphincter muscle. In extreme cases straining can cause a small amount of intestinal lining to push out from the anal opening causing a rectal prolapse.

Cavitation It usually occurs when a liquid is subjected to rapid changes of pressure that cause the formation of cavities where the pressure is relatively low. When subjected to higher pressure, the voids implode and can generate an intense shock wave. Cavitation is a significant cause of wear in some engineering contexts. Collapsing voids that implode near to a metal surface cause cyclic stress through repeated implosion. This results in surface fatigue of the metal causing a type of wear also called cavitation.

What is crenate? Crenation is the contraction of a cell after exposure to a hypertonic solution, due to the loss of water through osmosis. Hemolysis is the breakdown of red blood cells.

Stroke There are four reasons why this might happen: 1  Thrombosis (obstruction of a blood vessel by a blood clot forming locally) 2  Embolism (obstruction due to an embolus from elsewhere in the body, see below), 3  Systemic hypoperfusion (general decrease in blood supply, e.g., in shock) 4  cerebral venous sinus thrombosis.

Understand Your Risk for Excessive Blood Clotting Certain diseases and conditions are more likely to cause clots to form in specific areas of the body. Conditions that can trigger excessive blood clotting in the heart and brain: 1  Atherosclerosis is a disease in which a waxy substance called plaque builds up inside your arteries.2  Over time, the plaque may rupture. 3  Platelets clump together to form clots at the site of the damage.any factors can lead to excessive blood clotting, leading to limited or blocked blood flow. Blood clots can travel to the arteries or veins in the brain, heart, kidneys, lungs and limbs, which in turn can cause heart attack, stroke, damage to the body’s organs or even death. 1  Smoking. 2  Overweight and obesity.

Amenorrhea Primary amenorrhoea can be diagnosed in women by age 14 if no secondary sex characteristics, such as enlarged breasts and body hair, are present. In the absence of secondary sex characteristics, the most common cause of amenorrhoea is low levels of FSH and LH caused by a delay in puberty.rimary amenorrhoea can be diagnosed in women by age 14 if no secondary sex characteristics, such as enlarged breasts and body hair, are present.

Overview Problems with the sexual organs themselves also can cause amenorrhea. Examples include: Uterine scarring. Asherman's syndrome, a condition in which scar tissue builds up in the lining of the uterus, can sometimes occur after a dilation and curettage (D&C), cesarean section or treatment for uterine fibroids.

- Causes [edit]. The most common cause of melena is peptic ulcer disease. Any other cause of bleeding from the upper gastrointestinal tract, or even the ascending colon, can also cause melena. Melena may also be a sign of drug overdose if a patient is taking anticoagulants, such as warfarin.

Spontaneous cervical-mediastinal hematoma caused by hemorrhage into parathyroid adenoma: A clinical case Spontaneous cervical-mediastinal hematoma caused by extracapsular rupture of parathyroid gland occurs extremely rarely. The first occasion of an spontaneous cervical-mediastinal hematoma caused by hemorrhage into parathyroid adenoma was determined during autopsy.1 It indicates the extreme hazard of this condition. There were 28 reports of individual clinical observations in the PubMed databases until 2009.

- Cramps occur when the muscles of the uterus contract to expel the lining, which is made of tiny blood vessels. A substance called prostaglandin triggers the contraction of the uterine muscles, which can cause menstrual cramps. These may be felt as a throbbing or dull pain in the lower abdomen.

A to Z List of Neurological Disorders Other causes include conditions that involve increased cranial pressure, such as: Brain hemorrhage or bleeding: This occurs when injury, disease, congenital disabilities, or blood vessels in the brain rupture, causing blood to accumulate and put pressure on brain tissues. Hydrocephalus: Congenital disability, injury, or disease cause cerebral spinal fluid (CSF) to accumulate, putting pressure on the brain. Subarachnoid hemorrhage: This happens when bleeding occurs between the brain and the tissues surrounding it.

Overview Hyperparathyroidism is caused by factors that increase the production of parathyroid hormone. The parathyroid glands maintain proper levels of both calcium and phosphorus in your body by turning the secretion of parathyroid hormone (PTH) off or on, much like a thermostat controls a heating system to maintain a constant air temperature.
