The superior gluteal artery (gluteal artery) is the largest branch of the internal iliac artery, and appears to be the continuation of the posterior division of that vessel.

It is a short artery which runs backward between the lumbosacral trunk and the first sacral nerve, and, passing out of the pelvis above the upper border of the Piriformis, immediately divides into a superficial and a deep branch.

The palatoglossus is the only muscle of the tongue that is not innervated by the hypoglossal nerve (CN XII). It is innervated by the Vagus nerve (CN X)

Along with the other three muscles of mastication (temporalis, medial pterygoid and lateral pterygoid), the masseter is innervated by the mandibular division of the trigeminal nerve.



The vast majority of ectopic pregnancies implant in the Fallopian tube. Pregnancies can grow in the fimbrial end (5% of all ectopics), the ampullary section (80%), the isthmus (12%), and the cornual and interstitial part of the tube (2%)


NOTE : MOST COMMON SIT E IS AT THE AMPULLARY SECTION

As an antifungal, ketoconazole is structurally similar to imidazole and interferes with the fungal synthesis of ergosterol, a constituent of fungalcell membranes, as well as certain enzymes.

Pneumocystis pneumonia (PCP) or pneumocystosis is a form of pneumonia, caused by the yeast-like fungus (which had previously been erroneously classified as a protozoan) Pneumocystis jirovecii.

A number of different flatworm parasites in the family Schistosomatidae are what cause swimmer’s itch.



Naegleria fowleri (pronounced /nəˈɡlɪəriə/, also known as "the brain-eating amoeba") is a free-living excavate form of protist typically found in warm bodies of fresh water, such as ponds, lakes, rivers, and hot springs. It is also found in soil, near warm water discharges of industrial plants, and minimally chlorinated swimming pools (there is no evidence of this organism living in ocean water) in an amoeboid or temporary flagellate stage. It belongs to a group called the Percolozoa or Heterolobosea. Although not a true amoeba, the organism is often referred to as an amoeba for convenience.

Ketone bodies are three water-soluble compounds that are produced as by-products when fatty acids are broken down for energy in the liver and kidney. They are used as a source of energy in the heart and brain.


NOTE FATTY ACID, NOT THE GLUCOSE


Production

Ketone bodies are produced from acetyl-CoA (see ketogenesis) mainly in the mitochondrial matrix of hepatocytes when carbohydrates are so scarce that energy must be obtained from breaking down fatty acids. Because of the high level of acetyl CoA present in the cell, the pyruvate dehydrogenase complex is inhibited, whereas pyruvate carboxylase becomes activated. Thus, the oxaloacetate produced will entergluconeogenesis rather than the citric acid cycle, as the latter is also inhibited by the elevated level of NADH resulting from ß-oxidation of fatty acids. The excess acetyl-CoA is therefore rerouted to ketogenesis. Such a state in humans is referred to as the fasted state.

Acetone is produced by spontaneous decarboxylation of acetoacetate, yielding levels of acetone much lower than those of other ketone bodies. Acetone cannot be converted back to acetyl-CoA; it is instead metabolized (e.g., converted to glucose via pyruvate[5]), excreted in theurine, or (as a consequence of its high vapor pressure) exhaled. Acetone is responsible for the characteristic "fruity" odor of the breath of
