Pacatnamu
The Pacatnamu ( Mochica : ''Pakatnamú'', Spanish : ''Pacatnamú'') site is located at the mouth of the Jequetepeque Valley on the northern coast of Peru. Rocky cliffs protect two of its sides and a manmade wall protects the third. This area of Peru does not have a tropical environment; it gets very little precipitation and has a mild climate, which sometime can become very humid. Excavation history Explorers had mentioned the site of Pacatnamu since the late 1800s, but the site was not studied in detail until 1925. Kroeber made some sketches of the main architectural features of the site but only of one portion of the site. Archaeological excavations first began in 1937–39 by German archaeologist, Ubbelohde-Doering. He conducted more excavations in 1952–53 and again in 1962–63. His work resulted in more excavations of more pyramid complexes. Wolfgang and Giesela Hecker joined Ubbelohde-Doering on his 1962–63 excavations. They produced a general map of the site as ...

Chimu
Chimor (also Kingdom of Chimor or Chimú Empire) was the political grouping of the Chimú culture. The culture arose about 900 AD, succeeding the Moche culture, and was later conquered by the Inca emperor Topa Inca Yupanqui around 1470, fifty years before the arrival of the Spanish in the region. Chimor () was the largest kingdom in the Late Intermediate Period, encompassing 1,000 kilometres (620 mi) of coastline. The Chimor dynasty begins with two origin myths about the Naymlap dynasty that were orally passed down and conserved. The first legend begins with the arrival of Taycanamo in the Moche Valley after he crossed an unknown sea on a balsa raft. From there his descendants would conquer surrounding areas starting with his son Guacricaur. Guacricaur integrated Chimú reign over the lower valley and Ñançenpinco, Taycanamo's grandson would expand the kingdom by conquering the upper valley. Ñançenpinco began to further expansion both north and south of the Moche Va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moche (culture)
The Moche civilization (; alternatively, the Mochica culture or the Early, Pre- or Proto-Chimú) flourished in northern Peru with its capital near present-day Moche, Trujillo, Peru from about 100 to 700 AD during the Regional Development Epoch. While this issue is the subject of some debate, many scholars contend that the Moche were not politically organized as a monolithic empire or state. Rather, they were likely a group of autonomous polities that shared a common culture, as seen in the rich iconography and monumental architecture that survives today. Background Moche society was agriculturally based, with a significant level of investment in the construction of a sophisticated network of irrigation canals for the diversion of river water to supply their crops. Their artifacts express their lives, with detailed scenes of hunting, fishing, fighting, sacrifice, sexual encounters, and elaborate ceremonies. The Moche are particularly noted for their elaborately painted ceramic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Femur
The femur (; ), or thigh bone, is the proximal bone of the hindlimb in tetrapod vertebrates. The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates with the tibia (shinbone) and patella (kneecap), forming the knee joint. By most measures the two (left and right) femurs are the strongest bones of the body, and in humans, the largest and thickest. Structure The femur is the only bone in the upper leg. The two femurs converge medially toward the knees, where they articulate with the proximal ends of the tibiae. The angle of convergence of the femora is a major factor in determining the femoral-tibial angle. Human females have thicker pelvic bones, causing their femora to converge more than in males. In the condition ''genu valgum'' (knock knee) the femurs converge so much that the knees touch one another. The opposite extreme is ''genu varum'' (bow-leggedness). In the general populatio ...

Cartilaginous
Cartilage is a resilient and smooth type of connective tissue. In tetrapods, it covers and protects the ends of long bones at the joints as articular cartilage, and is a structural component of many body parts including the rib cage, the neck and the bronchial tubes, and the intervertebral discs. In other taxa, such as chondrichthyans, but also in cyclostomes, it may constitute a much greater proportion of the skeleton. It is not as hard and rigid as bone, but it is much stiffer and much less flexible than muscle. The matrix of cartilage is made up of glycosaminoglycans, proteoglycans, collagen fibers and, sometimes, elastin. Because of its rigidity, cartilage often serves the purpose of holding tubes open in the body. Examples include the rings of the trachea, such as the cricoid cartilage and carina. Cartilage is composed of specialized cells called chondrocytes that produce a large amount of collagenous extracellular matrix, abundant ground substance that is rich in proteoglyc ...

Dental Pathology
Tooth pathology is any condition of the tooth, teeth that can be congenital or acquired. Sometimes a congenital tooth diseases are called ''tooth abnormalities''. These are among the most common diseases in humans The preventive medicine, prevention, diagnosis, treatment and rehabilitation of these diseases are the base to the dentistry profession, in which are dentists and dental hygienists, and its sub-Specialty (medicine), specialties, such as oral medicine, oral and maxillofacial surgery, and endodontics. Tooth pathology is usually separated from other types of dental issues, including enamel hypoplasia and tooth wear. Examples Congenital * Anodontia Acquired * Dental caries—Dental caries are known as cavities or tooth decay Oral ecology, Bacteria in the mouth use foods that contain sugar or starch to produce acids which eat away at the tooth’s structure causing destruction to the Tooth enamel, enamel of the teeth. Meanwhile, the minerals in saliva (calcium and phosphate) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rheumatoid Arthritis
Rheumatoid arthritis (RA) is a long-term autoimmune disorder that primarily affects joints. It typically results in warm, swollen, and painful joints. Pain and stiffness often worsen following rest. Most commonly, the wrist and hands are involved, with the same joints typically involved on both sides of the body. The disease may also affect other parts of the body, including skin, eyes, lungs, heart, nerves and blood. This may result in a low red blood cell count, inflammation around the lungs, and inflammation around the heart. Fever and low energy may also be present. Often, symptoms come on gradually over weeks to months. While the cause of rheumatoid arthritis is not clear, it is believed to involve a combination of genetic and environmental factors. The underlying mechanism involves the body's immune system attacking the joints. This results in inflammation and thickening of the joint capsule. It also affects the underlying bone and cartilage. The diagnosis is made mos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ponchos
A poncho (; qu, punchu; arn, pontro; "blanket", "woolen fabric") is an outer garment designed to keep the body warm. A rain poncho is made from a watertight material designed to keep the body dry from the rain. Ponchos have been used by the Native American peoples of the Andes, Valley of Mexico and Patagonia since pre-Hispanic times, from places now under the territory of Mexico, Ecuador, Colombia, Chile, Bolivia, Peru, and Argentina and are now considered typical American garments. Types In its simplest form, the poncho is essentially a single large sheet of fabric with an opening in the center for the head. It often has an extra piece of fabric serving as a hood. Rainproof ponchos are normally fitted with fasteners to close the sides once the poncho is draped over the body, with openings provided for the arms. Many ponchos have hoods attached to ward off wind and rain. Alternative ponchos are now designed as fashion items. They are the same shape but of different materi ...

Chondroma
A chondroma is a benign cartilaginous tumor, which is encapsulated with a lobular growing pattern. Tumor cells (chondrocytes, cartilaginous cells) resemble normal cells and produce the cartilaginous matrix (amorphous, basophilic material). Presentation Characteristic features of this tumor include the vascular axes within the tumor, which make the distinction with normal hyaline cartilage. Diagnosis Classification Based upon location, a chondroma can be described as an enchondroma or ecchondroma. * enchondroma - tumor grows within the bone and expands it * ecchondroma - grows outward from the bone (rare) Treatment - best left alone - if it causes fractures (enchondroma) or is unsightly it should be removed by curettage and the defect filled with bone graft. See also * Extraskeletal chondroma Extraskeletal chondroma is a cutaneous condition, a rare benign tumor of mature cartilage. See also * List of cutaneous conditions Many skin conditions affect the human integ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Osteoarthritis
Osteoarthritis (OA) is a type of degenerative joint disease that results from breakdown of joint cartilage and underlying bone which affects 1 in 7 adults in the United States. It is believed to be the fourth leading cause of disability in the world. The most common symptoms are joint pain and stiffness. Usually the symptoms progress slowly over years. Initially they may occur only after exercise but can become constant over time. Other symptoms may include joint swelling, decreased range of motion, and, when the back is affected, weakness or numbness of the arms and legs. The most commonly involved joints are the two near the ends of the fingers and the joint at the base of the thumbs; the knee and hip joints; and the joints of the neck and lower back. Joints on one side of the body are often more affected than those on the other. The symptoms can interfere with work and normal daily activities. Unlike some other types of arthritis, only the joints, not internal organs, are af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guinea Pig
The guinea pig or domestic guinea pig (''Cavia porcellus''), also known as the cavy or domestic cavy (), is a species of rodent belonging to the genus ''Cavia'' in the family Caviidae. Breeders tend to use the word ''cavy'' to describe the animal, while in scientific and laboratory contexts, it is far more commonly referred to by the common name ''guinea pig''. Despite their common name, guinea pigs are not native to Guinea, nor are they closely related biologically to pigs, and the origin of the name is still unclear. They originated in the Andes of South America. Studies based on biochemistry and hybridization suggest they are domesticated animals that do not exist naturally in the wild, descendants of a closely related cavy species such as '' C. tschudii''. They were originally domesticated as livestock for a source of meat, and are still consumed in some parts of the world. In Western society, the guinea pig has enjoyed widespread popularity as a pet since its introducti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
