Estimation Of Stature
Forensic estimation of stature is part of the identification process necessary when dismembered body parts are found. It is also possible to estimate the stature from bones. Even measurements of body parts of body such as a finger can be used to estimate the stature. The principle behind this forensic anthropology technique is the fact that for a given combination of age, race, and gender there measurements of different body parts which have a relationship to the stature. This relationship between the measurements of body parts was known to sculptors and artists. In modern times, regression formulae are used to estimate stature from bones, fragments of bones or measurements of body parts. History Vitruvius, who lived in the first century BC had put forth the proportions of human body in Book III, Chapter 1.. Leonardo da Vinci had based the proportions of the famous Vitruvian man on his writings. Modern Research In 1888 Rollet measured the stature and the lengths of the long b ...

Vitruvian
The ''Vitruvian Man'' ( it, L'uomo vitruviano; ) is a drawing by the Italian Renaissance artist and scientist Leonardo da Vinci, dated to . Inspired by the writings by the ancient Roman architect Vitruvius, the drawing depicts a nude man in two superimposed positions with his arms and legs apart and inscribed in both a circle and square. Described by the art historian Carmen C. Bambach as "justly ranked among the all-time iconic images of Western civilization," the work is a unique synthesis of artistic and scientific ideals and often considered an archetypal representation of the High Renaissance. The drawing represents Leonardo's conception of ideal body proportions, originally derived from Vitruvius but influenced by his own measurements, the drawings of his contemporaries, and the ''De pictura'' treatise by Leon Battista Alberti. Leonardo produced the ''Vitruvian Man'' in Milan and the work was probably passed to his student Francesco Melzi. It later came into the possession o ...

Male
Male (symbol: ♂) is the sex of an organism that produces the gamete (sex cell) known as sperm, which fuses with the larger female gamete, or ovum, in the process of fertilization. A male organism cannot reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs. Not all species share a common sex-determination system. In most animals, including humans, sex is determined genetically; however, species such as ''Cymothoa exigua'' change sex depending on the number of females present in the vicinity. In humans, the word ''male'' can also be used to refer to gender in the social sense of gender role or gender identity. Overview The existence of separate sexes has evolved independently at different times and in different lineages, an example ...

Ulna
The ulna (''pl''. ulnae or ulnas) is a long bone found in the forearm that stretches from the elbow to the smallest finger, and when in anatomical position, is found on the medial side of the forearm. That is, the ulna is on the same side of the forearm as the little finger. It runs parallel to the radius, the other long bone in the forearm. The ulna is usually slightly longer than the radius, but the radius is thicker. Therefore, the radius is considered to be the larger of the two. Structure The ulna is a long bone found in the forearm that stretches from the elbow to the smallest finger, and when in anatomical position, is found on the medial side of the forearm. It is broader close to the elbow, and narrows as it approaches the wrist. Close to the elbow, the ulna has a bony process, the olecranon process, a hook-like structure that fits into the olecranon fossa of the humerus. This prevents hyperextension and forms a hinge joint with the trochlea of the humerus. There is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mexicans
Mexicans ( es, mexicanos) are the citizens of the United Mexican States. The most spoken language by Mexicans is Spanish language, Spanish, but some may also speak languages from 68 different Languages of Mexico, Indigenous linguistic groups and other languages brought to Mexico by recent immigration or learned by Mexican expats residing in other countries. In 2015, 21.5% of Mexico's population Indigenous peoples of Mexico, self-identified as being Indigenous. There are about 12 million Mexican nationals residing outside Mexico, with about 11.7 million living in the United States. The larger Mexican diaspora can also include individuals that trace ancestry to Mexico and self-concept, self-identify as Mexican yet are not necessarily Mexican by citizenship, culture or language. The United States has the largest Mexican population after Mexico in the world at 37,186,361 (2019). The modern nation of Mexico achieved independence from the Spanish Empire in 1821, after a decade long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White People
White is a racialized classification of people and a skin color specifier, generally used for people of European origin, although the definition can vary depending on context, nationality, and point of view. Description of populations as "White" in reference to their skin color predates this notion and is occasionally found in Greco-Roman ethnography and other ancient or medieval sources, but these societies did not have any notion of a White or pan-European race. The term "White race" or "White people", defined by their light skin among other physical characteristics, entered the major European languages in the later seventeenth century, when the concept of a "unified White" achieve universal acceptance in Europe, in the context of racialized slavery and unequal social status in the European colonies. Scholarship on race distinguishes the modern concept from pre-modern descriptions, which focused on physical complexion rather than race. Prior to the modern era, no Europe ...

Radius (bone)
The radius or radial bone is one of the two large bones of the forearm, the other being the ulna. It extends from the lateral side of the elbow to the thumb side of the wrist and runs parallel to the ulna. The ulna is usually slightly longer than the radius, but the radius is thicker. Therefore the radius is considered to be the larger of the two. It is a long bone, prism-shaped and slightly curved longitudinally. The radius is part of two joints: the elbow and the wrist. At the elbow, it joins with the capitulum of the humerus, and in a separate region, with the ulna at the radial notch. At the wrist, the radius forms a joint with the ulna bone. The corresponding bone in the lower leg is the fibula. Structure The long narrow medullary cavity is enclosed in a strong wall of compact bone. It is thickest along the interosseous border and thinnest at the extremities, same over the cup-shaped articular surface (fovea) of the head. The trabeculae of the spongy tissue are some ...

Humerus
The humerus (; ) is a long bone in the arm that runs from the shoulder to the elbow. It connects the scapula and the two bones of the lower arm, the radius and ulna, and consists of three sections. The humeral upper extremity consists of a rounded head, a narrow neck, and two short processes (tubercles, sometimes called tuberosities). The body is cylindrical in its upper portion, and more prismatic below. The lower extremity consists of 2 epicondyles, 2 processes (trochlea & capitulum), and 3 fossae (radial fossa, coronoid fossa, and olecranon fossa). As well as its true anatomical neck, the constriction below the greater and lesser tubercles of the humerus is referred to as its surgical neck due to its tendency to fracture, thus often becoming the focus of surgeons. Etymology The word "humerus" is derived from la, humerus, umerus meaning upper arm, shoulder, and is linguistically related to Gothic ''ams'' shoulder and Greek ''ōmos''.

Tibia
The tibia (; ), also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two bones in the leg below the knee in vertebrates (the other being the fibula, behind and to the outside of the tibia); it connects the knee with the ankle. The tibia is found on the medial side of the leg next to the fibula and closer to the median plane. The tibia is connected to the fibula by the interosseous membrane of leg, forming a type of fibrous joint called a syndesmosis with very little movement. The tibia is named for the flute ''tibia''. It is the second largest bone in the human body, after the femur. The leg bones are the strongest long bones as they support the rest of the body. Structure In human anatomy, the tibia is the second largest bone next to the femur. As in other vertebrates the tibia is one of two bones in the lower leg, the other being the fibula, and is a component of the knee and ankle joints. The ossification or formation of the bone ...

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 ...

Female
Female (Venus symbol, symbol: ♀) is the sex of an organism that produces the large non-motile ovum, ova (egg cells), the type of gamete (sex cell) that fuses with the Sperm, male gamete during sexual reproduction. A female has larger gametes than a male. Females and males are results of the anisogamous reproduction system, wherein gametes are of different sizes, unlike isogamy where they are the same size. The exact mechanism of female gamete evolution remains unknown. In species that have males and females, Sex-determination system, sex-determination may be based on either sex chromosomes, or environmental conditions. Most female mammals, including female humans, have two X chromosomes. Female characteristics vary between different species with some species having pronounced Secondary sex characteristic, secondary female sex characteristics, such as the presence of pronounced mammary glands in mammals. In humans, the word ''female'' can also be used to refer to gender i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Puerto Ricans
Puerto Ricans ( es, Puertorriqueños; or boricuas) are the people of Puerto Rico, the inhabitants, and citizens of the Commonwealth of Puerto Rico and their descendants. Overview The culture held in common by most Puerto Ricans is referred to as a Western culture largely derived from the traditions of Spain, and more specifically Andalusia and the Canary Islands. Puerto Rico has also received immigration from other parts of Spain such as Catalonia as well as from other European countries such as France, Ireland, Italy and Germany. Puerto Rico has also been influenced by African culture, with many Puerto Ricans partially descended from Africans, though Afro-Puerto Ricans of unmixed African descent are only a significant minority. Also present in today's Puerto Ricans are traces (about 10-15%) of the aboriginal Taino natives that inhabited the island at the time of the European colonizers in 1493. Recent studies in population genetics have concluded that Puerto Rican gene poo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
