Fetal Position
Fetal position (British English: also foetal) is the positioning of the body of a prenatal fetus as it develops. In this position, the back is curved, the head is bowed, and the limbs are bent and drawn up to the torso. A compact position is typical for fetuses. Many newborn mammals, especially rodents, remain in a fetal position well after birth. This type of compact position is used in the medical profession to minimize injury to the neck and chest. Many people assume a compact position when sleeping, especially when the body becomes cold. Sometimes, when a person has suffered extreme physical or psychological trauma (including massive stress), they will assume a similar compact position in which the back is curved forward, the legs are brought up as tightly against the abdomen as possible, the head is bowed as close to the abdomen as possible, and the arms are wrapped around the head to prevent further trauma Trauma most often refers to: *Major trauma, in physical ...

Views Of A Foetus In The Womb
A view is a sight or prospect or the ability to see or be seen from a particular place. View, views or Views may also refer to: Common meanings * View (Buddhism), a charged interpretation of experience which intensely shapes and affects thought, sensation, and action * Graphical projection in a technical drawing or schematic ** Multiview orthographic projection, standardizing 2D images to represent a 3D object * Opinion, a belief about subjective matters * Page view, a visit to a World Wide Web page * Panorama, a wide-angle view * Scenic viewpoint, an elevated location where people can view scenery * World view, the fundamental cognitive orientation of an individual or society encompassing the entirety of the individual or society's knowledge and point-of-view Places * View, Kentucky, an unincorporated community in Crittenden County * View, Texas, an unincorporated community in Taylor County Arts, entertainment, and media Music * ''View'' (album), the 2003 debut album by ...

Psychological Trauma
Psychological trauma, mental trauma or psychotrauma is an emotional response to a distressing event or series of events, such as accidents, rape, or natural disasters. Reactions such as psychological shock and psychological denial are typical. Longer-term reactions include unpredictable emotions, flashbacks, difficulties with interpersonal relationships and sometimes physical symptoms including headaches or nausea. Trauma is not the same as mental distress or suffering, both of which are universal human experiences. Given that subjective experiences differ between individuals, people will react to similar events differently. In other words, not all people who experience a potentially traumatic event will actually become psychologically traumatized (although they may be distressed and experience suffering). Some people will develop post-traumatic stress disorder (PTSD) after being exposed to a major traumatic event (or series of events). This discrepancy in risk rate can be ...

Anatomy
Anatomy () is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science that deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated, both over immediate and long-term timescales. Anatomy and physiology, which study the structure and function of organisms and their parts respectively, make a natural pair of related disciplines, and are often studied together. Human anatomy is one of the essential basic sciences that are applied in medicine. The discipline of anatomy is divided into macroscopic and microscopic. Macroscopic anatomy, or gross anatomy, is the examination of an animal's body parts using unaided eyesight. Gross anatomy also includes the br ...

Position (obstetrics)
In obstetrics, position is the orientation of the fetus in the womb, identified by the location of the presenting part of the fetus relative to the pelvis of the mother. Conventionally, it is the position assumed by the fetus before the process of birth, as the fetus assumes various positions and postures during the course of childbirth. Positions Depending upon which part of the fetus is expected to be delivered first (fetal presentation), there are many possible positions: * Vertex presentation with longitudinal lie: * Breech presentation with longitudinal lie: #Left sacrum anterior (LSA)—the buttocks, as against the occiput of the vertex presentation, like close to the vagina (hence known as breech presentation), which lie anteriorly and towards the left. #Right sacrum anterior (RSA)—the buttocks face anteriorly and towards the right. #Left sacrum posterior (LSP)—the buttocks face posteriorly and towards the left. #Right sacrum posterior (RSP)—the ...

Neutral Body Posture
The neutral body posture (NBP) is the posture the human body naturally assumes in microgravity. Adopting any other posture while floating requires muscular effort. In the 1980s, NASA developed the Man-System Integration Standards (MSIS), a set of guidelines based on anthropometry and biomechanics, which included a definition of an average typical NBP created from measurements of crew members in the microgravity environment onboard Skylab. Still photographs taken on Skylab of crew members showed that in microgravity, the body assumed a distinguishable posture with the arms raised, the shoulder abducted, the knees flexed with noticeable hip flexion, and the foot plantar flexed. Later work by NASA based on research aboard Space Shuttle mission STS-57 found greater individual variations between crew members' neutral body positions than originally suggested by the earlier Skylab study. In general, three main postures were exhibited by the crew as a whole. These constituted (1) an almo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stephen Herrero
Stephen Herrero is a Canadian professor emeritus of ecology at the University of Calgary. He is the author of ''Bear Attacks: Their Causes and Avoidance'', which has been described as "authoritative" and "required reading" on the topic. Herrero was born in San Francisco, and earned his Ph.D. from University of California, Berkeley in animal behaviour and ecology. He moved to Canada after becoming disillusioned with overdevelopment in the U.S., and the Vietnam War. As a professor at the University of Calgary, Herrero's research on bear attacks has been highly influential; it helped develop new policies in bear safety and shifted focus to bear conservation. He is described as a leading authority on bear attacks and safety, produces bear safety videos, and testifies in legal proceedings involving bear attacks. He was a consultant on the 1978 National Film Board documentary, '' Bears and Man''. See also * Bear attack A bear attack is an attack by a bear on another animal, altho ...

Bear Attack
A bear attack is an attack by a bear on another animal, although it usually refers to a bear attacking a human or domestic pet such as a dog. Bear attacks are of particular concern for those who are in bear habitats. They can be fatal and often hikers, dogs, hunters, fishers, and others in bear country take precautions against bear attacks. Stephen Herrero, a Canadian biologist, reports that during the 1990s, bears killed around three people a year in the U.S. and Canada, as compared to the 30 to 50 people killed every year by dogs. Causes Almost all recorded bear attacks in the wild have resulted from the human surprising the bear. Hunters are the people most at risk of bear attacks because, as Tom Smith, a U.S. Geographical Survey research biologist, describes, "Hunters typically aren't making any noise, and they sleuth around while wearing camo."Batin, Christopher. ''Bear Attacks!'' p. 46 Hunters try to be silent and, though many hunters wear reflective clothing so as not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drug Addiction
Addiction is a neuropsychological disorder characterized by a persistent and intense urge to engage in certain behaviors, one of which is the usage of a drug, despite substantial harm and other negative consequences. Repetitive drug use often alters Brain#Function, brain function in ways that perpetuate Craving (withdrawal), craving, and weakens (but does not completely negate) self-control. This phenomenon – drugs Neuroplasticity, reshaping Human brain, brain function – has led to an understanding of addiction as a brain disorder with a complex variety of Social psychology, psychosocial as well as Neuroscience, neurobiological (and thus involuntary) factors that are implicated in addiction's development. Classic signs of addiction include Compulsive behavior, compulsive engagement in Reward system, rewarding stimuli, ''preoccupation'' with substances or behavior, and continued use despite negative consequences. Habits and patterns associated with addiction are typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physical Trauma
An injury is any physiological damage to living tissue caused by immediate physical stress. An injury can occur intentionally or unintentionally and may be caused by blunt trauma, penetrating trauma, burning, toxic exposure, asphyxiation, or overexertion. Injuries can occur in any part of the body, and different symptoms are associated with different injuries. Treatment of a major injury is typically carried out by a health professional and varies greatly depending on the nature of the injury. Traffic collisions are the most common cause of accidental injury and injury-related death among humans. Injuries are distinct from chronic conditions, psychological trauma, infections, or medical procedures, though injury can be a contributing factor to any of these. Several major health organizations have established systems for the classification and description of human injuries. Occurrence Injuries may be intentional or unintentional. Intentional injuries may be acts of vio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stress (medicine)
Stress, either physiological, biological or psychological, is an organism's response to a stressor such as an environmental condition. Stress is the body's method of reacting to a condition such as a threat, challenge or physical and psychological barrier. There are two hormones that an individual produces during a stressful situation, these are well known as adrenaline and cortisol. There are two kinds of stress hormone levels. Resting (basal) cortisol levels are normal everyday quantities that are essential for standard functioning. Reactive cortisol levels are increases in cortisol in response to stressors. Stimuli that alter an organism's environment are responded to by multiple systems in the body. In humans and most mammals, the autonomic nervous system and hypothalamic-pituitary-adrenal (HPA) axis are the two major systems that respond to stress. The sympathoadrenal medullary (SAM) axis may activate the fight-or-flight response through the sympathetic nervous s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

British English
British English (BrE, en-GB, or BE) is, according to Lexico, Oxford Dictionaries, "English language, English as used in Great Britain, as distinct from that used elsewhere". More narrowly, it can refer specifically to the English language in England, or, more broadly, to the collective dialects of English throughout the British Isles taken as a single umbrella variety, for instance additionally incorporating Scottish English, Welsh English, and Ulster English, Northern Irish English. Tom McArthur (linguist), Tom McArthur in the ''Oxford Guide to World English'' acknowledges that British English shares "all the ambiguities and tensions [with] the word 'British people, British' and as a result can be used and interpreted in two ways, more broadly or more narrowly, within a range of blurring and ambiguity". Variations exist in formal (both written and spoken) English in the United Kingdom. For example, the adjective ''wee'' is almost exclusively used in parts of Scotland, North E ...
