Stabbed
A stabbing is penetration or rough contact with a sharp or pointed object at close range. ''Stab'' connotes purposeful action, as by an assassin or murderer, but it is also possible to accidentally stab oneself or others. Stabbing differs from slashing or cutting in that the motion of the object used in a stabbing generally moves perpendicular to and directly into the victim's body, rather than being drawn across it. Stabbings today are common among gangs and in prisons because knives are cheap, easy to acquire (or manufacture), easily concealable and relatively effective. In 2013, about 8 million stabbings occurred. History Stabbings have been common throughout human history and were the means used to assassinate a number of distinguished historical figures, such as Second Caliph Umar and Roman dictator Julius Caesar and emperor Caligula. In Japan, the historical practice of stabbing oneself deliberately in ritual suicide is known as ''seppuku'' (more colloquially ''har ...

Julius Caesar
Gaius Julius Caesar (; ; 12 July 100 BC – 15 March 44 BC), was a Roman general and statesman. A member of the First Triumvirate, Caesar led the Roman armies in the Gallic Wars before defeating his political rival Pompey in a civil war, and subsequently became dictator from 49 BC until his assassination in 44 BC. He played a critical role in the events that led to the demise of the Roman Republic and the rise of the Roman Empire. In 60 BC, Caesar, Crassus and Pompey formed the First Triumvirate, an informal political alliance that dominated Roman politics for several years. Their attempts to amass power as were opposed by the within the Roman Senate, among them Cato the Younger with the frequent support of Cicero. Caesar rose to become one of the most powerful politicians in the Roman Republic through a string of military victories in the Gallic Wars, completed by 51 BC, which greatly extended Roman territory. During this time he both invaded Britain an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Umar
ʿUmar ibn al-Khaṭṭāb ( ar, عمر بن الخطاب, also spelled Omar, ) was the second Rashidun caliph, ruling from August 634 until his assassination in 644. He succeeded Abu Bakr () as the second caliph of the Rashidun Caliphate on 23 August 634. Umar was a senior companion and father-in-law of the Islamic prophet Muhammad. He was also an expert Muslim jurist known for his pious and just nature, which earned him the epithet ''al-Fārūq'' ("the one who distinguishes (between right and wrong)"). Umar initially opposed Muhammad, his distant Qurayshite kinsman and later son-in-law. Following his conversion to Islam in 616, he became the first Muslim to openly pray at the Kaaba. Umar participated in almost all battles and expeditions under Muhammad, who bestowed the title ''al-Fārūq'' ('the Distinguisher') upon Umar, for his judgements. After Muhammad's death in June 632, Umar pledged allegiance to Abu Bakr () as the first caliph and served as the closest advis ...

Caligula
Gaius Julius Caesar Augustus Germanicus (31 August 12 – 24 January 41), better known by his nickname Caligula (), was the third Roman emperor, ruling from 37 until his assassination in 41. He was the son of the popular Roman general Germanicus and Augustus' granddaughter Agrippina the Elder. Caligula was born into the first ruling family of the Roman Empire, conventionally known as the Julio-Claudian dynasty. Although Gaius was named after Gaius Julius Caesar, he acquired the nickname "Caligula" ("little ''caliga''," a type of military boot) from his father's soldiers during their campaign in Germania. When Germanicus died at Antioch in 19, Agrippina returned with her six children to Rome, where she became entangled in a bitter feud with Tiberius. The conflict eventually led to the destruction of her family, with Caligula as the sole male survivor. In 26, Tiberius withdrew from public life to the island of Capri, and in 31, Caligula joined him there. Following the death of ...

Seppuku
, sometimes referred to as hara-kiri (, , a native Japanese kun reading), is a form of Japanese ritual suicide by disembowelment. It was originally reserved for samurai in their code of honour but was also practised by other Japanese people during the Shōwa period (particularly officers near the end of World War II) to restore honour for themselves or for their families. As a samurai practice, ''seppuku'' was used voluntarily by samurai to die with honour rather than fall into the hands of their enemies (and likely be tortured), as a form of capital punishment for samurai who had committed serious offences, or performed because they had brought shame to themselves. The ceremonial disembowelment, which is usually part of a more elaborate ritual and performed in front of spectators, consists of plunging a short blade, traditionally a '' tantō'', into the belly and drawing the blade from left to right, slicing the belly open. If the cut is deep enough, it can sever the abdomin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abrasion (medical)
An abrasion is a partial thickness wound caused by damage to the skin and can be superficial involving only the epidermis to deep, involving the deep dermis. Abrasions usually involve minimal bleeding.McCurnin, D.M. & Bassert, J. M. (2010) Clinical Textbook for Veterinary Technicians. 7th Edition. St. Louis, MO: Saunders Elsevier. pg 1243-1244 Mild abrasions, also known as ''grazes'' or ''scrapes'', do not scar or bleed because the dermis is left intact, but deep abrasions that disrupt the normal dermal structures may lead to the formation of scar tissue. A more traumatic abrasion that removes all layers of skin is called an avulsion. Abrasion injuries most commonly occur when exposed skin comes into moving contact with a rough surface, causing a grinding or rubbing away of the upper layers of the epidermis. By degree * A first-degree abrasion involves only epidermal injury. * A second-degree abrasion involves the epidermis as well as the dermis and may bleed slightly. * A th ...

Bruise
A bruise, also known as a contusion, is a type of hematoma of tissue, the most common cause being capillaries damaged by trauma, causing localized bleeding that extravasates into the surrounding interstitial tissues. Most bruises occur close enough to the epidermis such that the bleeding causes a visible discoloration. The bruise then remains visible until the blood is either absorbed by tissues or cleared by immune system action. Bruises which do not blanch under pressure can involve capillaries at the level of skin, subcutaneous tissue, muscle, or bone. Bruises are not to be confused with other similar-looking lesions. (Such lesions include petechia (less than , resulting from numerous and diverse etiologies such as adverse reactions from medications such as warfarin, straining, asphyxiation, platelet disorders and diseases such as ''cytomegalovirus''), purpura (, classified as palpable purpura or non-palpable purpura and indicates various pathologic conditions such as thr ...

Forensic Pathologist
Forensic pathology is pathology that focuses on determining the cause of death by examining a corpse. A post mortem examination is performed by a medical examiner or forensic pathologist, usually during the investigation of criminal law cases and civil law cases in some jurisdictions. Coroners and medical examiners are also frequently asked to confirm the identity of remains. Duties Forensic pathology is an application of medical jurisprudence. A forensic pathologist is a medical doctor who has completed training in anatomical pathology and has subsequently specialized in forensic pathology. The requirements for becoming a "fully qualified" forensic pathologist vary from country to country. Some of the different requirements are discussed below. The forensic pathologist performs autopsies/postmortem examinations with the goal determining the cause of death as well as the possible manner of death. The autopsy report contains conclusions made relating to the following: * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laparotomy
A laparotomy is a surgical procedure involving a surgical incision through the abdominal wall to gain access into the abdominal cavity. It is also known as a celiotomy. Origins and history The first successful laparotomy was performed without anesthesia by Ephraim McDowell in 1809 in Danville, Kentucky. On July 13, 1881, George E. Goodfellow treated a miner outside Tombstone, Arizona Territory, who had been shot in the abdomen with a .32-caliber Colt revolver. Goodfellow was able to operate on the man nine days after he was shot, when he performed the first laparotomy to treat a bullet wound. Terminology The term comes from the Greek word λᾰπάρᾱ (lapara) 'the soft part of the body between the ribs and hip, flank' and the suffix ''-tomy'', from the Greek word τομή (tome) '(surgical) cut'. In diagnostic laparotomy (most often referred to as an exploratory laparotomy and abbreviated ex-lap), the nature of the disease is unknown, and laparotomy is deemed the best way ...

Lung
The lungs are the primary organs of the respiratory system in humans and most other animals, including some snails and a small number of fish. In mammals and most other vertebrates, two lungs are located near the backbone on either side of the heart. Their function in the respiratory system is to extract oxygen from the air and transfer it into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere, in a process of gas exchange. Respiration is driven by different muscular systems in different species. Mammals, reptiles and birds use their different muscles to support and foster breathing. In earlier tetrapods, air was driven into the lungs by the pharyngeal muscles via buccal pumping, a mechanism still seen in amphibians. In humans, the main muscle of respiration that drives breathing is the diaphragm. The lungs also provide airflow that makes vocal sounds including human speech possible. Humans have two lungs, one on the left an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heart
The heart is a muscular organ in most animals. This organ pumps blood through the blood vessels of the circulatory system. The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs. In humans, the heart is approximately the size of a closed fist and is located between the lungs, in the middle compartment of the chest. In humans, other mammals, and birds, the heart is divided into four chambers: upper left and right atria and lower left and right ventricles. Commonly the right atrium and ventricle are referred together as the right heart and their left counterparts as the left heart. Fish, in contrast, have two chambers, an atrium and a ventricle, while most reptiles have three chambers. In a healthy heart blood flows one way through the heart due to heart valves, which prevent backflow. The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of fluid. The wall of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blood Loss
Bleeding, hemorrhage, haemorrhage or blood loss, is blood escaping from the circulatory system from damaged blood vessels. Bleeding can occur internally, or externally either through a natural opening such as the mouth, nose, ear, urethra, vagina or anus, or through a puncture in the skin. Hypovolemia is a massive decrease in blood volume, and death by excessive loss of blood is referred to as exsanguination. Typically, a healthy person can endure a loss of 10–15% of the total blood volume without serious medical difficulties (by comparison, blood donation typically takes 8–10% of the donor's blood volume). The stopping or controlling of bleeding is called hemostasis and is an important part of both first aid and surgery. Types * Upper head ** Intracranial hemorrhage – bleeding in the skull. ** Cerebral hemorrhage – a type of intracranial hemorrhage, bleeding within the brain tissue itself. ** Intracerebral hemorrhage – bleeding in the brain caused by the rup ...

Shock (circulatory)
Shock is the state of insufficient blood flow to the tissues of the body as a result of problems with the circulatory system. Initial symptoms of shock may include weakness, fast heart rate, fast breathing, sweating, anxiety, and increased thirst. This may be followed by confusion, unconsciousness, or cardiac arrest, as complications worsen. Shock is divided into four main types based on the underlying cause: low volume, cardiogenic, obstructive, and distributive shock. Low volume shock, also known as hypovolemic shock, may be from bleeding, diarrhea, or vomiting. Cardiogenic shock may be due to a heart attack or cardiac contusion. Obstructive shock may be due to cardiac tamponade or a tension pneumothorax. Distributive shock may be due to sepsis, anaphylaxis, injury to the upper spinal cord, or certain overdoses. The diagnosis is generally based on a combination of symptoms, physical examination, and laboratory tests. A decreased pulse pressure (systolic blood press ...
