Strangulation
Strangling or strangulation is compression of the neck that may lead to unconsciousness or death by causing an increasingly hypoxic state in the brain by restricting the flow of oxygen through the trachea. Fatal strangulation typically occurs in cases of violence, accidents, and is one of two main ways that hanging causes death (alongside breaking the victim's neck). Strangling does not have to be fatal; limited or interrupted strangling is practised in erotic asphyxia, in the choking game, and is an important technique in many combat sports and self-defense systems. Strangling can be divided into three general types according to the mechanism used: * Hanging — Suspension from a cord wound around the neck * Ligature strangulation — Strangulation without suspension using some form of cord-like object ( ligature) called a garrote * Manual strangulation — Strangulation using the fingers, hands, or other extremity General Strangling involves one or several mechanisms that ...

Hanging
Hanging is killing a person by suspending them from the neck with a noose or ligature strangulation, ligature. Hanging has been a standard method of capital punishment since the Middle Ages, and has been the primary execution method in numerous countries and regions. The first known account of execution by hanging is in Homer's ''Odyssey''. Hanging is also a Suicide by hanging, method of suicide. Methods of judicial hanging There are numerous methods of hanging in execution that instigate death either by cervical fracture or by Strangling, strangulation. Short drop The short drop is a method of hanging in which the condemned prisoner stands on a raised support, such as a stool, ladder, cart, horse, or other vehicle, with the noose around the neck. The support is then moved away, leaving the person dangling from the rope. Suspended by the neck, the weight of the body tightens the noose around the neck, effecting strangulation and death. Loss of consciousness is typically rapid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Choking Game
The choking game, or fainting game, also sometimes referred to as Space Monkeys, is the act of intentionally cutting off oxygen to the brain with the goal of inducing temporary Syncope (medicine), loss of consciousness and euphoria. A related internet challenge, the blackout challenge, encourages the use of the choking game online. Reasons for practice Limited research has been conducted regarding motivations for practicing the fainting game, although thrill seeking has been identified as a risk factor, as has the perception that it is a low-risk activity. Anecdotal reasons stated include: * Peer pressure, a challenge or dare, a rite of passage into a social group or amusement over erratic behavior. * Curiosity in experiencing an altered state of consciousness, the experience of a greyout, or an imagined approximation to a near-death experience. * A belief that it can induce a brief sense of euphoria (a rushing sensation or altered state of consciousness, high). * The prospect of ...

Erotic Asphyxiation
Erotic asphyxiation (variously called asphyxiophilia, hypoxyphilia or breath control play) is the intentional restriction of oxygen to the brain for the purposes of sexual arousal. With a partner (or alone), the act often involves strangulation. The term autoerotic asphyxiation is used when the act is done by a person to themself. Colloquially, a person engaging in the activity is sometimes called a ''gasper''. Erotic asphyxiation can lead to accidental death due to asphyxia. The erotic interest in asphyxiation is classified as a paraphilia in the ''Diagnostic and Statistical Manual'' of the American Psychiatric Association. Physiology Concerning hallucinogenic states brought about by chronic hypoxia, Dr. E. L. Lloyd notes that they may be similar to the hallucinations experienced by climbers at altitude. He further notes that no such state occurs in hypoxia brought about by sudden aircraft decompression at altitude. These findings suggest to him that they do not arrive pure ...

Garrote
A garrote ( ; alternatively spelled as garotte and similar variants)''Oxford English Dictionary'', 11th Ed: garrotte is normal British English spelling, with single r alternate. Article title is US English spelling variant. or garrote vil () is a weapon and a method of capital punishment. It consists of a handheld (or, in later years, sometimes mechanical) ligature of chain, rope, scarf, wire, or fishing line, used to strangle a person.Newquist, H.P. and Maloof, Rich, ''This Will Kill You: A Guide to the Ways in Which We Go'', New York: St. Martin's Press, (2009), pp. 133-6 Assassination weapon A garrote can be made of different materials, including ropes, cloth, cable ties, fishing lines, nylon, guitar strings, telephone cord or piano wire.Whittaker, Wayne, ''Tough Guys'', Popular Mechanics, February 1943, Vol. 79 No. 2, pp. 44Steele, David E., ''Silent Sentry Removal'', Black Belt Magazine, August 1986, Vol. 24 No. 8, pp. 48–49 A stick may be used to tighten the garrote; ...

Carotid Sinus Reflex
In human anatomy, the carotid sinus is a dilated area at the base of the internal carotid artery just superior to the bifurcation of the internal carotid and external carotid at the level of the superior border of thyroid cartilage. The carotid sinus extends from the bifurcation to the "true" internal carotid artery. The carotid sinuses are sensitive to pressure changes in the arterial blood at this level. They are two out of the four baroreception sites in humans and most mammals. Structure The carotid sinus is the reflex area of the carotid artery, consisting of baroreceptors which monitor blood pressure. Function The carotid sinus contains numerous baroreceptors which function as a "sampling area" for many homeostatic mechanisms for maintaining blood pressure. The carotid sinus baroreceptors are innervated by the carotid sinus nerve, which is a branch of the glossopharyngeal nerve (CN IX). The neurons which innervate the carotid sinus centrally project to the solita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asphyxia
Asphyxia or asphyxiation is a condition of deficient supply of oxygen to the body which arises from abnormal breathing. Asphyxia causes generalized hypoxia, which affects all the tissues and organs, some more rapidly than others. There are many circumstances that can induce asphyxia, all of which are characterized by the inability of a person to acquire sufficient oxygen through breathing for an extended period of time. Asphyxia can cause coma or death. In 2015, about 9.8 million cases of unintentional suffocation occurred which resulted in 35,600 deaths. The word asphyxia is from Ancient Greek "without" and , "squeeze" (throb of heart). Causes Situations that can cause asphyxia include but are not limited to: airway obstruction (such as from asthma, laryngospasm, or simple blockage from the presence of foreign materials); from being in environments where oxygen is not readily accessible: such as underwater, in a low oxygen atmosphere, or in a vacuum; environments where s ...

Hyoid
The hyoid-bone (lingual-bone or tongue-bone) () is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid-cartilage. At rest, it lies between the base of the mandible and the third cervical vertebra. Unlike other bones, the hyoid is only distantly articulated to other bones by muscles or ligaments. It is the only bone in the human body that is not connected to any other bones. The hyoid is anchored by muscles from the anterior, posterior and inferior directions, and aids in tongue movement and swallowing. The hyoid bone provides attachment to the muscles of the floor of the mouth and the tongue above, the larynx below, and the epiglottis and pharynx behind. Its name is derived . Structure The hyoid bone is classed as an irregular bone and consists of a central part called the body, and two pairs of horns, the greater and lesser horns. Body The body of the hyoid bone is the central part of the hyoid bone. *At the front ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertebrate Trachea
The trachea (: tracheae or tracheas), also known as the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all animals' lungs. The trachea extends from the larynx and branches into the two primary bronchi. At the top of the trachea, the cricoid cartilage attaches it to the larynx. The trachea is formed by a number of horseshoe-shaped rings, joined together vertically by overlying ligaments, and by the trachealis muscle at their ends. The epiglottis closes the opening to the larynx during swallowing. The trachea begins to form in the second month of embryo development, becoming longer and more fixed in its position over time. Its epithelium is lined with column-shaped cells that have hair-like extensions called cilia, with scattered goblet cells that produce protective mucins. The trachea can be affected by inflammation or infection, usually as a result of a viral illness affectin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Club (weapon)
A club (also known as a cudgel, baton, bludgeon, truncheon, cosh, nightstick, or impact weapon) is a short staff or stick, usually made of wood, wielded as a weapon or tool since prehistory. There are several examples of blunt trauma, blunt-force trauma caused by clubs in the past, including at the site of Nataruk in Turkana County, Turkana, Kenya, described as the scene of a prehistoric conflict between bands of hunter-gatherers 10,000 years ago. Most clubs are small enough to be swung with one hand, although larger clubs may require the use of two to be effective. Various specialized clubs are used in martial arts and other fields, including the Baton (law enforcement), law-enforcement baton. The military Mace (bludgeon), mace is a more sophisticated descendant of the club, typically made of metal and featuring a spiked, knobbed, or flanged head attached to a shaft. Examples of cultural depictions of clubs may be found in mythology, where they are associated with strong figure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertebral Arteries
The vertebral arteries are major arteries of the neck. Typically, the vertebral arteries originate from the subclavian arteries. Each vessel courses superiorly along each side of the neck, merging within the skull to form the single, midline basilar artery. As the supplying component of the ''vertebrobasilar vascular system'', the vertebral arteries supply blood to the upper spinal cord, brainstem, cerebellum, and posterior part of brain. Structure The vertebral arteries usually arise from the posterosuperior aspect of the central subclavian arteries on each side of the body, then enter deep to the transverse process at the level of the 6th cervical vertebrae (C6), or occasionally (in 7.5% of cases) at the level of C7. They then proceed superiorly, in the transverse foramen of each cervical vertebra. Once they have passed through the transverse foramen of C1 (also known as the atlas), the vertebral arteries travel across the posterior arch of C1 and through the suboccipit ...
