Shechita
In Judaism, ''shechita'' (anglicized: ; he, ; ; also transliterated ''shehitah, shechitah, shehita'') is slaughtering of certain mammals and birds for food according to ''kashrut''. Sources states that sheep and cattle should be slaughtered "as I have instructed you", but nowhere in the Torah are any of the practices of ''shechita'' described. Instead, they have been handed down in Rabbinic Judaism's Oral Torah, and codified in ''halakha''. Species The animal must be of a permitted species. For mammals, this is restricted to ruminants which have split hooves. For birds, although biblically any species of bird not specifically excluded in would be permitted, doubts as to the identity and scope of the species on the biblical list led to rabbinical law permitting only birds with a tradition of being permissible. Fish do not require kosher slaughter to be considered kosher, but are subject to other laws found in which determine whether or not they are kosher (having both ...

Kashrut
(also or , ) is a set of dietary laws dealing with the foods that Jewish people are permitted to eat and how those foods must be prepared according to Jewish law. Food that may be consumed is deemed kosher ( in English, yi, כּשר), from the Ashkenazic pronunciation (KUHsher) of the Hebrew (), meaning "fit" (in this context: "fit for consumption"). Although the details of the laws of are numerous and complex, they rest on a few basic principles: * Only certain types of mammals, birds and fish meeting specific criteria are kosher; the consumption of the flesh of any animals that do not meet these criteria, such as pork, frogs, and shellfish, is forbidden. * Kosher mammals and birds must be slaughtered according to a process known as ; blood may never be consumed and must be removed from meat by a process of salting and soaking in water for the meat to be permissible for use. * Meat and meat derivatives may never be mixed with milk and milk derivatives: separate equipm ...

Hullin
Hullin or Chullin (lit. "Ordinary" or "Mundane") is the third tractate of the Mishnah in the Order of Kodashim and deals with the laws of ritual slaughter of animals and birds for meat in ordinary or non-consecrated use (as opposed to sacred use), and with the Jewish dietary laws in general, such as the laws governing the prohibition of mixing of meat (''fleishig'') and dairy (''milchig'') products. While it is included in the Seder Kodashim, it mainly discusses non-consecrated things and things used as the ordinary human food, particularly meats; it is therefore sometimes called "Shehitat Hullin" ("Slaughtering of Non-Consecrated Animals"). It comprises twelve chapters, dealing with the laws for the slaughtering of animals and birds for meat for ordinary as opposed to sacred use, with other rules relating to the eating of meat, and with the dietary laws in general. The rules prescribed for kosher slaughtering, known as Shechita, include five things which must be avoided: there ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terefah
Terefah ( he, טְרֵפָה, lit. "torn by a beast of prey"; plural ''treifot'') refers to either: * A member of a kosher species of mammal or bird, disqualified from being considered kosher, due to pre-existing mortal injuries or physical defects. * A specific list of mortal injuries or physical defects that disqualify a member of a kosher species of mammal or bird from being kosher. Biblical prohibition The biblical prohibition of eating ''terefah'' stems from the verse: According to the Talmud,Hullin 37a there were originally only eight types of terefah, however, the author(s) of the Mishnah added eighteen items to the list. Eventually, Maimonides added even more to finish the list of terefah conditions at 70. Rabbi Joseph Caro organized all of these symptoms in the Shulchan Aruch (Yoreh De'ah, 29-60) by categorizing them according to parts of the animal, their minute malady, and any disease, fracture, or abnormality they may possess.The Jewish Encyclopedia.

Oral Torah
According to Rabbinic Judaism, the Oral Torah or Oral Law ( he, , Tōrā šebbəʿal-pe}) are those purported laws, statutes, and legal interpretations that were not recorded in the Five Books of Moses, the Written Torah ( he, , Tōrā šebbīḵṯāv, "Written Law", label=none), but nonetheless are regarded by Orthodox Jews as prescriptive and given at the same time. This holistic Jewish code of conduct encompasses a wide swathe of rituals, worship practices, Godman and interpersonal relationships, from dietary laws to Sabbath and festival observance to marital relations, agricultural practices, and civil claims and damages. According to Rabbinic Jewish tradition, the Oral Torah was passed down orally in an unbroken chain from generation to generation until its contents were finally committed to writing following the destruction of the Second Temple in 70 CE, when Jewish civilization was faced with an existential threat, by virtue of the dispersion of the Jewish people.

Vagus Nerve
The vagus nerve, also known as the tenth cranial nerve, cranial nerve X, or simply CN X, is a cranial nerve that interfaces with the parasympathetic control of the heart, lungs, and digestive tract. It comprises two nerves—the left and right vagus nerves—but they are typically referred to collectively as a single subsystem. The vagus is the longest nerve of the autonomic nervous system in the human body and comprises both sensory and motor fibers. The sensory fibers originate from neurons of the nodose ganglion, whereas the motor fibers come from neurons of the dorsal motor nucleus of the vagus and the nucleus ambiguus. The vagus was also historically called the pneumogastric nerve. Structure Upon leaving the medulla oblongata between the olive and the inferior cerebellar peduncle, the vagus nerve extends through the jugular foramen, then passes into the carotid sheath between the internal carotid artery and the internal jugular vein down to the neck, chest, and abdom ...

Jugular Vein
The jugular veins are veins that take deoxygenated blood from the head back to the heart via the superior vena cava. The internal jugular vein descends next to the internal carotid artery and continues posteriorly to the sternocleidomastoid muscle. Structure and Function There are two sets of jugular veins: external and internal. The left and right external jugular veins drain into the subclavian veins. The internal jugular veins join with the subclavian veins more medially to form the brachiocephalic veins. Finally, the left and right brachiocephalic veins join to form the superior vena cava, which delivers deoxygenated blood to the right atrium of the heart. The Jugular veins help carry blood from the heart to and from the brain. An average human brain weighs about 3 pounds, and gets about 15%-20% of the blood that the heart pumps out. It is important for the brain to get enough blood for many reasons. The jugu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Babylonian Talmud
The Talmud (; he, , Talmūḏ) is the central text of Rabbinic Judaism and the primary source of Jewish religious law (''halakha'') and Jewish theology. Until the advent of modernity, in nearly all Jewish communities, the Talmud was the centerpiece of Jewish cultural life and was foundational to "all Jewish thought and aspirations", serving also as "the guide for the daily life" of Jews. The term ''Talmud'' normally refers to the collection of writings named specifically the Babylonian Talmud (), although there is also an earlier collection known as the Jerusalem Talmud (). It may also traditionally be called (), a Hebrew abbreviation of , or the "six orders" of the Mishnah. The Talmud has two components: the Mishnah (, 200 CE), a written compendium of the Oral Torah; and the Gemara (, 500 CE), an elucidation of the Mishnah and related Tannaitic writings that often ventures onto other subjects and expounds broadly on the Hebrew Bible. The term "Talmud" may refer to eith ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Esophagus
The esophagus (American English) or oesophagus (British English; both ), non-technically known also as the food pipe or gullet, is an organ in vertebrates through which food passes, aided by peristaltic contractions, from the pharynx to the stomach. The esophagus is a fibromuscular tube, about long in adults, that travels behind the trachea and heart, passes through the diaphragm, and empties into the uppermost region of the stomach. During swallowing, the epiglottis tilts backwards to prevent food from going down the larynx and lungs. The word ''oesophagus'' is from Ancient Greek οἰσοφάγος (oisophágos), from οἴσω (oísō), future form of φέρω (phérō, “I carry”) + ἔφαγον (éphagon, “I ate”). The wall of the esophagus from the lumen outwards consists of mucosa, submucosa (connective tissue), layers of muscle fibers between layers of fibrous tissue, and an outer layer of connective tissue. The mucosa is a stratified squamous epithel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trachea
The trachea, also known as the windpipe, is a Cartilage, cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with 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 annular ligaments of trachea, 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. It is epithelium lined with columnar epithelium, 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, us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
