Bridge Piercing
A bridge piercing is a facial piercing through the skin on the bridge of the nose, usually directly between the eyes of the wearer. A variation on this piercing, the vertical bridge piercing is a surface piercing, with all of the risks or potential complications related to surface piercings. History The bridge piercing is a relatively modern body modification practice. Unlike septum or nostril piercings, which have roots in ancient cultures, the bridge piercing has no known historical or indigenous origins. It is believed to have emerged in the late 20th century with the rise of the contemporary body modification movement. Body piercer Erik Dakota is often credited with popularizing the bridge piercing, reportedly coining the term "Erl" piercing in the 1980s after a client named Erl Van Aken, who was one of the first individuals to wear it regularly*. The piercing gained traction in alternative and punk subcultures throughout the 1990s, becoming more widely recognized due to i ...

Nasal Bridge
The nasal bridge is the upper part of the nose, where the nasal bones and surrounding soft tissues provide structural support. While commonly discussed in human anatomy, nasal bridges exist in various forms across many vertebrates, particularly mammals. The shape, size, and function of the nasal bridge are influenced by evolutionary adaptations, playing a key role in Respiration (physiology), respiration, sense of smell, and thermoregulation. Anatomy Humans In humans, the nasal bridge is the elevated region of the human nose, nose between the eyes. It is primarily formed by the two small, oblong nasal bones, which meet at the midline to form the internasal suture. The nasal bridge extends from the nasal root, where the nose meets the forehead, to the lower edge of the nasal bones. Laterally, it reaches the inner canthi, the medial corners of the eyes, creating a saddle-shaped contour across the upper nose. The height and shape of the nasal bridge vary among individuals and ...

Barbell (piercing)
Barbell style piercing jewelry is composed of a straight bar with a bead on each end, one or both beads unscrewable for removal and/or changing of the beads. Often one of the beads is fixed, either via epoxy or welding, so that only one bead is used to install or remove the jewelry. Barbell screw thread, threads are usually right-handed. They are named because they resemble the barbells that are used in Powerlifting, weightlifting. Types of barbells Internally threaded barbells Named because the bar has smooth ends with receiving threads tapped into the end of the bar. In internally threaded jewelry, the bead has a receiving tube machined into it (this is referred to as "countersunk"), with a threaded post extending from the center, which mates with the threaded receiving tube on the bar. Being much less likely to cause damage and irritation, especially at the time of piercing, internally threaded jewelry is considered superior to externally threaded jewelry. It is u ...

Captive Bead Ring
A captive bead ring (CBR), ball closure ring (BCR), captive hoop, or captive ball ring is a common example of body piercing jewelry. The captive bead or ball fits into a small opening in the circle of the ring. The bead is slightly larger than this opening and has small indentations or depressions that correspond to the ring's end-points so that it may fit snugly against them, thus completing the circuit of the ring. Often, a hole is drilled through the bead to allow easier fitting. It uses the natural tension (mechanics), tensile or compression (physical), compressive strength of the metal the ring is made of, usually surgical stainless steel, niobium, or titanium, to hold the bead tightly in place. The bead or ball itself may additionally be made from coloured glass, acrylic glass, acrylic or ceramic, or a gemstone. This is a popular piece of body jewelry because it conveniently allows the wearer to remove the ring by simply removing the captive bead; the bead is held firmly in ...

Human Nose
The human nose is the first organ of the respiratory system. It is also the principal organ in the olfactory system. The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two. The nose has an important function in breathing. The nasal mucosa lining the nasal cavity and the paranasal sinuses carries out the necessary conditioning of inhaled air by warming and moistening it. Nasal conchae, shell-like bones in the walls of the cavities, play a major part in this process. Filtering of the air by nasal hair in the nostrils prevents large particles from entering the lungs. Sneezing is a reflex to expel unwanted particles from the nose that irritate the mucosal lining. Sneezing can Transmission (medicine), transmit infections, because aerosols are created in which the Respiratory droplets, droplets can harbour pathogens. Another major function of the nose is olfactio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface Piercing
Surface piercings are Body piercing, piercings that are found on flat parts of the body, giving a double-pierced look that sits flat against the skin. A surface bar follows the plane of skin, while a standard piercing is pierced through the plane. Standard piercings have an entrance hole with an exit hole that is usually directly behind the entrance hole, whereas with a surface piercing the entrance and exit holes are next to each other on the skin surface. Types Some examples of surface piercings: *Corset piercing: a series of bilaterally symmetrical piercings, normally done on the back, intended to be laced like a corset. *Christina piercing: located at the mons pubis. *Madison piercing: a horizontal piercing located just above the collarbone, at the base of the neck. *Nape piercing: located on the back of the neck. *Neck piercing: located on the side of the neck. It is also called "Vampire Bites". *Hip piercing: located on or beside the hips (on the pelvis near the hips bones). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transplant Rejection
Transplant rejection occurs when transplanted tissue is rejected by the recipient's immune system, which destroys the transplanted tissue. Transplant rejection can be lessened by determining the molecular similitude between donor and recipient and by use of immunosuppressant drugs after transplant. Types Transplant rejection can be classified into three types: hyperacute, acute, and chronic. These types are differentiated by how quickly the recipient's immune system is activated and the specific aspect or aspects of immunity involved. Hyperacute rejection Hyperacute rejection is a form of rejection that manifests itself in the minutes to hours following transplantation. It is caused by the presence of pre-existing antibodies in the recipient that recognize antigens in the donor organ. These antigens are located on the endothelial lining of blood vessels within the transplanted organ and, once antibodies bind, will lead to the rapid activation of the complement system. ...

Piercing Migration
Piercing migration is a body piercing's movement from its initial location. Migration may be unnoticed, or painful with progression. It may be slight and brief, or continue until exiting the skin. Potential causes and effects of migration Migration varies widely. The most common case is heavy, small gauge earrings moving down until exiting the earlobe after most of a lifetime. It is dubbed the "cheese-cutter effect", because of its similarity to cutting cheese using a fine wire. Contemporary body and ear piercing jewelry mitigates the effect by increasing the weight to gauge ratio. However, migration remains possible, especially with heavy jewelry, even of large gauge. Another migration cause, though rare, is play or movement affecting the pierced or implanted area, either by causing a wound, or merely stretching the fistula in one direction, thus allowing tissue growth in the void behind. The latter can affect tongue piercings, for example, but neither normally induces exit fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brain
The brain is an organ (biology), organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It consists of nervous tissue and is typically located in the head (cephalization), usually near organs for special senses such as visual perception, vision, hearing, and olfaction. Being the most specialized organ, it is responsible for receiving information from the sensory nervous system, processing that information (thought, cognition, and intelligence) and the coordination of motor control (muscle activity and endocrine system). While invertebrate brains arise from paired segmental ganglia (each of which is only responsible for the respective segmentation (biology), body segment) of the ventral nerve cord, vertebrate brains develop axially from the midline dorsal nerve cord as a brain vesicle, vesicular enlargement at the rostral (anatomical term), rostral end of the neural tube, with centralized control over all body segments.
