Uvula Piercing
A uvula piercing is a body piercing through the uvula, the projection of the soft palate between the tonsils. This is a rare piercing. Captive bead rings or other small rings are the most commonly seen jewellery in uvula piercings. Health issues The piercing is rare due to the gag reflex The pharyngeal reflex or gag reflex is a reflex muscular contraction of the back of the throat, evoked by touching the roof of the mouth, the back of the tongue, the area around the tonsils, the uvula, and the back of the throat. It, along with othe ..., which makes it difficult to administer or receive it. Should jewelry pierced through the uvula come loose, it may be swallowed or even inhaled, which would require surgery to remove. As with tongue piercings, there is a risk of crush injury during the piercing, swelling, and infection. The jewelry will also pull the uvula down during sleep, reducing the diameter of the nasal airway and increasing the chance of sleep-related breathing disorders suc ...

Uvula
The palatine uvula, usually referred to as simply the uvula, is a conic projection from the back edge of the middle of the soft palate, composed of connective tissue containing a number of racemose glands, and some muscular fibers. It also contains many serous glands, which produce thin saliva. It is only found in human beings. Structure Muscle The muscular part of the uvula () shortens and broadens the uvula. This changes the contour of the posterior part of the soft palate. This change in contour allows the soft palate to adapt closely to the posterior pharyngeal wall to help close the nasopharynx during swallowing. Its muscles are controlled by the pharyngeal branch of the vagus nerve. Variation A bifid or bifurcated uvula is a split or cleft uvula. Newborns with cleft palate often also have a split uvula. The bifid uvula results from incomplete fusion of the palatine shelves but it is considered only a slight form of clefting. Bifid uvulas have less muscle in them th ...

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 tensile or 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 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 place so that it will not easily fall out.

Body Piercing
Body piercing, which is a form of body modification, is the practice of puncturing or cutting a part of the human body, creating an opening in which jewelry may be worn, or where an implant could be inserted. The word ''piercing'' can refer to the act or practice of body piercing, or to an opening in the body created by this act or practice. It can also, by metonymy, refer to the resulting decoration, or to the decorative jewelry used. Piercing implants alter body and/or skin profile and appearance (e.g. golden threads installed subdermal, platinum, titanium or medical grade steel subdermal implants). Although the history of body piercing is obscured by popular misinformation and by a lack of scholarly reference, ample evidence exists to document that it has been practiced in various forms by multiple sexes since ancient times throughout the world.Body piercing can be performed on people of all ages, although most minors are only permitted to have earlobe piercings.

Soft Palate
The soft palate (also known as the velum, palatal velum, or muscular palate) is, in mammals, the soft tissue constituting the back of the roof of the mouth. The soft palate is part of the palate of the mouth; the other part is the hard palate. The soft palate is distinguished from the hard palate at the front of the mouth in that it does not contain bone. Structure Muscles The five muscles of the soft palate play important roles in swallowing and breathing. The muscles are: # Tensor veli palatini, which is involved in swallowing # Palatoglossus, involved in swallowing # Palatopharyngeus, involved in breathing # Levator veli palatini, involved in swallowing # Musculus uvulae, which moves the uvula These muscles are innervated by the pharyngeal plexus via the vagus nerve, with the exception of the tensor veli palatini. The tensor veli palatini is innervated by the mandibular division of the trigeminal nerve (V3). Function The soft palate is moveable, consisting of muscle f ...

Gag Reflex
The pharyngeal reflex or gag reflex is a reflex muscular contraction of the back of the throat, evoked by touching the roof of the mouth, the back of the tongue, the area around the tonsils, the uvula, and the back of the throat. It, along with other aerodigestive reflexes such as reflexive pharyngeal swallowing, prevents objects in the oral cavity from entering the throat except as part of normal swallowing and helps prevent choking, and is a form of coughing. The pharyngeal reflex is different from the laryngeal spasm, which is a reflex muscular contraction of the vocal cords. Reflex arc In a reflex arc, a series of physiological steps occur very rapidly to produce a reflex. Generally a sensory receptor receives an environmental stimulus, in this case from objects reaching nerves in the back of the throat, and sends a message via an afferent nerve to the central nervous system (CNS). The CNS receives this message and sends an appropriate response via an efferent nerve (also known a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sleep And Breathing
When we sleep, our breathing changes due to normal biological processes that affect both our respiratory and muscular systems. Physiology Sleep Onset Breathing changes as we transition from wakefulness to sleep. These changes arise due to biological changes in the processes that regulate our breathing. When we fall asleep, minute ventilation (the amount of air that we breathe per minute) reduces due to decreased metabolism. Non-REM (NREM) Sleep During NREM sleep, we move through three sleep stages, with each progressively deeper than the last. As our sleep deepens, our minute ventilation continues to decrease, reducing by 13% in the second NREM stage and by 15% in the third. For example, a study of 19 healthy adults revealed that the minute ventilation in NREM sleep was 7.18 liters/minute compared to 7.66 liters/minute when awake. Ribcage & Abdominal Muscle Contributions Rib cage contribution to ventilation increases during NREM sleep, mostly by lateral movement, and is detected ...

Piercing Migration
Piercing migration is the process that occurs when a body piercing moves from its initial location. This process can be painful or go unnoticed, until it has progressed. Given enough time, a ring may migrate entirely outside of the skin, although it may only migrate a small amount and come to rest. Potential causes and effects of migration The effects of migration can vary widely. The most common form of migration is the way that heavy small gauge earrings will migrate downwards out of the earlobe, as is common in older women who have worn earrings most of their lives. This is known as the "cheesecutter effect", as its action is easily compared to the method of cutting cheese with a fine wire. Contemporary body and ear piercing jewelry is much more balanced in its weight to gauge ratio, although migration is still possible with heavy jewelry, even if it is of large gauge. Play or movement of the area pierced or implanted can also lead to migration, but it's not likely. Sometimes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
