Urinate
Urination is the release of urine from the bladder through the urethra in placental mammals, or through the cloaca in other vertebrates. It is the urinary system's form of excretion. It is also known medically as micturition, voiding, uresis, or, rarely, emiction, and known colloquially by various names including peeing, weeing, pissing, and euphemistically number one. The process of urination is under voluntary control in healthy humans and other animals, but may occur as a reflex in infants, some elderly individuals, and those with neurological injury. It is normal for adult humans to urinate up to seven times during the day. In some animals, in addition to expelling waste material, urination can mark territory or express submissiveness. Physiologically, urination involves coordination between the central, autonomic, and somatic nervous systems. Brain centres that regulate urination include the pontine micturition center, periaqueductal gray, and the cerebral cort ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urine
Urine is a liquid by-product of metabolism in humans and many other animals. In placental mammals, urine flows from the Kidney (vertebrates), kidneys through the ureters to the urinary bladder and exits the urethra through the penile meatus (males) or urethral meatus of the vulva (females) during urination. In other vertebrates, urine is excreted through the cloaca. Urine contains water-soluble by-products of Cell (biology), cellular metabolism that are rich in nitrogen and must be clearance (medicine), cleared from the Circulatory system, bloodstream, such as urea, uric acid and creatinine. A urinalysis can detect nitrogenous wastes of the mammalian body. Urine plays an important role in the earth's nitrogen cycle. In balanced ecosystems, urine fertilizes the soil and thus helps plants to grow. Therefore, Reuse of excreta, urine can be used as a fertilizer. Some animals use it to territory (animal)#Scent marking, mark their territories. Historically, aged or fermented urine (kn ...

Manneken Pis
(; ) is a landmark bronze fountain sculpture in central Brussels, Belgium, depicting a puer mingens; a Nudity, naked little boy urinating into the fountain's basin. Though its existence is attested as early as the mid-15th century, ''Manneken Pis'' was redesigned by the Duchy of Brabant, Brabantine sculptor :fr:Jérôme Duquesnoy l'Ancien, Jérôme Duquesnoy the Elder and put in place in 1619. Its Petit Granit, blue stone niche in rocaille style dates from 1770. The statue has been repeatedly stolen or damaged throughout its history. Since 1965, a replica has been displayed on site, with the original stored in the Brussels City Museum. ''Manneken Pis'' is one of the best-known symbols of Brussels and Belgium, inspiring several legends, as well as numerous imitations and similar statues, both nationally and abroad. The figure is regularly dressed up and its wardrobe consists of around one thousand different costumes. Since 2017, they have been exhibited in a dedicated museum ...

Squatting Position
Squatting is a versatile List of human positions, posture where the weight of the body is on the feet but the knees and hips are bent. In contrast, sitting involves supporting the weight of the body on the ischial tuberosities of the pelvis, with the lower buttocks in contact with the ground or a horizontal object. The angle between the legs when squatting can vary from zero to widely splayed out, flexibility permitting. Another variable may be the degree of forward tilt of the upper body from the hips. Squatting may be either full or partial. Crouching is usually considered to be synonymous with squatting. It is common to squat with one leg and kneel with the other leg. One or both heels may be up when squatting. Young children often instinctively squat. Among Chinese, Southeast Asian and Eastern European adults, squatting often takes the place of sitting or standing. Etymology Squatting comes from the Old French ''esquatir/escatir'', meaning to "compress/press down".Harper, D. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bladder
The bladder () is a hollow organ in humans and other vertebrates that stores urine from the kidneys. In placental mammals, urine enters the bladder via the ureters and exits via the urethra during urination. In humans, the bladder is a distensible organ that sits on the pelvic floor. The typical adult human bladder will hold between 300 and (10 and ) before the urge to empty occurs, but can hold considerably more. The Latin phrase for "urinary bladder" is ''vesica urinaria'', and the term ''vesical'' or prefix ''vesico-'' appear in connection with associated structures such as vesical veins. The modern Latin word for "bladder" – ''cystis'' – appears in associated terms such as cystitis (inflammation of the bladder). Structure In humans, the bladder is a hollow muscular organ situated at the base of the pelvis. In gross anatomy, the bladder can be divided into a broad (base), a body, an apex, and a neck. The apex (also called the vertex) is directed forward toward th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Detrusor
The detrusor muscle, also detrusor urinae muscle, muscularis propria of the urinary bladder and (less precise) muscularis propria, is smooth muscle found in the wall of the urinary bladder, bladder. The detrusor muscle remains relaxed to allow the bladder to store urine, and contracts during urination to release urine. Related are the urethral sphincter muscles which envelop the urethra to control the flow of urine when they contract. Structure The fibers of the detrusor muscle arise from the Posterior (anatomy), posterior surface of the body of pubic bone, body of the pubis in both sexes (musculi pubovesicales), and in the male from the adjacent part of the prostate. These fibers pass, in a more or less wiktionary:longitudinal, longitudinal manner, up the Anatomical terms of location#Superior and inferior, inferior surface of the urinary bladder, bladder, over its Apex of urinary bladder, apex, and then descend along its fundus of the urinary bladder#Fundus, fundus to become atta ...

Puer Mingens
A puer mingēns (; : puerī mingentēs ) is a figure in a work of art depicted as a prepubescent boy in the act of urinating, either actual or simulated. The puer mingens could represent anything from whimsy and boyish innocence to erotic symbols of virility and masculine bravado. Etymology and word play The term ''puer mingens'' comes from the Latin ''puer'', meaning "boy", and from the Latin ''mingens''; "urinating", the present participle of the verb ''mingere'' which means "to urinate". In Latin, verbs for urinating like ''mingere'' were frequently employed in the sense of "to ejaculate".Adams, J. N. ''The Latin Sexual Vocabulary''. Baltimore: Johns Hopkins University Press, 1982. This connotation was preserved in various descendants of Latin, including Italian with such words as ''pisciare''. On account of this, the urine emitted from the penis of the ''puer mingens'' can be interpreted symbolically as semen; and ''pueri mingentes'' are frequently found in works auguring fer ...

Urethra
The urethra (: urethras or urethrae) is the tube that connects the urinary bladder to the urinary meatus, through which Placentalia, placental mammals Urination, urinate and Ejaculation, ejaculate. The external urethral sphincter is a striated muscle that allows voluntary control over urination. The Internal urethral sphincter, internal sphincter, formed by the involuntary smooth muscles lining the bladder neck and urethra, receives its nerve supply by the Sympathetic nervous system, sympathetic division of the autonomic nervous system. The internal sphincter is present both in males and females. Structure The urethra is a fibrous and muscular tube which connects the urinary bladder to the external urethral meatus. Its length differs between the sexes, because it passes through the penis in males. Male In the human male, the urethra is on average long and opens at the end of the external urethral meatus. The urethra is divided into four parts in men, named after the lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pontine Micturition Center
In neuroanatomy, the pontine micturition center (PMC, also known as Barrington's nucleus) is a collection of neuronal cell bodies located in the rostral pons in the brainstem involved in the supraspinal regulation of micturition (urination). When activated, the PMC relaxes the urethral sphincter, allowing for micturition to occur. The PMC coordinates with other brain centers, including the medial frontal cortex, insular cortex, hypothalamus and periaqueductal gray (PAG). The PAG acts as a relay station for ascending bladder information from the spinal cord and incoming signals from higher brain areas. Regulation In humans and other mammals, neurons in the PMC send descending excitatory projections to spinally located parasympathetic neurons controlling the detrusor muscle of the bladder and inhibitory interneurons regulating Onuf's nucleus. Additionally, the PMC receives ascending input from the level of the lumbosacral spinal cord. During bladder filling, neurons within the PMC ...

External Urethral Orifice (male)
The urinary meatus (, ; : meati or meatuses), also known as the external urethral orifice, is the opening of the penis or vulva where urine exits the urethra during urination. It is also where semen exits during male ejaculation, and other fluids during female ejaculation. The meatus has varying degrees of sensitivity to touch. In human males The male external urethral orifice is the external opening of the urethra, normally located at the tip of the glans penis, at its junction with the frenular delta. It presents as a vertical slit, and continues longitudinally along the front aspect of the glans, which facilitates micturition. In some cases, the opening may be more rounded. This can occur naturally or may also occur as a side effect of excessive skin removal during circumcision. The meatus is a sensitive part of the male reproductive system. In human females The female external urethral orifice is where urine exits the urethra during urination. It is located about behin ...

Anatomical Plane
An anatomical plane is a hypothetical plane used to transect the body, in order to describe the location of structures or the direction of movements. In human anatomy and non-human anatomy, four principal planes are used: the median plane, sagittal plane, coronal plane, and transverse plane. * The median plane or midsagittal plane passes through the middle of the body, dividing it into left and right halves. * A para sagittal plane is any plane that runs parallel to the median plane, also dividing the body into left and right sections. * The dorsal plane divides the body into dorsal (towards the backbone) and ventral (towards the belly) parts. In human anatomy coronal plane is preferred, or sometimes the frontal plane, and the description may reference splitting the body into front and back parts, but this phrasing is not as clear for animals with a horizontal spine like quadrupeds or fish. * The transverse plane, also called the axial plane or horizontal plane, is perpendi ...

Lumbar
In tetrapod anatomy, lumbar is an adjective that means of or pertaining to the abdominal segment of the torso, between the diaphragm (anatomy), diaphragm and the sacrum. Naming and location The lumbar region is sometimes referred to as the lower vertebral column, spine, or as an area of the back in its proximity. In human anatomy the five lumbar vertebrae (vertebrae in the lumbar region of the back) are the largest and strongest in the movable part of the spinal column, and can be distinguished by the absence of a foramen transversarium, foramen in the transverse process, and by the absence of facets on the sides of the body. In most mammals, the lumbar region of the spine curves outward. Description The actual spinal cord terminates between vertebrae one and two of this series, called L1 and L2. The central nervous system, nervous tissue that extends below this point are individual strands that collectively form the cauda equina. In between each lumbar vertebra a nerve root exi ...
