Dorsal Veins Of The Penis
In human male anatomy, the dorsal veins of the penis are blood vessels that drain the shaft ( corpora cavernosa, corpus spongiosum), the skin and the glans of the human penis. They are typically located in the midline on the dorsal aspect of the penis and they comprise the superficial dorsal vein of the penis, that lies in the subcutaneous tissue of the shaft, and the deep dorsal vein of the penis, that lies beneath the deep fascia. Superficial dorsal vein The ''superficial dorsal vein of the penis'' belongs to the superficial drainage system. It is located within the superficial dartos fascia, a continuation of the Colles' fascia, on the dorsal surface of the penis and, in contrast to the deep dorsal vein, it lies outside the deeper Buck's fascia. It is formed by smaller superficial veins that merge on the dorsolateral aspect of the penis. It drains the prepuce and the skin of the shaft, and, running backward in the subcutaneous tissue, inclines to the right or left, and op ...

Penis
A penis (; : penises or penes) is a sex organ through which male and hermaphrodite animals expel semen during copulation (zoology), copulation, and through which male placental mammals and marsupials also Urination, urinate. The term ''penis'' applies to many intromittent organs of vertebrates and invertebrates, but not to all. As an example, the intromittent organ of most Cephalopoda is the hectocotylus, a specialized arm, and male spiders use their pedipalps. Even within the Vertebrata, there are morphological variants with specific terminology, such as Hemipenis, hemipenes. Etymology The word "penis" is taken from the Latin word for "Latin profanity#Synonyms and metaphors, tail". Some derive that from Proto-Indo-European language, Indo-European ''*pesnis'', and the Greek word πέος = "penis" from Indo-European ''*pesos''. Prior to the adoption of the Latin word in English, the penis was referred to as a "yard". The Oxford English Dictionary cites an example of the w ...

Intravenous Therapy
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein. The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water per os, by mouth. It may also be used to administer pharmaceutical drug, medications or other medical therapy such as blood transfusion, blood products or electrolytes to correct electrolyte imbalances. Attempts at providing intravenous therapy have been recorded as early as the 1400s, but the practice did not become widespread until the 1900s after the development of techniques for safe, effective use. The intravenous route is the fastest way to deliver medications and fluid replacement throughout the body as they are introduced directly into the circulatory system and thus quickly distributed. For this reason, the intravenous route ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penile Fracture
Penile fracture is rupture of one or both of the '' tunica albuginea'', the fibrous coverings that envelop the penis's '' corpora cavernosa''. It is caused by rapid blunt force to an erect penis, usually during vaginal intercourse, or aggressive masturbation. It sometimes also involves partial or complete rupture of the urethra or injury to the dorsal nerves, veins and arteries. Signs and symptoms A popping or cracking sound, significant pain, swelling, immediate loss of erection leading to flaccidity, and skin hematoma of various sizes are commonly associated with the sexual event. Causes Penile fracture is a relatively uncommon clinical condition. Vaginal intercourse and aggressive masturbation are the most common causes. A 2014 study of accident and emergency records at three hospitals in Campinas, Brazil, showed that woman on top positions caused the greatest risk with the missionary position being the safest. The research conjectured that when the receptive partner is o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internal Pudendal Vein
The internal pudendal veins (internal pudic veins) are a set of veins in the pelvis. They are the venae comitantes of the internal pudendal artery. Internal pudendal veins are enclosed by pudendal canal, with internal pudendal artery and pudendal nerve. They begin in the deep veins of the vulva and of the penis and scrotum, issuing from the bulb of the vestibule and the bulb of the penis, respectively. They accompany the internal pudendal artery, and unite to form a single vessel, which ends in the internal iliac vein. They receive the veins from the urethral bulb, the perineal and inferior hemorrhoidal veins. The deep dorsal vein of the penis Deep or The Deep may refer to: Places United States * Deep Creek (Appomattox River tributary), Virginia * Deep Creek (Great Salt Lake), Idaho and Utah * Deep Creek (Mahantango Creek tributary), Pennsylvania * Deep Creek (Mojave River tributary ... communicates with the internal pudendal veins, but ends mainly in the pudendal p ...

Pubic Symphysis
The pubic symphysis (: symphyses) is a secondary cartilaginous joint between the left and right superior rami of the pubis of the hip bones. It is in front of and below the urinary bladder. In males, the suspensory ligament of the penis attaches to the pubic symphysis. In females, the pubic symphysis is attached to the suspensory ligament of the clitoris. In most adults, it can be moved roughly 2 mm and with 1 degree rotation. This increases for women at the time of childbirth. The name comes from the Greek word ''symphysis'', meaning 'growing together'. Structure The pubic symphysis is a nonsynovial amphiarthrodial joint. The width of the pubic symphysis at the front is 3–5 mm greater than its width at the back. This joint is connected by fibrocartilage and may contain a fluid-filled cavity; the center is avascular, possibly due to the nature of the compressive forces passing through this joint, which may lead to harmful vascular disease. The ends of both pubi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circulatory System
In vertebrates, the circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the body. It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek meaning ''heart'', and Latin meaning ''vessels''). The circulatory system has two divisions, a systemic circulation or circuit, and a pulmonary circulation or circuit. Some sources use the terms ''cardiovascular system'' and ''vascular system'' interchangeably with ''circulatory system''. The network of blood vessels are the great vessels of the heart including large elastic arteries, and large veins; other arteries, smaller arterioles, capillaries that join with venules (small veins), and other veins. The circulatory system is closed in vertebrates, which means that the blood never leaves the network of blood vessels. Many invertebrates such as arthropods have an open circulatory system with a he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vesical Venous Plexus
The vesical venous plexus is a venous plexus situated at the fundus of the urinary bladder. It collects venous blood from the urinary bladder in both sexes, from the accessory sex glands in males, and from the corpora cavernosa of clitoris in females (via the v. dorsalis profunda clitoridis). It drains into the internal iliac veins via several vesical veins. Structure The vesical venous plexus envelops the inferior part of the bladder and the base of the prostate The prostate is an male accessory gland, accessory gland of the male reproductive system and a muscle-driven mechanical switch between urination and ejaculation. It is found in all male mammals. It differs between species anatomically, chemica .... Anastomoses It communicates with the pudendal and prostatic plexuses.

Arcuate Pubic Ligament
The pubic symphysis (: symphyses) is a secondary cartilaginous joint between the left and right superior rami of the pubis of the hip bones. It is in front of and below the urinary bladder. In males, the suspensory ligament of the penis attaches to the pubic symphysis. In females, the pubic symphysis is attached to the suspensory ligament of the clitoris.

Suspensory Ligament Of Penis
The suspensory ligament of the penis is a triangular midline structure anchoring the penis to the pubic symphysis, holding the penis close to the pubic bone and supporting it during erection. The ligament does not directly connect to the corpus cavernosum penis, but may still play a role in erectile dysfunction. The ligament can be surgically lengthened in a procedure known as ligamentolysis, which is a form of penis enlargement. Anatomy Structure The ligament is composed of a midline lamina, and two lateral laminae. Some of the fibres of the ligament come to constitute the fundiform ligament of the penis, extending into the scrotal septum. Attachments The ligament attaches by its apex onto the symphysis pubis and linea alba, and by its base onto the dorsal and lateral aspects of the corpora cavernosa penis. The midline lamina splits inferiorly/distally to attach onto each corpus cavernosus penis lateral to the groove of the deep dorsal vein of penis, whereas each la ...

Root Of Penis
In human male anatomy, the radix () or root of the penis is the internal and most proximal portion of the human penis that lies in the perineum. Unlike the pendulous body of the penis, which is suspended from the pubic symphysis, the root is attached to the pubic arch of the pelvis and is not visible externally. It is triradiate in form, consisting of three masses of erectile tissue; the two diverging crura, one on either side, and the median bulb of the penis or urethral bulb. Approximately one third to one half of the penis is embedded in the pelvis and can be felt through the scrotum and in the perineum. Structure The root of the penis begins directly below the bulbourethral glands, or ''Cowper glands'', and consists of three long masses of tissue; the bulb and the crura. The bulb of the penis is an enlarged mass of erectile tissue that is located in the midline of the root and is traversed by the male urethra. It continues as a long cylindrical body on the ventral ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
