Penile Cancer The corpus cavernosum and corpus spongiosum fill with blood during erection, the source of that blood are branches from the "dorsal artery of the penis" which arises from the "internal pudic" artery, which itself is a brach of the "anterior iliac" artery, which branches off of the large "desceding aorta". The spongy urethra within the penis proper is surrounded by a "loose connective tissue" called the "corpus spongiosum" (meaning "spongy body"). The corpus spongiosum is flexible and helps protect the delicate urethra. www.canceranswers.com /Penile.Cancer.html   (1725 words)

* Corpus spongiosum - (Sexuality): Definition The third component of the shaft is the corpus spongiosum, which runs along the length of the penis on the bottom, in the midline... The shaft or body of the penis consists of two parallel cylindrical bodies, the corpora cavernosa, and beneath them, surrounding the urethra, the corpus spongiosum. At the time of erection, blood flows into the cavernous and spongy bodies of the penis, or more precisely the corpora cavernosa and the corpus spongiosum. www.mimihu.com /sexuality/corpus_spongiosum.html   (263 words)

Male Genital Anatomy At the underside of the penis is the corpus spongiosum (S) that also can fill with blood to form an erection. Running down the center of the corpus spongiosum is the urethra. The corpus cavernosum makes up the bulk of the penis tissue. www.afraidtoask.com /members/mgenitalanatomy.html   (666 words)

The fore-end portion 13 of the artificial corpus cavernosum penis 11 may be formed to have a diameter larger than that of the rear portion 14, or the artificial corpus cavernosum penis 11 may have a generally uniform diameter in its entirety. The artificial corpus cavernosum device according to the present invention may be made of any material which are harmless to the human bodies and with which the functions of the device of the invention may be exerted to a desired extent. www.freepatentsonline.com /4235227.html   (2548 words)

PHIMOSIS - ABC Salutaris In the penis extremity, the corpus spongiosum dilates, forming the glans in which the final extremity of the urethra and the urethral meatus (urethral orifice) are found. The body of the penis contains the two chambers of the corpora cavernosa and the corpus spongiosum that surrounds the urethra. The body of the penis is the hanging part of the organ having in its extremity the glans. www.abcsalutaris.com /article.php?576   (512 words)

Erectile Tissue The corpus spongiosum, through which the urethra extends, is enlarged at the end to form a sensitive, cone-shaped "glans penis," which covers the ends of the corpora cavernosa and bears the urethral opening. Inside the glans penis, the corpus spongiosum is dilated and forms the "navicular fossa." The body, or shaft, of the penis is composed of three columns of erectile tissue. www.innerbody.com /text/repo21.html   (111 words)

Pelvis: External Genitalia As you move down the shaft, the corpus spongiosum becomes thicker until it called the bulb of the penis at the base. Conversely, the corpus cavernosa divert as you move down the shaft of the penis, toward the ischiopubic rami.

Basics of Reproductive Anatomy & Function The corpus spongiosum expands at the penis’s tip to underlie the glans penis, which is covered by the foreskin or prepuce at birth. The penis is filled with three columnar sections of erectile tissue, two corpora cavernosa under the dorsal surface and the corpus spongiosum under the ventral surface surrounding the urethra. The corpus luteum produces the hormone progesterone, which serves to maintain the uterine lining. www.users.csbsju.edu /~dgbrown/BIOL116/Notes/Animal_Reproduction.html   (1839 words)

The corpus spongiosum Viagra FAQ The penis is composed of three chambers, the paired corpra cavernosa and the corpus spongiosum.

Normal Sexual Function - Direct Source Pharmacy The corpus spongiosum and corpora cavernosa fill completely with blood, and, as this blood cannot escape, the penis extends further, and solidifies. Ejaculation can then occur, through contractions of the muscles surrounding the corpus spongiosum and corpora cavernosa, which propel the ejaculate from the urethra and out of the penis and the body. It is comprised of three cylindrical, spongy chambers, necessary for producing an erection; these chambers are called the corpus spongiosum and the corpora cavernosa. www.directsourcepharmacy.com /impotence/normal-sexual-function.html   (408 words)

Perineum & External Genitalia - Dissector Answers The corpus spongiosum is rooted as the bulb of the penis, which is attached to the perineal membrane, and receives the membranous urethra as it transverses the membrane. The three primary erectile bodies of the penis are the two corpora cavernosa and the corpus spongiosum. Instead of a corpus spongiosum, the female has two vestibular bulbs, which lie along the sides of the vestibule, and also expand as the glans clitoris to cap the distal ends of the corpora cavernosa. med.umich.edu /lrc/coursepages/M1/anatomy/html/pelvis/perineum_ans.html   (1484 words)

Perineum(PQ).doc The correct answer is: perineal membrane The bulbs of the vestibule/bulb of the corpus spongiosum are pieces of erectile tissue that attach to the perineal membrane. The corpus cavernosa are erectile bodies that lie beside the corpus spongiosum. Females have 2 corpus cavernosa plus 2 vestibular bulbs which are analogs to the corpus spongiosum. www-personal.umich.edu /~benwei/cgi-data/shared/linked/Perineum(PQ).doc   (2582 words)

CRI_2_4_1X_What_is_penile_cancer_35.asp The corpus spongiosum surrounds the urethra, a tube that carries urine from the bladder through the penis. When a man gets an erection, nerves signal to his body to store blood in the vessels inside the corpora cavernosa and corpus spongiosum. The third lies below them and is known as the corpus spongiosum. cancer.org /docroot/CRI/content/CRI_2_4_1X_What_is_penile_cancer_35.asp   (958 words)

The Complete Book of Men's Health - Part 1: Sexual Health At the base, behind the scrotum, the corpus spongiosum thickens again to form the root or bulb of the penis. The corpus spongiosum also contains erectile tissue that swells in a similar manner to the corpora cavernosa during erection. Several superficial veins are also visible, which drain the skin and glans of the penis, but not the deeper erectile tissues. www.tiscali.co.uk /lifestyle/healthfitness/menshealth/part1_1-1.html   (1323 words)

Endocrine Surgeon The penis is composed of three main compartments: the paired corpora cavernosa and the corpus spongiosum. The tunica albuginea and the corpus spongiosum albuginea form the walls of the three compartments. The corpora cavernosa make up the bulk of the penis and consists of bundles of smooth muscle fibres intertwined in extracellular matrix. www.endocrinesurgeon.co.uk /erectile/erectile2.html   (114 words)

Erection - Wikipedia, the free encyclopedia The corpus spongiosum is a single tubular structure located just above the corpora carvernonosa, and contains the male urethra, through which urine and semen pass during urination and ejaculation, respectively. The vessel system involved is known as the corpara cavernosa and the corpus spongiosum. Some prescription drugs are injected directly into the corpus cavernosum or used as urethral suppositories, directly causing erection even in the absence of sexual excitation, while others, such as Viagra, Cialis, or Levitra are taken orally and support erection that is due to sexual excitation. www.wikipedia.org /wiki/Erection   (718 words)

Corpus cavernosum - Wikipedia, the free encyclopedia A corpus cavernosum is one of a pair of a sponge-like regions of erectile tissue which contain most of the blood in the male penis during erection. The female anatomy has no corpus spongiosum, but instead two vestibular bulbs beneath the skin of the labia minora (at the entrance to the vagina), which expand at the same time as the glans clitoris to cap the ends of the corpora cavernosa. A little blood enters the corpus spongiosum; the remainder engorges the corpora cavernosa, which expand to hold 90% of the blood involved in an erection, increasing both in length and in diameter. www.wikipedia.org /wiki/Corpus_cavernosum   (422 words)

Male Genital Anatomy The corpus spongiosum with the urethra is related to the ventral aspect of the penile shaft and expands distally to from the glans penis. The corpus spongiosum becomes bulbous where it is covered by the bulbospongiosus to form the urethral bulb. Buck’s fascia is the deep layer of the penile fascia that covers both the corpora cavernosa and the corpus spongiosum in separate fascial compartments. www.bumc.bu.edu /Departments/PageMain.asp?Page=6939&DepartmentID=371   (2714 words)

Penis Anatomy Running through the center of the corpus spongiosum is the urethra, a common passage for semen and urine; the urethra ends in a slit-like opening at the tip of the glans penis. The corpus spongiosum is also considered erectile tissue. This area, however, does not become as enlarged as the other two during erection, for it contains more fibrous tissue and less space; unlike the corpora cavernosa, the corpus spongiosum has a constant blood flow during erection. www.go-penis-enlargement.com /penis_anatomy.html   (757 words)

Corpus spongiosum - Wikipedia, the free encyclopedia Corpus spongiosum (Plural: Corpora Spongiosa) is the mass of spongy tissue surrounding the male urethra within the penis. This page was last modified 08:11, 20 October 2005. en.wikipedia.org /wiki/Corpus_spongiosum   (44 words)

Penis - free-definition The glans of the penis is homologous to the clitoral glans, the corpora cavernosa are homologous to the body of the clitoris, the corpus spongiosum is homologous to the vestibular bulbs beneath the labia minora, and the scrotum is homologous to the labia minora, labia majora and clitoral hood. The urethra, which is the last part of the urinary tract, traverses the corpus spongiosum and its opening, known as the meatus, lies on the tip of the glans penis. The corpus spongiosum lies on the underside (known also as the ventral side) of the penis; the two corpora cavernosa lie next to each other on the upper side (dorsal side). www.netlexikon.akademie.de /Penis.html   (2246 words)

NDI Terminology - penis The third, the corpus spongiosum, lies centrally beneath them, expanding at its end to form the tip of the penis, the glans. Through the center of the corpus spongiosum runs the urethra, a narrow tube that carries urine and semen out of the body through an opening at the tip of the glans. Two of these bodies, the corpora cavernosa, lie side by side in the upper part of the penis. www.ndif.org /Terms/penis.html   (140 words)

Massive Member Natural Penis Enlargement There are 2 large chambers on the top of the penis (the Corpus Cavernosum) and 1 smaller chamber on the bottom of the penis (the Corpus Spongiosum). The remainder of the blood enters the Corpus Cavernosum, which is a sponge-like tissue that acts as the main blood-holding chamber of the penis. A small amount of blood enters the Corpus Spongiosum, which is the chamber used primarily for urination and ejaculation. www.newremedies.com /ssi/gifs/mmember.html   (469 words)

El_Sakka The hemodynamics of the corpus spongiosum and glans penis are somewhat different from those of the corpora cavernosa. During erection, the arterial flow increases in a similar manner; however, the pressure in the corpus spongiosum and glans is only one-third to one-half that in the corpora cavernosa because the tunical covering (thin over the corpus spongiosum and virtually absent over the glans) ensures minimal venous occlusion. From the neurons in the spinal cord and peripheral ganglia, the sympathetic and parasympathetic nerves merge to form the cavernous nerves, which enter the corpora cavernosa and corpus spongiosum to effect the neurovascular events during erection and detumescence. www.duj.com /Article/El_Sakka/El_Sakka.html   (3105 words)
