After the bladder begins to enlarge, the adjacent portion of the urogenital sinus becomes slightly constricted. This marks the beginning of the urethra. In the female the constricted part represents practically the entire urethra. In the male it represents only the proximal end, the other portion developing in connection with the penis (p. ).

The penile urethra lies within the corpus spongiosum of the penis and transitions from a pseudostratified columnar at its beginning to a stratified squamous at the urethral orifice. V. Development of the gonads and extra-testicular ducts. As noted in the urinary system, the urinary and reproductive systems share a common developmental origin.
1) Identify on diagrams of the male reproductive system, the testes, scrotum, sperm ducts, prostate gland, urethra and penis, and state the functions of these parts. testes- Produces sperm and male sex hormone, testosterone scrotum- sack of skin which holds the testis sperm duct- carries sperm from testes to urethra prostate gland- produces alkaline fluid to add to sperm to. The prostate is a gland of the male reproductive adults, it is about the size of a walnut. The prostate is located in the pelvis. Within it sits the urethra coming from the bladder which is called the prostatic urethra and which merges with the two ejaculatory ducts.. The mean weight of the normal prostate in adult males is about 11 grams, usually ranging between 7 and 16 : Internal pudendal artery, inferior vesical artery, .

penile/spongy urethra extends the length of the penis and opens to the outside at the external urethral orifice. Ducts from the bulbourethral glands open into this. The male canine reproductive tract consists of the male genital organs including the scrotum, the two testes (normally located within the scrotum), the epididymides, the deferent ducts (tube that leads from the epididymis to the urethra), the spermatic cords, the prostate (an accessory gland), the penis and the urethra (the common passageway of.
The _____ of the penis fill(s) with blood during sexual arousal, causing an erection. a) corpus spongiosum b) corpora cavernosa c) urethra d) glans penis.
surrounds the urethra and extends all the way to the tip of the penis, where it forms the glans. Functions of penis contains the urethra, the terminal duct for both urinary and reproductive tracts; during sexual arousal, penis becomes erect, serving as a penetrating copulatory organ during sexual intercourse.
The genital tubercles of an eight week old embryo of either sex are identical. They both have a glans area, which will go on to form the glans clitoridis (females) or glans penis (males), a urogenital fold and groove, and an anal tubercle.
At around ten weeks, the external genitalia are still similar. The structures of the male reproductive system include the testes, the epididymides, the penis, and the ducts and glands that produce and carry semen.
Sperm exit the scrotum through the ductus deferens, which is bundled in the spermatic cord. The seminal vesicles and prostate gland add fluids to the sperm to create semen. Scrotum. Urethra: The urethra carries urine from the bladder, through the penis, and out of the body.
In men, the urethra also carries semen, which is ejaculated during orgasm. Seminal vesicles: Attached to the vas deferens near the base of the bladder, these sac-like pouches produce a fluid that is rich in sugar (fructose).
The sperm, then travel from the epididymis to the vas deference. They then arrive at the Ampulla, where they receive secretions from the Seminal vesicle. The sperm are then forced toward the urethra through the ejaculatory duct, but first passing the prostate gland, getting a milky fluid and becoming semen.
The external organs of the male are scrotum, testes, and penis. The internal organ is epididymis, ejaculatory ducts, vas deferens, prostate gland, seminal vesicle, and urethra. The sperm travels through internal organ and reaches to urethra by a sequence of the organ.
• Epididymis: It is a long coiled tube placed on the back of the testicles. Since urine and semen both pass through the urethra, A. there is often urine mixed with semen during an ejaculation.B.

Penis - The organ of copulation. The accessory sex glands. Two seminal vesicles - contribute fluid to semen. Two bulbo-urethral glands (Cowper's glands) - contribute fluid to. Knowledge of penile embryology and anatomy is essential to any pediatric urologist in order to fully understand and treat congenital anomalies.
Sex differentiation of the external genitalia occurs between the 7th and 17th weeks of gestation. The Y chromosome initiates male differentiation through the SRY gene, which triggers testicular by: A man's sexual anatomy is a straightforward affair.
The primary structure is the penis. This organ does triple duty serving a man's sexual, reproductive, and urinary functions. The penis includes these structures: Glans: The head of the penis. The urethral opening at the tip of the glans allows urine and semen to leave the penis.
Reproduction can be defined as the process by which an organism continues its species. In the human reproductive process, two kinds of sex cells (gametes), are involved: the male gamete (sperm), and the female gamete (egg or ovum).
These two gametes meet within the female's uterine tubes located one on each side of the upper pelvic cavity, and.
