Anatomy › Identifying Reproductive Organs
Which of the following choices is found in the spermatic cord?
Ductus deferens
Testes
Scrotum
Epididymis
Tunica vaginalis
The contents of the spermatic cord include the following: ductus deferens, blood vessels, lymphatics, and nerves. These features are bundled together to connect the testes to the abdominal cavity. The spermatic cord is sensitive to torsion, in which the testes rotate within its sac and block bloody supply. This can lead to testicular damage within a couple of hours.
What is located on the posterolateral aspect of the testes in the male scrotum?
Epididymis
Vas deferens
Bulbourethral gland (Cowper's gland)
Seminal vesicles
Gubernaculum
The epididymis, which is on the posterolateral aspect of the testes, gives rise to the vas deferens. The vas deferens travels superiorly in the spermatic cord, furthermore joining with the seminal vesicles (located posterior to the urinary bladder).
The bulbourethral gland is located inferior to the prostate and posteriolateral to the membranous urethra. The gubernaculum (scrotal ligament) is located inferior to each teste, attaching them to the scrotum.
The ovarian ligament connects __________.
the ovary to the uterus
the ovary to the kidneys
the ovary to the urinary bladder
the ovary to the pelvis
does not connect any of these
The ovarian ligament connects the uterus to the ovary. It is different from the suspensory ligament of the ovary, which binds the ovary to the pelvis. There is no ligament connecting the ovary to the urinary bladder or the kidneys. Adherences between the ovary and these organs would be pathological.
Which of these is not part of the male reproductive system?
Vestibule
Bulbourethral glands
Ductus deferens
Prostate
The prostate gland and bulbourethral glands are glands of the male reproductive system which contribute secretions to seminal fluid. The ductus, or vas, deferens is a duct of the male reproductive system which opens into the urethra. The vestibule, however, is a part of the female reproductive system. It is an entrance of the vagina between the labia minora and has the hymen at the vaginal orifice.
Which of the following make up the erectile bodies in the penis?
Corpus spongiosum and corpus cavernosum
Corpus spongiosum and tunica albuginea
Corpus spongiosum and prostate
Corpus cavernosum and tunica albuginea
Corpus cavernosum and prostate
The erectile bodies consist of the corpus spongiosum and two corpora cavernosa (plural form). The tunica albuginea encloses a corpus cavernosum, but it is not itself an erectile body. The prostate lies posterioinferior to the male bladder and superior to the penis; it is not part of the penis.
Which organ provides a normal site of fertilization?
Fallopian tube
Ovary
Vagina
Uterus
Normal fertilization occurs in the ampulla of the fallopian tube (the wider region). The ovaries produce oocytes (eggs), one of which is released per month to be fertilized. If the egg is fertilized, it then travels to and embeds in the uterus, where it develops as a fetus. The vagina receives the penis and semen during sexual intercourse and later provides a passage for delivery of an infant.
The uterus normally lies __________ to the bladder.
posterior
anterior
superior
lateral
inferior
The uterus is located in the pelvis and is positioned posterior (dorsal) to the bladder and anterior (rostral) to the rectum. The uterus can be divided into four segements: the fundus, corpus, cervix, and internal os. The human uterus is approximately 7.5 cm long and 4.5 cm in width. It is pear shaped.
Which statement is true regarding the vesicouterine pouch that is formed by the peritoneum?
The vesicouterine pouch is anterior to the rectouterine pouch in females
The vesicouterine pouch lies posterior to the rectouterine pouch in females
The vesicouterine pouch lies anterior to the rectouterine pouch in males
The vesicouterine pouch lies posterior to the rectouterine pouch in males
There is no vesicouterine pouch in females or males
The vesicouterine pouch is present only in female anatomy. It is located anterior to the rectouterine pouch and lies between the bladder and the uterus, whereas the rectouterine pouch is formed between the uterus and the rectum.
In males, the pouch formed is the rectovesical pouch, located between the bladder and the rectum.
Which of the following ligaments connects the ovary to the abdominal wall?
Suspensory ligament
Round ligament
Ovarian ligament
Broad ligament
Gubernaculum
The broad ligament connects the utuerus to the abdominal wall. It is comprised of several smaller structures as well, including the ovarian ligament, round ligament, and suspensory ligament. The ovarian ligament connects the ovary to uterus, the round ligament connects the uterus to the labia majora, and the suspensory ligament connects the ovary to the abdominal wall.
The gubernaculum connects the testes to scrotum (in males).
What would you find contained in the deep perineal pouch?
Deep transverse perineal muscle, dorsal artery and nerve, urethra, vagina
Deep transverse perineal muscle, dorsal artery and nerve, penile urethra
Cremaster muscle, dorsal artery and nerve, urethra, vagina
Cremaster muscle, dorsal artery and nerve, penile urethra
Internal urethral sphincter, deep transverse muscle, urethra, vagina
The deep transverse perineal muscle, dorsal artery and nerve, urethra, and vagina would all be contents of the deep perineal pouch, which would be exposed after removing the perineal membrane.
The penile urethra is distal to the perineal pouch. The cremaster muscle is located in the testes, distal to the perineal pouch. The internal urethral sphincter is internal in the bladder.
