Interval 5 Flashcards

1
Q

trigone of the bladder

A

a smooth triangular region of the internal urinary bladder formed by the two ureteral orifices and the internal urethral orifice. The area is very sensitive to expansion and once stretched to a certain degree, the urinary bladder signals the brain of its need to empty.

Q

bulbospongiosus m.

A

One of the superficial muscles of the perineum. It has a slightly different origin, insertion and function in males and females. In males, it covers the bulb of the penis. In females, it covers the vestibular bulb. In both sexes, it is innervated by the deep/muscular branch of the perineal nerve, which is a branch of the pudendal nerve.

Q

crura of penis

A

These bodies, part of the the posterior portion of the corpus cavernosum, are attached on their lateral aspect to the medial surface of the ischio-pubic ramus, and lies between Colles’ fascia and the urogenital diaphragm.

Q

ischiocavernosus m.

A

A muscle just below the surface of the perineum, present in both men and women, it helps flex the anus, and (in males) stabilize the erect penis or (in females) tense the vagina during orgasm. Kegel exercises (also known as pelvic floor exercises) can help tone the ischiocavernosus muscle.

It compresses the crus penis, and retards the return of the blood through the veins, and thus serves to maintain the organ erect.

Q

round ligament of uterus (ligamentum teres uteri)

A

It originates at the uterine horns in the parametrium and maintaines the uterus’s anteversion orientation (where the fundus of the uterus leans ventrally). It traverses the entire inguinal canal.

Q

suspensory ligament of ovary

A

a fold of peritoneum[1] that extends out from the ovary to the wall of the pelvis.
Some sources consider it a part of the broad ligament of uterus[2] while other sources just consider it a “termination” of the ligament.[3] It is not considered a true ligament in that it does not physically support any anatomical structures; however it is an important landmark and it houses the ovarian vessels.
It is directed upward over the iliac vessels.

Q

proper ovarian ligament

A

a fibrous ligament that connects the ovary to the lateral surface of the uterus.
This ligament should not be confused with the suspensory ligament of the ovary, which extends from the ovary in the other direction.

The broad ligament may be divided into three subcomponents:[1]
the mesentery of the uterus; the largest portion of the broad ligament
the mesentery of the Fallopian tube
he mesentery of the ovaries.

Q

cardinal ligament

A

a major ligament of the uterus. It is located at the base of the broad ligament of the uterus. Importantly, it contains the uterine artery and uterine vein.

25
Q

rectouterine pouch/excavation

A

the extension of the peritoneal cavity between the rectum and the posterior wall of the uterus in the female human body.

26
Q

vesicouterine puch

A

a shallow pouch formed from the peritoneum over the uterus and bladder, continued over the intestinal surface and fundus of the uterus onto its vesical surface, which it covers as far as the junction of the body and cervix uteri, and then to the bladder.

27
Q

crura of the clitoris

A

two erectile tissue structures, which together form a V-shape that converges on the clitoral body

28
Q

bulbs of the vestibule

A

aggregations of erectile tissue that are an internal part of the clitoris. They can also be found throughout the vestibule—next to the clitoral body, clitoral crura, urethra, urethral sponge, and vagina.
They are to the left and right of the urethra, urethral sponge, and vagina.

As the clitoral bulbs fill with blood, they tightly cuff the vaginal opening, causing the vulva to expand outward.
