Interval 5 Flashcards
(58 cards)
trigone of the bladder
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.
rectum
the final straight portion of the large intestine in some mammals. the rectum is followed by the anal canal
ilium, ischium, and pubis
greater sciatic notch
acetabulum
a concave surface of the pelvis. The head of the femur meets with the pelvis at the acetabulum, forming the hip joint.[1][2]
ductus deferens
AKA vas deferens, the tube that transports sperm from the testes to the urethra
sacrospinous ligament
connects sacrum and ischial spine
sarcotuberous ligament
connects the sacrum and the ischial tuberosity
rectovesical pouch
the peritoneal cavity betwen the rectum and the bladder in males
tendinous arch of levator ani
where the levator ani meets the obturator internus muscle
obturator internus m.
pelvic diaphragm/levator ani
It is attached to the inner surface of the side of the lesser pelvis, and unites with its fellow of the opposite side to form the greater part of the floor of the pelvic cavity.
bulb of the penis
the bottom, medial portion of the penis.
bulbospongiosus m.
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.
crura of penis
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.
ischiocavernosus m.
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.
corpora cavernosa
one of a pair of sponge-like regions of erectile tissue which contain most of the blood in the penis during penile erection.
corpus spongiosum
the mass of spongy tissue surrounding the male urethra within the penis.
round ligament of uterus (ligamentum teres uteri)
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.
suspensory ligament of ovary
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.
proper ovarian ligament
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.
broad ligament
the wide fold of peritoneum that connects the sides of the uterus to the walls and floor of the pelvis.
mesometrium, mesosalpinx, and mesovarium
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.
cardinal ligament
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.
