Pelvis I and II Flashcards
What type of Joint is the Sacroiliac joint?
Synovial Joint
What Type of joint are the Lumbosacral and sacrococcygeal joints and the pubi symphisis joints?
These are all secondary cartilaginous joints
The sacrotuberous and sacrospinous ligaments are responsible for what?
These both prevent anteriorinferior displacement of the superior sacrum and convert the greater and lesser sciatic notches into sciatic foramina.
Where does the sacrospinous ligament run from?
The sacrospinous ligament runs from the sacrum to the ischium spine.
Where does the sacrotuberous ligament run from?
The Sacrum to the ischial tuberosity
What foramen in the pelvis does the piriformis pass through?
The piriformis passes through the greater sciatic foramen and attaches to the femurs greater trochanter.
This muscle serves as a bed for a nerve plexus. (Coccygeal plexus)
The pelvic diaphram is composed of what two muscles?
The levator ani and the coccygeus muscle.
The levator ani is a muscle body composed of three seperate parts. What are these parts listed medially to laterally?
Medially to laterally:
Puborectalis (Sometimes treated as part of the pubococcygeus)
Pubococcygeus
Iliococcygeus.
The ureters are considered embrologically….
Retroperitoneal muscular tubes
In females the ureter passes…. to the uterine arties
Passes Medial to the uterine arteries
In males the ductus deferens rests between….
In males the ductus deferens rests between the ureters and the peritoneum.
The trigone of the bladder is the…
The trigone is the triangle between the uteric and urethral openings.
In men the uvula is…
The uvula is a projection of the trigone that is visible in older men.
The wall of the bladder is primarily made up of this muscle….
Detrusor muscle.
In females the muscle of the bladders neck is continuous with what structure?
The muscles of the bladder become continuous with the urethra in females.
In males the muscle of the bladders neck is continuous with what structure
In males the muscle of the bladders neck is continuous with the prostates fibromuscular tissue. This prevents semen from entering the bladder.
The male penis has …. urethra curves when flaccid and …. urethral curves when erect.
The male penis has 2 urethra curves when flaccid and one when erect.
This structure in the prostate is a cul-de-sac remnant of the uterovaginal canal in the seminal colliculus
This structure is known as the prostatic utrical.
The opening of the ejaculatory ducts can be found within what structure?
The seminal colliculus
The openings of the prostatic ducts can be found within what structure?
Just lateral to the seminal colliculus
This funnel shaped structure containing fimbrae in the uterine tube is known as the
Infundibulum
This is the widest and longest portion of the uterine tube
This is known as the ampulla
This is the portion of the uterine tube that enters the uterine horns
This is known as the isthmus
This is the short segment of the uterine tube found within the uterine wall
This is known as the uterine part of the uterine tube.
The broad ligament is the mesentery of the uterus and has many subdivisions. What are the subdivisions.
The suspensory Ligament
The mesovarium
The Mesosalpinx
And the mesometrium
The suspensory ligament accomplishes what job?
Coneys ovarian vessels, lymphatics, and nerve.
The mesovarium accomplishes what job?
The mesovarium suspends the ovary.
The mesosalpinx accomplishes what job?
Suspends the uterine tube
The Mesometrium accomplishes what job?
The mesometrium suspends most of the uterus.
What is the typical position of the uterus?
Anteverted and anteflexed.
The vagina is located where in comparison to the urethra and bladder, as well as the rectum?
The vagina is located posterior to the urethra and bladder and anterior to the rectum.
What is the innervation of the vagina?
Th upper 3/4 is autonomically controlled where as the lower 1/4 is somatically controlled and innervated by the deep perineal branch of the pudendal.
When the ductus deferens joins the seminal vesicle what does it become?
The ejaculatory duct which converges upon the seminal colliculus of the prostatic urethra.
What components make up semen?
Semen is a mixture of secretions by the testes, seminal vesicles, prostate, and bulbourethral glands.
The ducts of the bulbourethral glands ope into what part of the penis?
These ducts open into the spongy urethra in the bulb of the penis.
The pelvic fascia is a continuation of what fascia source?
The endoabdominal fascia.
The extraperitoneal/subperitoneal reflections are considered?
These are considered outside or below the peritoneal cavity including most of the pelvic viscera.
The primarily retroperitoneal structures of the pelvis are what?
Kidneys, ureter, rectum, anal canal, and male prostate, seminal vesicles, and vas deferens.
The intraperitoneal structures of the pelvis include?
Uterus, ovaries, and uterine tubes.
The uterus is part of what peritoneal reflection?
This is a special case and is considered secondarily IP
Where is the rectovesicular pouch found?>
This space is found in males and lies between the bladder/prostate and the rectum.
Where can the Vesicouterine pouch be found?
The vesicouterine pouch can be found between the bladder and the uterus
This pouch in the female can be acessed by the posterior fornix
The rectouterine pouch, a space found between the uterus and the rectum.
What are the branches off of the anterior devision of the internal iliac artery?
Umbilical artery: Superior vesicular and in some cases blood supply to ductus deferens.
Obturator Inferior vesicular Middle Rectal Internal pudendal Inferior gluteal Uterine (Vaginal)
What are the branches from the posterior devision of the internal iliac artery?
Iliolumbar
Lateral sacral
Superior Gluteal
What are the branches of blood that pass off the external iliac?
Deep circumflex iliac vessels
And the inferior epigastric vessel
Where do the gonadal arteries (testicular/ ovarian) come from?
Directly off the abdominal aorta.
