29- Pelvic Viscera #1 & #2 Flashcards
(95 cards)
These muscular tubes are retroperitoneal organs. They are approximately 10” long and enter the pelvis minor by passing over the pelvic brim just anterior to the internal iliac vessels.
Ureters
In the male, the _______ _______ crosses the ureters. While in the female, the _______ _______ crosses over the ureter.
Ductus Deferens
Uterine A.
The ureters enter the wall of the ________ at its posterosuperior angle. In the male, this angle is immediately above the seminal vesicles and inferior to the ductus deferens.
Bladder
The intramural portion of the ureters, in the wall of the urinary bladder, forms a one-way flap _______ tat prevents retrograde flow of urine.
Valve
________ in the urethras moves urine from the kidneys to the bladder.
Peristalsis
The ureters are abundantly supplied with neurons that detect pain. These pain fibers reach the spinal ganglia and spinal cord levels ________. Pain from the ureters is referred ipsilaterally to the _______ _______ _______ and _______.
T10-L2
Lower Abdominal Quadrant
Groin
This sac is very distensible, containing three layers of smooth muscle in its walls. Its size, shape, position, and relationships vary with the amount of urine it contains.
Urinary Bladder
The mucosa of the urinary bladder is very loosely attached, except at the neck of the bladder in an area known as the ________.
Trigone
The sac of the urinary bladder is located in the anteroinferior part of the pelvis minor, below the peritoneum, resting on the pelvic diaphragm. As it fills, it ascends into the abdomen elevating its peritoneal covering with it. How could we obtain a urine sample because of this?
It’s possible to get a urine sample from a filled bladder by inserting a hypodermic needle just above the pubic symphysis in the midline (without entering abdominal cavity).
In the male, the superior surface of the urinary bladder is covered by peritoneum and the base is posterior. The base is separated from the rectum by what?
Vas Deferens
Seminal Vesicles
This is a peritoneal recess in males that partly separates the bladder from the rectum.
Rectovesical Pouch
In males, the apex of the bladder is anterior while the neck is where it junctions with the _______ and rests upon the _______ _______.
Urethra
Prostate Gland
In males, within the neck of the bladder there is an _______ _______ _______ composed of smooth muscle that guards the opening of the urethra called the _______ _______ _______. This prevents the retrograde flow of semen into the bladder during ejaculation.
Internal Urethral Sphincter
Internal Urethral Orifice
***Female bladder does NOT contain sphincter!
In females, what lies posterior and superior to the bladder?
Superior = Body and Fundus of Uterus
Posterior = Vagina and Uterine Cervix
In females, a peritoneal pouch called the ________ ________ is located between the superior surface of the bladder and the uterus.
Vesicouterine Pouch
In females, the neck of the bladder is held in position by what ligaments?
Pubovesical Ligaments
In males, the neck of the bladder is held in position by what ligaments?
Puboprostatic Ligaments
The lateral surfaces of the bladder are surrounded by the vesical fascia, which contains the…
Vesical Venous Plexus
In males, what is included in the trigone area of the bladder?
Internal Urethral Orifice
Two Ureteric Orifices
What are the four parts of the male urethra?
1) Intramural portion in bladder wall
2) Prostatic urethra
3) Membranous urethra
4) Spongy (penile) urethra
The male urethra has four parts and totals 6-8 inches in length. This part is common to both males and females and passes through the bladder wall.
Intramural Portion
In males, the intramural portion contains what?
Internal Urethral Sphincter
The second part of the male urethra is approximately 1 inch long and passes through the _______ _______.
Prostate Gland
***Called the Prostatic Urethra
The Prostatic Urethra is the widest and most dilatable portion of the entire urethra. On the posterior wall is a longitudinal ridge called the _______ _______. On each side of this ridge is a groove called the _______ ______.
Urethral Crest
Prostatic Sinus
