Genitourinary Flashcards
Muscles of the Pelvic diaphragm of the Pelvic Floor
Levator ani: pubococcygeus, puborectalis, iliococcygeus, and coccyges (ischiococcygeus)
Muscles of the Urogenital diaphragm of the Pelvic Floor
Deep transverse perineal, urethrae sphincter
Muscles of the Urogenital triangle of the Pelvic Floor
Female: bulbocavernosus, ischiocavernosus, superficial transverse perineal
Male: bulbospongiosus, ischiocavernosus, superficial transverse perineal
Prostate
- Internal organ lying inferior to the bladder
- Produces and secretes fluid to combine with sperm, seminal vesicle fluid, and bulbourethral gland fluid to create semen
Kidneys Function in the Renal System
*Remove water, salt, and metabolic waste from the blood through excretion of urine
* Contribute to homeostasis including: acid-base balance, regulation of electrolyte concentrations, control of blood volume, and regulation of blood pressure through the control of hormones secreted into the bloodstream
Ureters Function in the Renal System
- Muscular tubes connecting the kidneys to the urinary bladder to transport urine
Urinary Bladder Function in the Renal System
- Muscular tube for excretion of urine
- Semen transport during ejaculation in males
Which hormone, produced by the hypothalamus, stimulates the kidneys to conserve water?
Antidiuretic hormone
When blood pressure falls to dangerously low levels, antidiuretic hormone (ADH) helps to restore arterial pressure by causing intense vasoconstriction.
Skeletal muscle that surrounds the urethra as it extends through the pelvic floor is known as the:
external urinary sphincter
There are two urethral sphincters, specifically the internal and external urinary sphincters. The external urinary sphincter provides a second means of stopping the escape of urine from the body. This sphincter is under voluntary control.
The structure that connects the kidney to the urinary bladder is the:
ureter
The ureter is a tube that carries urine from the kidney to the urinary bladder. There are two ureters, one attached to each kidney. The upper half of the ureter is located in the abdomen and the lower half is located in the pelvic area.
What is the name of the male sex gland that surrounds the neck of the bladder and the urethra?
Prostate
The prostate is a gland within the male reproductive system that is located just below the bladder. The chestnut-shaped prostate surrounds the beginning of the urethra and makes fluid that is a component of semen.
What reflex stimulates the impending need to urinate when the bladder is filling?
vesical reflex
The vesical reflex refers to the sensation of a need to urinate when the bladder is moderately distended.
Anuria:
- Inadequate urine output in a 24-hour period;
- less than 100 mi (e.g., severe dehydration, shock, end-stage renal disease).
Benign prostatic hypertrophy:
- A non-cancerous enlargement of the prostate gland that is progressive.
- Common in males over 60 and can interfere with normal voiding.
Cystocele:
Bulging of the bladder into the vagina.
Ectopic:
- Implantation of a fertilized ovum outside of the uterus.
- The fallopian tube is the most common site of an ectopic pregnancy.
Endometrium:
The inner lining of the uterus that is shed monthly in response to hormonal influence.
Glomerular filtration rate:
- An estimate of the filtering capacity of the kidneys;
- volume of filtrate produced per minute by the kidneys.
Glomerulus:
The specialized tuft of capillaries that are needed for the filtration of fluid as blood passes through the arterioles of the
kidneys.
Hematuria:
Presence of blood in the urine (e.g., cancer, faulty catheterization, serious disease).
Impotence:
Impairment with ejaculation, orgasm, erection, and/or libido.
Myometrium:
The muscular outer layer of the uterus.
Nephrolithiasis:
The condition of developing kidney stones. There are various types of crystal formations that create stones.
Nocturia:
Urinary frequency at night (e.g., diabetes mellitus, congestive heart failure).
Oliguria:
Inadequate urine output in a 24-hour period; less than 400 ml (e.g., acute renal failure, diabetes mellitus).
Polyuria:
Large volume of urine excreted at one time (e.g., diabetes mellitus, chronic renal failure).
