Finals | Mastery of REPRODUCTIVE SYSTEM with Radiologic Correlation Flashcards
GENERAL DIVISIONS OF REPRODUCTIVE SYSTEM ACCORDING TO FUNCTIONS
- GONADS
- SYSTEM OF DUCTS
- ACCESSORY SEX GLANDS
- SUPPORTING STRUCTURES
Produce gametes (reproductive cells) and sex hormones
GONADS
SYSTEM OF DUCTS Function
Passageway/ transportation
Temporary storage
ACCESSORY SEX GLANDS Function
Produce substances that protect and facilitate movement of gametes
SUPPORTING STRUCTURES Function
Assist in the delivery of gametes
FEMALE: assist in the delivery of fetus
Produce sperm cells
Secrete testosterone
TESTES
Epididymis PLURAL FORM
Epididymides
Organ closest to testes
Epididymis
Site for sperm maturation
Epididymis
Process by which sperm acquire motility and the ability to fertilize an ovum
sperm maturation
Sperm maturation occurs for about how many days?
14 days
Propelling of sperm from the epididymis to vas deferens
Peristalsis
Sperm will be stored here even after it has already matured until it is needed
Epididymis
Expanded end of vas deferens
Ampulla of vas deferens
Other therm for vas deferens
Ductus deferens
Formed by the union of the duct from the seminal vesicle and the ampulla of the ductus (vas) deferens
Ejaculatory duct
Ejaculatory duct passes through the —
prostate gland
Terminates in the prostatic urethra, where they eject sperm and seminal vesicle secretions just before the release of semen
Ejaculatory duct
Passageway for both semen and urine
Urethra
Urethral parts
Prostatic urethra
Intermediate (membranous) urethra
Spongy urethra
Produces alkaline viscous fluid directed to the ejaculatory duct
Seminal vesicles
Common structure seen to identify prostate gland
UB
Location of prostate gland in relation to UB
Prostate gland is inferior to UB
Other term for bulbourethral glands
Cowper’s glands
What comprises of the semen?
Sperm + Seminal fluid
Protects and supports testes
Scrotum
Houses urethra
Penis
Pouch between the anal canal and seminal valve
Rectovesical pouch
DIlated end part of the urethra (normal)
Navicular fossa
Expanded part of penis
Glans penis
Margin of glans penis
Corona
Tissues that make up the penis
Corpus spongiosum
Corpus cavernosum
Internal compartments between testes
Lobules
What are inside the lobules?
Seminiferous Tubule
Produce egg cells
Secrete progesterone and estrogen
OVARIES
Route for sperm to reach an ovum and transport secondary oocytes and fertilized ova from the ovaries to the uterus
FALLOPIAN TUBE
Other terms for FALLOPIAN TUBE
UTERINE TUBE
OVIDUCTS
Pathway of sperm to reach egg cell
UTERUS (WOMB)
Site for implantation of fertilized egg
UTERUS (WOMB)
Posterior end part of uterus
Cervix
Outlet for menstrual flow and passageway of childbirth
VAGINA
Where is the vagina located?
Between UB and rectum
Protects internal part of the reproductive system, especially openings
Vaginal folds
1. Labia Majora
2. Labia minora
Opening for sexual arousal (FEMALE)
Clitoris
Fluid-filled fallopian tube with dilation
HYDROSALPINX
Examines fallopian tube and uterus
Hysterosalpingography
One indication of Hysterosalpingography
Infertility in females
- CM is inserted into the uterus; flows to the fallopian tube. If no blockage, CM is spilled into its peritoneum
TRANSABDOMINAL PELVIC UTZ vs TRANSVAGINAL PELVIC UTZ
TRANSABDOMINAL
- Transducer on top of the abdomen
- Smaller appearance of ovaries
- Downward appearance of fan
TRANSVAGINAL
- Transducer inserted in the vagina
- Larger appearance of ovaries because transducer is nearer the pelvis thus, enlarged
- Upward appearance of fan
When can’t transvaginal pelvic utz be used?
Cannot be used if the patient is a virgin. Instead, a transrectal pelvic utz is used where the transducer is inserted through the rectum
Multiple follicular cysts present in the ovary
PCOS
How many number follicles for it to be considered PCOS?
> 12
Consists of cells to help maturation. Once ready for fertilization, it will break to release follicles
Ovarian follicle
- More active compared to other follicles
- Faster to develop
- Cells within mature faster
DOMINANT FOLLICLE
Lining of uterus
Endometrium
Appearance of Endometrium in an UTZ
Hyperechoic compared to the rest of the uterus
Best imaging modality for examining a fetus
UTZ
UTZ is used in fetal babie sto determine what?
- Size of the baby
- How old is the baby in months
- Baby’s gender
Most common type of tumor in testes
SEMINOMA
SEMINOMA appearance in an UTZ
Hypoechoic
An UTZ procedure performed by doctors most of the time
SCROTAL UTZ
Inserted through the uterus to prevent pregnancy
INTRAUTERINE CONTRACEPTIVE DEVICE
Inflammation of the epididymis and testis
EPIDIDYMO-ORCHITIS
UTZ technique that Usually looks at blood flow
Color Doppler Technique:
How to determine fetal demise is an utz?
Spalding sign
Spalding sign appearance
Overlapping of the fetal skull because the brain has already collapsed
An example of uterine duplication anomaly
BICORNUATE UTERUS
Multiple deposited calcification within the testis
MICROLITHIASIS
MICROLITHIASIS appearance
Hyperechoic
Procedure that uses radioactive seeds placed on the prostate gland responsible for producing ionizing radiation where cancer is present
Brachytherapy
Responsible for producing ionizing radiation directly where the cancer is present
Radioactive seeds
