Reproductive System Test 3


Terms in this set (...)

What are the parts of the female reproductive system?
-Uterine Tubes (AKA Fallopian Tubes)
-External genitalia (vulva) (labia minora, vestibule- space where urethra (Anterior) and vagina (Posterior) open
-Mammary Glands
What are the parts of the male reproductive system?
-Series of ducts (vas deferens, epididymus, urethra)
-Accessory glands (seminal vesicles, prostate gland)
-Supporting structures (scrotum-houses the testes, penis-houses the urethra)
What are the testis?
-2 testes residing in the scrotum
-Produce spermatozoa (Exocrine function) and testosterone (Endocrine function)
What is the epididymus? What are its parts?
-Comma shaped structure on the posterior surface of the testes
-Facilitates storage and maturation of the spermatozoa in the tail
-Its parts are the head, body and tail
How are the testis attached to the pelvic wall?
By the spermatic cord
What is the spermatic cord and what does it contain?
-Protects vessels, nerves and lymphatics
-Testicular Artery
-Genitofemoral Nerve
-Ductus (Vas) Deferens
-Pampiniform Plexus of Veins
What is the ductus (vas) deferens?
-Muscular tube extending from the tail of the epididymus to the ejaculatory duct (in the pelvic cavity)
What is part of the lining of the spermatic cord? What does it do?
-Cremasteric muscle
-Not part of the spermatic cord its part of the lining of it
-Assists with the lower and raising of the testes
Contracts when cold
Relaxes when warm
What are the landmarks in relation to the contents of the male/female pelvis?
-Pubic Bone (Anteriorly)
-Sacrum and Coccyx (Posteriorly)
Where does the urinary bladder sit in relation to the pubic bone?
What are the seminal vesicles?
-2 seminal vesicles (Right and Left)
-Located posterior to the bladder and anterior to the rectum
-Superior to the prostate gland
-Secretes a thick alkaline fluid (seminal fluid) that nourish and protects sperm
What is the ejaculatory duct?
-Formed by the union of the ducts of the seminal vesicles with the ductus vas deferens
-Travel anterior/inferior through the posterior aspect of the prostate gland to then dumps its contents into the urethra
What is the prostate gland?
-Walnut size gland
-Sits inferior to the bladder and seminal vesicle
-Surrounds the prostatic part of the urethra
-Secretes prostatic fluid which constitutes about 20% of semen
What are the 3 parts of the male urethra?
-Prostatic urethra (Located in the Prostate)
-Membraneous urethra (Located in the urogenital diaphragm)
-Spongy (penile) urethra (Located in the penis)
-Serves functions in both reproduction and urinary systems
What are the ovaries?
-Paired organs that produce ova (Exocrine function) and estrogen and progesterone (Endocrine function)
-Attached to the lateral pelvic wall by the suspensory ligament in the uterus by the ovarian ligament
What is the uterus?
-Pear shaped hollow muscular organ that protects and nourishes a developing fetus
-Held in the place by the suspensory ligament and the broad ligament (main ligament that wraps around and keeps the uterus in place)
What are the parts of the uterus?
-Fundus (Large rounded part superiorly)
-Body (Between the fundus and the cervix)
-Cervix (Narrow part inferiorly)
What is the position of the uterus?
-Anteverted and anteflexed position
-Sits on top of the bladder (Superior)
-Anterior to the rectum
What are the uterine tubes?
-AKA fallopian tubes and oviducts
-Paired tube that extend from each side of the uterus (Laterally) and open as fimbriae adjacent to each ovary
-Fimbriae receives ova released by the ovary
-Fertilization takes place here
Where is the Pouch of Douglas (Recto-uterine pouch) located?
-Space posterior to the uterus and anterior to the rectum
-Between uterus and rectum
What is the vagina?
-A (canal) tube extending from the uterus (specifically the cervix) to the outside of the body
-Female organ of copulation and allows for menstrual flow and childbirth (Also receives sperm)
What is the prolapse of the uterus?
-In multiparous women and in old age, the ligaments holding the uterus and its normal anteverted and ante flexed position become weak allowing the uterus to descend into the vagina
-In some cases, the uterus can be seen completely out of the pelvis
-The bladder and the rectum can also be affected
During a hysterectomy, what can occur?
-Hysterectomy is the surgical removal of the uterus
-While ligating the uterine artery, the uterer may be accidentally injured. If it is ligated (tied), the kidney may be permanently damaged. If cut, it may end as a fistula.
-Early recognition allows the knot to be released of the tear repaired.
What are the external anatomical landmarks of the breast?
-Areola (darkened region surrounding the nipple)
What are the internal features of the breast?
-15-20 glandular lobes which contain fat (Contributes to the shape and size)
-Lactiferous ducts and sinuses (Important for lactating and where milk is ejected)
-Coopers (Suspensory) ligaments (Support and hold the breast in place) Droopy boobs :)
