Image of male reproductive system
Where do the urinary system and reproductive system intersect in men?
In the prostatic part of the urethra
What ability do sperm cells gain when they are moved through the epididymis?
The ability to mov eand fertilize an egg
What store sperm cells until ejaculation?
Epididymis
What is the process in which sperm are produced from male primordial sperm cells, by way of mitosis and meiosis?
Spermatogenesis
Where does spermatogenesis take place?
The thin seminiferous tubules
Diagrams of the testis
Where do sperm cells acquire their tails (which give them motility)
Epididymis
What are the major components of the female reproductive system?
Ovary (on each side)
Uterus, vagina and clitoris in the midline
What does the uterus lie between?
Bladder and rectum in the midline
Name for early stage of an embryo, produced by cleavage of an ocum. It’s a liquid-filled sphere whose wall is composed of a single layer of cells
Blastocyst
Name for the inferior part of the uterus
Cervix
What is the site of egg production?
Ovaries
Where are mature eggs ovulated into?
the periotoneal cavity, directed into the adjacent openings of the uterine (fallopian) tubes
Like testes in men, the ovaries develope ______________________ and then _____ before birth bringing with them their vessels, lumphatics and nerves
high on the posterior abdominal wall
descend
Unlike the testes, the ovaries do not __________. Instead they stop short an dassume a position on the lateral wall of the pelvic cavity
migrate through the inguinal canal into perineum
Where does fertilization normally take place?
Ampulla
What is another name for the rectouterine pouch and wher eis it situated?
Pouch of douglas
situated between rectum and uterus
What site does infection and fluids typically collect?
Pouch of douglas
How is an abscess in the pouch of douglas typically dealt with?
Drainage through vagina or rectum
Where does the right ovarian artery branch directly from? Where does it empty into?
Branches directly from the aorta and the right renal vein. Empties into inferior vena cava
Where does the left ovarian artery branch from? Where does it drain into?
Branches directly from aorta, but the left voarian vein enters the left renal vein which then drains into vena cava.
Turbulence from blood flow in and out of kidney
Why are sympathetic fibers important (T10-L2)?
Move secretions from epididymis and associated glands into urehtra to form semen during ejaculation
What is a major function of the parasympathetic fibers?
Stimulate erection
What causes infertility?
A blockage of fallopian tubes, or uterus abnormalities
What is the most common congenital uterine abnormality? Band blocks uterus into two sections
Septate uterus
