Female & male reproductive systems Flashcards
What do the female and make reproductive systems consist of?
Glands and tubes that produces and nurture sex cells and transport them to the site of fertilisation
Male sex cells
Sperm
Female sex cells
Oocytes
Primary sex organs term
Gonads
Other organs ( other than gonads) in the reproductive system term
Accessory organs
What’s the spermatic cord that suspends the testes?
Scrotum
What cells give rise to sperm cells?
Spermatogenic cells
What tubules have an epithelium lined with spermatogenic cells?
Seminiferous tubules
What cells between the seminiferous tubules produces male hormones?
Interstitial cells
At what stage are sperm cells undifferentiated?
In the male embryo
What are undifferentiated spermatogenic cells called?
Spermatogonia
What cells in the seminiferous tubule nourish and regulate spermatogenic cells?
Sustentacular cells
Hormones in embryo development cause sperm cells to undergo…
Mitosis
How many types of cell does mitosis of spermatogonia make?
2
What two functions do the product cells of mitosis of spermatogonia cells do?
Type one remains a spermatogonial cell and continues to undergo mitosis
Type two becomes a primary spermatocyte and undergoes meiosis
Term for sperm production
Spermatogenesis
What cells are the products of meiosis from spermatocytes
Haploid, secondary spermatocytes
What’s the products of the division of secondary spermatocytes?
Spermatids
Where do sperm mature?
Epididymis
What is at the top of the sperm cell head?
Acrosome
What is the acrosome at the top of the sperm cell head?
A bag of digestive enzymes to help erode tissues around the female egg
Tail of sperm cell
Flagellum
What is contained in the mid-piece of a spermatocytes cell?
Mitochondria
What is contained in the sperm cell head?
Haploid nucleus
What are the male internal accessory organs?
Several ducts
Urethra
prostrate gland (and others)
Seminal vesicles
What are the epididymides
Coiled tubes adjacent to the testes from the testes to the vas deferens where sperm matures
Ductus deferens
Muscular tube from epididymis up to the ejaculatory duct
Seminal vesicles
Saclike structure attached to the vas deferens near base of urinary bladder
What do seminal vesicles do
Secrete fructose to nourish sperm
Secrete prostaglandins to cause muscular contractions in female tract to help propel sperm to the egg cell
Prostate gland location
Surrounds urethra at base of bladder
Prostate gland function
Secreted thin milky fluid containing citrate which nourishes sperm and prostate specific antigen to help liquefy sperm
Bulbourethral gland location and function
Small structures inferior to the prostate
Secrete mucus to lubricate tip of penis during sexual arousal
Semen
Combination of sperm and secretions from seminal vesicles and prostate and bulbourethral glands
