Sexual Reproducotion In Humans Flashcards
Waht are the forum and parts of the male reproductive systems
There are 4 mai n parts of the Malay reproductive system and theses are :
The penis whcih the urethra runs trhrough
A pair off testes (taht contained could tubes taht are called the smeinifourous tubules dang he are lined with germinal epithelial cell adn taht adre diploid ) are held in a n external sac called the scrotum
Ducts(‘the ejaculatory duct and the vas deferens ) whcih connect the testes to the penis
Accesssory glass thes are the coppers gland with oh so just behined the the prostate , the prostrate gland and then the seminal vesicle
The coworkers gland secretes alkaline secretion and the the prostate gland secrete zinc containing prostate fluid whcih mixes with the mucus and form the seminal vesicle to produce semen on ejaculation the sperm pass from the empoidrydmis whcih is where the sperem develop motility the seminal vesicle produces mucus containing fructose the fructose is issued as the main energy dosurce and is required by the sperm for respiration to precise atp used for movement the secretion made are alkaline and these help to msinitain mobility the help nourish the sperm becaseu rthe contain fructose whcih sth email energy source as well as amino acids and and zinc
They also help to nucteslismeth acidity of the caginla tract as well as the acidity of the urethra form the urine
So fist the germinal emptyeroial cells understood spermstigenisis and the the sperm pass in the lumen of the seminifourose tubules the move through the tubule and collect in the vas efferetia theses perms are then passed in the the empididymis where ther sperm gain mobility
Then on ejaculwti0n rhe sperms pass in the the vas differens form the head of the epididymis adn o ver here the seminal vescisle secretes mucus coinrsinibf fructose whcih is refluxed by the -serenity for motility then these pads sin trey the ejaculatoyr duct where the prostat gland secretes sic containing protate fluid this smites with the sperm and the mucus to create seamen whcih is then passed throruh the ureathra
Waht are the three main parts of the sperm
Head contains the cell memebrane with is made up of cholesterol and glycoproteins across one - lysosome and contains digestive enzymes in this case enzymes that are enquired during fertillisation and the nucleus
Mid piece - the centrioles as well as lost of mitochondria whcih are required for repiration and the prodcutoopfp appt to allow for the movement and growth of the sperm
Tail - contain tha axial fillament
The mitrochondira spiral around the micro tubules that extend for the centriole to he the axial fillament ;
Fertillisation can only occur if ca-citation has occurred so where there are lots of different sperms around the 2 oocyte only the only on that can allow fertillsation to occur is on that is caapciated
