faza foliculara

Answer 8

400000 folic primoridali
ovocit primar inconj de un singur strat de cel folic epiteliale plate = granuloase
300-400 folic se maturizeaza

maturizarea folic are loc

Answer 9

prin 3 stadii succesive
concomitent cu faza ovogenetica

Question 10

folic primar

Answer 10

evolueaza sub act FSH
forma sferoidala plina =stadiu folic preantral

zona pellucida = mb retractila semipermeabila cu capacitati de transport

Question 13

foliculul secundar

Answer 13

devine cavitar prin confluenta micilor spatii formate in int =spatiu antral
cav excentrica = antru folicular

=de Graaf
corespunde stadiului folicular preovulator
15-25mm
cant crescuta de lichid folicular
ovocit secundar !!!!(prima diviziune mitotica)
se initializeaza luteinizarea si prod progesteron

act dehiscenta a enzimelor proteolitice
secretia de prostaglandine
vasodilatatie locala
elem contractile perete folicular

Question 23

ovulul ovulat

ovocit secundar in div meiotica 2
desprns de pe cumulus oophorus
devenit liber

se hipertrofiaza
acum pigment lipidic galben =luteina
devin secr de progesteron
