Questions and Answers
¿Qué complejo hormona-receptor modula la diferenciación de los genitales externos masculinos?
¿Qué células se originan en el epiblasto y migran a las gónadas en la quinta semana de desarrollo?
¿Qué gen influye en la proliferación y penetración de los cordones testiculares en la médula para formar los testÃculos?
Study Notes
- Testosterone and dihydrotestosterone bind to specific intracellular protein receptors.
- This hormone-receptor complex binds to DNA to regulate tissue-specific gene transcription.
- Testosterone/receptor complex modulates the virilization of mesonephric ducts.
- Dihydrotestosterone/receptor complex modulates the differentiation of male external genitalia.
- Gonads are undifferentiated until after the 7th week of development.
- Primordial germ cells originate in the epiblast and migrate to the gonads in the 5th week.
- Male gonads proliferate and penetrate the medulla to form testicular cords under the influence of the SRY gene.
- Testicular cords divide into small networks to form the testis.
- The testicular cords are separated from the surface epithelium by a fibrous tissue layer called the tunica albuginea.
- The differentiation of male and female gonads is indistinguishable at the level of the genital ridges.
