Each seminiferous tubule is lined by male germ cells called:
1. | Spermatogonia | 2. | Primary spermatocytes |
3. | Sertoli cells | 4. | Leydig cells |
The correct sequence of male sex accessory ducts beginning from testis would be:
1. | rete testis → vasa efferentia → epididymis → vas deferens |
2. | rete testis → vas deferens → vasa efferentia → epididymis |
3. | vas deferens → vasa efferentia → epididymis → rete testis |
4. | vasa efferentia → vasa deferens → epididymis → rete testis |
The ducts of the seminal vesicles in humans:
1. | join the vas deferens to form the ejaculatory duct |
2. | open into the ejaculatory ducts which continue into the urethra |
3. | join each other and the common duct opens into the prostatic duct |
4. | transport the stored sperms to the outside through the urethra |
