Coloured SEM of a seminiferous tubule
Numéro d’image : 11873685
| Testis. Coloured scanning electron micrograph showing a cross section of a seminiferous tubule within a testis. This is the site of production and maturation of sperm. The tubule is surrounded by a basal lamina (pale orange) which separates it from other seminiferous tubules. Round undifferentiated cells (blue-purple) line the tubule wall; they will halve their chromosome number and become mature spermatozoa (centre with tails) in a process which takes about two months. Mature sperm then migrate from the tubule to the epididymis where they are stored. Magnification: x590 at 6x7cm size | |
