What is the function of the seminiferous tubules in the testes?
To produce testosterone
To store sperm
To transport sperm to the epididymis
To produce and develop sperm
The seminiferous tubules are a network of small tubes within the testes where sperm production occurs. They contain specialized cells called germ cells, which divide and differentiate into mature sperm cells. These cells undergo a series of complex cellular changes and maturation processes within the seminiferous tubules, including meiosis, which is the process of cell division that reduces the number of chromosomes in each cell. The developing sperm cells are nourished and supported by Sertoli cells, which are another type of specialized cell within the seminiferous tubules.
Once the sperm cells are fully matured, they are released into the lumen of the seminiferous tubules and transported to the epididymis, where they undergo further maturation and storage until ejaculation. Therefore, the primary function of the seminiferous tubules is to produce and develop mature sperm cells.
Option 4 is the correct answer.
