Study Notes
Functions of the Scrotum and Testes
- The scrotum regulates the temperature of the testes, which is necessary for sperm development, as it maintains a temperature slightly lower than the body's core temperature.
Cell Functions in the Testis
- Sertoli cells provide support and nutrition to developing sperm cells, and also facilitate the release of mature sperm into the tubular network.
Hormone Synthesis
- Leydig cells synthesise and secrete testicular hormones, such as testosterone, into the bloodstream.
Male Sex Accessory Ducts
- The epididymis is located along the posterior surface of each testis, and it stores and transports mature sperm cells.
Testicular Functions
- Leydig cells play a crucial role in the testis by producing and secreting testosterone, which is essential for the development of male characteristics and reproductive organs.
Meiosis and Sperm Development
- Male germ cells undergo meiotic divisions in the seminiferous tubules, which are located within the testis.
Epididymis Connection
- The rete testis, a network of tubules, opens into the epididymis, allowing mature sperm cells to be transported out of the testis.
