Which statement accurately describes the process of ejaculation?
Understand the Problem
The question is asking for the accurate description of the process of ejaculation, requiring knowledge of human physiology and reproductive biology.
Answer
Ejaculation involves two phases: emission, where sperm is moved to form semen, and expulsion, where semen is expelled.
Ejaculation is a physiological process consisting of two main phases: emission and expulsion. During emission, sperm are moved from the testes and epididymis to the urethra, forming semen. In the expulsion phase, semen is forcefully expelled out of the urethra.
Answer for screen readers
Ejaculation is a physiological process consisting of two main phases: emission and expulsion. During emission, sperm are moved from the testes and epididymis to the urethra, forming semen. In the expulsion phase, semen is forcefully expelled out of the urethra.
More Information
The process is controlled by the autonomic nervous system, ensuring the proper sequence of muscle contractions.
Tips
Confusion may arise between emission and expulsion phases. Remember that emission is about moving sperm to form semen, while expulsion is about ejecting semen from the body.
