Q7. Starting at the testes, indicate the pathway taken by sperm during ejaculation – list all the relevant structures and glands

The pathway taken by sperm during ejaculation involves several structures and glands. Here is the step-by-step process:

1. Testes: The journey begins in the testes, where sperm are produced.

2. Epididymis: Once the sperm are produced, they move to the epididymis, a long, coiled tube that rests on the backside of each testicle. It's a place where sperm mature and are stored.

3. Vas Deferens: The mature sperm then travel through a tube called the vas deferens.

4. Seminal Vesicles: The vas deferens leads to the seminal vesicles, which produce a sugar-rich fluid (fructose) that provides sperm with a source of energy and helps with their motility. This fluid makes up most of the volume of a man's ejaculatory fluid, or ejaculate.

5. Prostate Gland: The sperm and seminal vesicle fluid travel through the prostate gland, which produces a fluid that protects the sperm and aids in their transportation. This fluid combines with the sperm and seminal vesicle fluid to form semen.

6. Urethra: The semen then travels through the urethra, the tube that carries urine and semen out of the body through the penis.

7. Penis: The semen is finally ejaculated out of the body through the penis.
