We dissected sheep testicles today. They were lovely specimens and an interesting tissue to dissect, being so dense.
We first looked at the outer appearance and noted the shiny outer testis. Exiting at the upper end is the epididymis head. The tail of the epididymis leading to the vas deferens or sperm tube is pressed against the ball sac all the way down then up again to the top. Here we have cut through the thin membrane that attaches it to the testis and released it. We can see the associated blood vessels.
We cut into the testis and removed the outer tunica like a bag. It was a very shiny, smooth and tough tissue with no elasticity.
Finally we cut into the testicular tissue. When we divided it we could see the lobes or septate nature of the seminiferous tubules.
