The raised rim on the border of the shaft and glans is named the corona. The three cylindrical bodies of spongy tissue, that are full of blood vessels, run alongside the size of the shaft. The penis consists of nerves, blood vessels, fibrous tissue, and three parallel cylinders of spongy tissue. During arousal, these our bodies erect the penis by filling with blood.
The penis supplies a passageway for sperm and urine. The expanded finish is the ampulla, which shops sperm earlier than ejaculation. These aid urination and ejaculation. Other elements of the penis embrace the shaft, glans, root, cavernous our bodies, and spongy body. The root consists of the expanded ends of the cavernous our bodies, which fan out to form the crura and attach to the pubic bone and the expanded end of the spongy physique. The third, referred to as the corpus spongiosum (spongy body), is a tube that lies centrally beneath the others and expands at the top to type the tip of the penis (glans). The testicles converge to form the seminiferous tubules, coiled tubes at the top and back of each testicle. The third part of the duct system is the ejaculatory ducts, that are 1-inch (2.5 cm)-lengthy paired tubes that move by means of the prostate gland, where semen is produced. Within the scrotum, the testicles are held away from the physique, one attainable reason for this is so sperm could be produced in an atmosphere slightly decrease than normal physique temperature.
