Explanation The penis is present in front of the scrotum and has a cylindrical shape. It passes out both the semen and urine from the body in males. It is a muscular organ that has some erectile tissues. The first two erectile tissues are corpus cavernosum and the third is corpus spongiosum. Corpus spongiosum is present on the ventral side of the penis. The corpus spongiosum encloses the tube, which passes the urine and semen...

Chapter 26, Problem 4TYC

Students have asked these similar questions

Suppose the corpus spongiosum became as engorged with blood as the corpora cavernosa do during erection of the penis. What problem would this create for sexual function?In light of this, why is it beneficial that the corpus spongiosum is not enclosed in a tunica albuginea?

An inability to contract the ischiocavernosus and bulbospongiosus muscles would interfere with which part of the sexual response in males?

Sexual arousal results in a generally positive sympathetic response, e.g. increased heart rate, increased breathing rate and depth, etc. How is it, then, that erection can occur if sympathetic activity causes vasoconstriction and prevents blood flow into the vascular spaces of the penis?
