Question

Which tissues are primarily responsible for engorgement and rigidity during penile erection?

विकल्प

• The corpus spongiosum and the prepuce together

• The glans penis and its sensory nerve endings

• The two paired columns known as the corpora cavernosa

• The blood vessels surrounding the urethra

Answer 1

The corpora cavernosa are two paired columns of erectile tissue that run along the length of the penis and are the primary tissues responsible for engorgement and rigidity during erection. When blood fills the sinuses within these tissues, the penis becomes rigid, enlarged, and capable of penetration during sexual intercourse.
