GENERAL HISTOLOGY

Detailed explanation-1: -Scrotum. The bag of skin that holds and helps to protect the testicles. The testicles make sperm and, to do this, the temperature of the testicles needs to be cooler than the inside of the body. This is why the scrotum is located outside of the body.

Detailed explanation-2: -The scrotum or scrotal sac is an anatomical male reproductive structure located at the base of the penis that consists of a suspended dual-chambered sac of skin and smooth muscle. It is present in most terrestrial male mammals. The scrotum contains the external spermatic fascia, testes, epididymis, and ductus deferens.

Detailed explanation-3: -The looser skin allows the balls to hang away from the warm body and encourages airflow around the scrotum to keep the area cool. As such, even in younger people, the testicles will typically sag a bit. A person will generally notice this once they start producing sperm during puberty.

Detailed explanation-4: -The spermatic cord suspends the superior aspect of the testes. At the inferior end, the testes are attached to the scrotum by the scrotal ligament which is a remnant of the gubernaculum.

Detailed explanation-5: -The perineum protects the pelvic floor muscles and the blood vessels that supply the genitals and urinary tract. The perineum also protects the nerves used to urinate or have an erection. In males, the perineum is the area between the anus and the scrotum.
