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 testes are covered by three protective coverings called tunicae. They are externally covered by tunica vaginalis, the next is a white fibrous membrane called tunica albuginea and the last and innermost is tunica vasculosa.

Detailed explanation-4: -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-5: -Scrotum: a loose sac of skin containing the testes and located inferior to the base of the penis. Scrotal skin has small elevations (rugae) on the surface and is more pigmented than the remainder of the body, irrespective of ethnic background, although this distinction is more obvious in individuals with a dark skin.
