Do you understand the role and function of the labia minora and labia minora? What are the physiological functions of the labia minora

The labia is a component of the female reproductive organs and has a protective effect on adjacent urethral and vaginal openings. So, how much do you know about the physiology of the labia? Let's take a look at the detailed introduction of the article.

Introduction to physiological functions of the labia: One of the components of female organs is the labia, which is two pairs of lip shaped tissues surrounding the vaginal opening. The larger pair on the outer side is the labia majora, and the smaller pair on the inner side is the labia minora. They (especially the labia minora) are very sensitive to sexual stimulation

The labia minora is a part of the female external genitalia, a pair of longitudinal skin mucosal folds located between the labia minora on both sides. The labia minora is soft and free of subcutaneous fat, with abundant sebaceous and sweat glands. The surface is moist and smooth without hair. There is a rich distribution of nerves under the mucosa, and the sensation is very sharp.

The labia minora is thin, and its size and shape vary from person to person. Some asymmetry, large and small, is normal. Unmarried and married women, the closure of the labia minora serves to protect the vagina and internal genitalia, and is a part of women's natural defense function.

The front end of the labia minora merges with each other and is divided into two leaves. The front leaf wraps around the penis to form the foreskin, while the back leaf forms the penile frenulum. The posterior end of the labia minora combines with the posterior end of the labia majoris, forming wrinkles in the midline and forming a frenulum of the labia, which is prone to tearing during childbirth.

The labia minora is located on the inner side of the labia minora and is also a skin wrinkle. There is no growth of pubic hair on it, and the surface is smooth and delicate, with rich elasticity. It is mostly light red, moist like mucosa, and distributed in sebaceous glands. Subcutaneously, there are blood vessels, elastic fibers, and a small amount of smooth muscles, with abundant nerve distribution and keen sensation. There are significant individual differences in the shape and size of the labia minora. Some people have narrow labia minora, while others have long labia minora that hangs down to the outside of the labia majora. Some are very thick, some are very thin, some are as large as irregular umbrella shaped nail caps, and some are like typical semicircles. Some people have a light red color, some people have a brownish red color, and some people have two colors for their labia minora: the outside is brownish black, and the inside is pink. Generally speaking, its color will deepen with age and the number of deliveries. Some women in African tribes take pride in the length of their labia minora and have been using it since childhood. As adults, their labia minora is thick and long, reaching high above the labia minora, but its size has no significant impact on sexual response.
