EXTERNAL ORGANS

The female pudend (vulva) constitutes the outer part of the female genitals.

Fundamentally, it is represented by a large anteroposterior spindle-shaped spindle opening, with very rugged edges, and situated on the perineum, immediately behind the symphysis of the pube.

As a frame for this fusiform opening, we find two protruding, rounded edges that describe a semi-arch on each side, lateral convexity, lateral convexity and named after Larger Lips of Pudding.

Pudding's Bigger Lips

The larger lips unite anteriorly, near the symphysis of the pube, forming an acute angle called Previous Commissioning.

The same happens later, in the center of the perineum, constituting the Later Commissioner.

Posterior and Anterior Commissure

Due to the anterior commissure of the larger lips of the female pudendal and in relation to the symphysis of the pube, there is an accumulation of adipose tissue in the subcutaneous mesh, determining a protrusion at this level, elevation that is called Pubis Hill.

The skin of Monte da Pube has a large amount of hair, which becomes scarcer in the region of the larger lips of the pudendum.

The anteroposterior slit that is determined by the two larger lips is called the pudendo rhyme.

The anterior 1/3 has a posterior median triangular protrusion of the posterior base, it is called the clitoris glans and the covering skin roof would be the foreskin of the clitoris.

The clitoris It is a miniature of the male penis. Like this one, it is an erectile organ. The clitoris is formed by a spongy tissue called the corpora cavernosa, which can fill with blood.

Clitoris

The cavernous body of the clitoris originates from two rather long branches (right and left), which collapse medially and then inferiorly to the inferior (right and left) branches of the pube, joining at the level of the center of the pube symphysis. the body of the clitoris, which runs obliquely forward and downward, ending in a dilation which is the glans of the clitoris.

Each branch of the corpora cavernosa is surrounded by an ischiocavernous muscle.

As we said, the skin fold that surrounds the body of the clitoris is called the foreskin of the clitoris.

The posterior 2/3 of the area bounded by the largest are occupied by another but smaller fusiform formation.

Limiting this smaller fusiform area we find on each side a laminar fold, which together constitute the smaller lips of the female pudend.

The Smaller Lips they are parallel to the largest, coinciding at the posterior commissure, but joining anteriorly, at the level of the clitoral glans.

Smaller Lips

Each smaller lip is semilunar, tapering at the extremities.

The space (fusiform) between the smaller lips is called Foyer from the vagina.

In the depth of the base of implantation of the smaller lips and therefore, on each side of the highest part of the vagina vestibule, we find another spongy formation, called the vestibule bulb.

Each bulb of the vestibule (bulb of the vagina) is surrounded by its bulbocacernous muscle.

Immediately behind the posterior end of each vestibule bulb is a spherical gland approximately the size of a pea grain called the larger vestibular gland. The ducts of these glands (right and left) will open at the base of the corresponding smaller lip.

Medium in the atrium of the vagina are two openings. An anterior, small, is the external ostium of the urethra. The median opening that lies posteriorly in the vagina atrium is the ostium of the vagina.
