Methodology to measure the length, curvature and the angles of the cardinal and deep uterosacral ligaments. Panel A: 3D models of pubic bone (PB), Sacrum (Sac), Uterus (Ut), Vaginal (Vag) and Cardinal ligaments(CL) and Deep uterosacral ligament (US) in three-quarter view. Panel B: Identification of origin-insertion line and best five curve for the cardinal ligament seen from the back. Red dots are the landmarks identified for origins and insertions. Blue line connects the center of landmarks to establish the line-of-action. The angle between cardinal ligaments was measured as α. Red curve present the best fit curve of the ligaments on the cross-section showed as black line in the bottom. Length of the curve is l and the tangent direction difference was measured as Δ. Panel C: Deep uterosacral ligament line-of-action and best fit curve, angle between deep uterosacral ligament β was measured in axial plane. Panel D: Angles γ between cardinal and deep uterosacral ligament in sagittal plane. The blue lines presents the line-of-action of the ligaments
Four-cable suspension biomechanical model. Left shows the MR-based 3D model of the uterus and vagina and transparent levator ani muscle (blue) with lines of action of cardinal and uterosacral ligaments in the side view. PS: pubic symphsis; Sac: sacrum. Right shows the simplified four-cable load-sharing biomechanical model free body diagram. Pelvic load models the downward tension placed on cervix (Cx) resulting from increasing intra-abdominal pressure and is arbitrarily set to be 1 N and parallel to levator plate direction (levator plate anlge, LPA). This force results in the tension on cardinal ligaments (TcL and TcR) and deep uterosacral ligament (TuLand TuR)
On Wednesday, the songstress noted in a statement that the NFT's purpose was to understand "the concept of creation, not only the way a child enters the world through a woman's vagina, but also the way an artist gives birth to creativity."
Alot of other pussy models were all pretty high poly, wich was too much for my models as i would have to somehow reduce the faces wich would end pretty ugly, so i just tired to make my own which has a footprint of 5x4 verts.

The vulva (plural: vulvas or vulvae; derived from Latin for wrapper or covering) consists of the external female sex organs. The vulva includes the mons pubis (or mons veneris), labia majora, labia minora, clitoris, vestibular bulbs, vulval vestibule, urinary meatus, the vaginal opening, hymen, and Bartholin's and Skene's vestibular glands. The urinary meatus is also included as it opens into the vulval vestibule. Other features of the vulva include the pudendal cleft, sebaceous glands, the urogenital triangle (anterior part of the perineum), and pubic hair. The vulva includes the entrance to the vagina, which leads to the uterus, and provides a double layer of protection for this by the folds of the outer and inner labia. Pelvic floor muscles support the structures of the vulva. Other muscles of the urogenital triangle also give support.
Following the development of the vulva, changes take place at birth, childhood, puberty, menopause and post-menopause. There is a great deal of variation in the appearance of the vulva, particularly in relation to the labia minora. The vulva can be affected by many disorders which may often result in irritation. Vulvovaginal health measures can prevent many of these. Other disorders include a number of infections and cancers. There are several vulval restorative surgeries known as genitoplasties, and some of these are also used as cosmetic surgery procedures.
Different cultures have held different views of the vulva. Some ancient religions and societies have worshipped the vulva and revered the female as a goddess. Major traditions in Hinduism continue this. In Western societies, there has been a largely negative attitude typified by the medical terminology of pudenda membra, meaning parts to be ashamed of. There has been an artistic reaction to this in various attempts to bring about a more positive and natural outlook, such as work from British, American, and Japanese artists. While the vagina is a separate part of the anatomy, it has often been used synonymously with vulva.
The area between the labia minora where the vaginal opening and the urinary meatus are located is called the vulval vestibule, or vestibule of the vagina. The urinary meatus is below the clitoris and just in front of the vaginal opening which is near to the perineum. The term introitus is more technically correct than "opening", since the vagina is usually collapsed, with the opening closed. The introitus is sometimes partly covered by a membrane called the hymen. The hymen will usually rupture during the first episode of vigorous sex, and the blood produced by this rupture has been seen to signify virginity. However, the hymen may also rupture spontaneously during exercise or be stretched by normal activities such as the use of tampons and menstrual cups, or be so minor as to be unnoticeable, or be absent.[13] In some rare cases, the hymen may completely cover the vaginal opening, requiring a surgical procedure called a hymenotomy.[16] On either side of the back part of the vaginal opening are the two greater vestibular glands known as Bartholin's glands. These glands secrete mucus and a vaginal and vulval lubricant.[17] They are homologous to the bulbourethral glands in the male.[2] The lesser vestibular glands known as Skene's glands, are found on the anterior wall of the vagina. They are homologues of the male prostate gland and are also referred to as the female prostate.[18]
Pelvic floor muscles help to support the vulvar structures. The voluntary, pubococcygeus muscle, part of the levator ani muscle partially constricts the vaginal opening.[19] Other muscles of the urogenital triangle support the vulvar area and they include the transverse perineal muscles, the bulbospongiosus, and the ischiocavernosus muscles.[20] The bulbospongiosus muscle decreases the vaginal opening.[9] Their contractions play a role in the vaginal contractions of orgasm by causing the vestibular bulbs to contract.[21]
The ilioinguinal nerve originates from the first lumbar nerve and gives branches that include the anterior labial nerves which supply the skin of the mons pubis and the labia majora.[25] The perineal nerve is one of the terminal branches of the pudendal nerve and this branches into the posterior labial nerves to supply the labia.[25] The pudendal nerve branches include the dorsal nerve of clitoris which gives sensation to the clitoris.[25] The clitoral glans is seen to be populated by a large number of small nerves, a number that decreases as the tissue changes towards the urethra.[26] The density of nerves at the glans indicates that it is the center of heightened sensation.[26] Cavernous nerves from the uterovaginal plexus supply the erectile tissue of the clitoris.[27] These are joined underneath the pubic arch by the dorsal nerve of the clitoris.[28]The pudendal nerve enters the pelvis through the lesser sciatic foramen and continues medial to the internal pudendal artery. The point where the nerve circles the ischial spine is the location where a pudendal block of local anesthetic can be administered to inhibit sensation to the vulva.[29] A number of smaller nerves split off from the pudendal nerve. The deep branch of the perineal nerve supplies the muscles of the perineum and a branch of this supplies the bulb of the vestibule.[30][31]
There is a great deal of variation in the appearance of female genitals.[13] Much of this variation lies in the significant differences in the size, shape, and color of the labia minora. Though called the smaller lips they can often be of considerable size and may protrude outside the vagina or labia majora.[13][6] This variation has also been evidenced in a large display of 400 vulval casts called the Great Wall of Vagina created by Jamie McCartney to fill the lack of information of what a normal vulva looks like. The casts taken from a large and varied group of women showed clearly that there is much variation.[35] Pubic hair also varies in its color, texture, and amount of curl.[13]
In week three of the development of the embryo, mesenchyme cells from the primitive streak migrate around the cloacal membrane.[37] Early in the fifth week the cells form two swellings called the cloacal folds.[38] The cloacal folds meet in front of the cloacal membrane and form a raised area known as the genital tubercle.[38][37] The urorectal septum fuses with the cloacal membrane to form the perineum. This division creates two areas one surrounded by the urethral folds and the other by the anal folds.[38][37] These areas become the urogenital triangle and the anal triangle.[2] The area between the vagina and the anus is known as the clinical perineum.[2]
The uterovaginal canal or genital canal, forms in the third month of the development of the urogenital system. The lower part of the canal is blocked off by a plate of tissue, the vaginal plate. This tissue develops and lengthens during the third to fifth months and the lower part of the vaginal canal is formed by a process of desquamation or cell shedding. The end of the vaginal canal is blocked off by an endodermal membrane which separates the opening from the vestibule. In the fifth month the membrane degenerates but leaves a remnant called the hymen.[38]
In pregnancy the vulva and vagina take on a bluish colouring due to venous congestion. This appears between the eighth and twelfth week and continues to darken as the pregnancy continues.[2] Estrogen is produced in large quantities during pregnancy and this causes the external genitals to become enlarged. The vaginal opening and the vagina are also enlarged.[52] After childbirth a vaginal discharge known as lochia is produced and continues for about ten days.[52] 2ff7e9595c
