Orgasmic Platform
The orgasmic platform is the tissues of the outer third of the vagina, labeled by Masters and Johnson. They swell considerably, and the pubococcygeus muscle The levator ani is a broad, thin muscle group, situated on either side of the pelvis. It is formed from three muscle components: the pubococcygeus, the iliococcygeus, and the puborectalis. It is attached to the inner surface of each side of the ... tightens, reducing the diameter of the opening of the vagina. During orgasm, women experience rhythmic contractions of the orgasmic platform. The orgasmic platform is brought about through the swelling of the bulbus vestibuli that narrows the vestibulum. It is actually the narrowing and the extending of the lower 1/3 of the sheath. References {{DEFAULTSORT:Orgasmic Platform Gynaecology Tissues (biology) ...

Tissue (biology)
In biology, tissue is a biological organizational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues. The English word "tissue" derives from the French word "tissu", the past participle of the verb tisser, "to weave". The study of tissues is known as histology or, in connection with disease, as histopathology. Xavier Bichat is considered as the "Father of Histology". Plant histology is studied in both plant anatomy and physiology. The classical tools for studying tissues are the paraffin block in which tissue is embedded and then sectioned, the histological stain, and the optical microscope. Developments in electron microscopy, immunofluorescence, and the use of frozen tissue-sections have enhanced the detail that can be observed in tissues. With these tools, the c ...

Vagina
In mammals, the vagina is the elastic, muscular part of the female genital tract. In humans, it extends from the vestibule to the cervix. The outer vaginal opening is normally partly covered by a thin layer of mucosal tissue called the hymen. At the deep end, the cervix (neck of the uterus) bulges into the vagina. The vagina allows for sexual intercourse and birth. It also channels menstrual flow, which occurs in humans and closely related primates as part of the menstrual cycle. Although research on the vagina is especially lacking for different animals, its location, structure and size are documented as varying among species. Female mammals usually have two external openings in the vulva; these are the urethral opening for the urinary tract and the vaginal opening for the genital tract. This is different from male mammals, who usually have a single urethral opening for both urination and reproduction. The vaginal opening is much larger than the nearby urethral opening, an ...

Masters And Johnson
The Masters and Johnson research team, composed of William H. Masters and Virginia E. Johnson, pioneered research into the nature of human sexual response and the diagnosis and treatment of sexual disorders and dysfunctions from 1957 until the 1990s. The work of Masters and Johnson began in the Department of Obstetrics and Gynecology at Washington University in St. Louis and was continued at the independent not-for-profit research institution they founded in St. Louis in 1964, originally called the Reproductive Biology Research Foundation and renamed the Masters and Johnson Institute in 1978. In the initial phase of Masters and Johnson's studies, from 1957 until 1965, they recorded some of the first laboratory data on the anatomy and physiology of human sexual response based on direct observation of 382 women and 312 men in what they conservatively estimated to be "10,000 complete cycles of sexual response". Their findings, particularly on the nature of female sexual arousal (fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pubococcygeus Muscle
The levator ani is a broad, thin muscle group, situated on either side of the pelvis. It is formed from three muscle components: the pubococcygeus, the iliococcygeus, and the puborectalis. It is attached to the inner surface of each side of the lesser pelvis, and these unite to form the greater part of the pelvic floor. The coccygeus muscle completes the pelvic floor, which is also called the ''pelvic diaphragm''. It supports the viscera in the pelvic cavity, and surrounds the various structures that pass through it. The levator ani is the main pelvic floor muscle and painfully contracts during vaginismus. It also contracts rhythmically during orgasm. Structure The levator ani is made up of 3 parts: * Iliococcygeus muscle * Pubococcygeus muscle * Puborectalis muscle The iliococcygeus arises from the inner side of the ischium (the lower and back part of the hip bone) and from the posterior part of the tendinous arch of the obturator fascia, and is attached to the coccyx and a ...

Gynaecology
Gynaecology or gynecology (see spelling differences) is the area of medicine that involves the treatment of women's diseases, especially those of the reproductive organs. It is often paired with the field of obstetrics, forming the combined area of obstetrics and gynecology (OB-GYN). The term comes from Greek and means "the science of women". Its counterpart is andrology, which deals with medical issues specific to the male reproductive system. Etymology The word "gynaecology" comes from the oblique stem (γυναικ-) of the Greek word γυνή (''gyne)'' semantically attached to "woman", and ''-logia'', with the semantic attachment "study". The word gynaecology in Kurdish means "jinekolojî", separated word as "jin-ekolojî", so the Kurdish "jin" called like "gyn" and means in Kurdish "woman". History Antiquity The Kahun Gynaecological Papyrus, dated to about 1800 BC, deals with gynaecological diseases, fertility, pregnancy, contraception, etc. The text is divided into th ...
