El \u00fatero    <\/h1>\n

El \u00fatero es un \u00f3rgano en forma de pera localizado entre la vejiga y el recto. En la mujer no embarazada mide alrededor de 3 pulgadas (7cm) de longitud y est\u00e1 normalmente en la posici\u00f3n de anteroversi\u00f3n. La porci\u00f3n superior del \u00fatero es el fundus y la porci\u00f3n central mas larga es conocida como el cuerpo uterino o corpus uteri. La porci\u00f3n inferior mas angosta es el cervix uteri (que significa cuello del \u00fatero) y a su vez abre en la vagina. El fundus y el cuerpo uterino tienen gruesas paredes musculares (el miometrio) que se hacen m\u00e1s gruesas durante el embarazo y una mucosa especializada (el endometrio) que es capaz de sostener el feto en desarrollo.<\/p>\n

El recubrimiento endometrial de la cavidad uterina es un epitelio cil\u00edndrico ciliado y es sostenido por un tejido conectivo celular que contiene numerosas gl\u00e1ndulas tubulares. Bajo la influencia de los estr\u00f3genos y progestagenos secretados por los fol\u00edculos ov\u00e1ricos, el endometrio pasa por cambios c\u00edclicos regulares que preparan el \u00fatero para la recepci\u00f3n del \u00f3vulo fecundado. La implantaci\u00f3n exitosa solo puede ocurrir si el endometrio provee al embri\u00f3n temprano con abundantes nutrientes.<\/p>\n

Los cambios c\u00edclicos en el endometrio pasan por dos distintas fases: proliferativa y secretora.<\/p>\n

Uterine cycle; menstrual, proliferative and secretory phases. D. Ovarian hormone cycle’ oestrogen and progesterone levels. (Ross and Wilson: Anatomy and Physiology in health and illness; figure 19.10)<\/figcaption><\/figure>\n

 <\/p>\n

La fase proliferativa<\/h2>\n

Esta fase es iniciada y sostenida hasta la ovulaci\u00f3n por la producci\u00f3n gradual de estr\u00f3genos por los fol\u00edculos ov\u00e1ricos en desarrollo. Es caracterizada por la proliferaci\u00f3n del tejido conectivo endometrial que se hace m\u00e1s grueso y vascularizado. Las gl\u00e1ndulas simples tubulares proliferan y forman numerosas gl\u00e1ndulas que comienzan a secretar moco.<\/p>\n

La fase secretora<\/h2>\n

Es caracterizada por el aumento de la tortuosidad de las gl\u00e1ndulas bajo la influencia de la progesterona secretada por el cuerpo l\u00fateo. Las gl\u00e1ndulas producen abundantes secreciones ricas en gluc\u00f3geno, que es una importante fuente de nutrientes para el \u00f3vulo fecundado.<\/p>\n

 <\/p>\n

\"\"<\/a>
Endometrium in the early secretory phase. Note sub nuclear vacuoles and the slight tortuosity of the gland.<\/figcaption><\/figure>\n
\"\"<\/a>
Mid secretory phase of the cycle the sub nuclear vacuoles move to the super nuclear position and secrete their contents into the glands which become increasingly dilated and tortuous. Note oedatous stroma due to increased blood flow.<\/figcaption><\/figure>\n
\"\"<\/a>
Late secretory endometrium. The stroma consists largely of sheets of pre decidual cells infiltrated by polymorphs and lymphocytes. These increase in number as the endometrium undergoes menstrual changes characterised by necrosis glandular collapse and haemorrhage.<\/figcaption><\/figure>\n

 <\/p>\n

Menstruaci\u00f3n<\/h2>\n

Sin la implantaci\u00f3n de un \u00f3vulo fecundado el cuerpo l\u00fateo se degenera y la secreci\u00f3n de estr\u00f3genos y progesterona cesa. La constricci\u00f3n de las arterias espirales del endometrio resulta en isquemia y colapso de las gl\u00e1ndulas endometriales y el inicio de la menstruaci\u00f3n. Para el tercer o cuarto d\u00eda de menstruaci\u00f3n la mayor parte del recubrimiento endometrial ha sido expulsado y la proliferaci\u00f3n de las capas basales del endometrio inicia otra vez.<\/p>\n

El \u00fatero en embarazo<\/h2>\n

Cuando el \u00f3vulo es expulsado del ovario durante la ovulaci\u00f3n, es lanzado hacia la fimbria de la trompa de Falopio. La fecundaci\u00f3n usualmente tiene lugar en este sitio y el ovulo fecundado es llevado a lo largo de la trompa hasta la cavidad endometrial. Aproximadamente el 7\u00ba d\u00eda despu\u00e9s de la fecundaci\u00f3n el \u00f3vulo intenta implantarse en la pared uterina. Si la implantaci\u00f3n es exitosa el cuerpo l\u00fateo crece y contin\u00faa secretando estr\u00f3genos y progesterona de tal forma que el endometrio abundante en gluc\u00f3geno no involuciona. Aproximadamente el d\u00eda 12 la implantaci\u00f3n se completa. Bajo la influencia de la progesterona las c\u00e9lulas estromales del endometrio sufren cambio decidual y finalmente dominan el endometrio.<\/p>\n

Las c\u00e9lulas estromales son grandes con prominentes n\u00facleos redondeados con tinci\u00f3n p\u00e1lida y abundante citoplasma. Por \u00faltimo la decidua basal (que es la capa decidual inmediatamente debajo del sitio de implantaci\u00f3n), las vellosidades cori\u00f3nicas del feto y los espacios intervellosos se fusionan para formar la placenta.<\/p>\n

El \u00fatero en la postmenopausia<\/span><\/p>\n

Despu\u00e9s de la menopausia la producci\u00f3n c\u00edclica de estr\u00f3geno y progesterona por parte de los ovarios cesa y todo el tracto genital sufre cambios atr\u00f3ficos. El endometrio se hace delgado y consiste en escaso tejido conectivo y algunas gl\u00e1ndulas inactivas.
\n        <\/p>\n

El cuello uterino<\/h1>\n

(Para una descripci\u00f3n m\u00e1s detallada de la anatom\u00eda, fisiolog\u00eda e histolog\u00eda del cuello uterino por favor ver la siguiente secci\u00f3n)<\/p>\n

The cervix is the narrow inferior segment of the uterus which projects into the vaginal vault.  It is a fibromuscular organ lined by mucous membrane and measures 3 cm in length and 2.5cm in diameter. In the adult female, it is angled downwards and backwards. In the nulliparous female it is barrel shaped but it changes shape in pregnancy and the menopause. The cervix is continuous above with the body of the uterus and is continuous below with the vagina .About half the length of the cervix (the portio vaginalis) extends into the vagina. This portion is covered with stratified squamous epithelium which is continuous with the vaginal squamous epithelium. The cervix is traversed by the endocervical canal which is lined by glandular epithelium.<\/p>\n","protected":false},"excerpt":{"rendered":"
