The cervix projects into the anterior part of the vault of the vagina so that the continuous gutter surrounding the cervix is shallow anteriorly (where the vaginal wall is 3in (7 actos 30 mg low price. This continuous gutter is, for convenience of description, divided into the anterior, posterior and lateralfornices. Relations •Anteriorly — the base of the bladder and the urethra (which is em- bedded in the anterior vaginal wall). The amateur abortionist (or inexperienced gynaecologist) without a knowledge of anatomy fails to realize that the uterus passes upwards and forwards from the vagina; he pushes the instrument or IUCD (intra-uterine contraceptive device), which he intends to enter the cervix, directly back- wards through the posterior fornix. To make matters worse, this is the only part of the vagina which is intraperitoneal; the peritoneal cavity is thus entered and peritonitis follows. Blood supply Arterial supply is from the internal iliac artery via its vaginal, uterine, inter- nal pudendal and middle rectal branches. Structure Astratified squamous epithelium lines the vagina and the vaginal cervix; it contains no glands and is lubricated partly by cervical mucus and partly by desquamated vaginal epithelial cells. In nulliparous women the vaginal wall is rugose, but it becomes smoother after childbirth. The rugae of the The female genital organs The uterus 143 The ovary has no peritoneal covering; the serosa ends at the mesovarian attachment. It consists of a connective tissue stroma containing at various stages of development, and (hyalinized, regressing corpora lutea, which take several months to absorb completely). It is now known, however, that the primordial follicles develop in the ovary in early fetal life and do not differentiate from these cells. In adult life, in fact, the epithelial covering of the ovary disappears, leaving only a fibrous capsule termed the. After the menopause the ovary becomes small and shrivelled; in old age the follicles disappear completely. The is the extraperitoneal cellular tissue of the uterus (the ), vagina, bladder and rectum. Within this endopelvic fascia are three important condensations of connective tissue which sling the pelvic viscera from the pelvic walls. A subcutaneous bursa is constantly present over the olecranon and is likely to become inflamed when exposed to repeated trauma.

The third potential complication is Volvulus—A twisted loop of bowel generic 45mg actos visa, causing obstruction due to intussusception, or a twist around a obstruction. This prob- lem presents as a small bowel obstruction, however, the true cause is identified at the time of surgical exploration. If there is obstruction, the abdomen will distend and there will be cramping pain and vomiting.

For the rat to make decisions based upon ongoing neural activity actos 15mg on-line, averaging responses across trials for a set of stimuli, is not a realistic processing strategy. The stimuli used in the dataset were single whisker deflections (the stimulus set was comprised of nine whiskers), and we determined in what way the resulting spike train on each trial reported the identity of the deflected whisker. The design of the experiment and the analysis can be thought of as a simplified physiological analogue of gap crossing. During the behav- ioral task the rat must continuously evaluate whether its barrel cortex activity has reported contact of the spared whisker with the opposite platform. One of the preferred strategies for determining the precise meaning of neuronal activity – for quantifying what neurons report about sensory events – is to employ the Mutual Information Theory of Shannon,14 or one of its several variants and derivatives. Information analyses measure how well an ideal observer of neuronal responses can discriminate between the stimuli that evoked them. For a given set of stimuli, the information transmitted about the stimuli increases when the neural response to each stimulus, on a typical trial, is increasingly unique. Informative responses carry more bits of information permitting the observer to greatly narrow down the estimate of which stimulus occurred. For the collection of physiological data, spike trains of small sets of single-units in barrel cortex were simultaneously recorded while whiskers were stimulated one at a time. On these same trials, the spike counts (where the entire 40-msec response period is considered as one bin) would be <2> and <1>. Taking the timing of spikes into consideration makes the cortical population code potentially very rich and complex. The application of a stimulus in fact activates many cortical neurons, each of which could emit several spikes.
