During sexual intercourse in the missionary position, the tip of the penis may reach the anterior fornix, while in the rear-entry position it may reach the posterior fornix. [1] The anterior fornix is also called the a-spot, an analogue to the g-spot (Gräfenberg spot), which is closer to the vaginal opening, and also on the anterior side of ...
In women, the rectouterine pouch is the deepest point of the peritoneal cavity. It is posterior to the uterus, and anterior to the rectum. [2] Its anterior boundary is formed by the posterior fornix of the vagina. [1] The pouch on the other side of the uterus near to the anterior fornix is the vesicouterine pouch.
The posterior fibers (called the postcommissural fornix) of each side continue through the hypothalamus to the mammillary bodies; then to the anterior nuclei of thalamus via the mammillothalamic tract. The anterior fibers (precommissural fornix) end at the septal nuclei of the basal forebrain and nucleus accumbens of each half of the brain.
Where the vaginal lumen surrounds the cervix of the uterus, it is divided into four continuous regions (vaginal fornices); these are the anterior, posterior, right lateral, and left lateral fornices. [9] [10] The posterior fornix is deeper than the anterior fornix. [10] Supporting the vagina are its upper, middle, and lower third muscles and ...
The majority of the discharge pools in the deepest portion of the vagina (the posterior fornix) [3] and exits the body over the course of a day with the force of gravity. [1] [4] A typical reproductive-age woman produces 1.5 grams (half to one teaspoon) of vaginal discharge every day. [1]
A commissure (/ ˈ k ɒ m ə ʃ ər /) is the location at which two objects abut or are joined. The term is used especially in the fields of anatomy and biology. The most common usage of the term refers to the brain's commissures, of which there are at least nine. Such a commissure is a bundle of commissural fibers as a tract that crosses the midline at i
They are located at the ends of the anterior arches of the fornix. [3] They consist of two groups of nuclei, the medial mammillary nuclei and the lateral mammillary nuclei. [4] Neuroanatomists have often categorized the mammillary bodies as part of the posterior part of hypothalamus. [5]
Fusion of the septal laminae is attributed to rapid development of the alvei of the hippocampus, amygdala, septal nuclei, fornix, corpus callosum and other midline structures. Lack of such limbic development interrupts this posterior-to-anterior fusion, resulting in the continuation of the CSP into adulthood. [10]
