Fornix
Fornix In anatomy, a vaultlike or arched structure.
RELATED TERMS--------------------------------------
Anatomy
The study of form. Gross anatomy involves structures that can be seen with the naked eye. It is as opposed to microscopic anatomy (or histology) which involves structures seen under the microscope.
SIMILAR TERMS--------------------------------------
Fornication
Sexual intercourse that is "illicit", outside of marriage. The term "fornication" has a close medical relative by the name of "fornix", the word for "arch" in Latin. It seems that the Roman prostitutes used to hang out under the arches of certain public buildings. The act of carrying on an illicit relationship consequently came to be called "going under the arches" or fornication. Not to be confused with formication.
Fornices
Plural form of fornix.
Fornix cerebri
An arching fibrous band in the brain connecting the two lobes of the cerebrum. (The cerebrum is the largest part of the brain and consists of two hemispheres separated by a deep longitudinal fissure). Each fornix -- there are two -- in the brain is an arched tract of nerves.
Fornix conjunctivae
The fornix of the conjunctivae refers to loose arching folds connecting the conjunctival membrane lining the inside of the eyelid with the conjunctival membrane covering the eyeball.
Fornix uteri
The fornix of the uterus refers to the anterior (front) and posterior (back) recesses into which the upper vagina is divided. These vaultlike recesses are formed by protrusion of the cervix into the vagina. The fornix uteri is also known as the fornix vaginae (the vaginal fornix).
PREVIOUS AND NEXT TERMS--------------------------------------
Formula feeding
Feeding an infant or toddler prepared formula rather than breast-feeding, or in addition to breast-feeding. Formula feeding is indicated when the mother has an illness that could be passed on to the baby through breast milk or through the close physical proximity required for breast-feeding. Otherwise, experts in infant nutrition agree that breast-feeding is best.
Formula, infant
A substitute for breast milk for feeding infants. Pediatricians generally advise exclusively breastfeeding (that is, breastfeeding with no formula) for all full term, healthy infants for the first 6 months of life. However, many infants are formula-fed today, at least in part. For infants to achieve normal growth and maintain normal health, infant formulas must include proper amounts of water, carbohydrate, protein, fat, vitamins, and minerals.
Formulary
1. A collection of formulas, recipes, or prescriptions. 2. In medicine, a listing of prescription drugs approved for use.

Founder effect
The positive effect on gene frequency when a population (a colony) has only a small number of original settlers (founders) one or more of whom had that gene. For example, the gene for Huntington disease was introduced into the Lake Maracaibo region in Venezuela early in the 19th century. So there are now over a hundred persons with Huntington disease and at least 900 persons at risk for that deadly disease in that region, the largest known aggregation with the Huntington gene in the world.
Fourth cranial nerve
The fourth cranial nerve, the trochlear nerve, is the nerve supply to the superior oblique muscle of the eye, one of the muscles that moves the eye. Paralysis of the trochlear nerve results in rotation of the eyeball upward and outward (and, therefore, double vision).
