fornic-, fornix-

(Latin: arch; vault)

Referring to, pertaining to, or belonging to a fornix.
fornical commissure, commissura fornicis
The transverse part of the fornix, uniting the crura or the legs; especially, from the knees to the feet.

Crura is the plural form of crus and refers to any anatomical structure resembling a leg; usually (in the plural) a pair of diverging bands or elongated masses.

1. Arched or vaulted.
2. Shaped like a fornix.
fornicolumn, columna fornicis, column of fornix
1. A column or pillar of the fornix.
2. That part of the fornix that curves down in front of the thalamus and the interventricular foramen (slit-like passage ) of Monro, then continues through the hypothalamus to the mamillary body; consisting primarily of fibers originating in the hippocampus and subiculum (support or prop), the column of fornix is the direct continuation of the body of the fornix.
fornix (s), fornices (pl)
1. Any arch-like structure or the concave recess produced by such a structure.
2. An archlike anatomical structure or fold, such as the arched band of white matter located beneath the corpus callosum of the brain.
  • The fornix in the brain is a fibrous arching band connecting the two lobes of the cerebrum.
  • The fornix of the conjunctivae or loose arching folds connecting the conjunctival membrane lining the inside of the eyelid with the conjunctival membrane covering the eyeball.
  • The fornix of the vagina is the anterior (front) and posterior (back) recesses into which the upper vagina is divided.
  • Fornix is the Latin word for "vault or arch".
fornix cerebri
An arching fibrous band in the brain connecting the two lobes of the cerebrum which is the biggest part of the brain and consists of two hemispheres separated by a deep longitudinal fissure.

Each of the two fornices or vault-like or arched structures in the brain is an arched tract of nerves.

fornix conjunctivae
The loose arching folds connecting the conjunctival membrane lining the inside of the eyelid with the conjunctival membrane covering the eyeball.
fornix of the stomach, fundus ventriculi
The portion of the stomach that lies above the cardiac notch or the area between the oesophagus and fundus (bottom or base) of the stomach.
fornix pharyngis, fornix of pharynx, vault of pharynx
The extreme upper part of the pharynx (the passage to the stomach and lungs; in the front part of the neck below the chin and above the collarbone).
fornix saccilacrimalis, fornix sacci lacrimalis, fornix of lacrimal sac
1. The extreme upper part of the lacrimal sac or either of the two dilated ends of the lacrimal ducts at the nasal ends of the eyes that fill with tears that are secreted by the lacrimal glands.
2. The dome-shaped upper junction of the lateral and medial walls of the lacrimal (tear) sac which is situated above the level of the opening of the lacrimal canaliculi or lacrimal canals.

Lacrimal canals are curved, tube shaped structures connected to the lacrimal puncta, that tears coming from the lacrimal lake drain into.

The lacrimal puncta are tiny openings towards the inner part of each eyelid, which the tears drain through.

The lacrimal lake is a small open area in each of the eyes where tears collect.

The superior (top) lacrimal canal is on the top and the inferior (lower) lacrimal canal is on the bottom and both lacrimal canals are located in the border of the each eyelid, near the area where the top and bottom eyelids come together.

Tears travel across the middle from the lacrimal canals to the lacrimal sacs and the lacrimal sacs are hollow spaces into which the lacrimal canals drain tears.
