(Latin: between; among, mutually, together; on the inside, internal)
Although abstracted from the many compounds in which it entered English, the form inter- was not generally considered a living prefix in English until the 1400s.
During the later period of Middle English many words borrowed in the Old and Middle French forms entre-, enter- began to be consciously respelled with Latin inter-; although vestiges of the older French borrowings are found in entertain and enterprise.
The living prefix inter- is now freely added to almost any element in English to create such formations with the meaning of "between" and "among". The words formed by intra- are closely related to this inter- prefix; in fact, they both apparently came from the same Latin source.

- Lateral ventricles: The lateral ventricles are in the cerebral hemispheres. Each lateral ventricle consists of a triangular central body and four horns.
The lateral ventricles communicate with the third ventricle through the interventricular foramen (opening).
- The third ventricle is a median (midline) cavity in the brain that is bounded by the thalamus and hypothalamus on either side.
Anteriorly (in front) the third ventricle communicates with the lateral ventricles and posteriorly (in back) the third ventricle communicates with what is called the aqueduct of the midbrain (or the aqueduct of Sylvius).
- The fourth ventricle is the most inferior (lowest) of the four ventricles of the brain.
It extends from the aqueduct of the midbrain to the central canal of the upper end of the spinal cord with which it communicates by the two foramina (openings) of Luschka and the foramen (opening) of Magendie.
The ventricles are filled with cerebrospinal fluid, which is formed by structures called choroid plexuses located in the walls and roofs of the ventricles.
"The intervertebral discs or nucleus pulposus (soft moist solid) are fibro-cartilaginous discs that lie between the vertebral bodies in the spine."
These intervertebral disks are composed of a central gelatinous-like material that provide a cushioning or shock absorbing quality to the spinal column to axial stress. The discs may herniate or rupture, resulting in a condition known as a radiculopathy."
