junction

[′jəŋk·shən]
(civil engineering)
A point of intersection of roads or highways, especially where one terminates.
(electricity)
(electronics)
A region of transition between two different semiconducting regions in a semiconductor device, such as a pn junction, or between a metal and a semiconductor.
(electromagnetism)
A fitting used to join a branch waveguide at an angle to a main waveguide, as in a tee junction. Also known as waveguide junction.

junction

The point at which two elements make contact. In a transistor, a junction is the point where an N-type material makes contact with a P-type material.

The squamocolumnar junction (Z line) and the GEJ may not be the same in a given specimen.
Several studies have shown that colposcopically directed biopsy of even normal-appearing areas at the squamocolumnar junction or within large ectopies can improve detection of high-grade cervical intraepithelial neoplasia or adenocarcinoma in situ.
Less often, an enlarged gastric fold near the squamocolumnar junction, also called the sentinel fold, is seen in reflux esophagitis.
Women treated by ELECTZ conization were older (32.2 vs 25.1 years, P=.02), were more likely to develop posttreatment cervical stenosis (25.9% vs 3.8%, P=.001), and were more likely to have the postoperative squamocolumnar junction positioned in the endocervical canal (32.4% vs 8.7%, P=.002) than were women treated by ELECTZ.
The point at which they meet is known as squamocolumnar junction. In neonates the squamocolumnar junction is located on the exocervix.
The opposing view holds that squamous dysplasia arises at the squamocolumnar junction and does not "skip" over apparently normal endocervical tissue to restart de novo within the canal.
A 19-mm flat cryoprobe tip is commonly advocated for cervical cryosurgery.[14] The rationale for use of this cryoprobe is based on the theories that the flat probe, when compared with the cone-shaped probe tip, will not reposition the squamocolumnar junction within the endocervical canal following cryosurgery and that cervical stenosis will be minimized.
