Uterine junctional zone: function and disease
The Lancet, 1995The myometrium is usually thought of as a homogeneous mass of smooth muscle fibres. However, magnetic resonance studies of the uterus have revealed two distinct zones--the subendometrial myometrium or junctional zone and the outer myometrium. The junctional zone is not only structurally but also functionally different from the outer myometrium.

The junctional zone beneath migrating epidermis*
British Journal of Dermatology, 1975The changes that take palce in skin explants in vitro at the interface between migrating epidermal cells and dermis have been examined by light and electron microscopy and by immunofluorescent antibody techniques. In the first 24 hr epidermal cell migration occurred in the absence of any of the usual components of this junctional zone.

Uterine Junctional Zone and Endometrial Cancer
Geburtshilfe und Frauenheilkunde, 2009PURPOSE: The human uterus consists of the ontogenetically and phylogenetically older endometrium, the adjacent junctional zone and the more recent outer myometrium. This understanding of uterine zonal anatomy could provide an answer to the question why the risk of lymph node metastasis increases abruptly when an endometrial adenocarcinoma invades more ...

Separation Zone at Open‐Channel Junctions
Journal of Hydraulic Engineering, 1984The configuration of open-channel junctions controls local sedimentary processes, channel scour, and sidewall erosion through its influence on the flow patterns established as confluent streams compete for limited channel capacity. Entry of a tributary into a mainstream ensures detachment of flow from the channel sidewall immediately downstream from ...

Special Anatomical Zone: Craniocervical Junction Tumors
2020Tumors of the craniovertebral junction tumors (CVJ) remain a significant challenge, given the anatomic complexity of the region. A thorough clinical examination, interpretation of radiographic imaging, understanding of the regional anatomy, obtaining histologic diagnosis, and establishing the goals of surgery are necessary to provide the best outcomes.

The Rectosigmoid Junction Zone: Another Sphincter?
1981The junctional areas between the different parts of the gastrointestinal tract are usually defined by valves or sphincters. This rule is almost universal, in so far as there is the cardiac sphincter between the oesophagus and the stomach, the pyloric sphincter between the stomach and the duodenum, and the ileocaecal ‘valve’ between the terminal portion

Shear zone junctions: Of zippers and freeways
Journal of Structural Geology, 2017Abstract Ductile shear zones are commonly treated as straight high-strain domains with uniform shear sense and characteristic curved foliation trails, bounded by non-deforming wall rock. Many shear zones, however, are branched, and if movement on such branches is contemporaneous, the resulting shape can be complicated and lead to unusual shear sense ...

Controlled failure mechanisms toughen the dentino-enamel junction zone
The Journal of Prosthetic Dentistry, 2005The dentino-enamel junction (DEJ) durably unites dissimilar hard brittle enamel and tough flexible dentin. In contrast to artificial bonds between restorations and dentin, the DEJ rarely fails except when it is affected by inherited disorders. Knowledge of DEJ toughening mechanisms is important in understanding inherited disorders, in biomimetic ...

Active zone structure‐function relationships at the neuromuscular junction
Synapse, 2018AbstractThe impact of presynaptic transmitter release site organization on synaptic function has been a vibrant area of research for synaptic physiologists. Because there is a highly nonlinear relationship between presynaptic calcium influx and subsequent neurotransmitter release at synapses, the organization and density of calcium sources (voltage ...
