The act or process of joining or the condition of being joined. Gap junctions (also called communicating junctions) provide cytoplasmic channels from one cell to an adjacent cell. Mechanism of the Neuromuscular Transmission 3. In cell biology, focal adhesions (also cell–matrix adhesions or FAs) are large macromolecular assemblies through which mechanical force and regulatory signals are transmitted between the extracellular matrix (ECM) and an interacting cell. Abbreviation to define. Learning Outcomes. gap-junctions [engl., = Lückenverbindungen], Nexus, der metabolischen Kooperation (Zellkommunikation) und der Erregungsübertragung (Elektrokupplungen) zwischen den Zellen dienende Zellkontakte (), die in fast allen tierischen Geweben vorhanden sind und durch die Ionen und Moleküle bis zu einer bestimmten relativen Molekülmasse (ca. In this study, we have identified an important role of mammalian Lnp1 (mLnp1) in stabilizing nascent three-way ER junctions. A neuromuscular junction (NMJ), also called a myoneural junction, is the connection between a motor neurons and a muscle fibers. This expansion is known as the sole foot region or axon telodendria or terminal boutons. Definition.

RNA-seq) and to analyze the expression of these specific transcripts in larger sample sets (using RT-qPCR), we are now ready to further investigate the biological meaning of these specific transcripts. Meaning of Neuromuscular Junction: Neuromuscular junction (Fig. What is the definition of cell junction? Adherens junctions (or zonula adherens, intermediate junction, or "belt desmosome") are protein complexes that occur at cell–cell junctions in epithelial and endothelial tissues, usually more basal than tight junctions.An adherens junction is defined as a cell junction whose cytoplasmic face is linked to the actin cytoskeleton. 2.14) is a functional junction between a nerve fiber and a muscle fiber. Holliday junction, cross-shaped structure that forms during the process of genetic recombination, when two double-stranded DNA molecules become separated into four strands in order to exchange segments of genetic information.
