Gap junction - Wikipedia
Gap junctions are membrane channels between adjacent cells that allow the direct exchange of cytoplasmic substances. [1] Substances exchanged include small molecules, substrates, and metabolites. [1]
Gap Junction: Definition, Function, Structure - Biology Dictionary
2019年10月4日 · Gap junctions are a type of cell junction in which adjacent cells are connected through protein channels. These channels connect the cytoplasm of each cell and allow molecules, ions, and electrical signals to pass between them.
5.3C: Gap Junctions - Medicine LibreTexts
2023年1月17日 · Gap junctions are also called communicating junctions, macula communicans, or nexuses. These are connections that allow for the direct passage of molecules between two cells. Gap junctions consist of a number of transmembrane channels called pores that are found in a closely packed arrangement.

2023年8月29日 · Gap junctions allow direct communication between neighboring cells. It allows them to exchange various substances, including ions, metabolites, and signaling molecules. This direct transfer of substances facilitates coordinated …
Cell - Gap Junctions, Intercellular Communication, Connexins
2024年12月8日 · These junctions allow communication between adjacent cells via the passage of small molecules directly from the cytoplasm of one cell to that of another. Molecules that can pass between cells coupled by gap junctions include inorganic salts, sugars, amino acids, nucleotides, and vitamins but not large molecules such as proteins or nucleic acids.

2022年12月30日 · Unlike the other types of cell-cell adhesion, the gap junction (sometimes called a nexus) connects not only the outside of two cells, it connects their cytoplasm as well. Each cell has a connexon (aka hemichannel) made of six connexin proteins.
Cell junctions: Types, Structure and Functions
2023年4月26日 · Gap junctions are intercellular channels that enable direct communication and the exchange of ions, tiny molecules, and electrical impulses between neighboring cells. Here are some crucial aspects to consider when learning about gap junctions:
3.15: Junctions between Cells - Biology LibreTexts
2022年5月15日 · Gap junctions are intercellular channels some 1.5–2 nm in diameter. These permit the free passage between the cells of ions and small molecules (up to a molecular weight of about 1000 daltons). They are cylinders constructed from 6 copies of transmembrane proteins called connexins.
Gap junction Definition and Examples - Biology Online
2021年1月19日 · A gap junction is a type of cell junction characterized by an intercellular bridge (i.e. ~2 nm gap) that forms between the membranes of neighboring cells. It is involved in intercellular communication, i.e. allowing the direct passage of ions, small molecules, or electrical impulses from one cell to another.
Gap Junctions - (Anatomy and Physiology I) - Fiveable
Gap junctions are specialized intercellular connections that allow for the direct transfer of ions, small molecules, and electrical signals between adjacent cells. These specialized membrane channels facilitate communication and synchronization between connected cells, playing crucial roles in various tissues and physiological processes.
