• Within a gap junction reside protein complexes, referred initially to as "globules", observed to connect one cell to another and also vesicles within a cell to the outer cell membrane. (wikipedia.org)
  • Vesicles formed when cell-membrane coated pits (COATED PITS, CELL-MEMBRANE) invaginate and pinch off. (lookformedical.com)
  • Specialized regions of the cell membrane composed of pits coated with a bristle covering made of the protein CLATHRIN. (lookformedical.com)
  • An adaptor protein complex primarily involved in the formation of clathrin-related endocytotic vesicles (ENDOSOMES) at the CELL MEMBRANE. (lookformedical.com)
  • They perform functions such as binding to the cell membrane, capturing cargo molecules and promoting the assembly of CLATHRIN. (lookformedical.com)
  • A network of membrane compartments, located at the cytoplasmic side of the GOLGI APPARATUS, where proteins and lipids are sorted for transport to various locations in the cell or cell membrane. (lookformedical.com)
  • A similar section of a gram-negative cell enve- lope shows a complete sandwich with three layers: the cell wall, composed of an outer membrane and a thin layer of peptidoglycan, and the cell membrane. (forex-consultant.com)
  • The middle ear consists of the tympanic cavity, an air-filled cavity whose outer walls form the tympanic membrane (eardrum), and communicates proximally with the nasopharynx by the Eustachian tubes, which maintain pressure equilibrium on either side of the tympanic membrane. (cloudaccess.net)
  • They play a role in the intracellular transport of molecules contained within membrane vesicles. (lookformedical.com)
  • The more recently characterized pannexin family, which was originally thought to form inter-cellular channels (with an amino acid sequence similar to innexins), in fact functions as a single-membrane channel that communicates with the extracellular environment, and has been shown to pass calcium and ATP. (wikipedia.org)
  • Cellular uptake of extracellular materials within membrane-limited vacuoles or microvesicles. (lookformedical.com)
  • Ephapses are often studied in the context of electrically induced potentials propagated among groups of nerve cell membranes, even in the absence of gap junction communication, with no discrete subcellular structures known. (wikipedia.org)
  • The bodies of the cochlear sensory cells resting on the basilar membrane are surrounded by nerve terminals, and their approximately 30,000 axons form the cochlear nerve. (cloudaccess.net)
  • Traversing an extraordinarily thin membrane, the cilia of the hair cells are embedded in the tectorial membrane, whose free end is located above the cells. (cloudaccess.net)
  • While more than 26 different connexins frequently populate gap junctions in various different tissues there are at least 12 other components that form the specialized area of membrane called the gap junction. (wikipedia.org)
  • The basilar membrane forms the inferior surface of the cochlear canal, and supports the organ of Corti, responsible for the transduction of acoustic stimuli. (cloudaccess.net)
  • The superior surface of the cochlear canal is formed by Reissner's membrane. (cloudaccess.net)
