A neuromuscular junction (sometimes called a myoneural junction) is a junction between nerve and muscle; it is a chemical synapse formed by the contact between the presynaptic terminal of a motor neuron and the postsynaptic membrane of a muscle fiber.he binding of ACh to the receptor can depolarize the muscle fiber, causing a cascade that eventually results in muscle contraction. Neuromuscular junction diseases can be of genetic and autoimmune origin.
Definition of:Micro USB. The very small USB port found on cellphones and other portable devices is a Micro-B socket. Considerably smaller than the USB Type B sockets on printers and scanners, the Micro-B socket is half the thickness of the Mini-B socket found on digital cameras. Micro-A plugs and Micro-AB sockets are the standard connectors for USB On-The-Go (see USB OTG). See USB 3.0 and USB.
