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.
In the Catalog for USB-232/485 Series Interfaces, it says that the 1-port interface has a USB Type A plug whereas the 2- and 4-port interfaces have a USB Type B connector. What is the difference? Do I need any additional hardware to connect either one to my computer? Solution: The USB receptacle on your PC is a type A connector and can be recognized by its rectangular shape.Type A receptacles can be found on upstream devices such as a USB host, or a hub. Type A plugs can be found on cables, and smaller peripherals such as a mouse and a flash drive. However, many larger USB peripherals such as printers and scanners use a detachable cable, and use the Type B receptacle, which has a square shape. Instruments are another type of downstream device. To connect an instrument to your PC, you will need to use a USB Type A to Type B cable. The two types of plugs have the same number of pins, and are electrically identical. They are only different mechanically.
