The primary nervous junction

Webb8.2 The neuromuscular junction is comprised of three cell types The NMJ consists of the nerve ending from an alpha-motor neuron, a muscle fiber, and several nonmyelinating terminal/perisynaptic Schwann cells (T/PSCs) (Couteaux, 1947; Sanes and Lichtman, 1999; Darabid et al., 2014). WebbThe neuromuscular junction is the site of the signal exchange. The steps of this process in vertebrates occur as follows: (1) The action potential reaches the axon terminal. (2) Voltage-dependent calcium gates open, allowing calcium to enter the axon terminal.
