The neuromuscular junction (NMJ) is a chemical synapse that is anatomically and functionally differentiated for the transmission of a signal from the motor nerve terminal to a circumscribed postsynaptic region on the muscle fiber. Despite the differences, all NMJs have principal components such as (...
As a result of the inhibition of the hydrolysis of acetylcholine, acetylcholine accumulates in the neuromuscular junction. 由于水解减少,在神经肌肉接合部位的乙酰胆碱水平升高。 www.xqnmz.com 2. Damage to the neuromuscular junction following prolonged retraction can also lead to muscle denervation. 持续长...

As an overview of the structure of the neuromuscular junction, three items are described focusing on cooperative mechanisms involving the synapse and leading to muscle contraction: (1) presynaptic acetylcholine release regulated by vesicle cycling (exocytosis and endocytosis); the fast-mode of endocytosis...
Motor neuron axons join the skeletal muscle at the neuromuscular junction. Motor end plate is a specialized region of the sarcolemma at the neuromuscular junction. A motor unit consists of the motor neuron and the muscle fibers it controls. ...

For example, if neurotransmitters such as acetylcholine (ACh) and glutamate (Glu) released by a pre-synaptic signal stimulate ion channels which are permeable to Na+ at the neuromuscular junction, this action will depolarize the post-synaptic cell, causing the membrane potential to move toward the...
