Neuromuscular junction
Neuromuscular junction
A neuromuscular junction (or myoneural junction) is a chemical synapse formed by the contact between a motor neuron and a muscle fiber. It is at theneuromuscular junction that a motor neuron is able to transmit a signal to the muscle fiber, causing muscle contraction
Function
The neuromuscular junction (NMJ) is the site of communication between motor nerve axons and muscle fibres. ... The function of the NMJ is to transmit signals from the motor neuron to the skeletal muscle fibre quickly and reliably, to ensure precise control of skeletal muscle contraction and therefore voluntary movement.

Neuromuscular Junction Actions:
- Release of ACh. When a nerve pulse reaches a synaptic end bulb, it triggers release of the neurotransmitter acetylcholine (ACh) from synaptic vesicles that contain acetylcholine (ACh). ...
- Activation of ACh receptors. ...
- Generation of muscle action potential. ...
- Breakdown of ACh.
