This substance is called as neurotransmitter. Here it is acetylcholine.
The intersection between a neuron and another neuron, a muscle, a gland, or a sensory receptor is called a synapse. At this junction, the transmitting neuron releases neurotransmitters that bind to receptors on the receiving cell, which can be another neuron, a muscle cell (causing contraction), a gland (triggering secretion), or a sensory receptor (initiating sensory processing). This communication is crucial for nervous system function, allowing for the integration of signals and responses throughout the body.
To "connect" two neurons, (or a neuron and a muscle cell), by providing a space between an axon terminal of one neuron and a dendrite of another neuron (or a muscle cell), so neurotransmitters that are released by an axon terminal can diffuse across that space to reach the dendrite (or muscle cell) and either initiate the possibility of the second neuron to fire or cause a muscle cell to contract.

There is a space (synapsis) between the neuron and the muscle cell. The electrical impulse can not pass over that. Chemical neurotransmitters are manufactured by neurons in the soma, then stored in little bundles called synaptic vesicles and transferred to the synapses. The release of the neurotransmitter is required for a nerve to simulate the muscle. This is what crosses the space.
The synapse, or connection, between a neuron and striated muscle is typically a chemical one called the neuromuscular junction. The pre-synaptic terminus coming from the neuron releases acetylcholine (ACh) which triggers an opening of the ionic channels on the muscle side. The depolarization triggers calcium entry into the cytosol of the muscle and contraction.

synaptic cleft
A motor unit consists of a motor neuron and the muscle fibers it controls. The motor neuron sends signals to the muscle fibers to contract, while the motor unit refers to the combination of the neuron and the muscle fibers it innervates.
Neuromuscular junction. It is the point of contact between the motor neuron and the skeletal muscle cell, where the motor neuron releases neurotransmitters that trigger muscle contraction.
via chemicals called neurotransmitters, expressed at sites called synapses, which are tiny gaps between a neuron and another neuron or a muscle cell.
The neuron releases its neurotransmitter into the synaptic cleft at the neuromuscular junction, which is the gap between the neuron terminal and the muscle cell. This neurotransmitter then binds to receptors on the muscle cell membrane, triggering muscle contraction.

A Motor neuron is a neuron that carries impulses from the spinal cord to muscle cells.A Motor neuron is a neuron that carries impulses from the spinal cord to muscle cells.
The location where a neuron transfers an impulse to another neuron or to a muscle cell is called a synapse. At the synapse, the presynaptic neuron releases neurotransmitters that bind to receptors on the postsynaptic neuron or muscle cell, facilitating the transmission of the signal. This process is crucial for communication within the nervous system and between nerves and muscles.
