neurotransmitters
Synaptic Cleft.
synaptic cleft, where neurotransmitters are released by the synaptic terminal and bind to receptors on the muscle fiber to trigger a muscle contraction.
The small space separating pre and post-synaptic neurons is called the synaptic cleft. This cleft allows for the transmission of chemical signals, known as neurotransmitters, from the pre-synaptic neuron to the post-synaptic neuron to occur. The neurotransmitters are released by the pre-synaptic neuron and bind to receptors on the post-synaptic neuron to transmit the signal.

synaptic cleft
Neurotransmitters are the substances released into the synaptic cleft. They are chemical messengers that transmit signals across the synapse from one neuron to another.
c) neuromuscular junction, d) synaptic cleft.
The transport mechanism for a neurotransmitter across the synaptic cleft is called exocytosis. During exocytosis, neurotransmitter-filled vesicles fuse with the presynaptic membrane, releasing the neurotransmitter into the synaptic cleft where it can then bind to receptors on the postsynaptic membrane.
The gap between the axon terminal and muscle cell is called the synaptic cleft. It is defined as the small gap, measured in nanometers, between an axon terminal and any of the cell membranes in the immediate vicinity.

The gap between a neuron and its effector is called a synaptic cleft. Neurotransmitters are released from the neuron into this gap and then bind to receptors on the effector cell to transmit the signal.
Neurotransmitters are released from the nerve terminals by a specialized exocytosis process, synaptic vesicles. These are small nearly uniform capsules that join with the cell membrane to expel their contents. Release is both quantal (set amount) and mediated by calcium.
