Chemically Gated Channels.
chemically gated channels
1. Nerve impulse reaches synaptic terminal. 2. Synaptic vesicles move to and merge with the presynaptic cell membrane of the motor neuron. 3. Acetylcholine is released into and diffuses across the synaptic cleft. 4. Acetylcholine binds to receptors on the postsynaptic cell membrane of the muscle fiber.
Protein molecules on the post-synaptic cell membrane form receptor sites that bind with neurotransmitters released from the pre-synaptic neuron. This binding triggers downstream signaling pathways within the post-synaptic cell, leading to various cellular responses.

Nerve impulses are transmitted down the axon and leave the neuron via the terminal bouton at the synaptic interface, releasing neurotransmitters into the synaptic cleft to affect the post-synaptic cell..
An example of a presynaptic cell is a neuron that releases neurotransmitters into the synaptic cleft to communicate with the postsynaptic cell.

Synaptic adhesion molecules span the synaptic cleft, holding the axon terminal to the dendrite. There are a number of different kinds of synaptic adhesion molecules, which typically have a portion that starts slightly inside an axon terminal and protrudes outside more than halfway into the synaptic cleft, meeting and over-lapping and sticking against a companion sam protruding similarly from a dendrite, thus maintaining the relative position of the axon terminal and dendrite.
