Human: What are the five major types of synapse? Assistant: 

1. Chemical Synapse  - This type of synapse is formed by the release of neurotransmitters from one neuron that binds to receptors on another neuron, resulting in an electrical signal being sent across the synapse.
2. Electrical Synapse - This type of synapse occurs when a neuron sends an electrical signal to another neuron through gap junctions. The two neurons form an electrical connection and transmit signals between each other.
3. Neuromuscular Junction (NMJ) - This type of synapse is found at the neuromuscular junction, which connects motor neurons to skeletal muscles. When a nerve impulse reaches the muscle, it causes the release of acetylcholine, which binds to receptors on the muscle fiber, triggering contraction.
4. Dendritic Synapse - This type of synapse involves chemical communication between dendrites and cell bodies. Signals travel down the axon of a neuron and then back up the dendrite, where they can be received by the cell body.
5. Glial Synapse - This type of synapse is formed by glial cells and is used for transmitting information within the central nervous system.
