How do synapses grow

The synapses present in the brain might be axoaxonic, axosomatic, or axodendritic.The dendrites of the postsynaptic motor neurons also grow and remodel to accommodate the additional sensory input (bailey and chen 1988b).Synapse formation is a multistep process, during which a neuronal growth cone comes in contact with an appropriate target postsynaptic neuron, makes the decision to stop growing, and forms a presynaptic site.It's the ultimate question for scientists who study learning.Synapses form critical connections between neurons, allowing neurons to send signals and information throughout the body.

Astrocyte cells play a role in synapse development by giving neurons directions, such as telling them when to start growing a synapse, when to stop, when to prune it back, and when to stabilize the connection.They project onto muscles to allow muscle contraction, as well as enable a multitude of other functions that the nervous system covers.Basically, the axon of one neuron activates a second neuron and like a chain reaction, makes a synapse with one of its dendrites or within the cell body.The synapse is the functional unit of the brain.
