inal answer:
Cell-to-cell communication in the nervous system involves neurons transmitting signals through synapses using neurotransmitters. Glial cells support neuron function and play a role in modulating communication. Proper functioning of synaptic transmission is essential for all nervous system activities.
Step-by-step explanation:
The core concept of cell-to-cell communication in the nervous system is primarily centered around the mechanisms that neurons use to transmit signals to each other and to other types of cells. Neurons and glial cells are the two principal cell types involved in this process.
Communication between neurons occurs at the synapse: when an action potential reaches the end of an axon, it triggers the release of neurotransmitters into the synaptic cleft, which then bind to receptors on the post-synaptic neuron, potentially causing it to fire an action potential. This synaptic transmission can be modulated by the activity and support of glial cells, which have been traditionally seen as support cells but also have roles in modulating communication and maintaining homeostasis within the nervous system.
