Question: 1 / 400

What are neurotransmitters?

Hormones released by glial cells

Chemical messengers traveling across the synapse

Neurotransmitters are indeed chemical messengers that travel across the synapse, which is the gap between two neurons. When a neuron is activated, it releases neurotransmitters into the synaptic cleft, where they bind to specific receptors on the next neuron. This binding can result in the initiation of an electrical impulse in the receiving neuron, facilitating communication throughout the nervous system.

This process is crucial for a range of functions, including mood regulation, cognition, motor control, and overall neural communication. The action of neurotransmitters is central to how signals are transmitted in the brain and body, making them fundamental components of neural activity.

Understanding this role highlights the importance of neurotransmitters in psychological processes, as imbalances or disruptions in their signaling can lead to various mental health disorders and cognitive impairments.
