@med.ehsan: Every thought, movement, and memory begins with billions of neurons talking to each other. When an electrical signal reaches the end of a neuron, tiny sacs release neurotransmitters into the synaptic cleft. These chemical messengers cross the microscopic gap and bind to receptors on the next neuron, triggering a new electrical signal. This rapid electrochemical communication happens trillions of times every day, allowing your brain to process information almost instantly. 🧠 The synaptic cleft is only about 20–40 nanometers wide—around 2,500 times thinner than a human hair—yet this tiny gap is where every thought, emotion, memory, and voluntary movement is passed from one neuron to another. #Neuroscience #Synapse #Neurotransmitters #BrainFacts #MedicalEducation #Science #Medicine #Anatomy #Physiology #LearnSomethingNew #MedStudent #Shorts
