neurovälittäjät
Neurovälittäjät, also known as neurotransmitters, are chemical messengers that transmit signals across a synapse from one neuron to another, or to a target cell such as a muscle cell or gland. They are essential for the functioning of the nervous system, enabling communication between nerve cells.
The process begins when an electrical signal, an action potential, reaches the axon terminal of a neuron.
Common neurovälittäjät include acetylcholine, which plays a role in muscle contraction and memory; dopamine, associated with
Once their signal has been transmitted, neurovälittäjät are typically removed from the synaptic cleft through reuptake
