Synaptic Transmission

Synaptic transmission is the process by which neurotransmitters are released from the presynaptic neuron and bind to receptors on the postsynaptic neuron, facilitating communication between neurons. This transmission is crucial for neuronal signaling, influencing various physiological and behavioral functions in the nervous system.

Overview

Synaptic transmission is a fundamental process in the nervous system that allows neurons to communicate with each other. It involves the release of neurotransmitters from one neuron, which then bind to receptors on another neuron, leading to either excitation or inhibition of that neuron. This proce...

Key Terms

Neuron
A nerve cell that transmits electrical signals in the body.

Example: Motor neurons control muscle movements.

Synapse
The junction between two neurons where communication occurs.

Example: The synapse allows neurotransmitters to pass signals.

Neurotransmitter
Chemicals that transmit signals across a synapse.

Example: Dopamine is a neurotransmitter linked to pleasure.

Action Potential
An electrical impulse that travels down a neuron.

Example: An action potential triggers neurotransmitter release.

Receptor
A protein on a neuron that binds to neurotransmitters.

Example: Dopamine receptors respond to dopamine.

Reuptake
The process of neurotransmitters being reabsorbed by the neuron.

Example: Reuptake helps regulate neurotransmitter levels.
