Neural Impulses Pathways

Neural impulses are electrochemical signals that facilitate communication between neurons, allowing for the transmission of information throughout the nervous system. Neural pathways are the interconnected networks of neurons that process and relay these signals, enabling complex functions such as reflexes, sensory perception, and motor control.

Overview

Neural impulses and pathways are fundamental concepts in understanding how the nervous system operates. Neural impulses are electrical signals that travel along neurons, allowing communication between different parts of the body. These impulses are generated through action potentials, which are rapi...

Key Terms

Neuron
A nerve cell that transmits electrical signals.

Example: Motor neurons control muscle movements.

Action Potential
A rapid rise and fall in voltage across a neuronal membrane.

Example: Action potentials trigger muscle contractions.

Synapse
The junction between two neurons where communication occurs.

Example: Neurotransmitters are released at the synapse.

Neurotransmitter
Chemicals that transmit signals across a synapse.

Example: Dopamine is a neurotransmitter involved in reward.

Plasticity
The ability of the brain to change and adapt.

Example: Learning new skills can enhance neural plasticity.

Dendrite
Branch-like structures that receive signals from other neurons.

Example: Dendrites collect information from multiple sources.
