Neurons receive excitatory or inhibitory input from other cells or from physical stimuli like odorant molecules in the nose. Input information usually comes in through the dendrites.

Neuronen (oder Nervenzellen) sind spezialisierte Zellen, die elektrische Signale im Körper übertragen und empfangen. Neurone bestehen aus drei Hauptbestandteilen: Dendriten, einen Zellkörper und ein …

Explore the structure and function of neurons, the building blocks of the nervous system, and understand their role in transmitting signals.

Located in the cerebral cortex, these neurons follow specific pathways and their dysfunction can impact reflexes and muscle tone. Understanding their role is key to unraveling the complexities of our …

There actually are certain neurons where there isn't any gap--electrical synapses connect directly because electrical signals cannot travel through a gap. Chemical synapses need the synaptic cleft so …

This video introduces the structure and structural types of neurons. Explore the structure of neurons, their types, and functions. Uncover the roles of dendrites, axons, and the soma. Learn about the …

The most common cause of an excitatory graded potential in neurons is entry of sodium ions through neurotransmitter receptors that allow sodium ions to pass when the neurotransmitter is bound.
