Synaptic Transmission Takes Place When the Electrical Neural Impulse (Action

question 50

True/False

Synaptic transmission takes place when the electrical neural impulse (action potential)jumps across the fluid-filled synaptic cleft between neurons much like the spark from a sparkplug does in an automobile.

Definitions:

Spatial Summation

The process by which multiple neural inputs from different locations are combined at a single neuron, influencing its output.

Temporal Summation

A process by which multiple subthreshold signals can combine over time to trigger a significant response in a neuron.

Refractory Periods

Time intervals following an action potential during which a neuron is incapable of firing again or the threshold for firing is significantly raised.

Nerve Impulses

Electrical signals that travel along the nerves, enabling communication between the brain and the body.
