Question: 1 / 400

What is the term for the junction between nerve cells where the nerve impulse is transferred?

Dendrite

Axon

Synapse

The term for the junction between nerve cells where the nerve impulse is transferred is "synapse." A synapse is a specialized structure that facilitates communication between neurons. When an impulse travels down a neuron, it reaches the synapse, where neurotransmitters are released from one neuron and bind to receptors on another neuron, allowing the transmission of signals.

In contrast, dendrites are the branched extensions of neurons that receive incoming signals. Axons are elongated projections that transmit impulses away from the neuron, and neurons are the basic building blocks of the nervous system, consisting of a cell body, dendrites, and axons. Understanding the role of the synapse is crucial in the context of neural communication and the functioning of the nervous system.
