Which of the following best describes the communication function of Purkinje cells?
Understand the Problem
The question is asking for the best description of the communication function of Purkinje cells from a set of multiple-choice options. This leads us to identify their role in the nervous system, specifically how they are involved in transmitting signals.
Answer
Purkinje cells use GABA to exert inhibitory influences on other cells.
The communication function of Purkinje cells primarily involves using the neurotransmitter GABA to exert strong inhibitory influences on the cells that receive their signals.
Answer for screen readers
The communication function of Purkinje cells primarily involves using the neurotransmitter GABA to exert strong inhibitory influences on the cells that receive their signals.
More Information
Purkinje cells play a significant role in the cerebellum's function, helping to modulate motor coordination by their inhibitory actions.
Tips
A common mistake is confusing Purkinje fibers in the heart with Purkinje cells in the brain. They have different functions.
