Comprehensive Integrated Milady Assessment (CIMA) Practice Exam

A neuron is which of the following?

A nerve cell that transmits signals A glial cell that supports neurons The basic cell of the nervous system A muscle cell

Correct Answer:

The basic cell of the nervous system

Explanation:

Neurons are the basic cells of the nervous system. They are specialized for receiving, processing, and transmitting information through electrical and chemical signals, forming the networks that carry thoughts, sensations, and actions. That makes the statement about being the basic cell of the nervous system the best choice because it identifies neurons as the fundamental building blocks of nervous tissue. While neurons are indeed nerve cells that transmit signals, emphasizing their role as the basic cellular units clarifies their foundational place in the nervous system's structure and function. The other descriptions miss that core idea: glial cells provide support but are not neurons, and muscle cells belong to the muscular system and have a different primary function.
