The brain and spinal cord together make up the nervous system that is:

  1. Central
  2. Cellular
  3. Cervical
  4. Cortical
Show answer and solution

Correct answer: A. Central

1. Everything else forms the peripheral system. 2. These two structures sit at the core. 3. They form the central nervous system. _Source: OpenStax Anatomy and Physiology 2e, Chapter 12, The Nervous System and Nervous Tissue._

Nervous tissue contains glial cells and cells called:

  1. Nucleons
  2. Neurons
  3. Neutrons
  4. Nephrons
Show answer and solution

Correct answer: B. Neurons

1. One type does the electrical signalling. 2. The other supports and protects it. 3. The signalling cells are neurons. _Source: OpenStax Anatomy and Physiology 2e, Chapter 12, The Nervous System and Nervous Tissue._

The cells providing a supporting framework for neurons are called:

  1. Glial cells
  2. Goblet cells
  3. Granule cells
  4. Gamete cells
Show answer and solution

Correct answer: A. Glial cells

1. They do not carry the signals themselves. 2. They hold the tissue together and service the neurons. 3. They are the glial cells. _Source: OpenStax Anatomy and Physiology 2e, Chapter 12, The Nervous System and Nervous Tissue._
