The part of the spinal cord where interneurons are present is called:
Correct answer: B. Gray matter
- A. White matter
- B. Gray matter
- C. Lumbar enlargement
- D. Cervical enlargement
Explanation
Gray matter in the spinal cord is neural tissue that is dominated by the cell bodies of neurons, neuroglia, and unmyelinated axons and surrounds the narrow central canal. It is neural tissue that contains large numbers of myelinated and unmyelinated axons. Interneurons are present in the gray matter, surrounded by white matter.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
