Introduction: The spinal meninges are the series of specialized membrane surrounding the spinal cord. It provides shock absorption and necessary physical stability. The nutrients and oxygen delivers to the spinal cord by the blood vessels that branching inside these layers.

Answer to Problem 1CRQ
Pictorial representation: The structure in the posterior view of the dissected spinal cord is labeled as the gray matter.
Fig.1: Posterior view of the dissected spinal cord.
Explanation of Solution
The gray matter is the main constituent of the central nervous system (CNS). It is dominated by neuroglia, the cell bodies of neurons, and unmyelinated axons. The narrow central canal is surrounded by the deep gray matter and form a butterfly or H-shape. The gray matter undergoes the growth and development throughout adolescence and childhood.
