The provided text is a solution to a human central nervous system diagram question. What was the original question?

Okay Maths, let's break down this diagram of the human central nervous system.

2.4.1 Identify part:

• a) B: Cerebrum
• b) E: Medulla oblongata

2.4.2
The collective name for the membranes that protect the central nervous system is the meninges.

2.4.3 Give the LETTER and NAME of the part that:

• a) Interprets impulses received from the eye: B, Cerebrum
• b) Coordinates all voluntary actions: B, Cerebrum

2.4.4
Structure D is the spinal cord. An injury to the spinal cord would disrupt the transmission of nerve impulses between the brain and the muscles of the legs. This means the brain cannot send motor commands to initiate walking, and sensory information from the legs cannot reach the brain, resulting in the person being unable to walk.
