Question

1. the three-layered membrane that covers the brain and spinal cord and literally means membrane is called the:

ganglion
ventricles
meninges
nerves

1. the cord-like structures that carry bio-electrical impulses from one part of the body to another are called:

ventricles
nerves
meninges
brain stem cells

Explanation:

Question 5

To solve this, we analyze each option:

• Ganglion: A cluster of nerve cell bodies, not a membrane covering brain/spinal cord.
• Ventricles: Cavities in the brain filled with cerebrospinal fluid, not a membrane.
• Meninges: The three - layered membrane (dura mater, arachnoid mater, pia mater) that covers the brain and spinal cord. The term "meninges" literally relates to membranes.
• Nerves: Cord - like structures for transmitting impulses, not a covering membrane.

We examine each option:

• Ventricles: As mentioned before, they are fluid - filled cavities in the brain, not for carrying bio - electrical impulses.
• Nerves: Cord - like structures that are responsible for carrying bio - electrical impulses (action potentials) from one part of the body to another.
• Meninges: A membrane covering the brain and spinal cord, not for impulse transmission.
• Brain stem cells: Stem cells in the brain, not related to carrying impulses.

Answer:

C. meninges
