arachnoid membrane

Explanation:

Identify the root-like structures of a neuron

Using the Nervous System Terminology knowledge point

• Dendrites are the branching, root-like extensions of a neuron.
• They receive incoming signals (impulses) from other cells.
• They conduct these electrical impulses toward the cell body (soma).

Identify the innermost layer of the meninges

The meninges consist of three protective membranes surrounding the brain and spinal cord:

• Dura mater: The tough, outermost layer.
• Arachnoid membrane: The web-like middle layer.
• Pia mater: The delicate, innermost layer located nearest to the brain and spinal cord surface.
