Final answer:
The three meninges that wrap the spinal cord from superficial to deep are the dura mater, arachnoid mater, and pia mater.
Step-by-step explanation:
The Three Meninges of the Spinal Cord
The spinal cord and brain are enclosed within three layers of protective tissues known as the meninges. These meningeal layers are, from superficial to deep:
- Dura mater - the outermost, thick, and durable membrane which forms a strong protective sheath around the central nervous system.
- Arachnoid mater - the middle layer, named for its web-like appearance, it forms a sac-like enclosure around the central nervous system.
- Pia mater - the innermost layer that closely adheres to the brain and spinal cord, following its contours closely.
The space between the arachnoid mater and the pia mater is filled with cerebrospinal fluid (CSF), which acts as a cushion and facilitates the distribution of nutrients and the removal of waste products.
