A Day in the Lab: Removing the Meninges from the Brain

🕒 Approximate reading time: 3 minutes

Invested in the intricacies of brain dissection, I devoted my day in the lab to the delicate procedure of removing the meninges. This task is a vital precursor to the harvesting of certain brain sections required for glial cell culture. Purging the meninges ensures that our cell cultures remain unadulterated by meningeal fibroblasts.

Shedding Light on the Meninges

Functioning as a protective envelope, the meninges comprise three membranes known as the dura mater, the arachnoid mater, and the pia mater, collectively safeguarding the brain and spinal cord. Their primary purpose is to shield the central nervous system from any external intrusions, thus ensuring its integrity and functionality.
