Arachnoid trabeculae

Definition

Arachnoid trabeculae are delicate, thread-like structures that connect the arachnoid mater to the pia mater within the subarachnoid space of the brain and spinal cord. They play a crucial role in supporting and stabilizing the cerebrospinal fluid (CSF) filled space between these two layers of the meninges.
