Subarachnoid space
Subarachnoid Space
The Subarachnoid Space (pronounced: suh-buh-rak-noyd space) is a significant anatomical structure in the human brain.
Etymology
The term "Subarachnoid Space" is derived from the Greek words "sub" meaning under, "arachne" meaning spider, and "oid" meaning like. This is due to the space's location beneath the arachnoid mater, one of the three meninges (protective coverings) of the brain and spinal cord, and its spider web-like appearance.
Definition
The Subarachnoid Space is the interval between the arachnoid mater and the pia mater, two of the three meninges that protect the brain and spinal cord. It is filled with cerebrospinal fluid (CSF), which provides a cushion for the brain, and is also where the major blood vessels that supply the brain are located.
