DURA SPINALIS Meaning and
Definition
-
The term "dura spinalis" refers to the thick, tough, and fibrous outermost layer of the meninges that surrounds and protects the spinal cord. It is part of the central nervous system and serves as a protective covering to prevent damage to the delicate spinal cord tissue.
The dura spinalis is composed of dense connective tissue, primarily collagen fibers, which provide strength and resilience. It is located beneath the vertebral column and extends from the base of the skull down to the coccyx, enclosing the entire length of the spinal cord. This protective covering acts as a physical barrier against potential mechanical injuries, such as sudden impacts or excessive stretching of the spinal cord.
The dura spinalis has a vital role in maintaining the stability of the spinal cord within the spinal canal, preventing excessive movement and displacement that could lead to injury. It also contains cerebrospinal fluid (CSF), which acts as a cushion and shock absorber, further protecting the spinal cord from external forces.
In addition to its protective function, the dura spinalis also contains blood vessels that supply oxygen and essential nutrients to the spinal cord. These blood vessels help sustain the metabolic needs of the spinal cord and facilitate the removal of waste products.
Overall, the dura spinalis plays a crucial role in protecting and supporting the spinal cord, ensuring its proper functioning and preserving the integrity of the central nervous system.

Etymology of DURA SPINALIS
The term "dura spinalis" is not commonly used in Latin. It appears to be a combination of two anatomical terms: "dura" and "spinalis".
1. "Dura" comes from the Latin word "durus", meaning "hard" or "tough". It is derived from the Proto-Indo-European root *dʰreugh-, which means "to harden" or "to endure". In the context of anatomy, the term "dura" is often associated with the "dura mater", which is a tough membrane that covers the brain and spinal cord.
2. "Spinalis" comes from the Latin word "spina", meaning "thorn" or "spine". The term is derived from the Proto-Indo-European root *sp(h)ei-, which means "to fasten" or "to pierce".
