Study Notes
Spinal Cord Anatomy and Associated Structures
- Spinous Process of Vertebra: A bony projection off the posterior of each vertebra, serving as an attachment point for muscles and ligaments and providing stability to the spine.
Meninges
- Dura Mater: The tough outermost layer of the meninges, providing a protective covering for the brain and spinal cord.
- Arachnoid Mater: The middle layer of the meninges, characterized by its web-like appearance. It lies between the dura mater and pia mater, cushioning the central nervous system.
Pia Mater
- Pia Mater: The delicate innermost layer of the meninges, directly adhering to the surface of the brain and spinal cord, aiding in the protection and nourishment of neural tissue.
Supportive Structures
- Denticulate Ligament: A slender band of pia mater that extends from the spinal cord to the dura mater, providing lateral stability and anchoring the spinal cord within the vertebral column.
Spinal Cord Spaces
- Epidural Space: The space between the dura mater and the vertebral wall filled with adipose tissue and blood vessels, providing cushioning and support for the spinal cord.
- Subarachnoid Space: Located between the arachnoid mater and pia mater, this space contains cerebrospinal fluid (CSF) that bathes the spinal cord and provides shock absorption.
Anatomy Features
- Web-like Projection of Arachnoid Mater: Refers to the delicate trabecular structure of the arachnoid, facilitating the flow of cerebral spinal fluid and acting as a barrier to protect the central nervous system.
Vertebral Components
- Body of Vertebra: The large, cylindrical part of a vertebra that bears weight and provides structural support to the spinal column, integral in distributing mechanical load during movement.
