Ground covers continue to be popular landscape plants in the Southeastern United States. The most popular ground cover for landscape use in the South is liriope. The three most popular liriope species grown in the Southeast are L. muscari (clumping), L. gigantea (giant) and L. spicata (spreading).
Understanding Spinal Anatomy: Intervertebral Discs. Between each vertebral body is a cushion called an intervertebral disc. Each disc absorbs the stress and shock the body incurs during movement and prevents the vertebrae from grinding against one another. The intervertebral discs are the largest structures in the body without a vascular supply. By means of osmosis, each disc absorbs needed nutrients.
The discs are like shock absorbers between the bones of the spine and are designed to help the back stay flexible while resisting terrific forces in many different planes of motion. Each disc has two parts: A firm, tough outer layer (anulus fibrosus). The outer portion of this layer contains nerves.
