Spine Anatomy

The sciatic nerve has an intricate anatomy. This article describes its structure, pathway, function, and the role it plays in conditions like sciatica.

The sciatic nerve powers the leg muscles and plays a crucial role in movement, strength, and overall functionality of the lower limbs.

The coccyx serves as a vital insertion site for multiple soft tissues and helps with several movements and activities that involve the spine and legs to work together.

The muscles and ligaments of the lower back facilitate spinal movements, such as bending and twisting.

10% of adults have a congenital abnormality in their lower back, most commonly a sixth lumbar vertebra. Most of the time these anomalies cause no pain or problems, but there are exceptions.

Discover the connection between spinal anatomy and back pain. Learn about common causes and the essential structures involved in back and neck pain.

Learn about spinal cord anatomy and potential signs and symptoms that can develop if cord compression or injury occurs at the level of the cervical spine.

Terminal part of the spinal cord and cauda equina (nerve roots that descend from the spinal cord) are protected within the bony casing of the lumbar vertebrae.

Learn how spinal nerve roots function, and the potential symptoms of spinal nerve compression and pain in the neck and lower back.

Unveil the essentials of spinal discs, their composition, function, and role in back health. Understand how they can herniate or degenerate and contribute to back or neck pain.
