Spine Anatomy

Learn about the common causes and structures of pain in the lumbar spine.

The cervical spine is comprised of six cervical discs that rest between the cervical vertebrae, act as shock absorbers in the neck, and allow the neck to handle much stress.

Cervical anatomy features eight cervical nerves (C1-C8) that branch off of the spinal cord and control different types of bodily and sensory activities.

This overview article discusses the cervical spine’s anatomy and function, including movements, vertebrae, discs, muscles, ligaments, spinal nerves, and the spinal cord.

The cervical vertebrae are critical to supporting the cervical spine’s shape and structure, protecting the spinal cord, and facilitating head and neck movement.

Explore treatments for the L3-L4 spinal segment, from non-surgical methods to surgical interventions.

Disorders of the L4-L5 motion segment are typically treated with nonsurgical methods. In case of medical emergencies, surgery may be considered.

Problems at the L5-S1 spinal motion segment are usually treated with nonsurgical methods. In case of certain medical emergencies, such as tumors or cauda equina syndrome, surgery may be recommended.

Explore the anatomy of lumbar discs, their unique features, and vital functions. Understand the role lumbar discs play in spinal flexibility and strength.
