Spinal discs and ligaments An intervertebral disc (= intervertebral disk) represents the cartilaginous connection between two vertebral bodies. It consists of a connective tissue and cartilaginous outer ring, the so-called annulus fibrosus, and a soft inner gelatinous core, the nucleus pulposus. Intervertebral disc (intervertebral disc) – Discus inter vertebralis Gelatinous nucleus – nucleus pulposus Fiber … Spinal discs and ligaments | Anatomy of the spine

Ligamentous apparatus Numerous ligaments provide for a stabilization of the bony spine. These include the anterior and posterior longitudinal ligaments (Lig. longitudinale anterius and posterius), which run along the entire spinal column from cranial to caudal, the yellow ligaments (Ligamenta flava), which connect the adjacent vertebral arches, and the ligaments between the spinous processes (Ligamenta … Ligamentous apparatus | Anatomy of the spine

Nerves The spine forms a bony protective wall around the human spinal cord, through which nerve cords run that send electrical impulses to the muscles. Sensory perceptions are also conducted from the periphery via the spinal cord to the brain, where they can be consciously perceived. In order to reach the peripheral areas of the … Nerves | Anatomy of the spine

Nerve Root Nerve roots are fibers that enter or exit the spinal cord. On each section of the spinal column (segment) there are 2 nerve roots on the right and left side, one at the back and one at the front. The front roots transmit motor commands from the brain to the muscles, while the … Nerve Root | Anatomy of the spine

Thoracic Spine The thoracic spine consists of 12 vertebrae. The vertebral bodies gradually become higher and wider as they move toward the lumbar spine. The vertebral hole is approximately round and smaller than in the cervical and lumbar spine, the end faces are rounded and triangular. Since the spinous processes are long and strongly bent … Thoracic Spine | Anatomy of the spine

Sacral Spine The so-called sacrum originally consists of five independent vertebrae. After the birth, however, these merge uniformly to one in the view from the front triangular looking bone. Nevertheless, the sacrum still possesses all characteristics of a vertebra. The fused vertebrae form four T-shaped bone channels in the upper area, through which the sacral … Sacral Spine | Anatomy of the spine

Function of the spine The spine is an ingenious structure of the human body that enables many different functions.

A complex interplay of bony structures, ligaments and muscles makes it possible to stabilize the trunk, neck and head. … Function of the spine | Anatomy of the spine

Introduction The spine is our “support corset” of the upright gait. Ligaments, numerous small joints and auxiliary structures guarantee us not only stability but also a certain degree of flexibility. Structure of the spinal column Our spine is divided into the following different sections starting from the head: Cervical spine (HWS) Thoracic spine (BWS) Lumbar … Anatomy of the spine
