Anatomy of the vertebral column

Vertebral Column: Definition, Diagram, Functions & Parts

A vertebral segment is a fundamental, repeating functional unit of the spinal column. This assembly allows for both flexibility and stability. Understanding this unit helps explain remaining vertebrae is how the entire spine operates and supports the body. Core Components of a Vertebral Segment A vertebral segment primarily consists of two adjacent vertebrae, separated by an

Vertebral Column Vertebral column also known as spinal column, backbone or spine, It is formed by 26 serially arranged bones called vertebrae and is dorsally placed. These structures play a crucial role in forming the vertebral foramen, the passageway for the spinal cord¹⁻². Vertebral Pedicles Function in the Spinal Column The primary function of vertebral pedicles is to protect the spinal cord

The spinal cavity, also known as the vertebral cavity or spinal canal, is a tubular structure that runs the length of the vertebral column. It is formed by the vertebrae of the spine and houses the spinal cord and the beginnings of spinal nerves. The vertebral column is also known as the spinal column or spine (Figure 10.10.1). It consists of a sequence of vertebrae (singular = vertebra), each of which is separated and united by an intervertebral disc. Together, the Test your knowledge on the anatomy and functions of the vertebrae in the human spine. This quiz covers key features and differences among cervical, thoracic, and lumbar vertebrae, as well as associated structures like intervertebral discs. Challenge yourself to understand the unique characteristics and classifications within vertebral anatomy.

The vertebrae and accompanying intervertebral discs are the basic skeletal components that make up the back. The skull, pelvic bones, scapulae and ribs contribute to the back skeletal structure and serve as attachment points for muscles. Here, let’s learn more about the anatomy and functions of vertebrae in the human body. Table of Contents Vertebrae Anatomy Vertebral that runs Regardless of which division they belong to, all typical vertebrae share a common structure and each vertebra certainly contains the following structures: Vertebral body (corpus vertebrae) Vertebral body (corpus vertebrae) Vertebral arch (arcus vertebrae) Vertebral arch (arcus vertebrae) Between the body and the arch lies the vertebral foramen (foramen vertebrale).

Structure and Function As with all physiology, the anatomy of a structure is related directly to its function. The lumbar vertebrae have the largest bodies of the entire spine and progressively increase in size, moving more inferiorly. This marked increase in size reflects the responsibility of the lumbar spine to support the weight of the entire upper body. Due to the

Projecting thick and strong from both sides, they meet at the posterior side of the bone, forming the vertebral arch. This forms the central opening or vertebral foramen at the center of the axis, allowing the spinal cord to pass. The vertebral arch takes care of one of the most important functions of the bone, which is keeping the The vertebral column originally develops as a series of 33 vertebrae, but this number is eventually reduced to 24 vertebrae, plus the sacrum and coccyx. The human spine, or vertebral column, is the most important anatomical and functional axis of the human body.

Fish vertebrae have a round vertebral body called centrum, endplates with a marked biconcavity, and a dorsally located neural arch that encloses the spinal cord (Rockwell et al., 1938). In most cases, a ventral vertebral arch called the hemal

In this article, we discuss the osteology of the vertebral column, identify the different regions of the spine, and discuss clinically relevant examples.

Your spine is the body’s central support structure which provides stability and flexibility while also protecting the spinal cord and nerves. Spinal Column and Structure of the Spine The spinal column, also known as the Dysfunction or injury to the vertebral column can lead to various conditions and disorders, including spinal cord injuries, herniated discs, and scoliosis. The function, structure, and clinical significance of the vertebral column will be examined in this article. Structural and functional components of intervertebral joints, the role of intervertebral discs in weight-bearing and common disc lesions. Regions and functions of the vertebral column including range of movement of the entire column and its individual regions. Functional roles of ligaments of vertebral column.

The vertebra consists of the vertebral body anteriorly, the neural arch posteriorly and a series of processes that serve as connection points for ligaments and muscles. The outer shell of the vertebra is mainly cortical bone and the inner region a network of cancellous bone. While we knew much in 1990 about the form and function of the spinal vertebrae, substantial research over the

The first two cervical vertebrae are the only vertebrae that deviate from the basic outer structure of the vertebrae. The bony structure of the remaining vertebrae is fundamentally similar. The vertebrae are composed of the following structures: Introduction Computer-generated lateral three-dimensional (3D) image of substantial research over the the thoracolumbar spine shows the components of the anterior (yellow) and posterior (orange) spinal motion segments [1] Diagram depicting a midline sagittal cut of vertebrae with intact ligamentous structures. Ligaments of interest are outlined. The ligamentum flavum (red) forms the posterior wall of the vertebral

The vertebral column supports the body’s physical structure and nervous system, enabling movement and sensation. Pathology of the spine can lead to debilitating outcomes on quality of life. The vertebral column (spine) defines the animal subphylum Vertebra, or vertebrates, of the phylum Chordata. In humans, it is composed of 33 vertebrae that include 7 cervical, 12

Joints and ligaments of the vertebral column

Posterior Arch As the name suggests, it is the posterior three-fourth part of the ring of the atlas that encloses the vertebral foramen. The thin band of bone has a slightly wider prominence at its apex in the back, known as

Lamina: The flattened portion of the vertebral arch that forms the posterior wall of the vertebral canal. This structure provides attachment for ligaments and protects the spinal cord. Transverse process: Lateral projections that serve as attachment points for muscles and contain the foramen transversarium.

The facet joints, also known as zygapophyseal joints, represent crucial articulations between vertebral segments that guide spinal movement while maintaining stability. These specialized synovial joints demonstrate complex biomechanical properties that vary by spinal region, making their understanding essential for medical professionals involved in spine The central canal, also known as the central spinal canal or the vertebral canal, is a cylindrical channel that runs the length of the spinal cord. It is located at the center of the vertebral column and is surrounded by the vertebral arches, which are bony structures that form the spinal column’s protective framework. The vertebral foramen is the central opening formed by the vertebral arch and body. Together with the foramina of other vertebrae, it creates the spinal canal, which houses and protects the spinal cord and cauda equina in this region.

The vertebral arch is made up of two bony processes, called the pedicles and laminae, that project out from the vertebral body. The pedicles and laminae join together at the back of the vertebral body to form the vertebral arch, which encloses the spinal canal. The spinal canal is not a continuous, straight tube.

The vertebral column consists of several joints that permit various movements of the column. These joints are typically organized into the joints of the vertebral bodies, joints of the vertebral arches, craniovertebral joints, costovertebral joints, and the sacroiliac joints. The vertebral column supports the body’s physical structure and nervous system, enabling The spinal cavity movement and sensation.
