What are the ligaments of vertebral column?

The ligaments are strong fibrous bands that hold the vertebrae together, stabilize the spine, and protect the discs. The three major ligaments of the spine are the ligamentum flavum, anterior longitudinal ligament (ALL), and posterior longitudinal ligament (PLL) (Fig.

What are the 5 spinal ligaments?

There are five main ligamentous structures seen throughout the spinal column:

• Anterior Longitudinal Ligament (ALL)
• Posterior Longitudinal Ligament (PLL)
• Ligamentum Flavum.
• Interspinous ligaments.
• Supraspinous ligament[1]

What are the names of the 4 processes in the vertebral column?

Arising from the vertebral arch are the transverse, spinous, superior articular, and inferior articular processes. The vertebral foramen provides for passage of the spinal cord. Each spinal nerve exits through an intervertebral foramen, located between adjacent vertebrae.

What are the ligaments in the neck?

There are many ligaments in the neck, but 3 types are important for helping to stabilize the entire spine:

• Anterior longitudinal ligament (ALL).
• Posterior longitudinal ligament (PLL).
• Ligamentum flava.

How many ligaments are in the neck?

There are six major ligaments to consider in the cervical spine.

What are the 5 sections of the vertebral column?

The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.

Which region of the vertebral column is most flexible?

cervical spine
The most flexible part is the cervical spine (neck area). The bones that make up the spine also protect the spinal cord, which runs through the spinal canal.

What is the cruciform ligament?

The cruciform ligament of atlas (cruciate may substitute for cruciform) is a cruciate ligament in the neck forming part of the atlanto-axial joint. The ligament is named as such because it is in the shape of a cross. It consists of two bands: Longitudinal band.

What is posterior longitudinal ligament?

The posterior longitudinal ligament connects and stabilizes the bones of the spinal column. It runs almost the entire length of the spine, from the 2nd vertebra in the cervical spine (neck) all the way down to the sacrum (end of the spine). The ligament is adjacent to the spinal cord.

Where are the cruciate ligaments?

Cruciate Ligaments These are found inside your knee joint. They cross each other to form an “X” with the anterior cruciate ligament in front and the posterior cruciate ligament in back. The cruciate ligaments control the back and forth motion of your knee.

Where are the ligaments located in the vertebral column?

The posterior longitudinal ligament runs inside the vertebral canal along the posterior surface of the vertebral bodies, from C2 to the sacrum. Its main function is to prevent posterior herniation of the intervertebral discs. Adjacent vertebral arches are connected by synovial joints called zygapophysial (facet) joints.

How are adjacent vertebrae United in the vertebral column?

Adjacent vertebrae are united by ligaments that run the length of the vertebral column along both its posterior and anterior aspects (Figure 12). These serve to resist excess forward or backward bending movements of the vertebral column, respectively.

How are the arches of the vertebral column strengthened?

The vertebral arches are strengthened by several accessory ligaments: Ligamenta flava – connecting adjacent laminae. They prevent separation of the lamina during sudden flexion of the vertebral column. Interspinous ligaments – join spinous process of nearby vertebrae.

How does the spinal cord support the vertebral column?

Together, the vertebrae and intervertebral discs form the vertebral column. It is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord, which passes down the back through openings in the vertebrae. Figure 1. Vertebral Column.
