Ligaments of the Vertebral Column. Now that we’ve looked at the vertebrae, and at the stuctures that hold them together, we’re almost ready to move on, to look at the principal muscles of the vertebral column. The major function of the vertebral column is to protect the spinal cord; it also is an attachment for many muscles. In humans, it further transmits body weight in walking and standing. We observed well-developed connective tissue ligaments connecting the lumbar dura to the spinal column and examined these tissues microscopically. An intervertebral disc is a secondary cartilaginous joint. Ligaments of the spine provide stability while allowing flexion, extension, and rotation. The ligaments of the vertebral column hold the vertebrae in place, preventing excess movement that could be damaging to the spinal cord, nerves, and surrounding tissue.

Single comprehensive reviews of the spinal ligaments are not found in the extant medical literature. The longitudinal ligaments of the spine serve this same purpose and work together to protect the intervertebral disc from punching out between the vertebral bones. 6. For this reason, it’s easier for these fibrous tissues to become torn from motions that abnormally twist, turn, stress, or overextend the spine. The denticulate ligaments, also known as dentate ligaments, are triangular shaped ligaments that anchor the spinal cord along its length, at each side, to the dura mater. Ligaments of Vertebral Column. This quiz has tags. Ligaments help to provide structural stability. Distinguish the spinal curves. The vertebrae are divided into three regions: cervical C1–C7 vertebrae, thoracic T1–T12 vertebrae, and lumbar L1–L5 vertebrae. 301– Median sagittal section of two lumbar vertebræ and their ligaments.

Ligaments of the Vertebral Column. An ex-employee @uber and @zomato X-rays provide an overall assessment of the bone anatomy as well as the curvature and alignment of the vertebral column. Spinal nerves are formed by the junction of ventral and dorsal nerve roots that are derived from their respective sides of the spinal cord. The lumbar spine is the lower back that begins below the last thoracic vertebra (T12) and ends at the top of the sacral spine, or sacrum (S1). The 3 spinal columns in traumatology according to Denis [ 1 ]: (a) Anterior column, (b) Medium column (with posterior annulus), (c) Posterior column Certain ligaments have a protective function of the spinal canal and thus of the neurological elements within (posterior longitudinal ligament (PLL), yellow ligament (ligamentum flavum)). • Describe the ligaments and soft tissues of the vertebral column and important features of an intervertebral disc. 1.03.2 | VERTEBRAL COLUMN TOPIC OUTLINE I. Vertebral 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 joints of the vertebral bodies are secondary cartilaginous joints (symphyses, singular: symphysis) designed for weight bearing and strength. The articulating surfaces of adjacent vertebrae are connected by intervertebral (IV) discs and ligaments. apical ligament. The cord extends from the skull to the lower back. The spinal cord and associated meningeal tissues have been removed to clearly demonstrate the ligaments of the vertebral column. The cervical vertebral foramen is opened revealing the spinal canal. Adjacent vertebrae are united by ligaments that run the length of the vertebral column along both its posterior and anterior aspects (). The meningeal branch of the spinal nerve (the sinuvertebral nerve) enters the vertebral canal and d … Interspinous ligaments - join spinous process of nearby vertebrae. Ligament Systems – Atlas and Axis As mentioned in the Vertebral Column, the Atlas (C1) and Axis (C2) are different from the other spinal vertebrae. IPAP A&P EXAM 4.

This strong ligament helps to maintain the stability of the joints between the vertebral bodies and helps prevent hyperextension of the vertebral column. Vertebral column, in vertebrate animals, the flexible column extending from neck to tail, made of bones called vertebrae. Articulations of the Vertebral Column. The mammalian vertebral column consists of five morphologically differentiated groups of vertebrae: cervical, thoracic, lumbar, sacral and coccygeal (caudal) (Fig 3.1). Soft tissue structures such as the spinal cord, spinal nerves, the disc and ligaments are usually not seen on X-rays, nor are most tumors, vascular malformations, or cysts. Adjacent vertebrae are united by ligaments that run the length of the vertebral column along both its posterior and anterior aspects (Figure 7.4.12). The bones of the vertebral column are held together by ligaments and muscles. Ligaments protect the bones and nerves of the spinal cord. The supraspinous ligament connects the spinous processes of the thoracic and lumbar vertebrae.
