What is a Vertebrarterial Canal?
a. 1. (Anat.) Of or pertaining to a vertebra or vertebræ and an artery; – said of the foramina in the transverse processes of cervical vertebræ and of the canal which they form for the vertebral artery and vein.
What passes through intervertebral foramen?
spinal nerves
The intervertebral foramina which transmit the spinal nerves and the accompanying radicular arteries (which supply the spinal cord) are on the lateral aspect of the vertebral column.
What connects the laminae together?
The structure, or structures, that chiefly limit flexion of the vertebral column is the series of short ligaments that hold the laminae together, which are known collectively as the ligamentum flavum. The ligamentum flavum lies on the front of the laminae.
What is Flavum?
The ligamentum flavum, or the yellow ligament, is a thick, segmental ligament that runs between the lamina of adjacent vertebrae (Fig. 1-11). It begins on the undersurface of the inferior border of the lamina and courses down to the leading superior edge of the lamina (Fig. 1-12).
Which vertebra has an Odontoid process?
second cervical vertebrae
The odontoid process, or dens, is a superior projecting bony element from the second cervical vertebrae (C2, or the axis). The first cervical vertebrae (atlas) rotates around the odontoid process to provide the largest single component of lateral rotation of the cervical spine.
What is the difference between vertebral foramen and intervertebral foramen?
The vertebral foramen provides for passage of the spinal cord. Each spinal nerve exits through an intervertebral foramen, located between adjacent vertebrae. Intervertebral discs unite the bodies of adjacent vertebrae.
What is the Ligamenta Flava?
Description. The ligamenta flavum is a short but thick ligament that connects the laminae of adjacent vertebrae from C2 to S1 and is considered a medial ward continuation of the fact joint . It consists of 80% elastin fibers and 20% collagen fibers.
What Flavum means?
Ligamentum flavum literally means “yellow ligament,” and is so known because it has a yellow coloring due to the amount of elastin (a springy type of collagen). The elastin pulls the ligament out of the canal when the spine is extended.
What part of the spine controls your legs?
lumbar spine
Sacral region The lowest part of the spinal cord contains 5 pairs of nerves. These control the thighs, lower legs, and the genital and anal areas. Sacral nerve injury can happen anywhere from the upper lumbar spine down to the sacrum.
