In the articulated spine, the successive vertebral foramina of the stacked vertebrae (together with adjacent structures) collectively form the spinal canal (vertebral canal) which lodges the spinal cord and its meninges as well as spinal nerve roots and blood vessels. [1]: 452
The vertebral canal is enclosed anteriorly by the vertebral bodies, intervertebral discs, and the posterior longitudinal ligament; it is enclosed posteriorly by the vertebral laminae and the ligamenta flava; laterally, it is incompletely enclosed by the pedicles with the interval between two adjacent pedicles on either side creating an intervertebral foramen (allowing the passage of the spinal ...
The body of the vertebra and the vertebral arch form the vertebral foramen, the larger, central opening that accommodates the spinal canal, which encloses and protects the spinal cord. Vertebrae articulate with each other to give strength and flexibility to the spinal column, and the shape at their back and front aspects determines the range of ...
hypoglossal canal: 2-hypoglossal nerve (XII) occipital: posterior cranial fossa: foramen magnum: 1: anterior and posterior spinal arteries, vertebral arteries: lowest part of medulla oblongata, three meninges, ascending spinal fibers of accessory nerve (XI) [3] occipital: posterior cranial fossa: condylar canal: 1
In humans, the spinal cord is a continuation of the brainstem and anatomically begins at the occipital bone, passing out of the foramen magnum and then enters the spinal canal at the beginning of the cervical vertebrae. The spinal cord extends down to between the first and second lumbar vertebrae, where it tapers to become the cauda equina. The ...
The central canal (also known as spinal foramen or ependymal canal) is the cerebrospinal fluid-filled space that runs through the spinal cord. [1] The central canal lies below and is connected to the ventricular system of the brain, from which it receives cerebrospinal fluid, and shares the same ependymal lining. The central canal helps to ...
The intervertebral foramen (also neural foramen) (often abbreviated as IV foramen or IVF) is an opening between (the intervertebral notches of [1]) two pedicles (one above and one below) of adjacent vertebra in the articulated spine.
Omental foramen, the connecting opening between the greater sac and the lesser sac in the abdominal cavity. Sacral foramina, which perforate the vertebral canal from the Sacrum (sacral bone), and through which the sacral nerves pass. Vertebral foramen, the foramen formed by the anterior segment (the body), and the posterior part, the vertebral ...
