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. [2]: 424, 425 Each intervertebral foramen gives passage to a spinal nerve and spinal blood vessels, and lodges a ...
A cervical vertebra. (Vertebral foramen is the large hole at the center.) In a typical vertebra, the vertebral foramen is the foramen (opening) of a vertebra bounded ventrally/anteriorly by the body of the vertebra, and the dorsally/posteriorly by the vertebral arch. [1]: 421. In the articulated spine, the successive vertebral foramina of the ...
Cross-section through cervical spinal cord. 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 ...
In anatomy, Luschka's joints (also called uncovertebral joints, neurocentral joints) [1] are formed between uncinate process or "uncus" below and uncovertebral articulation above. [2] They are located in the cervical region of the vertebral column from C3 to C7. [3] Two lips project upward from the superior surface of the vertebral body below ...
Cervical spinal nerve 8. The plan of the cervical and brachial plexuses. The spinal cord with spinal nerves. The cervical spinal nerve 8 (C8) is a spinal nerve of the cervical segment. [1] It originates from the spinal column from below the cervical vertebra 7 (C7). [2]
In humans, cervical vertebrae are the smallest of the true vertebrae and can be readily distinguished from those of the thoracic or lumbar regions by the presence of a foramen (hole) in each transverse process, through which the vertebral artery, vertebral veins, and inferior cervical ganglion pass. The remainder of this article focuses upon ...
Cervical spinal nerve 1. The cervical spinal nerve 1 (C1) is a spinal nerve of the cervical segment. [1] C1 carries predominantly motor fibres, but also a small meningeal branch that supplies sensation to parts of the dura around the foramen magnum (via dorsal rami). It originates from the spinal column from above the cervical vertebra 1 (C1).
Spinal stenosis is an abnormal narrowing of the spinal canal or neural foramen that results in pressure on the spinal cord or nerve roots. [ 6 ] Symptoms may include pain, numbness, or weakness in the arms or legs. [ 1 ] Symptoms are typically gradual in onset and improve with leaning forward. [ 1 ]
