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 ...
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 ...
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 ]
The interventricular foramina are two holes (Latin: foramen, pl. foramina) that connect the left and the right lateral ventricles to the third ventricle. [1]They are located on the underside near the midline of the lateral ventricles, [2] and join the third ventricle where its roof meets its anterior surface. [3]
The foramen magnum (Latin: great hole) is a large, oval-shaped opening in the occipital bone of the skull. It is one of the several oval or circular openings (foramina) in the base of the skull . The spinal cord , an extension of the medulla oblongata , passes through the foramen magnum as it exits the cranial cavity .
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 ...
Drawing of a cast of the ventricular cavities, viewed from the side. The cerebral aqueduct (aqueduct of the midbrain, aqueduct of Sylvius, Sylvian aqueduct, mesencephalic duct) is a small, narrow tube connecting the third and fourth ventricles of the brain. [1][2] The cerebral aqueduct is a midline structure that passes through the midbrain.
In anatomy and osteology, a foramen (/ f ə ˈ r eɪ m ən /; [1] [2] pl.: foramina, / f ə ˈ r æ m ɪ n ə / or foramens / f ə ˈ r eɪ m ən z /; from Latin 'an opening produced by boring') is an opening or enclosed gap within the dense connective tissue (bones and deep fasciae) of extant and extinct amniote animals, typically to allow passage of nerves, arteries, veins or other soft ...
