- This is accomplished by inserting a spinal cage or structural bone graft into the vertebral interspace (the area between the two vertebral bodies where the disc is located) and then decorticating an area such as the facet joints and placing bone grafting material.

Spinal Syrinx Horrors A spinal syrinx is a potentially very serious anatomical abnormality that exists within the interior of the spinal cord itself.A syrinx is described as a fluid-filled hollow space within the cord, which sometimes expands and spreads in both length and width, slowly destroying the spinal cord.he spinal cord has a narrow space hollow which runs through the center. When a syrinx occurs, this cavity is abnormally filled with cerebral spinal fluid, expanding the space inside the spinal cord. A true syrinx is located at an interior location of the cord which is not lined with protective ependymal cells.

Hydromyelia Introduction: Hydromyelia. Description of Hydromyelia. Hydromyelia: Longitudinal cavities in the spinal cord, most often in the cervical region, which may extend for multiple spinal levels. The cavities are lined by dense, gliogenous tissue and may be associated with SPINAL CORD NEOPLASMS; spinal cord traumatic injuries; and vascular malformations.

Lymphatic Vessels Interstitial fluid. Interstitial fluid (ISF) or tissue fluid is a solution that bathes and surrounds the tissue cells of multicellular animals. It is the main component of the extracellular fluid, which also includes plasma and transcellular fluid. The interstitial fluid is found in the interstices - the spaces between cells (also known as the tissue spaces).

- Rating Newest Oldest. Best Answer: Intercalated discs are areas where cardiac muscle cells (among a few other cell types) are joined together. These discs contain gap junctions, which are small pores that connect the cytoplasm of one cell to the next. In other words, the membranes of the cells are fused together, and there are tiny holes that connect the interior of the adjacent cells.

Epidural space Inside the arachnoid is the subarachnoid space, which contains the cerebrospinal fluid, and the spinal cord. In the spine, the epidural space contains loose fatty tissue, and a network of large, thin-walled blood vessels called the epidural venous plexus.The upper limit of the epidural space is the foramen magnum, which is the point where the spinal cord enters the base of the skull.he epidural space is also of clinical interest since its cranial part contains vessels (e.g. the middle meningeal artery) susceptible to lesions after head traumas, causing a potentially lethal (if not treated immediately) collection of blood called an extradural or epidural hematoma.

- Hyperspace (science fiction) Hyperspace is a method of traveling sometimes used in science fiction. It is typically described as an alternative region of space co-existing with our own universe which may be entered using an energy field or other device. Travel in hyperspace is typically depicted as faster-than-light travel in normal space.

Medical Definition of Spinal cord Spinal cord injury: Trauma or damage to the spinal cord, the major column of nerve tissue that is connected to the brain and lies within the vertebral canal and from which the spinal nerves emerge. The spinal cord and the brain constitute the central nervous system. The spinal cord consists of nerve fibers that transmit impulses to and from the brain. Like the brain, the spinal cord is covered by three connective-tissue envelopes called the meninges.

Medical Definition of Spinal cord Spinal cord: The major column of nerve tissue that is connected to the brain and lies within the vertebral canal and from which the spinal nerves emerge. Thirty-one pairs of spinal nerves originate in the spinal cord: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal. The spinal cord and the brain constitute the central nervous system. The spinal cord consists of nerve fibers that transmit impulses to and from the brain. Like the brain, the spinal cord is covered by three connective-tissue envelopes called the meninges.

Velamentous Cord Insertion Velamentous Cord Insertion. Definition. Velamentous cord insertion abbreviated as VCI is an abnormal cord condition that happens during the pregnancy of a woman, in which the umbilical cord is noted to be inserted into the chorioamniotic membranes, as it travels within the membranes going to the placenta, just between the amnion and chorionic sites.

A to Z List of Neurological Disorders Syringomyelia (sear-IN-go-my-EEL-ya) is a chronic disorder involving the Spinal Cord in which a fluid filled cavity (or cyst) forms within the Spinal Cord. This cyst (called a Syrinx) expands and elongates over time, destroying the center of the Spinal Cord. As the nerve fibers inside the Spinal Cord are damaged, a wide variety of symptoms can occur, depending upon the size and location of the Syrinx.

Spinal cord The spinal cord (and brain) are protected by three layers of tissue or membranes called meninges, that surround the canal. The dura mater is the outermost layer, and it forms a tough protective coating. Between the dura mater and the surrounding bone of the vertebrae is a space called the epidural space.or the nerves of the lower spinal cord, this means that they exit the vertebral column much lower (more caudally) than their roots. As these nerves travel from their respective roots to their point of exit from the vertebral column, the nerves of the lower spinal segments form a bundle called the cauda equina.
