Central canal For the engineering project, see Indiana Central Canal. The central canal, also known as ependymal canal, is the cerebrospinal fluid-filled space that runs longitudinally through the length of the entire spinal cord. The central canal is continuous with the ventricular system of the brain. The fourth ventricle narrows at a region called the obex to become the central canal of the spinal cord. The central canal represents the adult remainder of the central cavity of the neural tube. It generally occludes (closes off) with age.

Spinal cord The spinal nerve is a mixed nerve, carrying sensory signals to the spinal cord by way of the posterior root and ganglion, and motor signals out to more distant parts of the body by way of the anterior root.

Syrinx of the Spinal Cord or Brain Stem Syrinx of the Spinal Cord or Brain Stem. NOTE: This is the Professional Version. A syrinx is a fluid-filled cavity within the spinal cord (syringomyelia) or brain stem (syringobulbia). Predisposing factors include craniocervical junction abnormalities, previous spinal cord trauma, and spinal cord tumors.

Spinal Cord The spinal cord is a long, fragile tubelike structure that begins at the end of the brain stem and continues down almost to the bottom of the spine (spinal column). The spinal cord consists of nerves that carry incoming and outgoing messages between the brain and the rest of the body. It is also the center for reflexes, such as the knee jerk reflex (see Figure: Reflex Arc: A No-Brainer). Like the brain, the spinal cord is covered by three layers of tissue (meninges). The spinal cord and meninges are contained in the spinal canal, which runs through the center of the spine. In most adults, the spine is composed of 26 individual back bones (vertebrae).

Living With a Spinal Cord Injury - Topic Overview A spinal cord injury is damage to the spinal cord. The spinal cord is a soft bundle of nerves that extends from the base of the brain to the lower back.It runs through the spinal canal, a tunnel formed by holes in the bones of the spine. The bony spine helps protect the spinal cord. spinal cord injury is damage to the spinal cord. The spinal cord is a soft bundle of nerves that extends from the base of the brain to the lower back.

Spinal Cord The spinal cord is a long, thin, tubular bundle of nerves that is an extension of the central nervous system from the brain and is enclosed in and protected by the bony vertebral column.The main function of the spinal cord is transmission of neural inputs between the periphery and the brain.he spinal cord is the main pathway for information connecting the brain and peripheral nervous system. The length of the spinal cord is much shorter than the length of the bony spinal column.

- However, MRI is currently by far the most. commonly used imaging method for the ac-. curate evaluation of spinal canal stenosis. MRI visualizes not only the width and length. of the spinal canal but also depicts in detail. the spinal cord, intervertebral disks, osteo-. phytes, and ligaments, all of which are po-. tential causes of spinal canal stenosis [2].

Morpheme (Words and Word Parts) 1 A word can be analyzed as consisting of one morpheme (sad) or two or more morphemes (unluckily; compare luck, lucky, unlucky), each morpheme usually expressing a distinct meaning. 2  When a morpheme is represented by a segment, that segment is a morph.djective: morphemic. Morphemes are the smallest units of meaning in a language. They are commonly classified as either free morphemes (which can occur as separate words) or bound morphemes (which can't stand alone as words). Many words in English are made up of a single free morpheme.

- The central canal runs through the center of the spinal cord and is filled with cerebrospinal fluid. A cross section of the spinal cord; the central canal runs through the center. A lumbar epidural steroid injection may be able to provide short-term relief from central canal stenosis.he central nervous system is compromised of the brain and spinal cord — the central canal is at the very center of the spinal cord. This canal runs from the conus medullaris in the lumbar spine to the end of the fourth ventricle, and is attached to the ventricle by the opex.

spinal cord Part of the central nervous system, the spinal cord is an ovoid column of nerve tissue 40 to 50 cm long that extends from the medulla to the second lumbar vertebra; it is within the spinal (vertebral) canal, protected by bone, and directly enclosed in the meninges.

Ventricular system From Wikipedia, the free encyclopedia. The ventricular system is a set of four interconnected cavities (ventricles) in the brain, where the cerebrospinal fluid (CSF) is produced. Within each ventricle is a region of choroid plexus, a network of ependymal cells involved in the production of CSF.The ventricular system is continuous with the central canal of the spinal cord (from the fourth ventricle) allowing for the flow of CSF to circulate.All of the ventricular system and the central canal of the spinal cord is lined with ependyma, a specialised form of epithelium.he ventricular system is continuous with the central canal of the spinal cord (from the fourth ventricle) allowing for the flow of CSF to circulate.

What is spinal cord in medical terminology? The spinal cord is a long, thin, tubular bundle of nerves that is an extension of the central nervous system from the brain and is enclosed in and protected by the bony vertebral column (aka. the back bones). The main function of the spinal cord is transmission of neural inputs between the periphery (legs, arms, torso, etc) and the brain. In summary, the term spinal cord is correct medical/anatomical language. There is no better way of naming this structure of the body.

- The cauda equina (CE) is a bundle of intradural nerve roots at the end of the spinal cord, in the subarachnoid space distal to the conus medullaris. Cauda is Latin for tail, and equina is Latin for horse (ie, the horse's tail).
