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.
Excess cerebrospinal fluid in the central canal of the spinal cord is called hydromyelia. This term refers to increased cerebrospinal fluid that is contained within the ependyma of the central canal. When fluid dissects into the surrounding white matter forming a cystic cavity or syrinx, the term syringomyelia is applied. As these conditions ...
Myelomalacia affects the neurological functions in the spinal cord. Once breached, the ramification of the damage directly affects the motor functions of the body. Because the central nervous system is affected, the condition is classified under the neurological field of study. [citation needed] The spine shown here with spinal cord.
Cerebrospinal fluid fills the syrinx. Pressure differences along the spine cause the fluid to move within the cyst. Physicians believe that it is this continual movement of fluid that results in cyst growth and further damage to the spinal cord. In the case of syringomyelia, the syrinx can expand and elongate over time, destroying the spinal ...
Magnetic resonance imaging alias Nuclear magnetic resonance : high strength (0.15 to 1.5 teslas) [4] are used to excite protons that produce the record results (like CT scan). It can show particular tissues more clearly than CT.; [4] video link: Linear accelerator: used in radiotherapy for cancer: Functional magnetic resonance imaging (fMRI ...
EOS is a medical imaging system designed to provide frontal and lateral radiography images, while limiting the X-ray dose absorbed by the patient in a sitting or standing position. The system relies on the high sensitivity of a detector ( multi-wire chamber ) invented by Georges Charpak , which earned him the 1992 Nobel Prize .
Positron emission tomography (PET) [1] is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption.
Each Haversian canal generally contains one or two capillaries and many nerve fibres. The channels are formed by concentric layers called lamellae , which are approximately 50 μm in diameter . The Haversian canals surround blood vessels and nerve cells throughout bones and communicate with osteocytes (contained in spaces within the dense bone ...
