Researchers believe that these deep suboccipital muscles via the MDB perform important physiological roles such as preventing DM in folding, keeping the cerebellomedullary
cistern patent and maintaining the normal flow of cerebrospinal fluid (CSF),transmitting DM tension and adjusting head posture (Hack et al., 1995).
Since the spinal canal becomes narrow and results in cerebrospinal fluid reflux in such a condition, the tip of the catheter was inserted in the cerebellomedullary
Open the cisterna magna, lift up the cerebellar tonsil, separate arachnoid adhesions, and expose the forth ventricle through the cerebellomedullary
Abstract: Myelography was evaluated in 12 domestic pigeons (Columba livia) by injecting an iodinated contrast medium (iohexol) at the atlanto-occipital space into the cerebellomedullary cistern.
The site of injection was the atlanto-occipital space overlying the cerebellomedullary cistern (Fig 2).
Injection of iohexol into the cerebellomedullary cistern, which communicates with the subarachnoid space, was successful on the first attempt in 11 of the 12 pigeons.
