The central canal of the filum terminale in communicating hydrocephalus

Journal of Neurosurgery, 1980
✓ Lumbar thecoperitoneal shunting was carried out in patients with communicating hydrocephalus due to long-standing tuberculous meningitis. At the time of this surgical procedure, the filum terminale was excised to achieve filum terminostomy. The central canal of the excised filum terminale in seven hydrocephalic children and an equal number from ...

Root canal system of the maxillary central incisor

Journal of Endodontics, 1990
To better assess the efficacy of mechanical preparation of root canals, transparent specimens of 510 extracted maxillary central incisors were investigated for thickness and curvature of the root canal, condition of any accessory canals, and location of the apical foramen.

Where the central canal begins: endoscopic in vivo description

Journal of Neurosurgery, 2022
OBJECTIVE Although evidence and descriptions of the central canal (CC) along the medulla oblongata and the spinal cord have been provided by several anatomical and radiological studies, a clear picture and assessment of the opening of the CC, or apertura canalis centralis (ACC), into the fourth ventricle is ...

Centralized Scheduling Logic for Canal Operation

Journal of Irrigation and Drainage Engineering, 1991
Many schemes and devices have been developed and tested during the past three decades for automatic control of canal networks. Most of these have used local flow criteria to determine gate settings. Computer simulation of transient canal hydraulics has also been used to help test some of the ideas for canal automation, and in some cases the simulations

Location of Incisive Canal in Relation to Central Incisor Implants

Implant Dentistry, 1998
Computerized tomography (CT) scanning, now widely used for the diagnosis and treatment planning of dental implant sites, can be more specifically useful with integrated computer software. In this instance, the potentially critical incisive foramen area at the premaxilla is analyzed to better under stand its configuration and volume relative to the ...

Cervical Central Canal Occlusion Induces Noncommunicating Syringomyelia

Neurosurgery, 2012
Mechanisms underlying the development of noncommunicating syringomyelia are poorly understood.To assess the influence of focal arachnoiditis and central canal (CC) occlusion (CCO) on the formation of noncommunicating syringomyelia in the adult rat cervical spinal cord.

Hypothesis for Shared Central Processing of Canal and Otolith Signals

Journal of Neurophysiology, 1998
Green, Andrea M. and Henrietta L. Galiana. Hypothesis for shared central processing of canal and otolith signals. J. Neurophysiol. 80: 2222–2228, 1998. A common goal of the translational vestibuloocular reflex (TVOR) and the rotational vestibuloocular reflex (RVOR) is to stabilize visual targets on the retinae during head movement.

Central spinal cord lesions in stenosis of the cervical canal

Neuroradiology, 1990
34 patients suffering from cervical spondylotic myelopathy confirmed by myelography were examined by delayed CT 6-10 h after myelography. Twelve patients showed bilateral intramedullary collections of contrast medium, predominantly cranial to the stenosis.
