What is the normal diameter of the spinal canal?
The normal diameter of the spinal canal varies by region but generally ranges from about 13 to 15 millimeters in the cervical spine, 15 to 25 millimeters in the thoracic spine, and about 25 to 30 millimeters in the lumbar spine. A diameter of less than 10 millimeters in any region may indicate spinal stenosis, which can lead to neurological symptoms. Variations can occur based on individual anatomy and age.
What does central canal stenosis ap diameter is 9mm mean?
Central canal stenosis with an anterior-posterior (AP) diameter of 9mm indicates a narrowing of the central spinal canal, which is the space within the spine that houses the spinal cord and nerve roots. An AP diameter of 9mm is generally considered to be below the normal range, potentially leading to compression of the spinal cord or nerves. This condition can result in symptoms such as pain, numbness, or weakness in the extremities, depending on the severity and location of the stenosis. Evaluation by a healthcare professional is recommended for appropriate management.
What is normal cervical AP dimension?
The normal cervical anteroposterior (AP) dimension can vary depending on the specific level of the cervical spine being measured, but generally, the AP diameter of the cervical canal is around 10 to 14 millimeters in adults. A dimension less than 10 millimeters may indicate potential spinal stenosis, which could lead to neurological issues. It's important to evaluate these measurements in the context of individual anatomy and any existing clinical symptoms.
What spinal canal diameter is a spinal stenosis indicator?
The spinal canal is usually more than 0.5 in (12 mm) in diameter. A smaller diameter indicates stenosis. The diameter of the cervical spine ranges is 0.6-1 in (15-12 mm). Any opening under 0.5 in (13 mm)in diameter is considered evidence of stenosis.
What diameter is the central canal?
The diameter of the central canal in the spinal cord typically ranges from 0.5 to 1 millimeter, although this can vary among individuals. The canal is a narrow, fluid-filled space that runs longitudinally through the center of the spinal cord and contains cerebrospinal fluid. Its primary function is to protect and nourish the spinal cord while allowing for the circulation of this fluid.
Longitudinal canal carrying blood vessels and nerves?
The central, or Haversian, canal. The canal runs through the core of each osteon.

Which of these parts of vertebral canal will show concavity backward in secondry curvature- either cervical or thoracic?
cervical curvature
The junction of the uterine cavity with the cervical canal is?

Which structure represents the longest portion of the birth canal?
cervical
C7-t1 What is patent central canal and neural foramen?
It means the canal and foramina are normal in size and allows for nerves to pass through freely without restriction.
What is Central canal and neural foramina are grossly patent throughout?
This means that the openings in the canal and foramina are normal in size, thus there is no restrictions that would cause any nerve problems.
