Question

State where in human body central canal is located and also state its main function.

Answer 1

Central canal:

1. The central canal (also known as the spinal foramen or ependymal canal) is a channel filled with cerebrospinal fluid that travels through the spinal cord.
2. The central canal is located below and is related to the brain's ventricular system, from which it gets cerebrospinal fluid, and it has the same ependymal lining.

Location:

1. The central canal's position in relation to the midpoint of the spinal cord changes depending on the region of the cord.
2. The cervical and thoracic segments are slightly ventral, the lumbar area segments are central, and the conus medullaris is dorsal.

Function:

1. The central canal transports cerebrospinal fluid (CSF), which comes from the brain's ventricular system.
2. When the spine is injured, the central canal helps to transfer nutrients to the spinal cord while also protecting it by softening the effect of a force.
