Here are seven ways that leis are made: Kui: This style is one of the most common, and it is made through a piercing method. The lei maker takes a needle and pierces the materials being used.
For the engineering project, see Indiana Central Canal. The central canal, also known as ependymal canal, is the cerebrospinal fluid-filled space that runs longitudinally through the length of the entire spinal cord.The central canal is continuous with the ventricular system of the brain.The fourth ventricle narrows at a region called the obex to become the central canal of the spinal cord.The central canal represents the adult remainder of the central cavity of the neural tube. It generally occludes (closes off) with age.he fourth ventricle narrows at a region called the obex to become the central canal of the spinal cord.

Purpose Cerebrospinal fluid is a clear liquid produced within spaces in the brain called ventricles. Like saliva it is a filtrate of blood. It is also found inside the subarachnoid space of the meninges which surrounds both the brain and the spinal chord.In addition, a space inside the spinal chord called the central canal also contains cerebrospinal fluid.he subarachanoid space lies between the arachnoid and pia mater. It is filled with cerebrospinal fluid. All blood vessels entering the brain, as well as cranial nerves pass through this space. The term arachnoid refers to the spider web like appearance of the blood vessels within the space.
