Canal that connects the third and fourth ventricles is cerebral aqueduct (of Sylvius) canal.
<h3>What are the central canal?</h3>
The central canal, additionally known as the spinal foramen or ependymal canal, extends from the conus medullaris withinside the lumbar backbone to the caudal perspective of the fourth ventricle and is coated through a single layer of columnar ependymal cells . It represents the remnant of the lumen of the primitive neural tube.
The 3 ventricle is a slim, funnel-formed shape located among your proper and left thalamus, simply above your mind stem. The fourth ventricle is a diamond-formed shape that runs along your mind stem.

The two sides of a nerve cell membrane have unequally distributed ions ( Na+ and K+). Sodium is inside, while potassium is outside. Carriers actively transport them. This active transport mechanism is called Sodium-Potassium Pump. Without stimulus, sodium channels are closed while some of the potassium channels are open.
Stimulus (depolarization) will cause the sodium channels to briefly open and the positively-charged ion diffuses into the nerve cell. The membrane potential becomes positive. The potassium channels open and positively-charged potassium diffuse out. With respect to the outside, the inside will become less positive again.
