A brain ventricle is a cavity in the brain with an open channel leading to it.
Explanation:
The brain and spinal cord are encased and protected by three layers of tissue, all called meninges. The outermost layer is called the dura mater, and covers both the brain and spinal cord. On either side of this layer, where it crosses or penetrates into these organs, are two extensions that look like small tubes coming from under a tent. These extensions are called cranial nerves because they come out on either side of the head just below its most prominent part - hence "cranial".

EXTERNAL:
Some teens may use narcotics due to peer pressure or troubled home issues (divorced parents, abusive parents, etc.). Some teens may choose not to use narcotics because they’re parents are very strict and they will punish the teen or the teen has friends telling them not to use drugs/narcotics.
