Textbook Question
Chapter 32, Problem 2CT
Most tumors that originate in the brain are not cancer, but growth of any tumor within the confined space of the skull can put pressure on .surrounding nervous tissue and thus harm neurons. Treating brain tumors with drugs is difficult because of the blood-brain barrier. Lipid-soluble drugs can penetrate this barrier, but they get into and affect all other cells too. Explain why.

Explain structure and function causes of brain damage and neurological disease
A brain tumor, known as an intracranial tumor, is an abnormal mass of tissue in which cells grow and multiply uncontrollably, seemingly unchecked by the mechanisms that control normal cells. Brain tumors also can happen near the brain tissue. Nearby locations include nerves, the pituitary gland, the pineal gland, and the membranes that cover the surface of the brain. If a brain tumor starts in a part of the brain that's less active, it might not cause symptoms right away. The brain tumor size could become quite large before the tumor is detected. Based on the description, please explain the types of brain tumors and the treatment of brain tumor associated with each type of therapy.
List all the layers that must be cut through to reach the tumor. During surgery to remove a tumor from the occipital lobe of the left cerebrum, a surgeon must cut into the brain to reach the tumor.
list all the ways to cure brain tumors
list all the variations of brain tumors while describing the anatomy of the brain
describe the effect of the tumor's locations within the brain (if the tumor was here this and this system would be effected and how)
