Answer to Question 1

Answer: A tumor is a mass of cells that grows in an uncontrolled manner and that serves no useful function. A benign tumor has no distinct border. In contrast, a malignant tumor is
encapsulated with a distinct border and can give rise to cells that form new tumors in different
parts of the body.

Answer to Question 2

Answer: The most common causes of seizure disorders are scarring of the brain secondary to an injury, a stroke, or a growing tumor. Withdrawal from alcohol or barbiturates can lead to seizure disorder. Alcohol blocks NMDA receptors, and these receptors may show rebound activation when alcohol use is terminated. Anticonvulsant drugs that enhance the effectiveness of brain inhibitory synapses are the chief treatment for seizure disorder. A focus that induces seizure can be removed through neurosurgery.
