Answer to Question 1

Ans:
A

Feedback:

The prognosis of people with pilocytic astrocytomas is influenced primarily by their location. The prognosis is usually better for people with surgically resectable tumors, such as those located in the cerebellar cortex, than for people with less accessible tumors, such as those involving the hypothalamus or brain stem. Because of infiltration of brain tissue that prevents total resection, surgery rarely cures brain tumors. The binary of malignant and benign is not used to characterize brain tumors, and the etiology and substantive risk factors are largely unknown. Brain tumors rarely metastasize outside the CNS.

Answer to Question 2

Ans:
C

Feedback:

Temporomandibular joint syndrome causes pain that originates in the temporomandibular joint and is usually referred to the face, neck, or ear. Headache is also common. It is aggravated by jaw function and can be particularly severe in people under stress, especially if they grind their teeth.
