Question 2

Answer 2

Tumours can compress the optic chiasm (loss of vision)

Question 3

Answer 3

Question 4

Answer 4

Question 5

Normally, we use contrast in the brain (T/F)

Answer 5

FALSE: it stays the same after contrast
Only pituitary glands and vessels enhance

Question 6

Question 7

Answer 7

Question 8

Wernicke is related to… speech
Broca is related to … speech

Answer 8

• understanding
• motor (knowing how to speak). If there is a problem here: AFASIA

They are connected, if there is a problem in the connection, no habrá congruencia entre lo que dice y lo que entiende.

Answer 10

Question 11

A lesion in this area might cause, problems in the contralateral… (hand/leg)

Answer 11

HAND (more lateral)

Question 12

Broca and Wernicke areas are only located in the… hemisphere

Answer 12

DOMINANT

Question 13

With MRI we can do functional imaging and identify the different areas of the brain (T/F)

Answer 13

True: to identify primary motor areas of the hand for example, if we have a tumour we do not see it.
We need the patient to cooperate, to see which area of the brain controls the movement (either speaking for Broca, or moving something for motor cortex).
