Answer 9

Speech production
Helps dictate how you say/form words
Located at Brodmann 44 and 45

Question 10

Broca’s Lesion/Injury

Answer 10

Agrammatical speech

Understand what’s being said but can’t fluently speak

In right frontal lobe

Controls emotional over-tone with spoken words

Question 12

Wernicke’s Area

Answer 12

Speech understanding

Located in temporal cortex

Question 13

Wernicke’s Lesion/Injury

Answer 13

Don’t understand what is being said to them

Trouble understanding language and finding correct words

Question 14

Primary Visual Cortex

Answer 14

Back of brain (Brodmann area 17)

Question 15

Cerebellum

Answer 15

Contributes to coordination, precision and accurate timing

Has narrow, ridge-like folds call “folia” (oriented transversely)

Question 16

Where does cerebellum receive input and what does it do with it?

Answer 16

From sensory systems of spinal cord and from other parts of brain
Takes inputs and makes them fine tune motor activity

Question 17

Cerebellum Location

Answer 17

Located in posterior cranial fossa

Below tentorium cerebella, behind pons and medulla

Question 18

What is the midline of the cerebellum and what does it do?

Answer 18

Vermis

Separates 2 lateral lobes or cerebellar hemispheres

Question 19

Midbrain

Answer 19

CN III and IV
CN V (part of)

Question 20

Pons

Answer 20

Connects cerebrum to both medulla and cerebellum
Part of CN V
CN VI, VII, CN VIII
Tiny part of CN X

Question 21

Medulla

Answer 21

CN V (part of)
CN VIII (part of)
CN IX, X, XI, XII

Question 22

Grey Matter Location

Answer 22

Ventral horn (lower motor neurons)
Dorsal horn (2nd order sensory neurons)
Lateral horn (sympathetic neurons)

Question 23

White Matter Location

Answer 23

Dorsal column (dorsal column tracks - sensory afferent)
Lateral column (corticospinal tract - moter efferent)
Ventral column (spinothalamic tract - general sensation afferent)
