Answer 1

upper

Question 2

basal ganglia function

Answer 2

modifies and initiates movements

Question 3

lateral portion of telencephalon forms this

Answer 3

cerebral hemispheres

Question 4

basal part of blank forms the basal ganglia

Answer 4

telencephalon

Question 5

lenticular nucleus is made of these

Answer 5

putamen, globus pallidus

Question 6

striatum includes these

Answer 6

nucleus accumbens, caudate, putamen

Question 7

dark fibers that separate the caudate and putamen

Answer 7

internal capsule

Question 8

caudate and putamen connect via blank

Answer 8

ventral striatum

Question 9

the outer covering of the striatum

Answer 9

claustrum

Question 10

part of diencephalon that continues into the midbrain tegmentum

Answer 10

subthalamus

Question 11

direct pathway: globus pallidus internal and substantia nigra pars reticulata need to be blank in order for the thalamus to work

Answer 11

inhibited

Question 12

indirect pathway: globus pallidus external turns on this which turns on blank which inhibits blank

Answer 12

subthalamic nucleus, globus pallidus internal, thalamus

Question 13

indirect pathway has thalamus being blank

Answer 13

inhibited

Question 14

direct pathway has thalamus being blank

Answer 14

stimulated

Question 15

hyperkinetic diseases

Answer 15

balismus, huntingtons

Question 16

aka huntingtons

Answer 16

chorea

Question 17

damage to this is huntingtons

Answer 17

stratium (caudate and putamen)

Question 18

damage to this is ballismus

Answer 18

subthalamic nucleus

Question 19

damage to this is parkinsons

Answer 19

substantia nigra

Question 20

removing this by surgery could help with parkinsons

Answer 20

globus pallidus
