Flashcards in Final Exam Random Deck (26):
1

Make up the neostriatum:

Caudate Nucleus
Putamen Nucleus

2

Make up the Corpus striatum:

Caudate nucleus
Putamen nucleus
Globus pallidus or paleostriatum

3

Make up the Basal Ganglia:

Caudate Nucleus
Putamen nucleus
Globus pallidus
Amygdaloid complex or archistriatum

4

Putamen & globus pallidus together are called the:

Lenticular (lentiform) nucleus

5

Striatal lesions normally lead to:

Dyskinesia (muscle tone disturbances)

6

Results in a brisk series of graceful involuntary movements of extremities, facial muscles, tongue

Huntington's Chorea

7

The corpus striatum begins to deteriorate. Its seems to be a genetic deficiency of GABA

Huntington's chorea

8

Violent movement, occurring from lesions to the globus pallidus

Ballism or hemiballism

9

- Parts include a head, body, tail
- Has both afferent & efferent fibers

Caudate Nucleus

10

AFFERENT (of the Caudate) fibers synapse in the:

ALL lobes of the cortex, the thalamus, substantia nigra, & putamen

11

EFFERENT (of the caudate & putamen nuclei) output fibers extend to the:

Putamen, globus pallidus, substantia nigra & the thalamus

12

- Most lateral of the corpus striatal nuclei
- Contains Afferent & efferent fibers also

Putamen nucleus

13

AFFERENT fibers (of the putamen) synapse in the:

- ALL lobes of the cortex, the thalamus, substantia nigra, & putamen
- Find an abundance of "dopamine"

14

- Part of the lenticular nucleus along w/ putamen
- A medial medullary lamina separates it into medial & lateral segments
- Also contains Afferent & Efferent fibers

Globus Pallidus

15

AFFERENT fibers (often called pallidal fibers) from the globus pallidus includes axons from the:

Caudate nucleus
Putamen Nucleus
Subthalamic nucleus

16

EFFERNT fiber of the globus pallidus (often called pallidalfugal fibers)

They represent the primary efferent outflow from the corpus striatum. Most go to the anterior aspect of the thalamus

17

Amygdala plays a role with?

Memory of emotional reactions

18

What is the name given to the collective white matter of the telencephalon?

Centrum Semiovale

19

Fiber types in the white matter:

Projection axons
Commissural axons
Association axon bundles

20

- Afferent & efferent fibers
- Most travel in the corona radiate & internal capsule

Projection axons

21

Apart of the commissural axons

Corpus callosum

22

- Only found in placental mammals
- Parts include splenium, body, genu, rostrum, forceps anticus, forceps posticus & tapetum

Corpus callosum

23

Lesions & surgery on the corpus callosum can lead to:

Alien hand syndrome - you have no control over your non dominate hand

24

- Most abundant part of the white matter
- Contains both Short & long fibers

Association axon bundles

25

Connect adjacent or near gyri - just inward from the gray cortex

Short fibers from the association axon bundles

26

Connect distal parts of the same hemisphere

Long fibers of the association axon bundles
