Question 1

Association Fibers (not in CNS review lecture)

Answer 1

Fasiculi

Question 2

Commisural Fibers (not in CNS review lecture)

Answer 2

Corpus Callosum (Rostrum, Genu, Body, Splenium)

Question 3

Internal Capsule (Subcortical white matter)

Answer 3

Projection Fibers; composed of myelinated axons and oligodendrocytes (located between lenticular nucleus and head of caudate and the thalamus)

Question 4

Basal Ganglia

Answer 4

1. Striatum- caudate, putamen
2. Globus Pallidus- internal segment, external segment
3. includes structures of diencephalon (subthalamic nuclei) and midbrain (SN pars reticulata and compacta)

Question 5

Hippocampus

Answer 5

internal to parahippocampal gyrus (temporal cortex); composed of horizontal layers of neuron cell bodies

Question 6

Thalamus (part of diencephalon)

Answer 6

ovoid nuclear mass, superior to hpothalamic sulcus between interventricular foramen and splenium of corpus collasum

Question 7

Hypothalamus (part of diencephalon)

Answer 7

aggregations of neuron cell bodies and axons; inferior to hypothalamic sulcus, superior to pituitary gland and caudal to lamina terminalis

Question 8

Epithalamus (not in CNS review lecture)

Answer 8

pineal gland (external)

Question 9

Amygdaloid

Answer 9

Internal to uncus of temporal cortex, rostral to hippocampus, composed of aggregation of neuron cell bodies
