The diencephalon is a blanket name. What 4 large structures are the main feature of this area?

THALMIC REGION
Epithalamus
Thalamus
Hypothalamus
Subthalamus

2

What are the 3 structures of the epithalamus?

Stria medullarius
Habenula
Pineal gland (darker an sits behind/above posterior commissure)

3

You should be able to identify/name 9 thalamic nuclei. GO!

1. Anterior nucleus
Medial region:
2. Centromedian
Ventral:
3. Pulvinar
4. Lateral geniculate
5. Medial geniculate
