CHAPTER 3: MACROSCOPIC BASIS OF NEUROANATOMY (Interbrain, Basal Ganglia, & Limbic System)

 

 

Interbrain (Diencephalon)

 

·        Contains the 3^rd ventricle

 

4 Divisions:

1.      Epithalamus

a.       Habenula

b.      Stria medullaris

c.       Pineal gland (epiphysis)

2.      Thalamus

a.       Medial Geniculate Nucleus/Body

b.      Lateral Geniculate Nucleus/Body

c.       Ventral Postero-Lateral Nucleus (VPL)

d.      Ventral Postero-Medial Nucleus (VPM)

3.      Hypothalamus

a.       Hypothalamic Nucleus

4.      Subthalamus

a.       Subthalamic Nucleus

b.      Zona Incerta

 

·        Medial and Lateral Geniculate Nuclei, together, are called Metathalamus

·        Epicritic/Discriminative Sensibility (Discriminatory/Fine Touch)

·        Stereognosis/Stereognosia

·        Astereognosis/Astereognosia

·        Somaesthetic area

 

 

Basal Ganglia

 

1.      Caudate

a.       Medial Caudate

b.      Nucleus Accumbens

2.      Putamen

3.      Substancia Nigra

a.       Substancia Nigra Pars Compacta (SNpc)

b.      Substancia Nigra Pars Reticula (SNpr)

4.      Globus Pallidus

a.       Globus Pallidus Externa (GPe)

b.      Globus Pallidus Interna (GPi)

 

·        Striatum

·        Corpus Striatum

·        Lenticular Nucleus

 

 

Limbic System

 

1.      Hypothalamus

2.      Hippocampus

3.      Amygdala

 

·        Septum

·        Ventral Tegmentum Area

·        Prefrontal Cortex
