Week 2: Station 3 - Transverse Sections of the Brain Flashcards
Where is the internal capsule?
What structures constitute the basal ganglia?
Caudate nucleus
Lentiform nucleus
What is the internal capsule made of and what type of fibres?
White matter
- Projection fibres
What is the function of the substantia nigra?
- Dopaminergic
- Input of dopamine in the basal ganglia
Is the red nucleus anterior or posterior to the substantia nigra?
Posterior
What fibres are found in the cerebral peduncles?
Projection
To identify what section is from where look for specific parts. For the midbrain, look for A
For the pons look for B
For the medulla look for C
A) Substantia nigra, red nucleus and colliculi
B) Middle cerebellar peduncle
C) Ducussation of the CST at pyramids, olivary bodies
What fibres make up the olive and the pyramid?
Motor fibres
