Week 3 (The Brain) Flashcards
The Central Nervous System
Brain: Complex behaviours and experiences
Spinal Cord: Reflexes
Brain Matter
Gray Matter: Nerve cell bodies
White Matter: Nerve cell tails (axons)
Gray on outside, White on inside.
Cortex
Outer surface of the brain
Brain directions
Front: Anterior/ Rostal
Back: Posterior/ Caudal
Top: Dorsal/ Superior
Bottom: Ventral/ Inferior

Brain protection
Ventricles are filled with cerebrospinal-spinal fluid
Layers of protection: Skull, Dura Mater, Arachnoid membrane, Pia Mater.
