Summary
Questions
L1: Neuroanatomy
LO:
The divisions of the nervous system
Anatomical planes and directions
The brain: grey and white matter
Protection of the brain (meninges, blood-brain barrier)
The ventricular system
The cortex: lobes, sulci, gyri
Primary and association areas
The Nervous System
CNS
Brain (encased in skull)
Spinal chord (encased in vertebral column)
PNS
Bio psych (1-5) 3
, Nerves
Motor pathways (info from muscles to CNS)
Sensory pathways (info from sensory systems to CNS)
The Brain
1. Cerebrum (meaning ‘brain’ in Latin)
2. Cerebellum
3. Brain stem
Two hemispheres, left and right
Contralateral (opposite side)
Ipsilateral (same side)
The brain receives a constant flow of blood (20% blood to heart) and oxygen
Deprivation = unconsciousness
Stroke = bleed/ blockage in brain resulting in dying brain cells (not enough
oxygen)
