Study Notes
Parkinson's Disease
- Damage to neurons in the substantia nigra leads to decreased dopamine levels, causing Parkinson's Disease.
- Treatment involves replacing dopamine.
Brainstem
Pons
- Relays sensory information between the cerebellum (for balance) and cerebrum (conscious awareness).
Cerebral Aqueduct
- Connects the 3rd and 4th ventricles.
- Used CSF drains out of the brain and returns to blood circulation through the aqueduct.
Ventricles of the Brain
- 3rd ventricle
- Lateral ventricle
- Cerebral aqueduct
- 4th ventricle
- Fornix
- Mammillary body
CerebroSpinal Fluid (CSF)
- Derived from plasma.
- Similar to plasma.
Problems with Meninges
Hydrocephaly
- Accumulation of CSF inside the ventricles.
- Usually congenital, caused by a blockage of the cerebral aqueduct.
