|
Fourth ventricle |
Ventricle where CSF comes out to the subarchnoid space |
|
Basal nuclei |
Huntingtons disease and parkinsons disease affect this part of the brain |
|
Corpus callosum |
Huge bundle of axons connects the left and right hemispheres, harder than any other brain tissue, calloused body |
|
Third ventricle in the thalamus |
This part sits on top of the brain stem and directs sensory impulses up to the conscious part of the brain. Decides what sensations we will notice |
|
Longitudinal fissure |
The deep groove |
|
Link between hemispheres |
Corpus callosum |
|
Hole with CSF |
Lateral ventricle |
|
Thin hole with CSF |
Third ventricle |
|
Parkinsons disease |
Muscles stay contracted, causing rigidity, stiff face, trembling hands, and hunger L-dopa is main treatment Disease starts when the substantial nigga stops making dopamine |
|
Huntingtons disease |
Totally genetic, risk for kids 50% if parent has it More severe than parkinsons Basal nuclei disintegrates, dopamine levels are normal |
|
Flow of CSF |
1. CSF comes out of choroid plexuses in the lateral ventricles. 2. Third ventricle in thalamus. 3. Cerebral Aqueduct in the midbrain. 4. Fourth ventricle under the. cerebellum. 5. Subarchnoid space around brain and cord. 6. Into the blood in a dual sinus. |
|
Hydrocephalus |
When CSF accumulates in the ventricles |
|
Migraine Pains |
Cerebral arteries by constricting and dilating too much. |
|
Spinal Tap/ Lumbar Puncture |
To pull out CSF to see if meningitis is viral or bacterial, causes spinal headaches until CSF is able to float back to brain. Bacterial = deadly |
|
Epidural |
Injection of anesthetic into fat filled epidural space, no headache |
|
Spinal anesthesia |
Injection of anesthetic into the subarchnoid space, causes headaches because CSF may leak out of meninges after surgery. Most dangerous because needle is so close to cord. |
|
Epidural bleed |
Arterial bleed |
|
Subarchnoid bleed |
Arterial bleed |
|
Subdural bleed |
Bleeding veins and most lethal head bleed |
|
Blood Brain Barrier |

|
Why do we sleep? |
Increased CSF flow during sleep washes out metabolic wastes. |
