The Brain Flashcards
VENTRICLES
make sure the brain stays afloat and cushioned like a pillow.
Hydrocephalus
-½ in 1000 children will get this in the U.S.
-Shunts can be used but 50% success rate
Swelling of head
Surgery will be required
-When correctly diagnosed and treated, the patient often can return to full functioning!
CSF
Waste removal
spread through ependymal cells
Marfan Syndrome
Stretchy skin ( hard to stich a patient do to the weak skin)
Abdominal pain.
Arms, legs, fingers, and toes that are much longer in relation to the rest of the body.
Chest that caves in or sticks out.
Curvature of the spine.
Flat feet.
Headaches.
Heartbeat that feels like it is skipping a beat, fluttering, or beating too hard or too fast.
Intracranial hypertension
Elevated CSF pressure can cause two problems, severe headache and visual loss. If the elevated CSF pressure remains untreated, permanent visual loss or blindness may result
Headaches.
Tinnitus (ringing in the ears)
Temporary blindness.
Double vision.
Blind spots.
Neck and shoulder pain.
Peripheral (side) vision loss.
Ehlers-Danlos syndromes (EDS)
joint hypermobility.
loose, unstable joints that dislocate easily.
joint pain and clicking joints.
extreme tiredness (fatigue)
skin that bruises easily.
digestive problems, such as heartburn and constipation.
dizziness and an increased heart rate after standing up.
BBB
Tight regulation for the movement of ions, molecules, and cells between the blood and the brain
MATERIALS TO AFFECT THE BBB
Lead
Mercury
Aluminum
CAROTID BLOOD SUPPLY
-Hits the brain and eyes
-Extreme rotation would lead to carotid dissection
Ischemic stroke
obstruction of a blood vessel by blood clot or lipid deposit
Hemorrhagic stroke
rupture of a cerebral or subarachnoid blood vessel
Frontal:
Schedule, imagine the future, or use reasoned arguments
Motor
execute voluntary movement, or intentional movement. i.e. kicking a ball
Somatosensory
Process Information about temperature, taste, touch, and movement from the rest of the body
Parietal
Reading and arithmetic but taste, aroma, and texture are part of it.
Temporal
Responsible for information for the ears. Underside (insula) of each temporal lobe plays a crucial role in forming and retrieving memories. Integration of memories, sensations of taste, sound, sight, and touch
Occipital
process of images from the eyes and link that information with images stored in memory
Wernick’s area
Sensory matching, junction of Parietal, Occipital, and Temporal lobe. Comprehension of speech
Broca’s area
Formulation of speech (sensory) which then passes to motor
Limbic system
Regulation of emotions and memories, learning and sexual stimulation.
BRAIN STEM
Midbrain
Pons
Medulla Oblongata
MIDBRAIN
If damaged then Parkinsons
PONS
Relays and regulates the signals that give you the sensation of pain from anywhere in your body below your neck
Connection point to your cerebellum
Coordination and movement
CN 5-8
CEREBRUM
White matter
Majority
Myelinated fibers for transmission
