delirium

transient acute confusional state with hyperexcitabillity

chorea = Sydenham = St. Vit dance

sudden, jerky, involuntary, purposeless movement. Usually head and neck + hands

boyancy - one of functions of CSF

making the brain float in CSF. Reducing its effective weight from 1400g to 47g.

turbid CSF

mętny PMR

hydrocephalus

excessive fluid in the cranial cavity

cysterns (cerebello-medullary/cerebello-pontine)

expanded areas where lot of CSF Is present

synapse – synaptic cleft (=gap)

meeting point of membrane of two cells where the information is transferred from one cell to another

neurotransmitters: acetylcholine, dopamine, noradrenaline, endorphins

specifical chemical substances that are present in the nerve endings and there are released from one nerve ending to transfer the signal to the postsynaptic membrane

excitible cells

those cells that when stimulated properly can generate AP wave of depolarization and repolarisation
