central canal is
החלק התחתון של ה medulla
the coroid plexus :
CSF source in the ventricals of the brain and it is in the center of the lateral and up of the third ,and in the fourth ventrical
coroid plexus is made of :
pia and epindema
basal nuclei contains:
corpus striatum (striatum ,lentiform) , STN,substantia Nigra
what is the function of basal nuclei
מאפשרים לנו לבצע פעולות מתוכננות ומתואמות (איזון)
VA , VL are inhibitory / excatory
excatory מפעיל את הקורטקס המוטורי
מדכאי התלמוס
GPi , SNr
if striatum is working then what happens to the cortex
הסטריאטום מדכא את מדכאי התלמוס שמפעיל את הקורטקס המוטורי - direct way
indirect way of motor systems
other neurons in the striatum are working –> shut down the GPe –> the STN works –>makes GRi work –>shuts down the thalamus –> the motor cortex doesnot work
Is STN involved in direct/indirect way
indirect
does dopamin uplifts or downwards the motion ?
both in direct and indirect dopamin uplifts motion
what receptor in direct way affects striatum
D1
what receptor in indirect way affects striatum
D2
is there choroid pelxus in the third ventricle
yes
