NDB: project to olfactory bulb
NBM: project to neocortex
DTN and PPN projects to
Rest of the brain
What is the third eye?
Habenula
Name the enzyme require for biosynthesis and degeradation of ACh?
ChAT and AchE
Write the ACh biosynthesis and degradation
Acetyl coA + choline —– using ChAT ——ACh + CoA
ACh—-using AChE—— acetate + choline
Name the anti cholinesterase that are organi phosphate that are irreversable:
Sarin
DDT
Name the anticholinestrase that are long acting?
Diazinon
Malthion
Name the AchE regenator:
Abidoxine

Donepezil
Physostigmine
Name the excitiory ACh R and their effector system:
M1, 3,5
Gq
Name the inhibitory mAchR an their effector system?
M1,4
Gi
Gi inhibit:
AC which inhibit the PKA through cAMP
Gq activate the
PLC which activate the PkC through production of GAD and IP3
M1 and 3 will block :
HVA through Gq
Explain the smooth muscle contraction via m3 :
Slow depolarization via Gq beta gamma subunit
Extremely slow IPSP through —— and ——- are inactivated by Gi mediated ———
M2 , GIRKs. Beta gamma
Anti-AchE block—– block via —–useful for alzimer, which enhance the memory , ligand useful is —–
Slow AHP , m1,5 , dianapezil
