Acetylcholine

-choligeneric neuron


-Building blocks: Choline y Acetyl Enzyme A


-Acetyltransferase acts on these blocks and makes Ach.


-AcHe tears them down

Functions of Ach

-movement


-memory and learning


-Autonomic functions

Locations of Ach

-Basal Gangliar region


-neuromuscular junction

Subtypes of Choligeneric Receptors

-Nicotonic : Nicotine and Ach


-Muscaronic Muscarine and Ach

Monomines

-Catecholamines


-Indoleamines


-all subject to reuptake from synaptic gap

Catecholamines

-Dopamine


-Norepinephrine


-Epinephrine


-they share a common synthesis pathway

Dopamine

-Movement


-Reinforcement

-Found in any area dealing with life functions


-Pons, Medulla, Hypothalamus


Serotonin

-Sleep


-Appetite


-Mood


-Located in the pons, esp. the raphe nucleus.


Indoleamines

-Serotonin


-Melatonin

Functions: Excitation and Long-term memory


-Widely used in the CNS

GABA

-Major inhibitory NT of the CNS


-Synthesized by the enzyme made from glutamate.


-Inhibition


-Mood


-Seizure threshold

ATP

-Pain modulation


-Inhibition


-Located in the CNS, Autonomic Nervous system, and found in axons containing catecholmines.

Endorphins

-Pain reduction


-Feelings of pleasure


-Located all over the brain, hypothalamus, basal ganglia, spinal cord, etc.
