The Compass of Pleasure 2 Flashcards
uptake
an act or instance of absorbing and incorporating something especially into a living organism, tissue, or cell.
serotonin
a compound present in platelets and serum that constricts the blood vessels and acts as a neurotransmitter.
partially responsible for feelings of satiation.
ex. eating cake - with continued activiation of reward center dopamine goes up and serotonin goes down
axon
the appendage of the neuron that transmits impulses away from the cell body.
cell body
is the spherical part of the neuron that contains the nucleus. The cell body connects to the dendrites, which bring information to the neuron, and the axon, which sends information to other neurons.
dendrites
the spiky projections from the cell body that receive signals from other neurons.
platelet
a minute colorless disklike body of mammalian blood that assists in blood clotting by adhering to other platelets and to damaged epithelium.
MD - PLATE -disklike
tissue

hippocampus
responsible for the formation of memories
ex. Eating Cake - Let me remember everything about this environment so we can do this again. What restaurant I’m at, what piece I had.

vesicle
a small fluid-filled bladder, sac, cyst, or vacuole within the body.
”..Dopamine is packed into membrane-bound vesicles in the presynaptic (information-transmitting) neuron…” (17)
dopamine transporter
is a membrane-spanning protein that pumps the neurotransmitter dopamine out of the synapse back into the axon of the transmitting neuron.
“Dopamine released into the cleft can bind dopamine receptors on the dendrite of the postsynaptic (information-receiving)neuron, thereby exerting its effects, or undergo reuptake into the axon terminal through a dopamine transporter, where it will be recycled for later use.” (17)
