Neurotransmitters
21. These are produced by the pituitary gland and the
hypothalamus in vertebrates during exercise, excitement, pain,
consumption of spicy food. Also known as ENDOGENOUS
OPIATES they contribute to the feeling of well-being and act
similarly to opiates. They are also known to reduce pain and
anxiety.
Acetylcholine
Dopamine
Serotonin
Gamma Aminobutyric Acid (GABA)
Glutamate
Endorphins
Epinephrine and Norepinephrine
Neurotransmitters
22. This is a neurotransmitter in both the peripheral nervous
system, where it activates the muscles, and the central nervous
system, where it acts as a neuromodulator upon plasticity, arousal
and reward. It is one of many neurotransmitters in the autonomic
nervous system and the only neurotransmitter used in the motor
division of the somatic nervous system.
Acetylcholine
Dopamine
Serotonin
Gamma Aminobutyric Acid (GABA)
Glutamate

Epinephrine and Norepinephrine
Neurotransmitters
23. This is a protein that in humans is encoded by the GABRA1
gene. It acts at inhibitory synapses in the brain by binding to
specific transmembrane receptors in the plasma membrane of both
pre and postsynaptic neuronal processes. The primary role of this
neurotransmitter is to slow down the neuron activity.
Acetylcholine
Dopamine

Gamma Aminobutyric Acid (GABA)
Glutamate
Endorphins
Epinephrine and Norepinephrine
Neurotransmitters
24. This is a monoamine neurotransmitter, usually found in the
gastrointestinal tract, platelets and the central nervous system. This
chemical is also known as the “happiness hormone”, because it
arouses feelings of pleasure and well-being. Low levels of
serotonin are associated with increased carbohydrate cravings,
depression, sleep deprivations and hypersensitivity to pain.

Dopamine
Serotonin

Neurotransmitters
25. This neurotransmitter is produced in quite a few areas of the brain,
including the substantia nigra and the ventral tegmental area. It is also a
neurohormone released by the hypothalamus. Its principle hormonal role
is to inhibit the release of prolactin from the anterior lobe of the pituitary.
Dopamine has important roles in behavior and cognition, voluntary
movement, motivation, punishment and reward, sleep, mood, attention,
working memory and learning.

26. This is the most abundant excitatory neurotransmitter in the
vertebrate nervous system. It is also the major excitatory
transmitter in the brain, and major mediator of excitatory signals in
the mammalian central nervous system, involved in most aspects of
normal brain functions including cognition, memory and learning.
It also tastes like chicken soup
