Amino a component of protein food.
ACTH (adrenocorticotropic ) : hormone secreted by the pituitary influencing the secretion cortisol.
Adrenaline: A hormone secreted by the adrenal medulla very important in the functioning of the nervous system and the body's response to various attacks (stress).
Amygdala: situated half in the right hemisphere and half in the left is the control center of emotions. If it is destroyed, it deletes any violence, fear, but also any emotional reaction; if it stimulates, the behavior becomes excessive, extremely violent or extremely affectionate sweetness.
Antidepressant: A drug that opposes the depression.
Anxiety: state of mental disorder caused by the feeling of an impending adverse event or dangerous.
Anxiolytic : A drug that reduces anxiety.
Axis catecholaminergic : axis that stimulates the creation of catecholamines (especially norepinephrine).
HPA Axis : axis that stimulates the creation of cortisol by the adrenal cortex .
Axone : constant extension of the neuron cell body.
C
Catecholamines : substance secreted by adrenal medulla, acting as a neurotransmitter.
Cingulum bundle of nerve fibers that allows communication between the various components of the limbic system .
corticotropin (TSH ) : hormone stimulated by hypoglycemia, trauma, emotions, and physical activity.
Cortisol : Main glucocorticoid hormone secreted by the adrenal cortex glands .
D
Dopamine: a neurotransmitter essential for normal brain activity, the precursor of norepinephrine.
dopaminergic name given to elements involved in the production of dopamine.
E
Enzyme: Enzymes are proteins present in cells of all living beings. Their function is to facilitate the chemical reactions that occur there naturally. For example, during digestion, are enzymes that accelerate the decomposition and transformation of food
G
gland medulla and adrenal gland : The adrenal glands are located above each kidney. They secrete hormones that help fight against stress.
Glucocorticoids : main substances secreted by cortex, acting as neurotransmitters.
H
Hormones: chemical developed by a group of cells or an organ, which exerts a specific action on another tissue or another body.
pituitary gland or pituitary : small gland about the size of a pea in the brain, very important, it secretes growth hormone and other hormones like ' ACTH.
Hypothalamus : main regulatory body of pituitary hormones.
I
Influx nervous : Series of events for the transmission of excitation in the nervous element.
M
monoamines : amine which does that a radical. Family composed of catecholamine neurotransmitters and indoleamine (serotonin).
N
nerve: cord that connects a central nervous (eg brain) to an organ or an organic structure and consists of many axons. Pain on the path of a nerve.
Neuron: nerve cell that includes a cell body (with nucleus) and extensions whose axons.
Neurotransmitter or neurotransmitter: a chemical that transmits nerve impulses from one neuron to another across the space between two consecutive neurons (synapses) and by binding to receptors specific situated the postsynaptic neuron .
Norepinephrine: neurotransmitter family catecholamines, a precursor of adrenaline.
noradrenergic : name given to elements involved in the production of norepinephrine.
R
Recapture : a phenomenon which is for neurons to recover presynaptic neurotransmitters released into the synapse.
S
Stress or general adaptation syndrome: report of a body in reacting to an agent of any assault (injury, injection, pain, joy, ...). Refers both to the action of the stressor and the reaction of the body.
Synapse : contact area of two neurons
T
Tryptophan : amino acid precursor of serotonin.
Tyrosine: amino acid precursor of dopamine, norepinephrine.
V
vasopressin : hormone secreted by the pituitary gland, which influences the secretion of ACTH .
Gall : body-shaped bag that serves as a reservoir (in this case, synaptic vesicles: tank neurotransmitters)
Z
Zone frontotemporal : brain area between the forehead and temples.
