Psychobiology Flashcards
hormone found in the posterior pituitary gland conserves body water and maintains normal blood pressure.
ADH
called the “master gland”. It controls endocrine function and stores ADH and oxytocin
the pituitary gland
includes Norepinephrine, dopamine, serotonin, and histamine
Monoamines
controls mood, cognition, perception, locomotion, cardiovascular functioning, sleep and arousal.
too little-depression
too much-mania, anxiety, schizophrenia
Norepinephrine
controls movement and coordination, emotions, voluntary judgement, release of prolactin.
too little- Parkinson’s
too much-Mania and schizophrenia
Dopamine
sleep, arousal, libido,appetite, mood, aggression, pain perception, coordination,judgment
too little- depression
too much -anxiety
serotonin
Calming effect, slowdown of body activity
too little-Huntington’s disease, anxiety, schizophrenia, and various forms of epilepsy
GABA
modulation of pain, feel good hormones
endorphins
Cholinergic that functions in sleep, arousal, pain perception, movement, and memory.
too little- Alzheimer’s, Huntington’s disease, Parkinson’s
too much- depression
Acetylcholine
integrates all sensory input (except smell) on way to cortex, some involvement with emotions, and mood.
Thalamus
regulates anterior and posterior lobes of the pituitary gland; exerts control over actions of ANS, regulates appetite, and temperature.
hypothalamus
Responsible for visual, auditory, and balance(“righting”) reflexes.
Mesencephalon which is in the Midbrain
Regulation of respiration and skeletal muscle tone;
Pons
contains vital centers that regulate heart rate, blood pressure, and respiration; reflex center for swallowing, sneezing, coughing, and vomiting.
Medulla
regulates muscle tone and coordination and maintains posture and equilibrium
Cerebellum
