(45 cards)
psychological and sociological stressors are perceived by the ____ and translated by the ____ which then instructs the rest of the ____ to adjust to the stressor
psychological and sociological stressors are perceived by the MIND and translated by the BRAIN which then instructs the rest of the BODY to adjust to stressor.
cerebral cortex (gray matter)
the upper part of the brain responsible for thinking functions - language and development
subcortex (which includes …)
the lower part of the brain responsible for various physiological processes necessary to stay alive
the cerebellum, medulla oblongata, pons, diencephalon)
cerebellum
part of the subcortex responsible for coordination
medulla oblongata
part of the subcortex responsible for the regulation of the heartbeat and breathing
pons
part of the subcortex responsible for regulating sleep
diencephalon
part of the subcortex responsible for regulation of the emotions
(includes the thalamus and hypothalamus)
thalamus
part of the diencephalon that relays sensory impulses to the cerebral cortex
hypothalamus
part of the diencephalon that activates the autonomic nervous system (and the endocrine system)
autonomic nervous system
controls such body processes as hormone balance, temperature, and width of blood vessels
limbic system (consists of …)
produces emotions; the seat of emotions
and behavioral expressions
thalamus and hypothalamus and diencephalon
reticular activating system (RAS)
a network of nerves that connects the mind and the body
endocrine system
comprised of hormones that regulate physiological functions
corticotropin releasing factor (CRF)
released by hypothalamus and results in the release of adrenocorticotropic hormone
adrenocorticotropic hormone (ACTH)
activates the adrenal cortex to secrete corticoid hormones
thyrotropic hormone releasing factor (TRF)
released by hypothalamus and stimulates the pituitary gland to secrete thyrotropic hormone
thyrotropic hormone (TTH)
stimulates the thyroid gland to secrete thyroxin
oxytocin
a hormone secreted by the pituitary gland
vasopressin (ADH)
a hormone secreted by the pituitary gland
hippocampus
the part of the brain that sounds the alarm that stress is present
adrenal cortex
the part of the adrenal gland that secretes corticoids (outer layer of adrenal glands)
glucocorticoids
regulates metabolism of glucose
mineralocorticoids
regulate the balance between sodium and potassium
cortisol
the primary glucocorticoid secreted from the adrenal cortex that is responsible for an increase in blood pressure
provides the fuel for battle (fight or flight)
