external triggers
Central to detecting threats abs triggering fear responses - CORRECT ANSWER
Amygdala
Regulates emotional responses and helps suppress inappropriate fear - CORRECT
ANSWER prefrontal cortex
Involved in memory processing and distinguishing between real threats and
perceived ones - CORRECT ANSWER Hippocampus
Activates the autonomic nervous system, leading to psychological fear responses -
CORRECT ANSWER Hypothalamus
Region of midbrain that plays an important role in perception of pain; activates
descending neural pathway that uses serotonin to close the "pain gate" - CORRECT
ANSWER periaqueductal gray (PAG)
Coordinates defensive responses like freezing or fleeting - CORRECT ANSWER
periaqueductal gray
,A neurotransmitter that enables learning and memory and also triggers muscle
contraction - CORRECT ANSWER Acetylcholine
helps control alertness and arousal; undersupply can depress mood - CORRECT
ANSWER Norepinephrine
a neurotransmitter that regulates motor behavior, motivation, pleasure, and
emotional arousal - CORRECT ANSWER Dopamine
Affects mood, hunger, sleep, and arousal
Regulates mood and sleep-wake cycle - CORRECT ANSWER Serotonin
Promotes wakefulness and promotes sleep - CORRECT ANSWER Histamine
Synthesized from histidine by by histidine decarboxylase in mast cells, basophils.
And hypothalamus - CORRECT ANSWER Histamine
Produces orexin (hypocretin) - CORRECT ANSWER Lateral hypertrophy thalamus
A sleep disorder characterized by uncontrollable sleep attacks. The sufferer may
lapse directly into REM sleep, often at inopportune times.
