2 Flashcards
Emotion has two major components:
1)_____ such as a rapid heartbeat, and
2) ____: a conscious, subjective experience or feeling, such as feeling scared
Physical sensation
Physiological
Movement of the human face is controlled by two cranial nerves, ______and the _____
the facial nerve (cranial nerve VII)
trigeminal nerve (cranial nerve V).
controls the superficial muscles attached to the skin, which are primarily responsible for facial expressions.
The facial nerve (CN-VII)
controls the deeper facial muscles attached to the bones of the head that are responsible for chewing food and speaking.
The trigeminal nerve (CN-V)
People with damage to the ______, are unable to smile on command on the side of the mouth contralateral to their damage.
primary motor cortex
People with damage to the primary motor cortex, are unable to smile on command on the side of the mouth contralateral to their damage. But when they hear a good joke, they can show some spontaneous smiling on the otherwise paralyzed side of the face. This condition is known as ______
volitional (voluntary) facial paralysis
people with Parkinson’s disease, which involves subcortical motor structures including the substantia nigra and basal ganglia lose the ability to smile spontaneously while retaining the ability to smile on command only. This condition is referred to as______because the ability to express spontaneous emotions is impaired, thus it looks like their emotion is flat affect!
emotional facial paresis
The ______,____, and ____ all interact to assist the body in experiencing and processing emotions.
limbic system, autonomic nervous system, and reticular activating system
The___is the area of the brain most heavily implicated in emotion and memory. Its structures include the hypothalamus, thalamus, amygdala, and hippocampus.
limbic system
plays a role in the activation of the sympathetic nervous system,
hypothalamus
serves as a sensory relay center; its neurons project signals to both the amygdala and the higher cortical regions for further processing.
thalamus
plays a role in processing emotional information and sending that information to cortical structures
has received a great deal of attention from researchers investigating the biological basis of emotions, particularly of fear and anxiety & aggression among children or adolescents
amygdala
integrates emotional experience with cognition
As with the amygdala, research has demonstrated that_____ and function are linked to a variety of mood and anxiety disorders.
hippocampus
Individuals suffering from ______show marked reductions in volume in several parts of the _____, which may be the result of decreased levels of neurogenesis and dendritic branching
post-traumatic stress disorder (PTSD)
hippocampus
The______is part of the peripheral nervous system in humans. It is regulated by the hypothalamus and controls our internal organs and glands, including such processes as pulse, blood pressure, breathing, and arousal in response to emotional circumstances.
autonomic nervous system(ANS)
