Answer:
The delta waves seen in the EEG when someone is in stage 3 sleep can be likened to:
B) the slow movement of "the wave" around a stadium.
Explanation:
Delta waves are a type of brain wave found in humans. It is a slow, low-frequency brainwave (between 1.5 and 4 hertz) that has high amplitude. The best way to imagine it is to compare it to "the wave" done by people around a stadium. That slow yet ample movement of "the wave" helps us visualize what the delta waves seen in the EEG are like. Delta waves are associated with deep sleep - the third and fourth stages of sleep.
Answer:
Night terrors
Explanation:
A child having night terrors can not be easily consoled, he or she will fall back to sleep afterward, and will find no memory of the night terror in the morning when he or she wakes up.
Night terrors can be triggered by various underlying reasons that hinder sleep. These includes:
1. Sleep-disordered breathing.
2. Mood disorders.
In the question above, night terrors are characterized by a sudden arousal from sleep and intense fear, usually accompanied by several physiological reactions such as rapid heart rate and breathing, screams, heavy perspiration, and physical movement.
Answer:
Stressors stimulate the release of <u>adrenocorticotropic hormone</u> from anterior pituitary which then stimulates the secretion of <u>cortisol</u> from adrenal cortex.
Explanation:
Stress can be described as the response of an organism to an environmental condition or event or external stimulus which causes stress.
The major systems that respond to stress are autonomic nervous system and hypothalamic-pituitary-adrenal axis (HPA axis).
The HPA axis is responsible for releasing vasopressin and corticotropin releasing hormone from hypothalamus which stimulates the anterior pituitary to secrete adrenocorticotropic hormone. The adrenocorticotropic hormone the stimulates the secretion of cortisol from adrenal cortex of the adrenal gland.
Answer:
World War II profoundly affected the pioneer powers since it totally decimated their economies. Despite the fact that Hitler carried out wrongdoings against humankind, I give him credit—and not Gandhi—for India's freedom following World War II
