• There are four main types of mood reactions:

(1) Physical reactions: When a person or animal experiences an external threat or challenge, respond immediately to deal with the situation! Therefore the need for extra power arises.

• The autonomic nervous system becomes active to deal with this situation.
• In 1920, Walter Kane scientifically described the entire human process, stating that the body's cells are activated to meet the challenge or threat that activates the endocrine glands.
• Kane has called this reaction a fight or a runaway reaction.
• The hypothalamus of the brain is the origin of the physical response to depression. Which is also known as the center of mind. The hypothalamus responds to such a situation in two main ways.
• (1) by the autonomic nervous system (2) by activating the brain gland. The autonomic nervous system has two parts (a) sympathetic system and (b) parasympathetic system.
• As the sympathetic system becomes active, deep breathing becomes faster, heart rate increases, blood vessels constrict, and blood pressure rises.
• Changes in the muscles of the throat and nose cause more air to reach the lungs. Facial expressions also change according to impulse.
• The secretion of corticosteroids into the bloodstream by the adrenal glands is disrupted.
• Through which energy is transmitted to the body.
• The secretions from the cerebellum stimulate the larynx and adrenal glands, which cause a number of changes.
• As more blood cells are released so that the blood freezes faster, more white blood cells are produced from the bone cavity.
• The liver produces more sugars which are needed for more physical activity.
