Emotional Changes Emotional Changes Presentation Transcript

  • Physiological  behavioral  cognitive
  • The systems involved in change are following Autonomic Nervous System Glandular System especially adrenal gland Limbic System
  •  Most of the physiological change that take place during emotional arousal result from activation of the sympathetic division of the autonomic system, as it prepares the body for emergency action.
  •  In normal life, when we experience an intense emotion, such as fear or anger, we become aware of many bodily changes which include  rapid heartbeat and breathing,  dryness of the throat and mouth  , increased muscle tension, respiration, trembling of the extremities and a sinking feeling in the stomach.
  • Responsible for most of the physiological changes  ANS is the part of the peripheral nervous system that carries information between the brain and all organs of the body.  The ANS affects all of the organs such as the heart and blood vessels , the digestive system and so on.  The autonomic nervous system coordinates their functioning to meet the needs of the whole organism .  it prepares the body for changes by modulating the activity of the organism.  Automatic nervous system has two division Sympathetic Nervous System Parasympathetic Nervous System
  • prepares the organism for vigorous activity The sympathetic system is responsible for the following changes  Blood pressure and heart rate increase.  Respiration becomes more rapid.  The pupils dilate.  Perspiration increases while secretion of saliva and mucous decreases.  Blood sugar level increases to provide more energy.  In case of wound the blood clots more quickly. Blood is diverted from the stomach and intestines to the brain and skeletal muscles.  The hair on the skin becomes erect, causing "goose bumps". These reactions are called ‘’fight or flight’’ syndrome because they prepare the body to combat or run from a threatening situation
  •  The parasympathetic system which is actually energy conserving system, takes over and returns the organism to its normal state.  For example ,during anger , sympathetic nervous system increases the heart rate and the parasympathetic nervous system causes tears to flow in grief  In both the parasympathetic and sympathetic systems, there is relay station called a ganglion between the central nervous system and target organs.
  • also part of sympathetic nervous system adrenal gland has two parts adrenal cortex  adrenal medulla both of which participate in emotional responses
  • display of emotional reactions It consists of Amygdala Hippocampus Septum  amygdala is involved In emotional awareness and expressions ;it is also produces reaction of aggression when stimulated. Septum has the opposite effect. It reduces the intensity of emotional reactions when stimulated
