In terms of the chemical structure there are amino acid hormones (e.g. thyroid products), peptide hormones (e.g. vasopressin) and steroid hormones (e.g. cortisol*). HYPERPOLARIZATION – A change in the membrane potential to a value more negative than the value of a resting potential. HYPOTHALAMUS – A complex brain structure which consists of many nuclei and performs various functions. It regulates the activity of internal organs, monitors autonomic system and controls the pituitary gland. IMMUNE SYSTEM – Various tissues, cells and their products responsible for protecting the organism against harmful bacteria, viruses and parasites. INHIBITION – In general: reducing, blocking enzyme/receptor activity. In reference to the neurone, it is a synaptic event which stops the receiving neurone from firing. IONS – Electrically charged atoms or molecules. LIMBIC SYSTEM – A group of brain structures, which includes the amygdala*,
management of the damaging stress response. 1.3 Stress and physiological factors. Organisms respond to stress with secretion of neuroendocrine mediators. These hormones interact with physical, cognitive and emotional processes. (Steptoe et al., 2007; Herbert et al., 2006; De Kloet et al., 2005; Kiecolt-Glaser et al., 2003; Rohleder et al., 2002,). Psychological and other forms of stress influence the sympathetic nervous system, hypothalamuspituitary adrenal (HPA) - axis, and immune system; the interaction between these systems is complex (Raison et al., 2003, Pariante & Miller, 2001; Adler, Felten & Cohen, 2001). Activation of the HPA axis by physical or psychological stress begins with corticotrophin-releasing hormone (CRH) secretion from the Hypothalamus, CRH then signals the Anterior Pituitary gland to secrete Adrenocorticotropic hormone (ACTH), ACTH then acts on the Adrenal gland which

neurotransmitter serotonin in the brain. People with depression are often treated with SSRI-s, that block serotonin reuptake when it is in the synapse, causing it to act for a longer time than normal and increasing the available serotonin that is needed for mood regulation. Using one or more examples, explain functions of two hormones in human behavior. Oxytocin is a hormone that is produced by the hypothalamus after being stimulated by the pituitary gland. It is released with touches and hugs. Oxytocin is associated with bonding between a mother and a child and as well as between lovers. If oxytocin is given to healthy individuals, it seems that their brain circuits involved in fear are affected and there is an increase in trust and generosity. The production of melatonin by the pineal gland is stimulated by darkness and inhibited by light. Melatonin levels peak in the middle of the night and decrease towards the morning
