Hormones and behaviour Flashcards
how are they released
Released by endocrine glands such as the adrenal glands, hypothalamus, pituitary glands, and pancreas. These glands form the endocrine system
Chemical messenger system of the organism
hormones
Chemicals which get secreted directly into the bloodstream where they get carried to all parts of the body
Important for emotional and motivational behaviour
Regulate slower processes like growth, metabolism, and digestion
Can only influence that have receptors for that particular hormone (target cells)
When a hormone binds to these cells, it launches a sequence of changes.
They do not influence behaviour directly, but they change the probability that a certain behaviour will occur in response to a certain environmental stimulus
Given the time it takes for circulation through the body, it can be weeks or months before the response occurs
Effects are much longer lasting than neurotransmitters
Oxytocin
Released by the pituitary gland
Known for its role in social interaction and sexual reproduction.
Plays a role in childbirth, stress reduction, trust, and social bonding
Released during breastfeeding
Role in establishing the bond between the mother and child
Released with every hug and associated with wider social emotions
Linked to trusting other people
Experimental manipulation of OT has shown an increase in trust
Trust is an important tool among humans
