3. • Endocrine glands release their secretions – hormones – directly into the bloodstream, from
where they are distributed to target cells (tissues)
• Recall that neurotransmitters like adrenaline and noradrenaline can also be hormones!
9. Oxytocin
• Best known for its role in lactation and
uterine-contraction properties during birth
But!
The “bonding hormone”, “facilitator of life”
• “Oxt is important for social memory and attachment, sexual and
maternal behavior, and aggression. Recent work implicates Oxt in
human bonding and trust as well. Human disorders characterized by
aberrant social interactions, such as autism and schizophrenia, may
also involve Oxt expression. Many, if not most, of Oxt’s functions,
from social interactions (affiliation, aggression) and sexual behavior
to eventual parturition, lactation and maternal behavior, may be
viewed as specifically facilitating”
