  Affects parent-infant bonding
• How does oxytocin influence animal behavior?

  Increases bonding and monogamous behaviors
• Where are the adrenal glands located?

  Above the kidneys
• What are the two parts of each adrenal gland?

  Adrenal cortex and adrenal medulla

  Cortisol
• What is the function of cortisol?

  Increases blood clotting and sugar levels
• What hormones are produced by the adrenal medulla?

  Adrenaline and noradrenaline
• What is the role of adrenaline and noradrenaline?

  Prepares the body for fight or flight

  • Major glands include pituitary, adrenal, and reproductive glands: True
  • Endocrine glands produce and release hormones: True
  • The Pituitary gland is controlled by the Hypothalamus: True
  • The Posterior Pituitary releases ACTH: False (Anterior releases ACTH)
  • The Anterior Pituitary releases hormones for reproductive functioning: False (Posterior releases Oxytocin)
