hormones.

• hormones - a01 explanation.

  hormones are released by the endocrine system and regulate many bodily processes such as breathing, stress and growth. they relay much slower than neurotransmitters and work longer. they work by binding to receptor proteins in target cells to change cell function to respond in a certain way. they can begin secretion as a result of other hormones or neural activity going on.

  adelson - electrically stimulated rats hypothalamus to cause a trigger of corticosterone, part of the aggression system. but when rats had their adrenal glands removed they were not aggressive and had little corticosterone. when injected however, it triggered an activation again
• hormones - evaluation.

  s - very scientific, testable and supported by studies. w - reductionist and only look at 2 hormones, usually always blaming testosterone when there are other hormones and factors too. biological explanations are correlational meaning it doesn't show cause + effect.
