PSYCH 15 Lecture Notes - Lecture 17: Lesion, Bisexuality, Synaptogenesis
Document Summary
Developmental (or organizational): influencing development of anatomical, physiological, and behavioral characteristics that differentiate the sexes. Activational: triggering reproduction related behavior in mature individuals. Adolescent surges have both developmental and activational effects. Exocrine: release chemicals into ducts which carry them to their targets. Endocrine: ductless; release hormones directly into circulatory system. Only organs whose primary function is hormone release are referred to as endocrine glands. Short and long chains of amino acids. Fat-soluble: able to enter cells and bind to receptors in cytoplasm or nucelus. Adult testes release more androgens and ovaries more estrogens. Progesterone prepares uterus and breasts for pregnancy. Adrenal cortex: also releases small amounts of sex steroids. Posterior pituitary: hormones synthesized in the hypothalamus. Tropic hormones influence the release of hormones by other glands. Female hormones go through a 28 day cycle, the menstrual cycle. Anterior pituitary activity is controlled by the hypothalamus. Synthesized in hypothalamic paraventricular and supraoptic nuclei. These nuclei have terminals in the posterior pituitary.
