PSYC 202 Study Guide - Midterm Guide: Mesonephric Duct, Y Chromosome, Wilder Penfield
Document Summary
Neural and hormonal communication work together to coordinate behavior. Oxytocin is released into these blood vessels and it travels down the bloodstream and affects cells with oxytocin receptors. Evaluate this statement by discussing the experimental evidence discussed in class. Clearly explain the experimental manipulation and behavioral outcome. In male rats, the default is androgen exposure after the first six weeks as an embryo, while in female rats, there are no androgens or estrogens present. The presence of sex hormones masculinizes the rat: sry protein provided on the y chromosome allows for the development of testes, which stimulate production of testosterone (allow wolffian ducts to form) and amh (anti-mullerian hormone). Absence of both hormones leads to the feminization of internal reproductive structures. Project to paraventricular nucleus in hypo, inhibit cell bodies by binding to their specific receptors to increase appetite. Project to lh and agouti-peptide acts as competitive inhibitors with alpha.
