Document Summary
Hypothalamus communicates with the pituitary: hypothalamus releases releasing hormones that travel down the tract to either posterior or. October 24, 2016 anterior part of the pituitary: the pituitary is similar to a middle-man and releases hormones that affect the organ. Osmoreceptors in the hypothalamus detects osmolarity: hypoosmtoic low sodium; want to retain sodium; release antidiuretic hormone (adh/vasopressin) Stimulates the posterior pituitary releases adh retains water collecting. Posterior pituitary is responsible for duct is more permeable to water: oxytocin, which is responsible for letdown of the milk from mammary glands and ducts, contraction and relaxation of the uterus. Anterior pituitary is responsible for : growth hormones affects bone and tissue formation, follicular stimulating hormone (fsh) and luteinizing hormone (lh) Affects the testes and ovaries: prolactin synthesizing the milk in the breast, thyroid stimulating hormone (tsh) Results in the thyroid releasing thyroid hormones. Some organs release another signaling mechanism: hypothalamus pituitary tsh thyroid gland thyroid hormones, 3-4 step process.
