Anterior pituitary stains darker and posterior pituitary stains lighter - Correct Answer Which portion stains darker? Which portion stains lighter? Anterior is composed of epithelial tissue Posterior is composted of nervous tissue - Correct Answer What type of tissue is composed in the anterior pituitary ? Posterior pituitary ? The hypothalamus produces BOTH releasing and inhibiting hormones that influence the anterior pituitary to secrete hormones via the hypophyseal portal system - Correct Answer How does the hypothalamus communicate with the anterior pituitary ? The hypothalamus produces oxytocin and vasopressin or ADH - antidiuretic hormone for the posterior pituitary to secrete , action potentials spread along axons of neurons from the hypothalamus into the posterior pituitary where those 2 hormones are secreted - Correct Answer How does the hypothalamus communicate with the posterior pituitary ? FSH LH ACTH GH Prolactin TSH - Correct Answer What hormones are produced by the anterior pituitary? Oxytocin and vasopressin or ADH (antidiuretic hormone ) - Correct Answer What hormones are produced by the posterior pituitary ? TSH - stimulates the thyroid gland to produce thyroid hormones which regulate the body's metabolism - Correct Answer What effect does TSH have on the body? Prolactin stimulates breast milk producition after childbirth - Correct Answer What effect does Prolactin have on the body?

It regulates metabolism , heart and digestive functions - Correct Answer What are the effects of thyroxine on the human body ? It produces calcium and phosphate from the parafollicular cells in the thyroid - Correct Answer What are the effects of calcitonin on the human body? The parathyroid and thyroid - Correct Answer What structure is this? anterior pituitary - Correct Answer B posterior pituitary - Correct Answer A thyroid - Correct Answer follicular cells - Correct Answer Responsible for the production and secretion of T3 & T4 (thyroxine) parafollicular cells - Correct Answer Secrete calcitonin colloid - Correct Answer
