LAB #3. THE ENDOCRINE SYSTEM 1 | Page STATION 1. HISTOLOGICAL EXAMINATION OF ENDOCRINE TISSUES Relevant Textbook Readings: Ch16 Fig16.8 , Fig 16.13, Fig 16.17, Ch27 Fig 27.3, Fig 27.18. OBJECTIVES 1. To examine histological sections of different endocrine tissues. 2. To describe structural and functional differences among endocrine tissues. 3. To identify endocrine tissues/glands from their histological sections. HISTOLOGY OF ENDOCRINE TISSUE At this station, you are asked to view the various types of endocrine tissues under your microscope and to draw what you see in the field of view. The goal of this exercise is to help you identify key differences in the histological appearance of the various endocrine tissues. With your TA, ensure that you can identify the hormones produced by these tissues and their primary functions. ENDOCRINE TISSUE HISTOLOGICAL DRAWING HORMONES & FUNCTION Pituitary HORMONES OF ANTERIOR LOBE TSH - ACTH - FSH - LH - PRL - GH - Also MSH- stimulates melanin production and suppress appetite HORMONES OF POSTERIOR LOBE ADH - Oxytocin -

LAB #3. THE ENDOCRINE SYSTEM 2 | Page Thyroid HORMONE: _________________ 1)increase heart rate and contractile force= BP 2)increase sympathetic stimulation sensitivity 3)increase oxygen and energy consumption 4)stimulates red blood cell formation formation to enhance oxygen delivery HORMONE: _________________ Decreases calcium ion concentrations in blood by inhibiting osteoclasts resorption of bone Adrenal HORMONES OF THE CORTEX HORMONE: __________________ Increase renal reabsorption of sodium and water and accelerates urinary loss of potassium HORMONE: __________________ Releases amino acids from skeletal muscles, lipids from adipose tissue and promotes glycogen breakdown in the liver. Enhances vasoconstriction and has anti inflammatory effects HORMONE: __________________ Uncertain significance in normal conditions; May participate in pubertal development and sex drive in females. HORMONES OF THE MEDULLA HORMONE: __________________ Increases cardiac activity, glycogen breakdown in liver and blood glucose levels. Simulates release of lipids by adipose tissue and promotes peripheral vasoconstriction to increased blood pressure.

LAB #3. THE ENDOCRINE SYSTEM 3 | Page Pancreas HORMONE: __________________ Increases blood glucose by: Glycogen breakdown into glucose Gluconeogenesis - synthesis of glucose from lactic acid and other noncarbohydrate molecules Simulates glucose release into blood by liver cells Decreases amino acid concentration in blood in order for liver to make more glucose HORMONE: __________________ Lowers blood glucose by: Enhances membrane transport of glucose into cells Inhibits breakdown of glycogen to glucose Inhibits amino acid and fat conversion into glucose
