Chapter-08 Human Physiology: Co-ordination and Control. Chemical Co-ordination and Endocrine Glands Learning output After completing this lesson students should be able to… tell the definition of chemical co-ordination tell the location of different types of endocrine glands describe the functions of different of endocrine glands. Chemical Co-ordination A group of cells releases hormones which regulates the activities of others cells of the body is called chemical coordination . Pineal Pituitary Thyroid Parathyroid Thymus Adrenal Pancreas Ovary Testis Pituitary Gland 1. STH: Controls growth of tissue, bones, metabolic process and break down of glycogen. 2. TSH: Secretion of thyroxin and intake of iodine by the tissue. 3. ACTH: Regulates the adrenal gland and influence of melanocyte production. 4. LH: In male- testosterone, endrogene, in femaleprogesterone . 5. FSH: Producing and development of sperm and ovum. . 6.ADH: Increasing blood pressure, absorbing water by kidney. 7. Oxytocin : Contraction of uterus and regulates lactation. Thyroid Gland Thyroxin hormone: Increases the metabolism of iodine, protein and carbohydrates. Pituitary Gland Thyroid Gland and Parathyroid Gland Parathyroid Gland Parath or parathyroid hormone: Calcium releasing from bone, calcium absorbing from food and preventing calcium loss by urine. Team work Group-A Group-B Write down the location and functions of pituitary glands Write down the location of thyroid and parathyroid glands and their functions. Evaluation Having seen a dwarf man and patient of goiter Dr. Islam said to his friend , “ the abnormal activities of two special glands are responsible for the condition of two men.” a. What is gland? b. Why is the pituitary called the master gland ? c. Describe the function and structure of the mentioned gland concerned with the fist man. d. Analyze the statement of doctor.
