 * =__//**HORMONES**//__=

1. Compare and Contrast the endocrine system and the nervous system. (At least three things) 2. What is a steroid hormone? How does it compare to a peptide hormone? 3. Explain the role of the hypothalamus. 4. Explain the role of the pituitary gland (posterior and anterior). 5. Name the endocrine glands covered in this chapter, the hormone(s) they produce, and the function of each hormone. You may want to set up a table. || **Endocrine Gland** || **Hormone Produce** || **Function of Hormone** ||
 * Both use chemical signals when responding to changes that might threaten homeostasis
 * The nervous system is composed of neurons and the endocrine system is composed of glands
 * Communication for the nervous system depends on nerve impulse conducted in the axon and the endocrine system has growth hormones that stimulate the growth of long bones
 * a steroid hormone has four carbon rings ( peptides, proteins, glycoproteins, and modified amino acids)and they are all derived from cholesterol
 * It compares with peptide hormone because it has the same four carbon rings
 * regulates the internal environment through the autonomic system (controls heartbeat, body temperature, and water balance)
 * Also controls the glandular secretion of the pituitary gland
 * The pituitary gland is connected to the the hypothalamus by a stalklike structure
 * the posterior is where the hormones pass through the axon and stored in the axon ending and secretes oxytocin and antidiuretic hormone
 * the anterior produces six types of hormones(**thyroid-stimulating hormone, adrenocorticotropic hormone, gonadotropic hormone, prolactin, melanocyte-stimulating hormone, and growth hormone**) some of which control other endocrine glands
 * Hypothalamus || inhibiting hormones || regulate the anterior pituitary ||
 * Pituitary || ADH,TSH,ACTH,FSH,PL,GH || determines growth,water reabsorption,stimulates thyroid,milk production, cell division ||
 * Thyroid || triiodothyronine || increases metabolic rate, and regulates growth and development ||
 * Parathyroid || Parathyroid hormone (PTH) || raises blood calcium level ||
