Hormones

1. Compare and Contrast the endocrine system and the nervous system. (At least three things)

1. They both have to work together to regulate the activities of the other systems, 2. They both use chemical signals when they respond to changes that might threaten homeostasis, but they have different means of delivering these signals. 3. The difference between the chemical signals is that the nervous system uses neurons, while the endocrine uses sensory receptors.

2. What is a steroid hormone? How does it compare to a peptide hormone? - Peptide hormones are growth hormones (includes peptides, proteins, glycoproteins and modified amino acids). The steroid hormone is also a growth hormone that has the same complex four carbon rings.

3. Explain the role of the hypothalamus. - The hypothalamus regulates certain metabolic processes and other autonomic nervous system activities.

4. Explain the role of the pituitary gland (posterior and anterior). - The pituitary gland regulates and secretes hormones regulating homerostasis. The anterior pituary synthesizes and secretes important endocrine hormones such as ACTH, TSH, and prolactin. The posterior pituitary secretes oxycotin and andiuretic hormones,

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. -
 * Hypothalamus || It inhibits hormones || Regulates the anterior pituitary ||  ||
 * Pituitary || TSH, ADH, ACTH, FSH || calculates growth, the amount of water reabsorbed, stimulates thyroid, milk production, cell division ||  ||
 * Thyroid || triodothyonine || increases metabolic rate, regulates growth ||  ||
 * Parathyroid || parathyroid hormone || raises blood calcium level ||  ||
 * Thyroid || triodothyonine || increases metabolic rate, regulates growth ||  ||
 * Parathyroid || parathyroid hormone || raises blood calcium level ||  ||
