Endocrine Glands
| Question | Answer |
|---|---|
| The endocrine system communicates through chemical signals called what? | Hormones |
| The endocrine system and its hormones help regulate metabolic processes involving WHAT 3 things? | Carbohydrates, proteins, fats |
| The endocrine system is composed of endocrine glands that are widely distributed throughout the WHAT? | Body |
| Endocrine glands secrete the chemical substance called WHAT? | Hormones |
| Endocrine glands are ductless glands T or F? | True |
| Endocrine glands secrete hormones directly into the WHAT and not into ducts. | Blood |
| A hormone is a chemical messenger that influence or control the activities of other WHAT and WHAT? | Tissues, organs |
| Hormones are classified as either WHAT or WHAT? | Proteins (and protein related substances), steroids |
| Each hormone binds to a specific tissue called its WHAT? | Target tissue or organ |
| The thyroid hormone and insulin, have WHAT target tissues and therefore exert more widespread or generalized effects. | Many |
| Some hormones such as PTH(parathyroid hormone have WHAT target tissues and therefore exert fewer effects. | Fewer |
| Hormones bind to the WHAT sites of the cells of their target tissues? | Receptor |
| The two types of receptors are located on the outer surface of the WHAT membrane (membrane receptors) and located within the WHAT (intracellular receptors) | Cell, cell |
| There is a WHAT hormone for each receptor. | Specific |
| Protein hormones generally bind to the receptor sites located on the WHAT? | Cell membrane |
| Steroid hormones, which are lipid soluble, pass through plasma membrane of target cell and bind to receptors in the WHAT? | Nucleus |
| WHAT three mechanisms control the secretion of hormones? | Negative/Postitive feedback control loops, biorhythms, CNS (central nervous system) |
| Blood levels of most hormones are controlled by biorhythms. WHAT are two examples of biorythms? | Circadian (24 hour rhythm), monthly |
| The hypophysis AKA WHAT is a pea sized gland attached to the undersurface of the hypothalamus. | Pituitary gland |
| The pituitary gland has two main parts called the WHAT and WHAT pituitary glands? | Anterior, posterior |
| The secretions of the anterior and posterior lobes of the pituitary gland are dependent upon the WHAT (in different ways). | Hypothalamus |
| The hypothalamus is connected to the anterior pituitary gland through WHAT? | Capillaries (tiny blood vessels) |
| The hypothalamus is connected to the WHAT pituitary gland through tissue extension? | Posterior pituitary gland |
| This pituitary gland is composed of glandular epithelial tissue and is also called the adenohypophysis. | Anterior pituitary gland |
| The secretion of the WHAT pituitary gland is controlled by the hypothalamic secretion of hormones called releasing hormones and release-inhibiting hormones (release or inhibit) | Anterior |
| Neurohypophysis is also known as what pituitary gland? | Posterior pituitary gland |
| The posterior pituitary gland is controlled by the WHAT? | Hypothalamus |
| The posterior pituitary gland is an WHAT of the hypothalamus and composed of nervous tissue? | Extension |
| ADH and oxytocin are produced in the hypothalamus and transported to the WHAT gland and stored until needed? | Posterior pituitary gland (aka neurohypophysis) |
