Question | Answer |

These organs produce both hormones and exocrine products. | Pancreas and gonads |
Chemicals (not considered hormones)that exert their effects on the same cells that secrete them. | Autocrines |
Locally acting chemicals (not considered hormones)that affect cells other than those that secrete them. | Paracrines |
Regulate metabolic function of other cells, lag times from seconds to hours, usually prolonged effects, classified as amino-acid based or steroids. | Hormones |
These hormones difuse easily into their target cells. | Steroid hormones |
One hormone cannot exert its effects without another hormone being present. | Permissivenness |
More than one hormone produces the same affects on a target cell. | Synergism |
One or more hormone opposes the action of another hormone. | Antagonism |
hormones are released in response to these three differnt types of stimuli. | Humoral, Neural, and Hormonal |
Secretion of hormones in direct response to changing blood levels of ions and nutrients. | Humoral Stimuli |
Nerve fibers stimulate hormone release. | Neural stimuli |
Release of hormones in response to hormones produced by other edocrine organs. | Hormonal stimuli |
Two lobed organ that secretes nine major hormones. | Pituitary gland |
Posterior lobe (neural tissue) of the pituitary gland. Receives, stores and releases hormones from the hypothalamus. | Neurohypophysis |
Anterior lobe of pit. gland, made up of glandular tissue, synthesizes and secretes a number of hormones. | Adenohypophysis |
A downward growth of the hypothalmic neural tissue. | Posterior lobe |
Lobe of the pit. gland that is an outpocketing of the oral mucosa. | Anterior lobe |
The hormones of the adenohypophysis that regulate the activity of other endocrine glands. | GH, TSH, ACTH, FSH, LH, and PRL |
Is enzymatically split into ACTH, opiates,and MSH. | POMC--pro-opiomelanocortin |
Tropic hormones that are released by a chemical sending stimulus from the hypothalamus to the anterior pituitary. | TSH, Adrenocorticotropic hormone, FSH, LH |
