🗑
|
||||
| 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
🗑
|
||||

🗑
|
||||
| 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
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
