Type of glands that secrete hormones, called ductless |
|
|
Exocrine glands |
Type of glands that secrete into ducts (e.g. let, sweat glands, sebaceous glands) |
|
|
Tropic hormones |
Hormones that are aimed at a target |
|
|
Biorhythms |
Describes this pattern of secretion: Cortisol secretion is highest in the morning (8am), lowest in the evening (midnight) |
|
|
Biorhythm |

|
Target tissue (organ) |
Describes a specific tissue or organ to which a hormone binds |
|
|
Negative feedback control |
Example: Corticotropin - releasing hormone (CRH) > Stimulates the release of adrenocortictropic hormone (ACTH) ♢ ACTH stimulates > the secretion of cortisol > as the blood level of cortisol increases > it shuts off further secretion of ACTH and CRH |
|
|
Positive feedback control |
A self-amplification cycle "GIVE ME MORE" in which a change is the stimulus for an even greater change in the same direction |
|
|
Receptors |
Hormones bind to these special areas in the cell or on the surface of the cell membrane of the target tissue |
|
|
Second messanger chemical |
