positive feedback
circadian feedback
status quo feedback
negative feedback
open loop feedback
What do autocrine cells target?
All cells in the body
Nearby cells
The cell that secreted the hormone
Which of the following is a primary endocrine organ?

Intestines
Target cells make fewer receptors for a particular hormone when the level of that hormone is elevated for longer periods of time. This process is called:
synergism
the second-messenger system
downregulation
upregulation
What type of hormone usually travels in the blood with no help from transport proteins?
hydrophilic hormones
bound hormones
hydrophobic hormones
neurotransmitters
Which has a longer half-life?
Hydrophilic Hormones
Hydrophobic Hormones
Down-Regulation
Up-regulation
This type of hormone can cross the plasma membrane and interact with receptors in the cytosol or nucleus:
Steroid hormone
Amine hormone
Peptide hormone
Protein hormone
Increasing levels of calcium in the blood stimulate the release of calcitonin. This type of stimulus is known as:
positive stimulation
neural stimulation
hormonal stimulation
humoral stimulation
Which gland controls the release of hormones from the anterior pituitary?
posterior pituitary
hypothalamus
adrenal cortex
thyroid gland
