16
Q

endocrine circuit type 1

A

sensory component = endocrine cell = target cell; sensor is separate

17
Q

endocrine circuit type 2

A

sensory component = primary endocrine gland = secondary endocrine gland = target cell; lots of (-) feedback

18
Q

modified amino acid CS

A

low weight; hydrophilic; tyrosine; thyroid hormone

19
Q

polypeptide CS

A

vary weight; hydrophilic; chain of AAs

20
Q

lipid-derived CS

A

low weight; lipophilic; steroids; cholesterol

21
Q

neuronal communication

A

release CS at synapse by pre-synaptic cell; fast and specific

22
Q

endocrine communication

A

release CS at capillary; slow and specific/general

23
Q

epithelial endocrine cell

A

non-neuronal secretory cells; derived from ectoderm, endoderm, and mesoderm

24
Q

neurosecretory endocrine cell

A

modified neuron; does not terminate at synapse; does terminate at capillary
