QUIZ 2 Flashcards
meaning “to set in motion”
Hormon
General Functions of ENDOCRINE glands
Regulatory: constancy of chemicals
- Morphogenesis: Growth/Development
- Integrative:
Released because of critical levels of ions/Nutrients
Humoral Stimulus
Released caused by neural input
Neural Stimulus
Released caused by another hormone
Hormonal Stimulus
Enters circulation and binds specific cells at distant
site to elicit response
Endocrine
Enters interstitial spaces and binds specific receptor in adjacent gland for its effe
Paracrine
Enters interstitial space and binds specific receptor
cell of the origin to autoregulate its function
Autocrine
Remains associated with plasma membrane and acts on adjacent receptor by direct cell to cell
Juxtacrine
released to lumen of gut, binds to cells of gut
Exocrine
moves to extracellular space, binds to receptors in nearby cells for its action
Neurocrine
enters the circulation, interacts with receptor of
cells of distant sites
Neuroendocrine
crosses synapse and binds to receptors in another neuron affecting its action
Neurotransmission
cyclal patterns of hormone release
Biorhythms
Enumerate the 3 biorhythms
- circardian/diurnal
2: Infradian - Ultradian
Hormone concentration is controlled by:
- Rate of production/Synthesis
- Efficiency of delivery
- Metabolism
Some peptide hormones are produced______
cleavage/break-up
from large protein
Some peptide hormones are produced______
cleavage/break-up
from large protein
hydrophobic, from cholesterol and needs a carrier protein
Steroids
precursor of steroids
cholesterol
Enumerate 3 Relationship or Interaction of hormones to target cells:
- Permissiveness
- Synergism
- Antagonism
when 1 hormone cannot exert its full effect without another hormone being present
Permissiveness
more than one hormone produce same effects on target cells
Synergism
one hormone opposes the action of another hormone
Antagonism
