electrolytes part 2 Flashcards
what are the structural functions of the calcium
Bone
Teeth
what are the neuromuscular functions of calcium
Control of Excitability
Release of neurotransmitters
Initiation of muscular contraction
enzymatic function of calcium
Coenzyme for coagulation factors
signaling function of calcium
intracellular second messengers
The calcium levels are affected by pH level. What happens to its levels when you experience acidosis and alkalosis
acidosis: hypercalcemia
alkalosis: hypocalcemia
inversely proprtional
hormones that regulate calcium level
PTH
Calcitriol or activated vitamin D3
Calcitonin
what are the inhibitors of PTH
Hypercalcemia
Calcitriol
what is released to compensate the fall of ionized calcium (free) in pasma
PTH
what hormone for for Ca regulation is pro blood
PTH
what hormone for Ca regulation is pro bone
calcitonin
true or false: calcitriol is inhibited by increase of PTH and decreased phosphate
false. it is stimulated by increased PTH and decreased phosphate. it is inhibited by decreased PTH and increased phosphate
what produces calcitonin
C-cells (parafollicular) of the thyroid gland
what is the result of the release of calcitonin
inhibits bone resorption = decreased Ca levels
it is also called as the hypocalcemic bone
calcitonin
what are the main functions of calcitriol or activated vit D3
stimulation of bone resorption
stimulation of Ca and PO4 absorption in the gut
what are the measurements of calcium
ISE, AAS, EFP
Precipitation of Ca
Formation of colored complexes
Removal of Ca
what are the components of O-cresolphthalein and its functions
8-hydroxyquinoline- bind to Mg
Urea- reduce turbidity
Ethanol- decrease the absorbance of blank
what is considered the second reference method for Ca
Atomic Absorption Spectrophometry
