What happened to the neurotransmitter release when switched from the control extracellular fluid to the extracellular fluid with no calcium?
There is no neurotransmitter release from the axon terminal when there are no calcium ions in the extracellular solution. This is because the exocytosis of the synaptic vesicles is calcium dependent.
What is the chloride ion concentration in intracellular fluid?
Every Laboratory has specfic values that their Lab Medicine Docs have signed off as being Normal Values, however, generally The Intracellular Concentration of Chloride in Eukaryotic Cells is 5 milliMoles. The Extracellular Concentration of Chloride is 110 mM. The Intracellular Concentration of Calcium is < 1 mM The Extracellular Concentration of Calcium is 1.8 mM
What 2 hormones are involved in regulating the blood calcium level?
Parathyroid hormone provides a powerful mechanism for controlling extracellular calcium and phosphate concentrations by regulating intestinal reabsorption, renal secretion, and exchange between the extracellular fluid and bone of these ions. Also, Calcitonin, which is a peptide hormone secreted by the thyroid gland, tends to decrease plasma calcium concentration and usually has effects that are opposite to those of the parathyroid hormone.
The main hormone that acts on the kidneys to regulate sodium ion concentration of the extracellular fluid is?
Aldosterone
Is The most abundant cation in intracellular fluid is potassium?
No, it is potassium.
True or False The most abundant negative ion in extracellular fluid is calcium?
False. It's Chloride
What is the Most abundant positive electrolyte in extracellular fluid?
Sodium ion is the most concentrated ion in the extracellular fluid.
What is found in extracellular fluid?
The principal elements in the extracellular fluid are sodium, potassium and calcium.
What happened to the neurotransmitter release when switched from the control extracellular fluid to the extracellular fluid with no calcium?
There is no neurotransmitter release from the axon terminal when there are no calcium ions in the extracellular solution. This is because the exocytosis of the synaptic vesicles is calcium dependent.
What is the most abundant anion in extracellular fluid?
Extracellular fluid refers to all body fluid outside of cells. The most abundant anion in the extracellular fluid is chloride (Cl-).
What is the most cation extracellular fluid?
calcium ; sodium
What is the charge of intercellular fluid?
The intracelluar fluid is negative with respect to the extracellular fluid.
Where is Extracellular fluid found in body?
proteins and electrolytes including the liquid in blood plasma and interstitial fluid
After nervous stimulation of the muscle cell has ceased the calcium does what?
is actively pumped into the extracellular fluid for storage.
What after nervous stimulation of the muscle cell has ceased the calcium?
is actively pumped into the extracellular fluid for storage.
After nervous stimulation of the muscle cell has ceased what happens to the calcium?
calcium is actively pumped into the extracellular fluid for storage until the next contraction
Most important electrolyte for maintenance of osmotic pressure and volume?
The most abundant positive ion or cation in the extracellular fluid is sodium (Na+). Chloride (Cl-) is the most abundant negative ion or anion.
