Cards

Term
Minerals
Definition
Solid, inorganic crystalline elements that cannot be decomposed or synthesized by the body
Term
Calcium location in the body
Definition
Found in skeleton and teeth
Term
Calcium functions
Definition
Plays a role in nerve transmission, muscle contraction, blood clotting
Term
Calcium deficiencies
Definition
Deficiencies result in rickets: a disease of the bony growth plate, and parturient paresis (in cows): muscle spasms (tetany) and muscle weakness (paresis)
Term
Phosphorus location in the body
Definition
Found in bone, phospholipid bilayer, and ATP
Term
Phosphorus functions
Definition
Formation of bones and teeth
Term
Phosphorus deficiencies
Definition
Pica: animals have a craving for unusual foods such as wood and other materials
Term
Magnesium location
Definition
Cofactor of enzymes
Term
Magnesium functions
Definition
Required for cellular respiration and heart function
Term
Magnesium deficiencies
Definition
Grass tetany: convulsions then death in most severe cases
Term
Sodium, potassium, and chloride location
Definition
Body fluids
Term
Sodium, potassium, and chloride functions
Definition
Maintain the optimal pH
Term
Sodium, potassium, and chloride deficiencies
Definition
Salt deficiency: salt poisoning or water deprivation
Term
Sulfur location
Definition
Amino acids: methionine, cystine, and cysteine; vitamins: biotin and thiamin; polysaccharides: chondroitin sulfate (found in cartilage, bone, and tendons) and heparin
Term
Sulfur functions
Definition
Lipid metabolisms, carbohydrate metabolism, energy metabolism, and blood clotting
Term
Sulfur deficiencies
Definition
Would also be linked to a protein deficiency, sulfur may need to be supplemented to create dispensable proteins in ruminants
Term
Hormones involved in calcium balance
Definition
Calcitriol and PTH (parathyroid hormone)
Term
Phytic acid
Definition
Reduces the solubility and digestibility of phosphorus, calcium, and protein and leads to various deleterious physiological cascades
Term
Phytate
Definition
Compounds that may bind phosphorus and reduce its absorption from the GI tract
Term
Electrolytes
Definition
Dissociate into ions in water, ions conduct electrical current, and have the greatest ability to cause fluid shifts
Term
Nonelectrolytes
Definition
Don't dissociate in water, no charged particles created
Term
ICF
Definition
Intracellular fluid: fluid found in cells
Term
ECF
Definition
Extracellular fluid: fluid found outside of cells
Term
Ions
Definition
Charged particles
Term
Cation
Definition
Positively charged particle
Term
Anion
Definition
Negatively charged particle
Term
Major cations found inside the cell
Definition
Potassium and magnesium ions
Term
Major cations found outside the cell
Definition
Sodium and calcium ions
Term
Major anions found inside the cell
Definition
Phosphate ion
Term
Major anions found outside the cell
Definition
Chloride ion
Term
Hormones that help regulate sodium balance
Definition
Aldosterone, ADH, and ANP
Term
Hormone that helps regulate potassium balance
Definition
Aldosterone
Term
DCAD
Definition
Dietary cation-anion difference
Term
Cobalt location and function
Definition
Required for B12, cofactors for enzymes involved in DNA synthesis and amino acid metabolism
Term
Cobalt deficiencies
Definition
Reduced appetite, anemia, and scaly ears
Term
Iodine location and function
Definition
Found in the thyroid gland, used in T3/T4 formation
Term
Iodine deficiencies
Definition
Hyperthyroidism in cats and hypothyroidism in dogs
Term
Iron location and function
Definition
Found in red blood cells and muscle, stored as ferritin
Term
Iron deficiencies
Definition
Anemia
Term
Thyroid hormones
Definition
Hypothalamus and pituitary gland are both in the brain, hypothalamus releases TSH, TSH triggers release of T3 and T4
Term
T3 and T4
Definition
Collectively called thyroxine
