the result of a loss of both mineralization and the organic matrix of bone. In both rickets and osteomalacia, bones become soft and often deformed due to improper calcification.

16
Q

is the main extracellular cation found outside the cells (extracellular) and blood

A

Sodium (Na+)

17
Q

is the major cation found in greater concentrations within the cells (intracellular fluid).

A

Potassium (K)

18
Q

is the negatively charged anion that counterbalance the role of positively charged cations (K and Na).

19
Q

is a trace mineral that is a dietary essential for animals.

20
Q

(slipped tendon) occurs with Mn deficiency. Affected birds will have a malformation of the tibiotarsal joint, bending of long bones, and gastrocnemius tendon slipping from its condyle

21
Q

Many skeletal abnormalities are associated with manganese deficiency and are related to default in mucopolysaccharide synthesis. Lameness, shortening and bowing of legs, and enlarged joints in pigs, sheep, goats,

A

Mucolypolysaccharide synthesis

22
Q

is widely distributed in the animal body. High concentrations of Zn can be found in the liver, bones, and animal body coverings, such as hair, wool, skin, and feathers

23
Q

a low molecular weight binding protein, has a high affinity for binding to Zn and is involved in the transfer of Zn from intestinal mucosa cells to plasma and metabolism of Zn

A

Metallothionein

24
Q

is present in all cells of the animal body, but the largest proportion of the body’s iron is present as a component of the protein molecule hemoglobin (> 65%) and myoglobin (> 4%).

25
Q

is a complex protein present in red blood cells consisting of a haem group (porphyrin) containing ferrous (Fe2+) iron and a protein (globin)

A

Hemoglobin

26
Q

conditions in the intestine enhance iron absorption because inorganic iron in the ferrous form is more readily absorbed than iron in the ferric state

27
Q

required for hematopoiesis (red blood cell formation).

28
Q

Most of the Cu found in the blood is bound to the plasma protein

A

Ceruloplasmin

29
Q

cysteine-rich protein, is involved in the absorption. After absorption, mainly in duodenum, Cu is complexed with plasma protein albumin and mainly stored in the liver, where it is used for ceruloplasmin and other proteins needed by the body

A

Metallothionein

30
Q

is a component of glutathione peroxidase, an enzyme that deactivates lipid peroxides that are formed during lipid oxidation

31
Q

is a constituent of vitamin B12. ___ is widely distributed in tissues such as in the liver, kidneys, and bones

32
Q

The only known function of ___ is as a constituent of thyroxin (tetra iodothyronine) and triiodothyronine, thyroid gland hormones.

33
Q

stimulates cellular oxidative processes and regulates the basal metabolic rate. The thyroid gland contains the highest concentration of I and is followed by other organs such as the stomach, intestine, mammary glands, and skin.

34
Q

could occur in animals eating I-deficient forages or those feeds containing goitrogens (substances that interfere with the iodination process in thyroxin synthesis)

35
Q

is a cofactor of the enzyme xanthine oxidase and nitrogenase.

A

Molybdenum (Mo)

36
Q

has been identified as an essential nutrient in animals
