18
Q

Exocrine function of pancreas

A

19
Q

Gout

A

Build up of Uris acid in blood from breakdown of purines, damages joints and causes inflammation

20
Q

Dislipidaemia TI

A

Defective lipoprotein lipase, no Coronary artery disease

21
Q

Type IIa dislipidaemia

A

Defective LDL receptor, coronary artery disease

22
Q

Posterior pituitary gland secretions

A

Prolactin, oxytocin

23
Q

Actions of ACTH

A

Increase cholesterol esterase, more cholesterol, and increased production of cortisol

24
Q

Actions of cortisol

A

Increased proteolysis, lipolysis, gluconeogenesis, glycogenolysis, decreased immune system

25
Q

Excess cortisol

A

Hyperglycaemia, deposition of fat, easy bruising, hypertension

26
Q

Effects of aldosterone

A

Increased sodium reabsorption in exchange for K in the kidneys

27
Q

Calcium uses in the body

A

Hormone secretion, nervous conduction, activation of enzymes, muscle contraction, exocytosis

28
Q

Transport of Calcium

A

Free, anionic sites of serum proteins, complexed with low weight anions eg citrate

29
Q

Affect chief cells have when bound to calcium

A

Increased PLC production, decreased adenylate cyclise, hence decreased cAMP and PTH

30
Q

Effects of PTH

A

Increased calcium release from bone

Increased reabsorption in distal convoluted tubule

31
Q

PTHrP

A

Like PTH but no more calcitirol formed as no increased hydroxylase enzyme, hence humeral hypercalcaemia of malignancy

32
Q

Hypocqlcaemia

A
Paraesthesia
Paralysis
Convulsions
Involuntary muscle contractions
Tetany
33
Q

Hypercalcaemia

A

Kidney stones, constipation, dehydration, tiredness, depression
