PHYSIOLOGY

1.       Thyroxine is synthesized from the amino acid tyrosine only

2.       Thyroid hormones are thermogenic hormones

3.       Grave’s disease is caused by hypothyroidism

4.       Insulin is an important hormone which is secreted by both the alpha and beta cells of the islet of langerhans

5.       Insulin is the only hormone that has a blood glucose lowering effect

6.       Cortisol increases the blood glucose level

7.       Type 1 diabetes mellitus is called Non-insulin dependent diabetes mellitus

8.       The innermost layer of the adrenal cortex is called the zona fasculata

9.       Adrenal medulla secretes only Nor-epinephrine and epinephrine

10.   Drugs that inhibit mono-amine oxidase(MAO) cause increase in sympathetic discharge

11.   Addison’s disease arises as a result of hyperactivity of the adrenal cortex

12.   Increased aldosterone level leads to increase in arterial blood pressure

13.   Calcitonin has an antagonistic action on parathyroid hormones

14.   Growth hormones has a synergistic effect on insulin

15.   Antidiuretic hormones and oxytocin are produced in the posterior pituitary gland

16.   The   External sphincter of the bladder is made up of smooth muscle

17.   Renin converts angiotensinogen to angiotensin ii

18.   The GFR of a normal human being of average size is 125ml/s

19.   The renal blood flow is 1273ml/min

20.   The mesangial cells are also called stellate cells

21.   The human PCT is about 15mm long and 25micrometre in diameter

22.   The filtration fraction is normally 0.16-0.20

23.   Natriuretic occurs when saline is infused intravenously and a decrease in sodium ion excretion when ECF volume is reduced

24.   Normally 99% of sodium ion that is filtered is normally reabsorbed

25.   Osmotic diuresis is produced by the administration of substances such as mannitol

26.   Micturition is fundamentally a spinal reflex facilitated and inhibited by higher brain centres

27.   The sympathetic nerve fibres are responsible for bladder emptying

28.    Enuresis is never a normal physiological phenomenon

29.   Oncotic pressure is downward pulling

30.   Autoregulation of GFR elicits sodium reabsorption

31.   The erosion of the endometrial layer is spastic

32.   The testes are regulated at 36.5^o C

33.    Ejaculation is under parasympathetic control

34.   Ade was scared of the criminal, then he was forced to pass out urine unwillingly. From this statement, does it mean the sympathetic nervous system is responsible for bladder emptying

35.   A plot of intravesical pressure against the volume of fluid in the bladder is called a cystometrogram

36.   SGLT 2 is an example of primary active transport

37.   Active transport of NaCl out of the thick ascending limb is capable of establishing only a conc gradient of 300mOsm/L

38.   Prostaglandins is greatly involved in labour

39.   Vasopressin 1 and 2 has receptors on the kidney

40.   Increased Blood volume is co with increased plasma osmolarity
