2) Which of the following is NOT under control of the Medulla
Oblongata in the central nervous system?
a) Blood pressure
b) Vomiting reflex
c) Respiration
d) Cephalic digestive reflexes
e) Defecation reflex
f) All of the above are under medullary control
3) Metabolic rates of two rats are measured as ml O2 consumed/kg
body weight/hour. Rat A is normal, with a basal metabolic rate of
1500. Rat B has had its thyroid gland removed (thyroidectomized),
and has a basal metabolic rate of 1300. Rat C has had its pituitary
gland removed (hypophysectomized), and has a basal metabolic rate
of 1300. Predict how each rat’s metabolic rate should respond to
injections of the anterior pituitary hormone, thyroid-stimulating
hormone (TSH; Thyrotropin):
a) Rat A is 1600, Rat B is 1600, Rat C is 1600
b) Rat A is 1600, Rat B is 1300, Rat C is 1600
c) Rat A is 1600, Rat B is 1600, Rat C is 1300
d) Rat A is 1600, Rat B is 1300, Rat C is 1100
4) Which of the following is the pathway of absorption and
delivery of dietary fats and cholesterol to most bodily
tissues?
a) HDL-cholesterol to liver --> Apoproteins combine with
lipids to form chylomicrons --> lymph --> LDL-cholesterol to
peripheral tissues.
b) Apoproteins combine with lipids to form chylomicrons -->
blood --> HDL-cholesterol to liver --> LDL-cholesterol to
peripheral tissues.
c) Apoproteins combine with lipids to form chylomicrons -->
lymph --> HDL-cholesterol to liver --> LDL-cholesterol to
peripheral tissues.
d) LDL-cholesterol to liver --> Apoproteins combine with
lipids to form chylomicrons --> blood --> HDL-cholesterol to
peripheral tissues.
e) Apoproteins combine with lipids to form chylomicrons -->
LDL-cholesterol to liver --> lymph --> HDL-cholesterol to
peripheral tissues.
5) A patient's blood profile shows abnormally high levels of
TRH, low levels of thyroxine, and low levels of TSH. The patient is
correctly diagnosed with
a) Primary hypersecretion disorder
b) Secondary pituitary hypersecretion disorder
c) Secondary hypothalamic ("tertiary") hypersecretion
disorder
d) Primary hyposecretion disorder
e) Secondary pituitary hyposecretion disorder
f) Secondary hypothalamic ("tertiary") hyposecretion
disorder
