which hormone is incorrectly paired with its stimulus?
a) cck fatty foods
b) secretin acid in the small intestine
c) gip glucose in the small intestine
d) motilin acid in the stomach
e) gastrin peptides, increased sympathetic activity
3) milly has just received a kidney transplant and is taking cyclosporin a, a drug that
suppresses cytotoxic t cells. what does this medication do?
a) prevents inflammation from destroying the transplanted kidney
b) depresses hematopoiesis
c) prevents rejection
d) increases the number of antibodies in the blood
e) none of the answers are correct.
4) match these brain areas with their descriptions.
a. cerebellum
b. hypothalamus
c. thalamus
d. cerebrum
composed of many small nuclei, an area that integrates as well as relays sensory
information that passes through it
5) match the condition with the description.
a. acromegaly
b. adrenogenital syndrome
c. cretinism
d. dwarfism
e. exophthalmus
this condition results from excess androgens in females.
6) match these functions with the correct brain area.
a. medulla oblongata
b. pons
c. midbrain
d. reticular formation
small area that relays signals for auditory and visual reflexes as well as eye movement
7) hemophilia, color blindness, and duchenne muscular dystrophy occur more often in
males than females. why?
a) these traits are carried only on the x chromosome.
b) since there is no matching gene on the y chromosome, the traits are expressed more
readily in males.
c) testis-determining factor (tdf) causes these diseases.
d) these diseases develop due to the lack of estrogen and progesterone.
e) these traits are carried only on the x chromosome and since there is no matching gene
on the y chromosome, the traits are expressed more readily in males.
8) if you were in a desert without a food source, which nutrient would you like to have
stored in your body in a large amount?
a) protein
b) glycogen
c) calcium
d) fat
e) vitamin b6
9) match these functions with the correct brain area.
a. medulla oblongata
b. pons
c. midbrain
d. reticular formation
network to coordinate arousal and sleep, but also involved in blood pressure regulation
and pain modulation
10) match each term with the appropriate description.
a. peptide hormone
b. steroid hormone
c. amino acid-derived hormone
d. anterior pituitary
e. hypothalamus
f. posterior pituitary
storage and release site for oxytocin
11) in normal adults, red blood cells are formed in
a) the liver.
b) the spleen.
c) red bone marrow.
d) yellow bone marrow.
e) lymph nodes.
12) match the cell type with its description.
a. lymphocytes
b. neutrophils
c. monocytes
d. eosinophils
e. basophils
these cells are related to mast cells, and both release chemical mediators such as
histamine and heparin, which aid in the immune response.
13) atp synthase transfers the ________ energy of the h+ ions to the high-energy
phosphate bond of ________.
a) potential, nadh
b) potential, atp
c) kinetic, nadh
d) kinetic, atp
e) none of the answers are correct.
14) because of their smooth muscle component, the structures of the lower respiratory
system that can most alter airway resistance are the ________.
15) why does there seem to be a link between smell and memory?
16) in the autorhythmic cells, the ________ channels open when the cell membrane
potential is -60 mv. these channels are permeable to ________ and ________.
17) what are the two distinct endocrine cell types that comprise the thyroid gland, and
what do they secrete?
18) receptors that work through second messenger systems are called ________
receptors.
19) how many liters of blood are distributed between the pulmonary and systemic
circuits in a "typical" person? assume 20% of the blood is in the lungs at any moment. if
the cardiac output is 5 l/min, how long will it take a drop of blood to flow from the right
ventricle to the left ventricle?
20) draw two graphs that represent the alpha-gamma coactivation:
1> muscle length as a function of time
2> action potentials of spindle sensory neuron as a function of time
21) describe anorexia nervosa and diabetes mellitus, and how they resemble each other.
22) a study was done in 1998 by dr. benjamin levine to explore the role of altitude
training in athletic performance. first he trained athletes at low altitude, then measured
their finish times in a 5 kilometer run. then the athletes were placed into one of the
following groups: i, living and training at high altitude; ii, living at high altitude and
training at low; or iii, living and training at low altitude. the athletes were then retested
in another low-altitude 5 k race. in this study, what are the control and experimental
data? what are the dependent and independent variables? the results are expressed as
average change in speed of each group. i: -3.4 sec., ii: +13.4 sec., iii: -26.7 sec. graph
and interpret the results. did the results surprise you? why or why not? propose some
explanations for the lower performance by the live high-train high group. why wasn't
there a live low-train high group?
23) what is the difference between cell movements in response to outside forces and
cell-generated movements (in response to specific cell activity)? (hint: do red blood
cells move because of rbc activity? what causes cell movements associated with
cytokinesis?) using the index of your text to guide you to relevant sections in other
chapters (look up entries for the various cytoskeletal proteins), explain the different
types of movements that cells generate.
