ANATOMY TEST PAPER QUESTIONS
ANSWERS GRADED A+
◉ a group of cells that work together to perform a particular function is
a(n)
a. tissue
b. organ
c. molecules
d. compounds
e. organism.
Answer: a. tissue
◉ what process occurs when amino acids build new proteins (select all
that apply):
a. metabolism
b. anabolism
c. catabolism
d. responsiveness
e. differentiation.
Answer: a. metabolism &
b. anabolism
,◉ how are reproduction, differentiation, & growth related?.
Answer: reproduction occurs through the fertilization of an ovum by a
sperm cell to form a zygote, followed by repeated cell divisions & the
differentiation of these cells. growth is an increase in body size that
results from an increase in the size of existing cells, an increase, in the
number of cells, or both.
◉ the two organ systems that predominantly regulate & maintain
homeostasis are the
a. cardiovascular & integumentary systems
b. nervous & endocrine systems
c. cardiovascular & respiratory systems
d. respiratory & muscular systems
e. urinary & integumentary systems.
Answer: b. nervous & endocrine systems
◉ which body fluid fills the narrow spaces between cells & tissues?
a. lymph
b. blood plasma
c. interstitial fluid
e. vitreous body.
Answer: c. interstitial fluid
,◉ describe the differences between positive & negative feedback
systems.
Answer: a positive feedback system will strengthen or reinforce a
change in one of the bodies controlled conditions while a negative
feedback system will reverse a change in a controlled condition
◉ hormonal or electrical signals are sent from the control center to the
a. receptors
b. stimulus
c. afferent pathway
d. effectors
e. efferent pathway.
Answer: d. effectors
◉ a component that detects decreasing oxygen concentrations in blood
would be the
a. receptor
b. muscle
c. response
d. effector.
Answer: a. receptor
◉ if blood concentrations of thyroid hormones increase above a certain
level, thyroid releasing hormone (TRH) neurons in the hypothalamus are
inhibited & stop secreting TRH. this is an example of:
, a. negative feedback
b. positive feedback.
Answer: a. negative feedback
◉ cardiomyopathy worsens as the heart weakens. swelling in the legs
occurs & is classified as a (select all that apply):
a. symptom
b. disorder
c. disturbance
d. disease
e. sign.
Answer: b. disorder &
c. disturbance &
e. sign
◉ describe the anatomical position.
Answer: in the anatomical position, the subject stands erect facing the
observer w/ the head level & the eyes facing forward. the feet are flat on
the floor & directed forward & the arms are at the sides w/ the palms
turned forward
◉ put the cavities in order from broadest to most specific in which the
lungs are located
a. thoracic, ventral, parietal pleura, visceral pleura
