COMPLETE QUESTIONS AND SOLUTIONS
GRADED A+
● catabolism. Answer: that break down molecules, releasing energy.
● anabolism. Answer: the process of building up larger molecules from
smaller ones.
● 3 things that effect growth in the body size. Answer: 1. increase in the
size of existing cells
2.increase in the number of cells
3.increase in the size of material between the cells
● differentiation. Answer: unspecialized cells becomes specialized
● reproduction is the formation of new cells for? (2). Answer: 1. tissue
growth, repair or replacement
2. production of a new individual
● fluid within the cells. Answer: intracellular fluid
,● fluid outside the cells. Answer: extracellular fluid
● ECF that fills narrow space between cells of tissues. Answer:
interstitial fluid
● what is the monitored variable called in a feedback loop. Answer:
controlled condition
● what is the stimulus. Answer: any disruption that changes a controlled
condition
● what's the receptor. Answer: body structure monitoring the changes of
a controlled condition and sends inputs
● what is an afferent pathway-input. Answer: flows towards the control
center (nerve impulse or chemical signal)
● what is the control center. Answer: sets the range of values within
which a controlled condition should be maintained; evaluates the input it
receives from receptors and generates output commands when they are
needed
● efferent pathway. Answer: flow away from control center to effector
,● effector. Answer: body structure receiving output and brings about
change and produces a response that alters the controlled condition
● negative feedback system. Answer: reverses a change in a controlled
condition
● positive feedback loop. Answer: strengthens or reinforces a change in
the controlled condition until its interrupted-effector produces a response
that reinforces the initial change-child birth
● disorder. Answer: abnormality of a structure or function
● disease. Answer: illness characterized by a recognizable set of signs
and symptoms
● symptom. Answer: subjective changes not visible to the observer
● sign. Answer: objective changes visible to the observer (doctor)
● prone. Answer: body is lying face down
● supine. Answer: body is lying face up
, ● ipsilateral. Answer: same side
● contralateral. Answer: different sides
● superficial. Answer: towards the surface of the skin
● deep. Answer: away from surface of the skin
● sagittal plane. Answer: divides the body into left and right
● Midsagittal (median) plane. Answer: divides into equal left and right
sides
● parasagittal plane. Answer: unequal sides left and right
● fronta (coronal plane). Answer: divides front and back
(anterior/posterior)
● transverse plane. Answer: superior and inferior top and bottom
(horizontal plane cross-sectional)
● oblique plane. Answer: anything but 90 degrees
