Nurs 210 Exam 1 umich Questions With
Correct Answers
homeostasis - CORRECT ANSWER✔✔-maintenance of relatively stable
| | | | | | |
internal conditions despite continuous changes in the environment
| | | | | | |
dynamic state of equilibrium - CORRECT ANSWER✔✔-always
| | | | | | |
readjusting as needed and is maintained by contributions of all organ
| | | | | | | | | | |
systems
what systems are responsible for communication? - CORRECT
| | | | | | | |
ANSWER✔✔-nervous and endocrine system | | |
what are internal variables in the body that need to be controlled? -
| | | | | | | | | | | | |
CORRECT ANSWER✔✔-temperature, blood glucose, blood pressure,
| | | | | |
etc.
negative feedback mechanism - CORRECT ANSWER✔✔-output shuts off
| | | | | | | |
the original effect of the stimulus or reduces its intensity ex: blood
| | | | | | | | | | | |
glucose levels, body temperature
| | |
,positive feedback mechanism - CORRECT ANSWER✔✔-initial response
| | | | | | |
exaggerates the original stimulus so that further responses are even
| | | | | | | | | |
greater ex: blood clotting, labor contractions
| | | | |
components of a feedback loop - CORRECT ANSWER✔✔-receptor, | | | | | | | |
control center, effector| |
receptor (first component) - CORRECT ANSWER✔✔-sensor that
| | | | | | |
monitors the environment, it responds to stimuli by sending information
| | | | | | | | |
along the afferent pathway to the second component
| | | | | | | |
control center (second pathway) - CORRECT ANSWER✔✔-determines
| | | | | | |
the set point, analyzes the input it receives by comparing it to a set
| | | | | | | | | | | | | |
point and determines an appropriate response, information then flows
| | | | | | | | |
from the control center along the efferent pathway to the third
| | | | | | | | | | |
component
effector (third component) - CORRECT ANSWER✔✔-carries out the
| | | | | | | |
control center's response to stimulus, results of the response then feed
| | | | | | | | | | |
back to influence the effect of the stimulus, either reducing it (negative)
| | | | | | | | | | | |
so that the whole process is shut off, or enhancing it (positive)
| | | | | | | | | | |
afferent pathway of a feedback loop - CORRECT ANSWER✔✔-from the
| | | | | | | | | |
receptor to the control center | | | |
,efferent pathway of the feedback loop - CORRECT ANSWER✔✔-from
| | | | | | | | |
the control center to the effector
| | | | |
chemical level - CORRECT ANSWER✔✔-atoms, molecules, organelles
| | | | | |
cellular level - CORRECT ANSWER✔✔-single cell
| | | | |
tissue level - CORRECT ANSWER✔✔-groups of similar cells
| | | | | | |
organ level - CORRECT ANSWER✔✔-two or more types of tissues
| | | | | | | | |
organ system level - CORRECT ANSWER✔✔-group of organs that work
| | | | | | | | | |
together
organismal level - CORRECT ANSWER✔✔-all organ systems combined
| | | | | | |
components of the skeletal system - CORRECT ANSWER✔✔-bones,
| | | | | | | |
joints, cartilage, ligaments, tendons
| | |
functions of the skeletal system - CORRECT ANSWER✔✔-protects and
| | | | | | | | |
supports organs, provides framework for movement, blood cells formed
| | | | | | | |
in bones, bones store minerals
| | | | |
, components of the integumentary system - CORRECT ANSWER✔✔-hair,
| | | | | | | |
skin, nails
|
functions of the integumentary system - CORRECT ANSWER✔✔-
| | | | | | |
external body covering, protects deeper tissues, synthesizes vitamin D,
| | | | | | | | |
houses cutaneous receptors, sweat and oil glands
| | | | | |
components of the nervous system - CORRECT ANSWER✔✔-brain,
| | | | | | | |
nerves, spinal cord | |
functions of the nervous system - CORRECT ANSWER✔✔-fast-acting
| | | | | | | |
control system, responds to internal and external changes, activates
| | | | | | | | |
appropriate muscles and glands | | |
components of the muscular system - CORRECT ANSWER✔✔-skeletal
| | | | | | | |
muscle, smooth muscle, cardiac muscle
| | | |
functions of the muscular system - CORRECT ANSWER✔✔-manipulation
| | | | | | |
of the environment, locomotion, and facial expression; move bones
| | | | | | | | | |
when they contract; maintains posture; produces heat
| | | | | |
components of the cardiovascular system - CORRECT ANSWER✔✔-
| | | | | | |
heart, blood vessels
| |
