UPDATED EXAM WITH CORRECT ANSWERS. RATED A+.
neurons do what - CORRECT ANS: -conduct nerve impulses
what is the synapse - CORRECT ANS: -junction between two neurons
what makes up the central nervous system - CORRECT ANS: -brain and spinal cord
what three parts make up the brain - CORRECT ANS: -cerebrum, cerebellum, medulla
oblongata
what makes up the peripheral nervous system - CORRECT ANS: -sensory nerves and motor
nerves
How many cranial nerves are there - CORRECT ANS: -12
what nerve is the trigeminal nerve - CORRECT ANS: -5
what parts does the trigeminal nerve control - CORRECT ANS: -supplies sensation to the teeth
and jaw
what are the 2 components of the autonomic nervous system? - CORRECT ANS: -sympathetic
nervous system
parasympathetic nervous system
what nervous system "speeds things up" - CORRECT ANS: -sympathetic
what nervous system "slows things down" - CORRECT ANS: -parasympathetic
what nervous system has terminations in all level of the heart - CORRECT ANS: -sympathetic
nervous system
stimulation of the sympathetic nervous system causes what? - CORRECT ANS: -
vasoconstriction in general and increases the heart rate
what nervous system is important in maintaining blood pressure - CORRECT ANS: -
sympathetic
vasomotor is controlled by the - CORRECT ANS: -sympathetic nervous system
, the vasomotor does what - CORRECT ANS: -controls the diameter of the blood vessels
baroreceptors regulate what function - CORRECT ANS: -blood pressure with positional changes
the sympathetic or adrenergic effects of the autonomic nervous system involve what -
CORRECT ANS: -two effects A and B- these effect several tissues and organs
Alpha effect is what (only one alpha) - CORRECT ANS: -vasoconstriction
Beta effect is what (two beta categories) - CORRECT ANS: -seen in bigger organs, heart and
lungs
Beta 1 activity is where - CORRECT ANS: -heart related functions- such as increased heart rate
and strength of contraction
Beta 2 activity is where - CORRECT ANS: -pulmonary function of bronchiolar dilation (lungs)
Parasympathetic stimulation causes what - CORRECT ANS: -increased activity of digestive
tract and stimulates production of saliva and pharyngeal secretions. (atropine or Robinul can
counteract stimulations)
Automaticity - CORRECT ANS: -heart pumps on its own
Heart has four chamber- what are they - CORRECT ANS: -left atrium, right atrium, left ventricle,
right ventricle
Where does the left atrium receive blood from - CORRECT ANS: -from the lungs, via the
pulmonary vein- oxygen rich blood
Where does the right atrium receive blood from - CORRECT ANS: -from the peripheral (body's)
circulation and is oxygen poor
the ventricles receive blood from where - CORRECT ANS: -the atria
Ventricle anatomy - CORRECT ANS: -thicker walls
larger chambers
left ventricle is the thickest m.
Where does the right ventricle send blood - CORRECT ANS: -deoxygenated blood to the lungs
Where does the left ventricle send blood - CORRECT ANS: -oxygenated blood to the body/
peripheral circulation
