neurons do what conduct nerve impulses what is the synapse junction between two neurons what makes up the central nervous system brain and spinal cord what three parts make up the brain cerebrum, cerebellum, medulla oblongata what makes up the peripheral nervous system sensory nerves and motor nerves How many cranial nerves are there 12 what nerve is the trigeminal nerve 5 what parts does the trigeminal nerve control supplies sensation to the teeth and jaw what are the 2 components of the autonomic nervous system? sympathetic nervous system parasympathetic nervous system what nervous system "speeds things up" sympathetic what nervous system "slows things down" parasympathetic what nervous system has terminations in all level of the heart sympathetic nervous system stimulation of the sympathetic nervous system causes what? vasoconstriction in general and increases the heart rate what nervous system is important in maintaining blood pressure sympathetic vasomotor is controlled by the sympathetic nervous system the vasomotor does what controls the diameter of the blood vessels baroreceptors regulate what function blood pressure with positional changes the sympathetic or adrenergic effects of the autonomic nervous system involve what two effects A and B- these effect several tissues and organs Alpha effect is what (only one alpha) vasoconstriction Beta effect is what( two beta categories) seen in bigger organs, heart and lungs Beta 1 activity is where heart related functions- such as increased heart rate and strength of contraction Beta 2 activity is where pulmonary function of bronchiolar dilation (lungs) Parasympathetic stimulation causes what increased activity of digestive tract and stimulates production of saliva and pharyngeal secretions. (atropine or Robinul can counteract stimulations) Automaticity heart pumps on its own
