Exam 2 questions Flashcards
Which will cause a decrease in NE levels at an adrenergic synapse?
the action of Alpha 2 receptors on the axonal membrane and increased levels of methyl-DOPA
THe action of epinephrine on Beta 1 receptors would be…
increased strength of heart contraction (remember, B1 only are located at the myocardium)
The cells that make up the adrenal medulla
have N1 receptors in their cell body membrane
CSF is found
in ventricles, subarachnoid space and central canal
Relaxation of detrussor muscle is
beta 2
cranial nerves that have autonomic function are
3, 7, 9, 10
transverse tracts
connect the pons and cerebellum
afferent input from cardiac muscle, smooth muscle, or gland
can enter the brain through some of the cranial nerves and entering th thoracic spinal nerves convey visceral pain
proprioception is carried by
spinocerebellar and fsciculi cuneatus
muscle coordination
red nucleus
basal nuclei
cerebellum
alpha 2’s are where?
pre-synaptic side of the postganglionic neuron
interneurons are
mulitpolar and can be found in tracts
Broca’s area
premotor of frontal lobe, speech movements
referred pain in the left arm
is sensed by the brain as damage to the dermatome for that area
tract carrying pain and temperature?
lateral spinothalamic tract
