the neural pathway from the spinal cord to the target tissue has two neurons, the
preganglionic neuron and the postganglionic neuron.

b) slowly decrease the frequency of action potentials generated to a constant stimulus.
c) are attune to changes in a parameter, not the extent of that change.

16) explain the kiss-and-run model of synaptic vesicle exocytosis, and how it differs
from the classic model.
17) the chambers of the heart that pump blood into the arteries are the ________.
18) ________ is the extracellular component of connective tissues.
19) the blood-brain barrier protects the brain from harmful substances in the blood, but
it also protects the brain from potentially therapeutic chemicals that may reduce the size
of brain tumors by killing cancer cells, alleviate depression, and aid in patient recovery
from stroke or spinal cord injury. two methods are currently being rigorously researched
to get these helpful chemicals past the blood-brain barrier. the two methods are termed
"molecular trojan horse" and osmotic "blood-brain barrier disruption." based on their
names, hypothesize how these methods might allow chemicals to pass through the
blood-brain barrier.
