The flashcards below were created by user mikepl103 on FreezingBlue Flashcards. What would you like to do?


  1. what is the difference between synaptic vesicles and synaptic granules?
    synaptic vesicles are smaller and contain amino acids and amines and synaptic granules are bigger and contain peptides
  2. what does the term membrane differentiations mean?
    dense accimilations of protein adjacent to and within the membranes on either side of the synaptic cleft
  3. what are the membrane differentiations on the presynaptic side claled?
    active zoes
  4. what is the membrane differentiation on the postsynaptic side called?
    postsynaptic density
  5. what are gray's type I and II synapses?
    gray's type I synapses are synapses in which the postsynaptic side is thicer than that on the presynaptic side. gray's type II synapses are synapses in which the membrane differentiations are of similar thickness. gray's type I are usually excitatory while Gray's type II synapses are usually inhibitory
  6. what are the names of the different types of connections between neruons?
    if the postsynaptic membrane is on a dendrite, the synapse is said to be axodendritic. If the postsynaptic membrane is on the cell body, the synapse is said to be axosomatic. Sometimes, two axons can synapse with one another, which is called axoaxonic. Two dendrites synapsing is dendrodendritic
  7. what accounts for the reliability of neuromuscular transmission?
    one factor is the side of the synapse-- very large. the presynaptic terminal also contains a large number of active zones. In addition, the post-synaptic membrane, also called the motor end-plate, contains a series of shallow folds. the presynatpic active zones are precisely aligned with tese folds and the postsynaptic membrane of these folds is packed with nt receptors
  8. what are the three categories of nt?
    amino acids, amines an peptides
  9. what are the proteins that concentrate neurotransmitter into the vesicles called?
    transporters
