exam 2

Question 1

action potential in neuron

Answer 1

-dendrite receives info
- cell body actives or suppresses the info
- axon hillock generates the action potential
- depolarization down the axon… myelinated is quicker, saltatory conduction in soatic NS
- telodendria have synaptic boutons that release the neurotransmitter into the synapse

Question 2

how does the telodendrion get energy

Answer 2

mitochondria stores ATP inside the bouton

Question 3

En passant synapse

Answer 3

located in CNS to store neurotransmitter

swellings that release neurotransmitter allowing additional synapses between other cells.. one neuron can affect multiple effector cells

Question 4

4 neurotransmitter fate

Answer 4

-diffuses from synapse
- degraded up enzymes
- uptake into pre-synaptic cell
- uptake into surrounding cells
