Step 1: The Chemical Synapse An action potential arrives at the end bulb. Step 2: The Chemical Synapse Ca++ enters the presynaptic terminal. Step 3: The Chemical Synapse Ca++ interacts with the synaptic vesicle and fuses with the presynaptic membrane. Step 4: The Chemical Synapse Neurotransmitter is released and binds to the postsynaptic transmitter receptor. Step 5: The Chemical Synapse Receptor protein undergoes a change in shape that allows ions to flow. Step 6: The Chemical Synapse...

NSC Chapter 5 Test with Complete Solutions transporters - Answer-special proteins embedded in the vesicle membrane that concentrate neurotransmitters inside the vesicle once the amino acid and amine neurotransmitters are synthesized in the cytosol and then taken up by the synaptic vesicles. voltage-gated calcium channels - Answer-following the depolarization of the terminal membrane, these channel proteins open and let in Ca++ ions; resulting elevation in the ions is the signal that causes n...

How Neurons Integrate Information- Through dendritic spines, a neuron can establish more than 50,000 connections to other neurons - Nerve impulses traveling from other neurons bombard the receiving neuron with all manner of inputs (excitatory and inhibitory) - The cell body, located between the dendritic tree and its axon, can receive inputs from many other neurons Saltatory ConductionMyelin and Node of Ranvier Node of RanvierPart of an axon that is not covered by myelin Tiny gaps in the myeli...

__ spindle afferents encircle intrafusal muscle fibers and report changes in muscle length and speed of extrafusal fiber contraction - 1a A bundle of nerve fibers + intervening endoneurium bounded by a ring of perineurium is called ____. The blood-nerve barrier protects this compartment. - Endonuerial Compartment a condition caused by damage to the thalamus resulting in burning or tingling sensations and possibly hypersensitivity to things that would not normally be painful such as light to...

CBNS 120 MIDTERM 2 REVIEW QUESTIONS AND ANSWERS, GRADED A+/ VERIFIED. "M" potassium channels (check all that apply): - have a relatively high open probability at Em - are inhibited by PIP2 - mediate the late slow IPSP - mediate the late slow EPSP - cause an excitatory response through decreased resting conductance have a relatively high open probability at Em, mediate the late slow EPSP, cause an excitatory response throughterm-48 decreased resting conductance. The following cells ...

A postsynaptic potential is excitatory (EPSP) if the ion involved has a reversal potential (Eion) that is more depolarized than the resting membrane potential (Vm or Vrest), even if that Eion is hyperpolarized to the threshold for firing an action potential. - False why?>> For a postsynaptic potential to be excitatory, the reversal potential for the ion involved must be depolarized to the threshold for firing an action potential. An EPSP increases the likelihood of firing. If Eion is...
