__ 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...

Secretion definition - the process of converting an electrical signal (presynaptic neuron) to a chemical signal (synapse) and then back to an electrical signal (post synaptic neuron) Synaptic Activity - allows neurons to communicate with one another What happens in Secretion? - the release of neurotransmitters Neurotransmitters - derived from amino acids (dopamine or norepinephrine) - derived from gas (acetylcholine) - carries chemical signal/messages Vesicle - stores neurotransmitters - tra...
