Of how many motor units is this soleus muscle composed ?
Answer in whole numbers, with no decimal places.A myelinated nerve fibre has a conduction velocity of 118 m/sec and internode lengths of 1.1 mm. How long does it take an action potential to spread from one node of Ranvier to the next ? Answer in milliseconds to 3 decimal places.
m has a conduction velocity of 137 m/sec. If its length from the spinal cord to the muscle it innervates is 1m, how long would it take an AP at the cell body (in the spinal cord) to reach the muscle ?
Answer in seconds to 3 decimal places.A Beaker is divided into two chambers, A and B, by a semi-permeable membrane lying across the middle of the beaker.
Chamber A contains the following concentration of ions:
{Na+} = 58 mM,, {K+} = 141 mM, {Cl-} = 100 mM, {A-} = 106 mMChamber B contains the following concentration of ions:
{Na+} = 200 mM,, {K+} = 9 mM, {Cl-} = 50 mM, {A-} = 152 mMIf the membrane is permeable only to K
+, what is the transmembrane potential difference of Chamber A relative to Chamber B?
Answer in whole numbers, with no decimal places. In your answer give only the numerical (asbolute) value - i.e., ignore the sign of the answer.For the statement in the left column select the correct term from the drop down list. Terms may be used more than once.
