Neurons have long, thin processes called axons, which are structures specialized for conducting signals throughout the organism's nervous system. Some axonal processes, such as the axons that originate in the spinal cord and terminate in the muscles of the toes, can be over 1 m in length. Small membraneā€‘enclosed vesicles carrying materials essential to axonal function move along microtubules of the cytoskeleton, from the cell body to the tips of the axons. Given an average vesicle velocity of 1 Ī¼m/s, how long would it take for a vesicle to move through an axon that started in the spinal cord and ended in the toes (a distance of 1 m)?

Answer:

1,000,000s

Explanation:

A micrometer (Ī¼m) is equal to 1 x 10ā»ā¶ m

This means that 1 m = 1 x 10ā¶ micrometers or 1,000,000 Ī¼m.

You can calculate the time it would take using the formula:

[tex]velocity = \dfrac{distance}{time}[/tex]

So based on the formula above, you can derive the formula for time which will be:

[tex]time=\dfrac{distance}{velocity}[/tex]

Distance = 1m or 1,000,000 Ī¼meters

Velocity = 1Ī¼m/s

We just plug it into our formula:

[tex]time = \dfrac{distance}{Velocity}\\\\time=\dfrac{1,000,000micrometers}{1micrometer/s}\\\\time=1,000,000s[/tex]
