Neurons have extremely long cytoplasmic extensions.Their chemical signals are produced in one portion of the cell,but released from a distant location.How are the chemicals transported?
A)On myosin filaments
B)On intermediate filaments
C)On microtubules
D)On the Golgi apparatus
E)Via lysosomes

Question

Quizplus · Accepted Answer

Microtubules are part of the cytoskeleton of neurons and act as highways for the transport of vesicles containing chemicals, organelles, and other materials from one end of the neuron to the other. This transport system, called axonal transport, is crucial for the proper functioning of the neuron. Myosin filaments are involved in muscle contraction, intermediate filaments provide structural support, the Golgi apparatus is involved in processing and sorting of proteins, and lysosomes are involved in the breakdown of cellular waste.
