Question

1. Why are neurons unique?
   a. They are found solely in the central nervous system
   b. They are capable of generating an action potential
   c. They have molecular motors that can generate tension to move bones and tissues
   d. They have channels in their cell membranes
   e. They are the only cells in the body with a membrane sodium concentration gradient

Answer 1

Neurons are unique because they have molecular motors that can generate tension to move bone and tissues.

Answer - c. They have molecular motors that can generate tension to move bones and tissues

For the movement of bones and tissues, the muscle fibers of skeletal muscle need to shorten in the skeletal muscle and that force exerted during the shortening called the muscle tension.

Every group of muscles is supplied by a single motor neuron of motor units. When there is the presence of a large number of motor units occur in a muscle their the maximum force created and the muscle contraction occurs.
