Answer:

e. whether or not the impulse begins in the CNS

Explanation:

Nerve impulse is action potential movement through the axon. Nerve impulse propagation has its velocity (speed at which nerve impulse travels down the axon) which depends on many factors. For example, myelination increases the conduction velocity. Also, the larger the diameter of an axon, the higher the velocity is. Nodes of Ranvier present on the axons, and myelin sheath between the nodes act as a good electrical insulator which also increases the velocity.

Whether or not the im_pulse begins in the C_NS does not influence the time necessary for a nerve impulse to be transmitted.

What is the C_NS?

The Central Nervous system (C_NS) refers to the organism system used by the body to receive and transmit signals from the environment.

  • The central nervous system is composed of cells called neurons, which contain prolongations called axons.

  • During a nervous stimulus, the axons serve to communicate different nerve cells.

In conclusion, whether or not the impulse begins in the C_NS does not influence the time necessary for a nerve impulse to be transmitted.
