Answer:
The answer to the question: Electrical impulses or action potentials (AP) cannot propagate across a synaptic cleft. Instead, neurotransmitters are used to communicate at the synapse, and re-restablish the AP in the post-synaptic cell, would be, true.
Explanation:
Essentially, although the CNS, PNS and ANS (Central Nervous System, Peripheral Nervous System and Autonomic Nervous System) are electrical systems, that use the electricity generated through action potentials, that in turn, are created by the exchange of electrically charged ions from within and without the neuronal cells, these electrical impulses do not pass the pre-synaptic, and post-synaptic cleft. Instead, once an AP has reached the terminal end of the pre-synaptic neuron, neurotransmitters are released by this one, into the cleft, which are then taken up by the receptors present in the post-synaptic neuron. Depending on the type of transmitter released, there will be an inhibitory or excitatory effect. Then, with the transmitter attached, the post-synaptic neuron will depolarize and a new AP will be generated in the post-synaptic neuron, which will carry on. Messages, thus are transmitted that way between neurons, and also, between the nervous system and the organs they influence.

Answer: B). Managing the air way.
Explanation:
In the case of the facial trauma, the ventilation and breathing becomes labored for the victim. Hence stabilization of breathing is necessary to provide life to the victim. The air passage should be manage that is if patient is not able to respire through nose mouth opening should be manage to save life.
In the given condition the face has been affected by the collision thus air way should be managed.

Rostral
Explanation:

In particular, acyclovir is useful to treat Herpes zoster.
Viruses are tiny organisms that are able to cause infections in host organisms while using their machinery for replication. Antivirals need to be taken in order for stopping the growth of a virus in the body.
Acyclovir is used to treat infections that are caused by Herpes viruses. Acyclovir drug has an antiviral broadspectrum against the herpes diseases such as herpes zoster.
Herpes zoster is a viral infection that is caused by the same virus that causes chickenpox i.e varicella-zoster virus (VZV). The person sees rashes on his body along with pain in this viral attack. Acyclovir is administered to treat the Herpes zoster.
