Explanation:

Cranial Nerves are a set of 12 nerves that originate directly from the brain and exit it through holes called cranial foramina, at the base of the brain rather than exiting through the spinal cord. These nerves are rsponsible for transmitting information from the brain to head and neck regions of the boday and vice versa.

The facial and the trigeminal cranial nerves are responsible for facial movement and taste and for face sensation and chewing, respectively.

The trigeminal nerve is the largest of all the cranial nerves. It has three branches: ophthalmic, mandibular and maxillary nerves.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
