Hey there!
There are different types of nerves. Some of them are sensory nerves like the ones in your hands and feet, and some complete other functions. However, they all originate from somewhere.
Cranial nerves originate from the brain itself, and spinal nerves come from the spinal cord. Damaging any can cause serious injury like death and paralysis. There are 12 cranial nerves in the nervous system, and 10 out of 12 originate in the brain stem.
Hope this helps!

Based on the image, it seems that the picture is of the layers of the atmosphere. Now the B layer is the thermosphere. It is found in between the mesosphere (layer below) and the ionosphere (layer above). It extends up to 600 km high and you can find satellites and the aurora here. Temperature here is higher as the height increases and it is because of this trait, its name thermosphere was based on on. "Thermo," in Greek means heat. It overlaps with the ionosphere.
The endoplasmic reticulum (particularly the rough endoplasmic reticulum) has ribosomes attached to it, a type of organelle that synthesizes protein. It also itself folds proteins in sacs on its surface called cisternae.
The question, however, most likely is referring specifically to ribosomes, as these are the organelles primarily responsible for the production of proteins. The endoplasmic reticulum is mostly to assist the ribosomes and transport the proteins once they are properly folded.
