GENERAL HISTOLOGY

Detailed explanation-1: -The cerebrum is the largest portion of your brain that sits above your brainstem. These two pairs of cranial nerves include: Olfactory nerves that affect your sense of smell. Optic nerves that affect your ability to see.

Detailed explanation-2: -Their axons travel with the cranial nerve to their respective ganglia, where they synapse with the cell bodies of the postganglionic portion of the pathway which will go on to provide autonomic innervation to things such as muscles and glands.

Detailed explanation-3: -Cranial nerves and spinal nerves Nerves that directly connect the brain and the brain stem with the eyes, ears, nose, and throat and with various parts of the head, neck, and trunk are called cranial nerves.

Detailed explanation-4: -Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), of which there are conventionally considered twelve pairs.
