- from midbrain = CN 3 (oculomotor) + CN 4(trochlear)
- from lateral of pons = CN 5 (trigeminal)
- at lower border of pons = CN 6 (abducens) + CN 7(facial) + CN 8 (vestibulo-cochlear)
- from medulla = CN 9 (glossopharyngeal) + CN 10 (vagus) +CN 11 (accessory) + CN 12(hypoglossal)
Simply for addition, you must know that:
- CN that emerge close to midline = CN 3 + 6 + 12
- CN that emerge more laterally = CN 5 + 7 + 8 + 9 + 10 + 11
- The only CN that emerge from dorsal aspect = CN 4

How many nerves are in your eyes?
Each eye has one nerve for vision, the optic nerve, Cranial Nerve II. Nerves are actually bundles of many nerve fibers. There are nerves that supply impulses for the muscles associated with the eyeballs so they can move are the Cranial Nerve III, Oculomotor, Cranial Nerve IV, Trochlear, and Cranial Nerve VI, the Abducens nerve.
How is the cerebellum physically connected to the brainstem?
The brainstem sits between large organs -- the brain (including cerebrum and cerebellum) and spinal cord -- and is directly connected to them. The three segments of the brainstem (the midbrain, pons, and medulla) also give rise to most of the twelve cranial nerves (excluding cranial nerves I, II, and arguably XI).
How are the 31 pairs of spinal nerves distributed throughout the human body and what functions do they serve?
The 31 pairs of spinal nerves are distributed throughout the human body, with each pair connected to a specific region of the body. These nerves serve important functions such as transmitting sensory information from the body to the brain and controlling muscle movements.
How are cranial nerves named and numbered?
Cranial nerves are named based on their function or the region they innervate. They are also numbered based on their location from anterior to posterior as they emerge from the brain. There are 12 pairs of cranial nerves, each with a unique name and number.
