BCN I olfactory

- carries information from the olfactory receptor cells to the olfactory bulb.

- The axons of the olfactory nerves are unmyelinated C fibers and are among the smallest and slowest in the nervous system.

- Olfactory epithelium is also innervated by CN V (trigeminal), which detects noxious or painful stimuli, such as ammonia.

- The olfactory nerves pass through the cribriform plate on their way to the olfactory bulb. Fractures of the cribriform plate sever input to the olfactory bulb and reduce (hyposmia) or eliminate (anosmia) the sense of smell. The response to ammonia, however, will be intact after fracture of the cribriform plate because this response is carried on CN V.

The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
