Yes. A dermatome is a segment, or area, of the skin that has on innervation into a spinal nerve root. What is fascinating about this is that the nerve root does not only serve the skin in that area, but also the muscle, bone, and organs associated with that specific dermatome nerve root.
The spinal cord is not a bone. It is nerve fibres and associated tissue enclosed in the spine.
It is a yellow, bone-like material under the enamel and cementum. It contains nerve fibers.
The bones that give passage to the olfactory nerve fibers are the cribriform plate of the ethmoid bone. The olfactory nerve fibers pass through small openings called cribriform foramina in the cribriform plate, allowing them to enter the nasal cavity and transmit sensory information related to smell.
NoThe Ulnar nerve is a sensory nerve that is impacted when you hit your 'funny bone'It innovates muscles in the hand and has no connection to the eye - It may make it water when you hit your 'funny bone' though but that is the pain of it rather than any direct connection!
Bone is quite different from nerve tissue. It is not an excitable tissue.
cribriform plate make up the ethmoidal labyrinths. Their walls form most of the inner walls of the eye sockets and are joined together by a thin perforated plate of bone at the roof of the nose. This bone, the cribriform plate, transmits the olfactory nerves that carry the sense of smell.
The dermis, or lower layer of the skin, contains blood vessels and sensory nerve endings
