Quite a few, depending on what sensation you're interested in,
but the cribiform plate is actually a part of the brain (the olfactory lobe), the only part of the brain that connects to the outside world directly.
Olfactory nerves located in the mucous membrane lining of the upper nasal cavity send signals representing smells to the olfactory bulb, from which the signals are sent to the brain.
Sensory impulses from the nose travel to the brain by way of the autonomic nervous system (ANS).
olfactory nerve
The olfactory nerves' main function is to transmit impulses fron our nose to the brain. It is these nerves that help us to identify smell.
The Olfactory bulb via the olfactory nerves in the nose.
the smell travels to the olfactory cells, near the top of the nose. when these cells detect the smell, the cells send specific electrical impulses to the brain, which are then interpreted by the lobe of the brain, located under the skull fissure
the olfactory (smell) and gustatory (taste) sensations pass along the cranial nerves directly to the brain. smell signals travel from the olfactory nerve (made up of groups of nerve fibres ) to a patch of the cortex located in the temporal lobe.

you can smell a bad smell in your nose is because, when you inhale, your nose takes your ,"smellings" into the nose to something that takes the materials and sends a signal to your brain, which makes a bad scent

The olfactory nerve.
nerve cells are important because they transmit everthing to our brain. they use elelctric pulses a bit like Morse code. without them we would not smell, hear,see,feel and move because the sending is a 2 way process. eg. your brain sends a message through the nerve's into the leg nerve and tells it to move and it does. the second is your organs to your brain. eg. nose send a signal to brain and message of the smell of your dinner and brain reacts and you start eating. in layment terms you could not do anything in the world except think to yourself.
Motor nerves allow the brain to stimulate muscle contraction. A motor nerve is an efferent nerve that exclusively contains the axons of somatic and branchial motoneurons, which innervate skeletal muscles (that ensure locomotion) and branchial muscles (that motorize the face and neck).
As a filter and a sensor for the brain, when you smell something it sends signals to the brain telling you what it is you are smelling.
Well, all parts of the human body has receptors. Those receptors connect with nerves and sends electrical and chemical impulses to your brain. Receptors include: skin, tongue, ears, eyes, etc.
