!Nose – Olfactory System / Nerve
!!Anatomy
Olfaction is the most complex of human senses. It is closely connected to ((Digestive - Mouth, Tongue - Endodermal Mucosa|gustatory)) and tactile perception, to signal substances' useful- or harmfulness. Bad smell can create disgust and nausea to __protect__ us from ingesting poisonous food. On the other hand, good smells __stimulate ((Digestive - Mouth - Salivary Gland Ducts|salivation))__ and ingestion. These functions are coupled to the autonomous ((Nervous - System Overview|nervous system)) and the brain stem. 
Moreover, olfaction reacts upon social and sexual stimuli: pheromones aim at __sexual attraction__ through fragrances.

The __receptors__ of the olfactory epithelium are situated in the upper ((Sensory - Nose Overview|nasal cavity)) on the dendrites of the olfactory sensory neurons which are connected to the olfactory bulb, an evagination of the brain. The receptors are specified for certain fragrances. 

Both __olfactory bulbs__ are interconnected and send axons with the tractus olfactorius to the olfactory cortex, the hypothalamus and the limbic system.

!!Mind
!!!Theme:
1. Smelling, (social) recognition
2. Scent (survival)

!!!Emotions, Thoughts:
1. __Uncertainty, or resistance__ 
*What is this about?
*This stinks.
*I can't smell him/her or this situation anymore.
*I can't recognize what she wants.
2. __Strong attraction or repulsion__
*I need to get this!
*This is bad for me!
*I need my sense to be acute. 
*I have to figure that out
!!!META-Meaning:
*My nose provides me with all the air and information I need. 
*When I don´t like what I smell, I now can change it or create a distance.

!!Organ
1. (CC) sensitivity changes according to __O__uter __S__kin/Epidermis pattern with decrease in stress phase
!!!Stress Phase Symptoms:
1. (CC): Reduced perception of certain smells, or complete loss of smell (__hyposmia__, anosmia).
2. (BS): __Heightened acuity__ of the sense of smell, often accompanied by increase of mucus/lubricant production (runny nose)

!!!Regeneration Phase Symptoms:
1. (CC): At the beginning of the regeneration phase, there is glial swelling in the olfactory fibers and an __acute loss of smell__ (anosmia) may occur.
During the regeneration phase the sense of smell usually returns, depending on stimulation.
2. (BS): Sense of smell reducing to normal levels. At the beginning of regeneration, a strong underfunction can occur.

!!!Healing Peak:
1. In the healing peak, there is a temporary loss of smelling sense.
2. Temporary hyperacuity like in stress phase, accompanied by chills.

!!!Biological Meaning:
1. By the reduced smell in stress phase, the social conflict is defused.
2. Sensory acuity helps to find the desired chunk or prey.

!!Social
!!!Examples:
*1. Wife did not want to smell ‘unbearable odor’ from husband anymore to the point where she lost all sense of smell.
*A nurse disengages her sense of smell at work in order to be able to take care of the patients.
*A man falls in the night after a rich meal and cold beer, and gets a concussion. Since then his sense of smell is reduced to perceptionof smoke. (This is not to be explained by the concussion alone, as olfactory bulb and -nerve are pliable structures embedded in liquid. Biochemical changes happened to the receptors - a conditioned reflex! [http://www.tasteandsmell.com/mar08.htm|source]) (Liz, MHU Archiv)
*2. A business owner missed the opportunity of expanding because he didn´t “smell it” in advance to be prepared. He reacted with both hyperacute sense of smell and hyperactive thyroid.

!!Additional information
This conflict is similar to those concerning the nasal mucosa and the paranasal sinuses and the reaction in these tissues are coupled to changes in the sense of smell.   

!!!Constellation:   
__Smelling __(olfactory relays of both hemispheres active): Hypersensitivity to smell, smell hallucinations, smell paranoia. This can be coupled to territorial conflicts/constellations by an olfactory trigger.

!!!Differential Diagnosis:
__((Sensory - Nasal Mucosa / Ectodermal|Nasal and Parasinus Mucosa )) / Ectodermal__ (Cerebral Cortex -/+): reduced olfactory sense in stress phase (smell/recognition), hypersensitivity with inflammation and sneezing in regeneration phase.

__((Sensory - Nasal Mucosa / Endodermal|Nasal and Parasinus Mucosa ))/ Endodermal__ (Brain Stem +/-). enhanced olfactory sense, later cell proliferation/polyps in stress phase (scent of prey or danger), in regeneration these are degraded with bacterial/mycobacterial activity. Purulent rhinitis.
