Sistema ning pamamau

Ing sistema ning pamamau o olfactory system ya pin ing a gagamitan king bau. 
Deng accessory olfactory system senses pheromones. Keraklan, piyayabe 
re ing sistema ning pamamau ampo sistema ning pamanlasa 
(gustatory system) at awsan do reting chemosensory senses uling pareu dong 
ta-transduce o lilikas deng sinyal a chemical 
(chemical signals) keng perception. Sinambut ya i [[Linda B. 
Buck]] ampo i Richard Axel ketang 2004 [[Nobel Prize in Physiology or 
Medicine]] uli na ning obra ra tungkul king sistema ning pamamau.

 Ing kayang pangabalangkas (anatomy) 
Bibilugan de reng mapilan a myayaliwang dake ning utak ing sistema 
ning pamamau. Oyni ing listaan da reng mapilan a dake ning utak a maki 
kaugnayan kaniti: 
 Kilwal ning utak
 Olfactory epithelium (in the nasal cavity)
 Vomeronasal organ
 Olfactory nerve
 Kilub ning utak
 Olfactory bulb
 Piriform cortex
 Amygdala
 Entorhinal cortex

 Gamit (function) 
Atin yang mapilan a dapat o obrang kaylangang gawan ing sistema ning pamamau:
 Ilarawan ya itang bau
 Pakibalwan nung makananu ya karakal o kasikan (concentration) ing bau 
 Kilalanan ya ing bayung bau karetang baung sadya na king paligid
 Kilalanan ya itang bau nanuman ing sikan o karakal (concentration) na niti 
 Iparis ya o itulid ing bau ketang atatandanan nang uri o kabalduga’na niti

Ba nong agawa reng eganaganang obrang deti, dakal lang dake ning utak deng 
gagamitan ning sistema ning pamamau. Malyari lang ma-encode deng pamilarawan 
(representations) ning bau king lugal (mangabaldugan ya ketang bau ing metung a 
pattern da reng cellula nerviosa (neuron) king leparan ning 
metung a olfactory region); panaun (mangabaldugan ya ketang bau ing metung a 
pattern da reng action potential da reng dakal a neuron), o metung a 
pamiyabe o kombinasyun da reng adwa. Mipagdibati la pa reng siyentipiku nung 
keraklan temporal (king panaun) o spatial (king lugal o karinan) ya ing odor 
code. 

Asisingut do reng mammal deng odorant kapamilata’nng arung, nung 
nukarin la tatagkil king olfactory epithelium. Ta-
transduce (lilikas) do reng olfactory receptor 
neuron king olfactory epithelium deng kauryan ning molecule da reng odorant 
kareng sinyal a electrical, a dadalan king olfactory 
nerve papunta king olfactory bulb. Milulupung-lupung 
la king olfactory bulb deng fibras nerviosas (axon) ibat kareng 
olfactory sensory neuron bang bumilug tela-buknul a awsan dang [[glomerulus 
(olfaction)|glomerulus]]. Kilub ning glomerulus, mitatagkil la reng fibra 
nerviosa o axon kareng dendrite da reng [[:en:mitral 
cell|mitral cell]] at aliwa plang uring celula. Paparla do reng mitral cell 
deng karelang fibra nerviosa o axon kareng mapilan a dake ning utak, alimbawa 
king piriform cortex, king medial amygdala, ampo king [[entorhinal 
cortex]].

Mapalyaring ing piriform cortex ing dakeng maki maragul diling kaugnayan 
king bau. Maki kaugnayan ya ing medial kareng gagawang social o 
pamakiugnayan kareng aliwang animal, amti ing pamisiping (mating) at pamangilala 
kareng aliwang animal a kalupa da species. Tungkul naman king memorya o 
pamanandanan ing obra ning  entorhinal cortex. 
Panigaralan da pa at pisasabyan king ciencia ing eksaktung obra da reng mangatas 
a lugal ning utak a reti. 

 Kabaldugan para king pamanulu 
Malyaring yang mika diperensya ing sistema ning pamamau kapamilata’ning 
traumatic a pangasugat ning utak, [[:en:cancer|cancer\\, 
pamanyingut king asuk a makalasun, o neurodegenerative diseases (sakit a 
makasira king sistema nerviosa) anti king  Parkinson's 
disease ampng Alzheimer's disease. Malyari lang 
maging sangkan ning  anosmia deng kabilyan a reti.
